    Understanding an Engine through thermodynamics

    I have to do a thermodynamics project where I research parameters (as many as possible) for a gasoline engine cycle and analyze its performance. "You can make any reasonable assumption to complete the analysis. Discuss the difference between the performance of your model and actual devices. Explore any potential improvement."

    I am having trouble finding a logical way to convert the spark of an air fuel mixture to a Qin which we would find in our equations. I know that "potential improvements" are just limitless but I need to keep them related to thermo (or just have a good explanation )

    I wanted to see if anyone has done something like this before or if anyone had some good specifications of some kind of LSx motor (or LM7 etc...).

    Really any related information would be greatly appreciated.

    Thanks,
    Michael

    I really can't help, but would love to hear what you come up with in the end. Be sure you post up your project when you are done.

    Good luck.

    Use The Google...there's probably tons of stuff out there. My thermo classes were far too long ago to be any help...
