The exhaust valve permits the reaction products of the combustion process to be removed from the cylinder during the exhaust stroke of the engine. The valve opens at or before Bottom Dead Center on ...

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 ...

In order to move through the four stages of internal combustion, all of these bits and bobs are quite necessary. Some engines, however, take advantage of squeezing in a few more parts where they can.

Electronically controlled timing of fuel injection and exhaust valves at any load boosting performance Improved emissions Superior engine balance and thermal load Increased range of rpm possible ...

IVA also does away with timing belts and valve springs, so the engine would be lighter and, theoretically, less expensive to service. While the project is a collaboration with Jaguar Land Rover, IVA ...

Variable valve actuation of internal combustion (IC) engines is capable of significantly improving their performance. Variable valve actuation can be divided into two main categories: variable valve ...
