This Nissan engine also borrows the Nissan M engine's short-skirt piston design to reduce overall engine height for a lower center of gravity and better weight balance. This reduces the risk of oil cavitation, improving engine durability. The SU type (Surface-Up type) piston skirts used on previous Nissan engines like Nissan M12A Engine were also adopted for the Nissan K21 to improve oil control at high speeds where the pistons are moving faster than the crankshaft speed. This Nissan forklift engine uses nitride-treated rocker arms and camshafts to increase strength and reduce wear. This Nissan engine is also one of Nissan's first engines to use an all-aluminum construction cylinder head (most Nissan engines still used cast-iron heads until late 2005). The K21 engine utilizes a die-cast aluminum lower block with thin-wall casting to achieve its compact size, achieving Nissan's goal of low emissions Nissan claims this engine has thermal emissions up to 40 percent lower than the Nissan M engine. This engine uses two chain-driven camshafts to operate its 24 valves it also has Nissan's VVEL (Variable Valve Event & Lift) lift and timing mechanism for both intake and exhaust valves which continuously changes the valve duration and lift height according to engine load, resulting in better performance and reduced emissions over its predecessor Nissan M engines, but without sacrificing smoothness or refinement. As the Nissan K engine, the K21 Engine is a modern, aluminum alloy engine with computerized fuel injection and Nissan's direct ignition system. It was introduced in 2001 by Nissan Bluebird Sylphy ( A32 ). The Nissan K21 is an inline-four piston engine. Why choose Lift Parts Warehouse to buy a Nissan K21 Engine?
