BMW N52 engine valve technology structure

Speaking of the valve technical aspects, I believe have paid attention to the automotive technology or some fans will understand, and TV ads are often able to see these valve technology. VVT-i, i-VTEC, CVVT, VVEL and so on, and they have their own differences. These terms represent that they have different functions, wherein the valve timing variable technology also has a variable valve timing together with valve lift technology, such as I-VTEC, VVEL both. However, these are just some Japanese engine valve technology, As regards the European Department of the engine, there exists what kind of valve technology. BMW engine series, the most common form of valve technology is the VANOS that BMW's variable valve technology. BMW has joined many engines Double-Vanos, also uses variable valve timing technology in the intake side and exhaust side. In addition Vanos technology, there is another called Valvetronic technology.

Although the N52 engine with Valvetronic technology, but only with the intake side, the exhaust side is lacking.

The principle and structure of the Valvetronic system is actually more complex compared to others such as Honda AVTEC similar systems. Valvetronic principle to change the valve lift is actually in the valve rocker an additional intermediate shaft, intermediate shaft connected to a computer-controlled stepping motor. The shaft has a semicircular circumferential rotation of the eccentric wheel. In addition, the valve rocker added in the middle of a floating arm, middle arm driven by the cam control valve opening and closing. Changing the valve lift is through rotation of the eccentric, to promote the branched intermediate arm, changing the position of the intermediate arm, so as to control the depth of the valve opening and closing. So as to achieve even in the same kind of the camshaft angle, can have from 0-10mm valve lift changes. This valve lift change is based on the engine speed, load and other conditions, and is automatically and stepless change the valve lift. Already mentioned above, the rotating eccentric use of a stepper motor, stepper motor through a worm gear worm structure to control the rotation of the eccentric axle via a computer-controlled stepper motor actuator speed is very fast. Valve lift from the shallowest to deepest requires only a speed of 0.3 seconds. I.e., in the blink of an eye will be able to complete the process of increase or decrease in the valve lift.

 

Mix and match without boundaries RX-8 Fall in love with the Honda I

Do not know whether we understand it the subject? In fact, this subject is not difficult to understand, just remember a few keywords - Mashup, RX-8, Honda can.Why do I say this? Because these keywords can be said throughout mashups means that the RX-8 and Honda had some parts mash together. But in the end what is it? Read on.

RX-8 the transplantation engine, I believe that if you have paid attention to the hearing part of our modified car, should have to pay attention to the case we have reported the RX-8 transplanted MPS L3-VDT or ordinary version of the L3-VE engine, perhaps everyone already probably know the RX-8 to transplant the engine needs to do, what areas need to make any changes, if I say introduce this modification case here as well, we should be able to feel no interest in it. But if I tell you that this RX-8 went on to say, though they are transplanted engine, but the transplant is not the same factory engine? Everyone should be able to mention affordable spirit. Here can answer before, mix together the precisely is the heart of a car - engine. That in the end is the rotor RX-8 used in the Honda car, the Honda engine used in the RX-8 body? The answer is the latter, Mracing the K24A engine Honda models transplanted to the RX-8 body. This mashup perhaps abroad once appeared, but then in the country, to the understanding of the author himself, really only this one. In the end you want to transplant the engine needs to do? In addition, compared to the pair of engine for the 13B engine horsepower low of nearly 30, so that not more change horsepower the smaller? Do not worry, these problems will be throughout the follow-up reports 11 to answer them, well, look at the first episode it.

Figure: This is a RX-8 is nothing wrong with it, but if you open the engine hatch, you will find that it is not just a simple as RX-8.

Figure: look at it this way, if we have found a problem? Not friends, then you should go look at the Honda models.

Figure: unfortunately, this car we do not have detailed to follow up on the port it every step of the engine, because when we saw it, it has been like this, however, it does not matter, because the vehicle is not yet completed, thendown and we will continue to follow-up reports for everyone.

Digitization CR-Z transmission system

Not to enumerate the various parameters of the drive system, after all these parameters together and calculated results with the reference value. The Honda CR-Z the only CVT version then, then there should be some people move to change the manual transmission brains. So small 6-speed manual gearbox parameter column, you can see from this table, pair of 6-speed gearbox or favor fuel-efficient orientation 2/3/4/5 files convergence is not too close , so if you do not retrofit pressurization system can significantly enhance the torque, and the playability of the pair manual gearbox will be greatly reduced, or even can be said if not just for the sake of the three pedals and fiddle file to the thrill of almost no replacement necessary.

