FUEL PUMP FOR LARGE 2-STROKE DIESEL ENGINE

摘要

PURPOSE: A fuel pump for a large two-stroke diesel engine is provided to cut off fuel transferred to each fuel injecting valve for partial injection, and to increase injecting efficiency by raising an injection pressure. CONSTITUTION: A fuel pump for a large two-stroke diesel engine comprises multiple fuel injecting parts(100) and a controlling part. The fuel injecting part include a fuel inlet into which fuel flows, a delivery valve(120), and an air piston(130) placed on one end of the delivery valve. The delivery valve connected to the fuel inlet is capable of partially injecting the fuel, and opening or closing the transfer of the fuel. The fuel injecting parts are collinearly coupled along the outer circumferential surface of the fuel pump. The controlling part coupled to the upper end of the fuel pump adjusts fuel injection amount and the fuel injection time. The controlling part controls the actuation of the delivery valve and the air piston. The controlling part measures the angle values of the engine in order to control the fuel injection time. A manager can determine the measuring range for the angle values of the engine.
