Question

When a timing chain or belt skips or breaks and causes collisions between pistons and valves, it is because the engine is an interference engine. In contrast, noninterference engines have enough clearance between the pistons and valves that they will not collide if the timing chain or belt fails. Freewheeling engines are those in which power is not transmitted from the engine to the transmission when the throttle is released, and production engine is a broad term that simply refers to any engine that is produced for commercial use.