The figure is a manual gearbox file Chibi, and the results of the calculation of the various parameters. Acceleration interval is low-grade swapped in the next high-end post-shift to shift into a higher gear position, how much speed range available.

Parking specialized households: Toyota & VW automatic parking technology comparison

I believe that many drivers that the car is a fun thing, on the 180-degree shift in attitude parking. In the heavy traffic of the city to find a parking space is a good car for most women is unwilling to face something difficult to stop in a not well-off parking spaces. After the car the crazy drops horn, parked the car difficult to get off even Guaceng body many drivers unspeakable pain. Fortunately, the technical development of motor vehicles to provide them to a solution, that is, automatic parking function.
Automatic parking function in many domestic models sold, is not a surprising thing, why do you want something to do Toyota Volkswagen? People do not drink the water without a source, small and will not for no reason begins. Because of the Toyota Volkswagen is the originator of the automatic parking technology Xiaobian will "August" both technical merits.
In 1992, Volkswagen automatic parking technology in IRVW Futura concept car. Fully automatic is that the driver can get off to watch the whole process of car-parking concept car luggage installed as PC-sized computer to control the parking system, but because of the expected high production costs (installation this system was to spend $ 3,000, equivalent to more than the price of a QQ), so I did not go into production. Meat and potatoes will always be someone coveted after ten years in the public is almost forget it when Asian auto giant Toyota announced that it will provide the automatic parking system on the second-generation Prius in 2003, three years later, that is to install this parking system price has dropped to $ 700 in 2006, the major manufacturers have to follow suit, since the automatic parking system gradually into the life of the masses. The face now many filled with eye parking function, small clear that the automatic parking system is not a parking assist system, automatic parking system is all hands, or just need to control the steering or braking, parking auxiliary system only after it installed a reverse image and body radar; Second, small Toyota, Volkswagen began to introduce automatic parking technology.
Speaking by Volkswagen, Volkswagen automatic parking system called "PA (Park Assist)", MAGOTAN, Tiguan, because the driver controls the brake, it is also called "semi-automatic parking system. Volkswagen automatic parking system consists of a display device, camera, radar and control computer. The radar located two bumper almost 180 degrees on both sides of the camera in the left and right rear-view mirror, front, rear, marked. We all know that parking and the partakers the SMOOTH parking and two vertical parking, small Shun column type parking as an example to explain this feature. When the vehicle speed is less than 36Km / h on both sides of the car's radar began to scan automatically find a suitable parking, more parking space and the length of the car, than the general long, 1.5 meters above the car to be considered valid parking bit. Driver simply want to make one side of the turn signal is used to imply to find which side of the parking spaces;

Automotive technology sensing wiper

Sensing wiper (Induction type wiper), different from the traditional wiper sensing wiper can automatically sense the size of the presence or absence of rainfall, and rainfall automatically work at different speeds, generally used in high-grade car.

The core components of the sensing wiper rain sensor, rain sensor mainstream market optical and capacitive two choices. Xiaobian introduce the works of these two sensors:

The ① optical. The Xiaobian be simple life experiments to make everyone look better.

The Xiaobian holding the light source (orange arrow), the other side is a mirror (white arrow). This is a very common phenomenon of life: refraction when the light will not be on the mirror surface is clean and dry; Once the mirror significant drops dependent on light scattering occur immediately, give people a sense of hazy. Optical rain sensor is the use of this principle, the interior mirror back with integrated rain sensor with a phototransistor and light-emitting diodes. When the weather is dry, did not occur due to the light refraction, the amount of the light received by the phototransistor is not changed, the corresponding electrical signal is also not changed. If it rains a wet (or glass), the light emitting diode generates the light is attached to the windshield of the rain barrier refraction occurs, resulting in the change of the amount of light received by the phototransistor. Once this change is beyond the the ECU set of range, the wiper will start, and to adapt to speed changes with rainfall. This rain sensor accuracy is very high, the only flaw is that is more sensitive to some non Raindrops objects, such as mud, insects, leaves.

