i need to design a hybrid engine for passanger car from A to Z,
i've only net brake power which is 100 kw .
but i don't know how can i start in design ? this the problem!:confused:
i could use any help
thanks

What are you learning in school that will help you with this design?
 
i learned about engine performance and total resistance on the vehicle .
actually I've learned almost everything about vehicle,
how can i start ? this is the question :confused:

Since this is for a school project, we will not do your project for you. Maybe start by looking at existing designs for hybrid engines in that power range. What hybrid vehicles have engines similar to the one you are to design? What batteries do they use? What do they use for transmissions?

Please show some effort -- it is your schoolwork project, after all. :smile:

"Design" is pretty open-ended. If the end result is to be a physical model/prototype, and you are truly responsible for "A to Z", then you have many months or years of work ahead of you.

"Hybrid engine" also leaves a lot open to interpretation. If you are referring to hybrid in the sense of vehicles such as the Toyota Prius, then it is a hybrid powertrain -- a conventional internal combustion engine with a high-voltage electrical generator and an electric motor. The manner in which the components work together varies by manufaacturer and model. Some vehicles use the ICE for primary propulsion, with the electric motor only working as a booster of sorts.

Sounds like you've already started. You say that you have the required engine parameters and the vehicle data. Where exactly are you stuck?

yes I've already start collecting a general information about parameter i need ,but i only have the brake power and i have to assuming a lot of parameter such as "mechanical efficience and clearance volume ,etc" i need to know the acceptable rang for assuming .
thanks a lot for your help:smile:

Now you're saying that you know almost nothing about the vehicle. :confused:
 
Yes, it does appear that eng/mahmoud would like us to do his project for him. Guess he's not real familiar with how the PF operates...
