有一种采用电磁阀来进行喷油量调节和定时的新型喷油泵,它可用于轿车和公路、越野中型货车的直喷或非直喷柴油机。博世(Bosch)公司工程师声称,促使研制这种新型喷油泵的主要原因是目前对降低柴油机排放、改善燃油经济性和驾驶性能日益增长的要求。它们要求高精度的喷油系统、与发动机良好匹配并对发动机控制的灵活性。 There is a new type of fuel injection pump with solenoid valve for fuel quantity adjustment and timing, which can be used for direct injection or non-direct injection diesel engines of cars and road, off-road medium goods vehicles. Engineers at Bosch claim that the main reason for the development of this new fuel injection pump is the current need to reduce diesel emissions, improve fuel economy and improve drivability. They require high precision fuel injection systems, good engine compatibility and engine control flexibility.
