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 ...

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 ...

'Breathe in . . . breathe out. Simple respiration is what keeps us alive, and your engine is no different. On a normally aspirated engine, atmospheric pressure pushes air in through the carb, intake ...

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 ...

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 ...

This collection of cam-related phenomena is intended to take you beyond the degree-it-in and set-the-valve-lash plateau. In concert with what you may already know about camshaft types, selection, and ...

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 ...
