Compression release. The decompression valve (black lever) on a Yanmar YSB8 marine diesel engine. A compression release mechanism works to ease the starting of internal combustion engines by allowing them to rotate to starting speed without having to work against the compression of the pistons.
3 lis 2016 · Some engines, especially small engines, have compression release valves so that it's easier to turn the engine when you first start it because there is less compression in the cylinder. Examples would include the Ducati 1199, or more in my field, the Kohler CV460S.
A compression release engine brake, compression brake, or decompression brake is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaust valves to the cylinders, right before the compression stroke ends, releasing the compressed gas trapped in the cylinders, and slowing the vehicle.

17 cze 2022 · Understanding the Compression Release System. The compression release system works by opening the engine’s exhaust valves during the compression stroke, allowing the compressed air-fuel mixture to escape before the power stroke.

It does this via either a release valve that is incorporated within the cylinder head that vents the cylinder pressure to the outside atmosphere until the engine has sufficient momentum to overcome it, or by venting straight through one of the main valves.
