Variable valve timing and lift can dramatically change an engine's power output and efficiency. Here's how they work.

The Honda Chimney Engine represents a bold leap forward in engine technology, integrating a valve within the piston and ...

Valves: Different Types And How They Work Generally speaking, valves look like inverted golf t-shirts and closely interact with rotating camshafts in your engine. They open and close depending on the ...

The valve has two primary settings: opened and closed. It closes when the engine starts up and opens in an idle or low-speed state, requiring minuscule amounts of power. However, the valve closes ...

With high-pressure air moving the valves up and down and way less moving parts, the engine rpm can go to more than 20,000, even though Guidotti says Avintia bikes only work in the 15k range.

Pay attention as we explain how exactly four cylinder car engines work. We go over all the basic component and how they work together such as the block, crankshaft, pistons, rods, etc. Then we ...

The letters VVEL are important to the architecture of Nissan engines. Those four letters stand for Variable Valve Event and Lift. What that refers to is a Nissan engine that operates without the ...

While the poppet valves work well at low speeds, they are unreliable at high engine speeds, and the “timing,” or opening and closing of the valves, is uncertain.
