Modern trucks rely heavily on precise fuel delivery systems to maintain performance, fuel economy, and emissions control.

Over time and miles, your car might start to slow down. It might not accelerate as quickly as it once did; the engine may not run as smoothly as you remember, or the fuel economy may dip—but ...

Fuel injectors don't just deliver fuel. They meter it, shaping the spray so the air-fuel mixture burns in the way the engine wants it to. When deposits build up, injector fuel flow can decrease and ...

Aftermarket fuel injection systems have been on the shelves for a number of years, but early systems had a variety of bugs and technical problems that turned do-it-yourselfers off to the idea of ...

The controversy between carburetors and EFI has always been about complexity and price. Carburetors are simple—EFI is not. Carburetors are cheap—or at least cheaper than EFI. Those points have not ...

Most new petrol cars you see today are equipped with fuel injection systems or injector motors. These have almost wholly supplanted older carburetor motors. They are more reliable, effective, and ...

Don't get us wrong. There's absolutely nothing wrong with a carburetor. These largely mechanical devices have delivered precise amounts of air and fuel into engines from the very first internal ...

Diesel engines have a steadfast reputation for reliability, longevity, and pumping out gobs of grin-inducing, low-end torque. The latter makes diesels preferable over gas engines for hauling, towing, ...
