柴油机运转不规则的主要表观是:柴油饥转速不稳定,有快慢或间断、机器幌动摆头、排烟不连续,有时可见白色烟圈等。其产生原因有以下几个方面: 1 燃油供给及燃烧方面 1.1 个别缸不着火或燃烧不良造成。应检查柱塞弹簧状态,柱塞弹簧过软或柱塞弹簧断均可造成燃烧不良或不着火。 1.2 各缸喷油压力、喷油量、喷油时间不一致,应调整喷油压力至规定值;校正高压油泵,使之喷油量一致.喷油间隔合乎要求即可排除。 1.3 高压油泵齿条不灵活或调速器故障。高压油泵齿条不灵活时,可逐缸稍微拧松柱塞套简定位螺钉,
The main irregularities in the operation of diesel engines are as follows: the instability of diesel starvation speed, the speed or the intermittent movement of the crane, the smoke exhaust is not continuous, and sometimes the white smoke ring can be seen. The reasons for the following aspects: 1 fuel supply and combustion aspects 1.1 individual cylinder is not caused by fire or poor combustion. Should check the plunger spring state, the plunger spring too soft or piston spring off can cause poor combustion or no fire. 1.2 Each cylinder injection pressure, fuel injection, injection time is inconsistent, injection pressure should be adjusted to the specified value; correction of high-pressure pump, so that the same amount of fuel injection. Injection interval can be ruled out in line with requirements. 1.3 high-pressure pump rack is not flexible or governor failure. High-pressure pump rack is not flexible, the cylinder can be loosened slightly by the cylinder sleeve simple set screws,
