Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

If we tell you that some folks take engine components made with a highly explosive metal, put them under the hood in one of the hottest parts of the motor, and then rely on those parts to actually ...

Taking care of your vehicle is vital to ensure it stays in great condition. Your brakes could give you trouble someday, or your suspension could require tinkering, inevitably leading you to an auto ...

EGR stands for exhaust gas recirculation, and the EGR valve is part of a system that does as the name implies: recirculate exhaust gas back into the engine’s intake manifold for a return trip to the ...

Original engines in cars built before the early 1970s generally don't have hardened exhaust seats that are resistant to unleaded gas. Nevertheless, tests conducted in the mid-1970s by the U.S. Army, ...

Your engine is composed of many moving parts and pieces. In order to move through the four stages of internal combustion, all of these bits and bobs are quite necessary. Some engines, however, take ...

There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

Mobility is changing — it’s electrifying. But not every vehicle is suited for electric propulsion and heavy battery systems. That’s where the rotary exhaust valve (REV) is revolutionary. The Advanced ...

Does your engine need a valve adjustment? It depends on the age, condition and brand of vehicle you’re driving. Due to the popularization of roller-follower valve train designs that reduce friction ...
