Abstract: A system for starting an engine of a vehicle has a fuel injector injecting fuel into a closed intake port to form an air fuel mixture. The system also includes an actuator rotating a crankshaft in a first direction to open the intake port by moving a piston within a cylinder coupled to the crankshaft. A combustion chamber defines between the cylinder and the port receiving the air fuel mixture through the intake port. The actuator rotates the crankshaft in a second direction to close the intake port. A spark plug ignites the air fuel mixture to start the engine. The engine also includes many other disclosed features.

Abstract: A system and method selectively reduce power of an engine (14) having at least one piston (16) movable in a cylinder (18) and an exhaust port (28) includes providing an exhaust valve (32) in communication with the exhaust port (28) of the engine. The exhaust valve (32) has an adjustable position to change an effective size of the exhaust port (28). The system and method also include sensing a condition likely to cause damage to the piston (16) of the engine and adjusting a position of the exhaust valve (32) to reduce a size of the exhaust port (28) in response to sensing the condition likely to cause damage to the piston of the engine, thereby limiting power of the engine (14).