 Capacitive rain sensor principle is relatively complex, to measure the rainfall is a huge difference in the use of glass and rain permittivity (dielectric constant of the glass 2, the dielectric constant of the rain for 80).
Was finger parallel to the metal plate mounted on the windshield between the inner and outer layers, wherein a set of metal plates interleaved, but does not touch the other metal plates, so that the windshield and the metal plate is formed between the dielectric. Capacitive sensors, each group of the dielectric are connected to the high-frequency balanced bridge similar to the Wheatstone bridge and the capacitance can be measured, thereby to monitor the capacitance of the capacitive sensor. Each group dielectric capacitance are not changed when the weather is dry, balanced bridge does not sense a change in capacitance, the wiper does not work; When it rains, the windshield outer surface due to rainwater infiltration into the metal plate, dielectric The constant change, once beyond the allowable range, the ECU can receive the signal and allow wiper work. Obviously, capacitive wiper according to the size of the rainfall automatically adjusts wiper speed. The advantage of this rain sensor do not need to detect light, and can be arranged in a dark location of the edge of the windshield, and the media (windshield) is ready, wiring and sensor placement is also more convenient, cost is not high. Disadvantageously, soon be scraped off under the long-term work of the wiper on the windshield outer surface of the finger-like metal strips, and cause the wiper work failure.

In addition, there are some models use vehicle speed sensor as a rain sensor to open the wiper, according to the vehicle speed to adjust wiper speed, the faster the speed, the faster the wiper speed. This "rain sensor" cost economy, only need to use the original vehicle speed sensor can be completed, the drawbacks of not open automatically, according to the rainfall size will not solve the problem if the rainfall is very slow speed.

Peugeot 508 rear view camera installation of Hawkeye lights

508 using the rear-view camera alternative, supply voltage, and image formats unconventional generic; This gives increased difficulty going to change the CCD camera; clarity of this camera during the day is good; backlighting effect can also, with the exception of the eveningvery unsatisfactory and not about. This workaround only increased illumination. Original car dual 21W halogen down lights, the brightness is passable. However, due to design considerations (estimated to be afraid to shine after the car's eye) bulb facing uprights, rely on the reflector bowls reflected light lighting, so the effect is not quite. X treasure to buy a pair of Hawkeye lights near the license 3W a lower camera position, position, full lighting of the road, as little as possible irradiation eyes. To increase the illumination, the actual results were pretty good. Share:

This is embedded, I chose this, but also anti-theft; looks coordination

This paste, the installation is relatively easy.

Installation location, to borrow a picture online, 508 licenses than this low-light to the ground better.

This is reversing lamp is illuminated. Evening look, and phone shot a little worse. . Look at the effect

Purchase a auto diagnostic device of you don’t delighted regarding pay out storage area a large buck-Vehicle Interaction Scanner

A lot of the car analysis can be on the situation of the engine, even though framework might also have devices. The sensor would certainly preserve files in the operation of the part it’s within. The data are in a variety of unique codes that are obtainable by the technician during the evaluation. Once delivered electronically, the actual codes can be interpreted to find out what will be incorrect which has a certain part of a vehicle As a result, diagnostic software inside your car will not be adequate. It must contain a car diagnostic tool that may look at files distributed by the actual diagnostic application. It is termed launch x431 diagun or perhaps vehicle signal audience. A holder can get this kind of tool to ascertain the issues of her or his automobile. This can be preferable to traversing to a auto technician, in whose investigation may cost a whole lot.
Does one want to pay out auto aspects the big bucks? A number of them possess advanced resources that conserve these people plenty of problems. That they connect these inside, have the data they require, increase the risk for required adjustments along with side the huge expenses. Something concerning this seriously isn’t reasonable. You might have experience   You understand basic principles of engines and also have carried out a number of repairs yourself. Why wouldn’t you shell out somebody else so much income with regard to auto examinations you can use your self quickly and easily? What if you could do all this in minutes for a crazy low price? You can. Some types of car diagnostic tool can even solve some of your car’s problems for you. Car diagnostic tools lexia 3 are intended for testing and programming tasks. Many of these automotive scan tools can interface directly with the new computers being built in cars. This is possible because most new cars have an OBD (onboard diagnostic computer) that constant monitors and can report on commonly malfunctioning car systems. This makes it much quicker to get your car repaired. In many cases it can save you diagnostic charges. Most importantly, it can save you from having your mechanic trying to fix the wrong parts of your car and vehicle owners are gradually becoming crack auto medics; because these tools can do virtually all the jobs that a vehicle owner will take to an auto repair center.
There are many code readers in the market, made by different manufacturers, with maybe one or two different features and they appear to be doing the same things, but taking a look at the response of customers online   autocom cdp has always top the list. It has been receiving 4 or 5 stars reviews all the way. So what are you waiting?

