The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, an engine’s efficiency is dependent on a precisely calculated air-to-fuel ...

Lots of new car engines these days are built with both port and direct fuel injection. On the surface, that might not make much sense. Why would a carmaker use two different types of injection methods ...

Turbo Fuel Stratified Injection technology for gasoline engines was once a remarkable innovation that has since become quite commonplace. Traditional fuel-injected engines that don't use direct ...

It's an amazing time when there's new technology in the industry as it forces a new rivalry in speed parts, and direct-injection is firmly in the high-performance arena whether anyone likes it or not.
