有2台安装在后驱动多功能拖拉机上的S1110型柴油机,在工作中出现相同的故障:在平路或上坡时工作正常,但每次下坡后,柴油机就会熄火。检查发现油路中有空气,排净空气后,情况依旧。油路中有空气,多数是油管连接处或油管本身漏气,但这两例故障中柴油机的油路并没有漏气现象,排除了这种可能。 There are 2 S1110 diesel engines installed on a rear-drive multi-purpose tractor, with the same failure at work: working properly on level roads or uphill, but the diesel engine stalls after each downhill. Check the oil in the air, clean the air, the situation remains as before. There is air in the oil passage, most of them are leaking air at the connecting point of the oil pipe or the oil pipe itself. However, the diesel oil passage in these two cases did not leak and ruled out the possibility.
