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 ...
The valve timing of an engine is set to give the best possible performance. This means that the valves must be opened and closed at very precise times. The traditional way of showing exactly when the ...
Getting air in and exhaust gases out of the combustion chamber under all speeds and driving conditions is essential for a car’s fuel efficiency and low emissions. That’s why virtually all Chevrolet ...
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 ...
Valve timing is the most important factor determining an engine's character. A good illustration of this is provided by the following curious historical fact. In 1947 the Standard Motor Company of ...
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 ...
Honda's Valve Timing and Lift Electronic Control (VTEC) is arguably the most well-known engine type in the world. The essence of Honda's VTEC system lies in its ingenious approach to valve control — ...
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 ...
It is estimated that there are around 10,000 moving parts within an average internal combustion-powered car. Put like that, it is a truly mesmerising feat of engineering to get all of those components ...
