Cylinder head valves normally will not just bend unless the engine has experienced some sort of trauma. Bent valves can occur as the by-product of a timing belt failure, as the valves strike the ...

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 ...

Brian Cooley is CNET's Editor at large and has been with the brand since 1995. He currently focuses on electrification of vehicles but also follows the big trends in smart home, digital healthcare, 5G ...

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 ...

Too often, pneumatic circuits are sized based on the valve’s flow coefficient, C v, without considering other system components. In the past, focusing on the valve alone often sufficed because air was ...

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 ...

Although hybrids are becoming more popular with manufacturers – the technology being a relatively simple, cost-effective way to meet regulation and customer demand for some level of electrification in ...

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 ...

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 ...

Major and minor valve seat diameters are most easily checked for consistency with a pair of dividers during seat grinding operation. This assures proper seat width. The answer to the question posed by ...
