An engine is typically a machine for converting thermal energy into mechanical energy or power to produce force and motion. Although, the dictionary also states that an engine can be a motor, but generally only in smaller sizes, such as those in an automobile. The engine on a ship would never be called a motor. Electrically, a motor is not an engine, but an engine can be referred to as a motor, if the size fits. So there, call that thing under the hood what you want, but don't call an electric motor an engine. /ubbthreads/images/graemlins/thirsty.gif
