Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...

In any automotive braking system, the linchpin factor is pressure. When you press on the brake pedal in your car, for instance, pressurized brake fluid is distributed to the pistons in wheels, which ...

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 ...

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 ...

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 ...

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 ...

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, ...

For Part I, covering the new combustion system, direct injection, and active fuel management: click here. For Part III, covering the block, crankshaft and lubrication systems: click here. Continuing ...

In the pre-LS era, a typical small-block-powered street car would rev willingly to around 5,000 rpm. You could assemble a cam package for it—even using heavy components—and you probably wouldn't have ...

The Lash Effect: Solid lifter valvetrains depend on accurate lash to make maximum power and dependability. Here’s how to do it right A properly tuned engine is an incredible mix of components all ...

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 ...
