My name is AD. I also a feilo driver.
I would like to share my point of view. Based on my current feasible studies,
Car performance is not measure by the how much gasoline is burn as it is the air that ignite the combustion. For a gasoline car, the air fuel ratio is 12:1 to 16:1 and for diesel is 18:1 to 25:1.
The more air is into the engine, the more power it produce. Remember the Hydrogen always cause combustion and it is due to the OXygen actually....
The performance of your car Horsepower is fully depend on how much your cylinder volume can hold. The higher the volume, the more oxygen it can do "Intake- Compression- Combustion- Exhaust"..... Of coz the quality of oxygen also plays a role, the hot oxygen have more energy because of the enthaply and internal energy. Remember why we have Turbo, it is to produce more hot Quality air.
Basically the Engine part of the cylinder are the most important criteria related car performance.....
Back than, i invested with a group in USA during my graduate time in car R&D. We invented several items..... Such as de-carbonize the car carbon in the cylinder of the piston..... If the pile up of too much incomplete combustion, that will require more work to do the drag force..thus lead to car effiency n the gasoline to work MORE....
AD Equation:
DAmm so hard to explain in work
Now i am Oil n GAs Engineer + running some small business ( few are in automotive industry), Feel free to share your experinces with ad.....
