This is a very interesting read. Mitsu has developed an engine that is more fuel efficient and more powerful due to a two stage direct injection engine. The fuel is injected directly into the cylinders (on top of strangely shaped pistons) in stages depending on engine load. The new engines are extemely clean and knock resistant (great for a turbocharged engine, esp. if it adapts to changes in boost levels). Its a technical read but if you can find a few minutes to skim through it I think you will find it interesting. It is rumored that the new EVO VIII's being released in the U.S. in January will have this technology. Meaning it may not be the good 'ole 4G63 powerplant anymore...but over 250 horses stock nonetheless.

That's a pretty cool concept, Marcus. How expensive is liquid O2? Theoretically you could take a 2 cycle dirtbike motor and machine the block for direct O2 injection. I guess you'd have to design a head and a fuel delivery system. Not to mention a fuel injection computer...
I imagine liquid O2 is a bit cold requiring a special fuel delivery system that won't freeze. |
