Diesel injectors have gotten increasingly complex over the last twenty years of diesel development, but their basic design is fairly simple. Diesel fuel from the injection pump enters the mechanical ...

Direct injection. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...

Vehicle fuel injectors are integral to a car's engine fuel delivery system. Fuel injectors are responsible for delivering the right fuel at the right time. Gasoline and diesel-powered engines of all ...

Question: Can you explain how fuel injection works? I've been hearing about new ways this is done and realized I didn't understand the current kind. I grew up with carburetors and tinkered with them ...

The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor intended, to be run on the street. All of these ...

This overview illustration will help you place many of the different sensors used in a multipoint fuel-injection (MPFI) engine such as a 5.0L Ford or GM tuned-port-injection (TPI) 305 or 350. One ...

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 ...

QUESTION: I was having a conversation about cars with my 14-year-old son, and the topic of fuel injection came up. He wanted to know how it works, and I began to tell him but then realized I was ...

Fuel injector cleaners are additives that are poured right into the gas tank and remove carbon deposits and other contaminants from the injectors. This can lead to better fuel economy, improved ...

The fuel injector is the least understood component of the EFI system, but it is a critical part for a successful calibration. The job of fueling the cylinders comes with many design and engineering ...
