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 ...

Of all the engine components that are often changed when modifying an engine, the cam and related components are some of the most critical. Pick the wrong combination of parts and the advantages of ...

It might seem like a bad move, but there are two major reasons why automakers are fitting their cars with plastic valve ...

A small gap with big importance in the performance and health of an engine - here's everything you need to know.

While the engineering community continues to explore the benefits of electric and hybrid vehicles—i.e., the environmental and renewable energy factors—the automotive market is still dependent on ...

Inside the engine are several fascinating parts, which you can see in Figure 7-8. At the top are the cylinder heads. These contain the mechanisms that allow the valves to open and close, letting the ...

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 ...

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 ...
