Diagnosing fuel delivery problems has become far easier for DIY mechanics and professionals thanks to compact diagnostic tools designed for modern engines. A quality fuel injector tester is essential ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...

The earliest and simplest type of fuel injection, single-point simply replaces the carburetor with one or two fuel-injector nozzles in the throttle body, which is the throat of the engine’s air intake ...

Anyone who has gone to school to learn how to repair engines of all types, such as myself, will have learned the fundamentals of how they work. It's crucial for troubleshooting and diagnosing engine ...

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 key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

What is gasoline direct injection and how is it different from traditional methods of getting fuel into your car's engine? Antuan Goodwin Senior Writer, Electrified Cars Antuan started out in the ...

Long before electronic fuel injection or even performance Holley carburetors, high-end racers operating primarily at wide-open throttle used a purely mechanical, constant-flow fuel-injection system ...

and was designed to offer a more consistent method of delivering fuel. How does mechanical fuel injection work? Early mechanical fuel systems typically relied on a complicated fuel pump that would ...

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 ...

The question of which is better, carburetion or fuel injection, really comes down to cost versus performance. Overall, more torque can usually be produced by a longer ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...
