Okay let's brainstorm here - what are all the different aspects of designing an engine from start to finish?
- CAD specialist
- chemist
- metallurgy
- motor repair specialist
- lawyer
- business manager
All those I can get from my college. What else?
You need a Specialist on computer engineering to write specific code for the computers. You also need a aerodynamic specialist to optimise the exterior.
Have you thought of leaning the mixture to 15:1 (or is it 16:1), the prime air-fuel mixture. That will increase hp and mpg in theory by 30-50% of the average car. The problem with increasing the mixture is that you have to create a stronger engine, valves need to strengthened, sparkplugs need to modified to handle the extra pressure, the rockers need to be strengthened, the valve stems need to be lightened. The Diesel engine have to be able to support thousands of psi so you should look at them to get an idea of that is needed. The whole drivetrain needs to be lightened up to allow for less rotating mass. The tranny much be a manual because there is less mass than a auto. There is always the mass of the vehicle which needs to be as low as possible, Id advise buying a Lotus Elise's chassi because its extremely light weight and strong. There are other things to think about like the aerodynamic qualities of the car. Mercedes-Benz's new fish car has the lowest drag co-efficient of .19, so Id advise you on following that.
Dont plan on adding any of those special aftermarket things like the Tornado or Water Injection because they only decrease power and mgp. Remember, 99% of hydrocarbons are burned in the chamber, so any of the aftermarkets items that claim extra mgp from polarizing oil or magnitize the gas lines dont work.
Also, many of the car companies have patents on increasing mpg and dont release them in cars all the time because the higher ups own lots of stock in gas station (like quiktrip). Of course not all of the higher ups dont own any of that stock so they push for better economy. They periodically release upgrades like BMWs new valvtronic thing, or displacement on demand tech from Chrysler. But my point is, make sure (i cant stress that enough) that you arent breaking any patent laws, and if you do get a good laywer.
