Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...

There are currently two distinct schools of thought regarding the single problem of how a fuel injector should be designed for an automotive engine. The oldest system and one that was originally ...

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

A traditional two-stroke engine has the piston pushing down after firing, moving past an exhaust port and allowing the exhaust gases to leave the chamber. Simultaneously, as the piston travels ...

This study investigates the formation of wall films in direct injection engines, a key factor in particulate matter generation. The results show that cold fuel adheres more to the wall creating ...

Anyone who appreciates simplicity of design and efficiency of operation has to like small two-stroke-cycle engines that power construction tools such as cut-off saws, rammers and breakers. Producing ...
