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. 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.
