(一)柴油机功率不足1.原因(1)喷油器雾化不良、体裂、弹簧折断。(2)喷油泵柱塞或出油阀卡死(不供油)。(3)燃油压力不足。(4)燃油管接头泄漏,或燃油管破裂。(5)油泵齿条或供油拉杆卡住。(6)增压压力低。(7)气环、气缸套磨耗过甚,造成压缩压力不足。(8)燃油中有空气和水分。(9)供油提前角调整不正确。
(A) Diesel engine power shortage 1. Cause (1) injector atomization, body cracking, spring break. (2) injection pump plunger or valve stuck (not oil). (3) Insufficient fuel pressure. (4) Leakage of fuel pipe fitting, or rupture of fuel pipe. (5) pump rack or fuel rod stuck. (6) low boost pressure. (7) gas ring, cylinder liner worn too much, resulting in insufficient compression pressure. (8) There is air and moisture in the fuel. (9) fuel supply advance angle adjustment is not correct.
