Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

While carbon buildup happens on essentially all engines, gasoline, diesel, N/A, or boosted, it's an increased concern in GDI engines. Standard Electronic Fuel Injection features injectors higher in ...

Diesel engines are torquey and efficient powerhouses capable of outlasting a comparable gas engine. But despite their robust build quality and beefier internals, there are things to avoid if you have ...

Electronic fuel injection is better for its efficiency, but installing it in a car that wasn't built for it requires ...

Never fill new filters with fuel before installation (you'll pour in dirt). Fuel-tank breathers stuffed with porous filtering media, or vented tank caps with no breathers, pull in lots of contaminants ...

Refuelling and tending to a diesel engine can cause confusion among uninformed or inexperienced users. In addition to accidentally refilling the fuel tank with gasoline instead of diesel, some ...

Having fuel injectors on all mass-produced vehicles is one of the biggest automotive breakthroughs of the past few decades. If you've ever gone through having to start an engine with a poorly tuned ...

Fuel-water separators have greater water-removal capabilities to better protect unit injectors, Caterpillar says, and deliver longer secondary fuel filter life. The separator removes 98 percent of ...

A laboratory duplication of ice crystals clogging the Fuel-Oil Heat Exchanger on a Rolls-Royce Trent 800 engine is shown in photo from NTSB, Safety Recommendations A-09-17 and A-09-18. Credit: NTSB ...

While diesel may not be the most popular fuel source for passenger vehicles, it's still extremely common. These engines are responsible for powering more than you may realize, and diesel motors can be ...
