In order to set a stage for what follows, let's first revisit some of the fundamentals involved in how valve timing relates to power output. And to further clarify how "power" is defined in the ...

Variable valve timing (VVT) is generally accomplished by phase shifting the camshaft relative to the crankshaft. By phase shifting the camshaft, the valve events are advanced or retarded relative to ...

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 ...

To celebrate HOT ROD's 75th anniversary, we teamed up with CASTROL GTX to bring you some of the stories that exemplify the core of what HOT ROD is and reflect the brand's influence on America's car ...

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 ...

When you check out the features of a new car, you’ll probably be bombarded with glowing words about its engine’s “advanced valvetrain technology.” How did this happen? They don’t shower us with ...
