我单位有台6130发动机，起动困难，或起动起来就自行熄火。经检查，原来是由于输油压力太低、喷油泵盖上回油阀磨损所致。发现此情况应先检查输油压力，低压油路压力如下降到0．2～0．4MPa／cm2时，先从燃油滤清器开始检查清洗，清洗后畅通管路，如输油压力仍然偏低，再检查输 My unit has a 6130 engine, start difficult, or start up on their own flameout. After inspection, the original is due to the oil pressure is too low, the pump cover oil return valve wear and tear caused. Found that this situation should first check the oil pressure, low pressure oil pressure drops to 0.2 ~ 0.4MPa / cm2, the first start to check the fuel filter cleaning, cleaning and smooth pipeline, such as oil pressure is still partial Low, check again lose