Peugeot planet year 2000 also can be work for automobile overheating-MD 801

Abnormal condition is employed throughout vehicles. Suddenly several automobile usage is not standard and really should always be avoidance: relocating the powerplant abruptly delayed; need stopping automobile with out braking; winter months car won’t begin   not really begin right after engine flameout; moving steering suddenly hit a brick wall; far more In addition pierce in addition to vehicle cars for instance impulsive burning hearth. Do not disregard the using release x431 diagun. Signs and symptoms more evident plus much more complicated causes, mostly within the car internal wrong doing is not focus on become an unexpected injury.
The motor is the element that’s mostly plagued by troubles, which complaints are described in certain approaches. One is by the sporting and also dimming in the serp mild. Simply because a problem with this engine that must be discovered. Another indication make fish an powerplant includes a concern is once the light-weight continuously glows. Which means that your dilemma may be either the o2 warning or perhaps an emission issue. Indefinite blinking is another signal of a concern using the engine. All of these symptoms must immediate anyone to look at the vehicle. Car seems to be unusual.
Auto parking place on the level, the particular examine will discover that will occasionally each side vertical deflection as well as horizontally skew auto, exhibiting the style of dysfunction, need to observe the examining on the fatigue pressure, body and headgear harm, body damage. The appearance of disorders that may affect the car to car use, Such as auto focus shift, severe vibration, steering instability and wandering and other vehicles. Previous content has mentioned that automotive Fault, can experience sensory and equipment on the cars performance and appearance of the symptoms of abnormalities to judge. You need to use the diagnostic tools to launch x431, lexia3, mb star c3 and so on. But of course, not everyone is willing to invest in expensive professional diagnostic tools  Amateur scanning tools are much less expensive than professional ones. The lower price means not having the full capabilities of professional tool. They can be plugged into your car’s OBD II port and they can read the codes that translate to details on vehicle functions.
In addition, the peugeot planet 2000 can be work for car overheating; car overheating car ministries showed the temperature exceeds normal temperature range. Peugeot planet 2000 is a good diagnostic tool to use. Engine overheating, the most obvious to the performance of the radiator boil; transmission overheating, overheating rear axle and brake overheating and so can be tested by hand or water test method shown, car overheating failure to do further examination to find root causes,  such as the fact a long time caused by high load, generally do not affect use. When it comes to internal organs malfunction, should be timely diagnosis and exclusion.

Honda Ma Familia approach in mind Episode

Previously adjourned to the end of the last episode of "Honda Ma Familia approach in mind the second episode," I left two questions, one hand in finishing the gearbox and engine when measuring frame impossible downtime, thatframe aspect in do? Do not know if you have not guessed, the answer is the production of the body, that is, the appearance of. When we look at the car, do not know have not paid attention to racing air force packages tend to have a very exaggerated throwing wide, in fact, the purpose of doing so is to accommodate wider tires. Wider tires have a higher grip, in the sport of racing high grip requirements, be able to get more grip means that the vehicle speed is higher, to win the chance to also increase. Some said widening tires do not like it, why throw wide fender? , Racing also need to take into account race cases, many races provisions racing tires can not be beyond the wheel arches, but Yun Xu Yizi board out throwing wide, throwing wide body can only do so in order to cater to the Regulations, before they can change into the wider tires. Of course, in addition to the requirements of the Regulations, throwing wide body Another advantage is that the aerodynamics, the reasonable thrown wide fender if it can enhance its aerodynamic design, make the vehicle more stable at high speed.

Front wheel itself has rarely thrown wide, but still not enough, also need to continue to look outward, we see that line? That is the positioning line should be original fender resection.

Side front wheel has been removed, and the remake, compared to the original throw wide the point can not be exaggerated throwing wide the main reason is that the front wheel but also on the steering and drive, so there will be some limits on the position.

The time of the shooting, the rear wheel thrown wide engineering just in construction technicians are cardboard skin depicts throwing wide the corresponding shape, produce abrasive.
