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 ...

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 ...

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 ...

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 ...

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 ...

Jacobs Vehicle Systems, a manufacturer of heavy-duty diesel engine retarding systems and valve actuation mechanisms, has launched a new 2-Step Variable Valve Actuation (VVA) system. By enhancing ...

It may not be pleasant, but setting the valve lash on a high-performance engine is a skill that must be learned. The reality is that even the most savvy engine masters had to learn about lash at one ...

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 ...
