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.



 

Comprehensive deconstruction digitized Honda CR-Z to see the CR-Z

IMA system power voltage 100v peak voltage is 141V, the electric system is provided by the Matsushita Electric;




IMA system accumulator system by 7 nickel-metal hydride batteries, nickel-metal hydride battery performance than lithium battery is low, but then abandoned recycling environmental pollution;



3, nickel-metal hydride battery 3 hour discharge rate 5.75 An • the total capacity of the battery is 0.767 kilowatts •;

4, assuming the battery is fully charged, the continuous operation of the motor to the maximum output power of 14, then, in theory, 4 minutes 30 seconds after the power will all run out;




IMA cable, the maximum current up to 100 amps;



Figure: 100 amps how thick cable so as not to overload? The answer is ...

6, IMA AC synchronous motor output: 14 1500rpm 8Kgm @ 1000rpm;

7, IMA motor weight of about 34 kg, nickel-hydrogen batteries total approximately 14.3 kg, cable weighs about 10 kg and 60 kg, the total weight of the IMA;

8, the maximum torque of the powertrain 17.7Kgm @ 1000 ~ 1500rpm;

9, the outer diameter of the head, the tail section of the exhaust pipe are 43mm, 40mm and 44mm;




10, the CR-Z of the throttle valve the diameter is 50mm.
