The carburetor didn't fade away — it was federally regulated out of existence.

Most modern vehicles have multi-port fuel injection (MFI) with a separate fuel injector for each cylinder. This system mixes the fuel and air together right in the intake port for eachengine cylinder ...

Electronic fuel injection is older than you think, the earliest example being the failed Bendix Electrojector system from 1957. Bosch bought the rights to the Eletrojector system and developed it into ...

The benefits and shortcomings of EFI versus carburetion is a hot and ongoing battle in the hot rod community-and one that we're not going to engage in for this feature. No, for this one we're going to ...

We used to be carburetor junkies. When fuel injection started showing up on our fullsize trucks, we were in a hissy-fit about a fuel delivery system that couldn't be readily modified. Then we finally ...

We often talk about the benefits of fuel injection on off-road vehicles. Generally, these systems run more reliably than carbureted systems, but they are, at the end of the day, a bit more complex ...

Diesel injector issues can cause rough idling, power loss, and costly engine damage if ignored. Learning to test and diagnose them yourself can save time and money. From simple listening checks to ...

Researchers have developed a promising yet surprisingly simple modification to diesel engines that could hold the key to reducing the complexity, maintenance, and size and weight of emission ...

Sandia National Laboratories researchers (left to right: Nathan Harry, Christopher Nilsen, Drummond Biles, and Charles Mueller) show off their prototype of ducted fuel injection module for diesel ...

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 ...

Although not sold in a Pontiac since 1981, the traditional Pontiac V-8 engine continues to benefit technologically from a seemingly endless array of new parts that are being developed to increase ...
