Shut down protection apparatus for a water cooled internal combustion engine

摘要

The invention contemplates engine shut down protection apparatus used in conjunction with an electronic fuel injection circuit for a water cooled internal-combustion engine. When turning off water-cooled internal combustion engines equipped with typical electronic fuel injection systems both the fuel supply and the ignition circuit are disabled. As the engine speed decreases the engine block cools faster than the pistons since the block is water cooled and this uneven cooling may result in damage when the engine is shut down at high speed. The instant invention maintains the fuel supply to the pistons after engine shut down to cool and lubricate the pistons and prevent possible engine damage.
