喷油泵是柴油机燃料供给系中最重要的组成部分,它的性能和状态的好坏,对柴油机的工作有着十分重大的影响,因此,人们常把喷油泵称作柴油机的心脏。柴油通过喷油泵增压后,经高压油管泵到喷油咀,并能随着柴油机工作负荷和转速的变化,定时、定量并且均匀地供给柴油机各个气缸燃烧所 Fuel injection pump is the most important part of the diesel fuel supply system, its performance and status of the good or bad on the work of diesel engines have a very significant impact, therefore, people often put the fuel pump is called the heart of the diesel engine. Diesel fuel pump pressurized, the high-pressure tubing to the nozzle, and with the diesel engine load and speed changes, timing, quantitative and uniform supply of diesel engine combustion of each cylinder
