轿车在高速公路上出现怠速不稳的现象,原地空负荷急加油,能听到进气口处有明显的回火现象,总体感觉是大负荷时故障明显。预测油路故障,针对油压系统进行快速检查。模拟故障状态,挂上前进挡,踩住制动,加大了发动机负荷,故障就容易显示。再从油压测试口接上油压表,在发动机出现加速不畅的时候测量油压,完全符合技
The car appeared idle speed instability phenomenon on the highway, the original place empty load urgent refueling, you can hear the inlet at the obvious tempering phenomenon, the overall feeling is obvious when the load is large. Predict oil circuit failure, for hydraulic system for rapid inspection. Simulation of the status of the fault, put forward gear, slam the brakes, increased engine load, the fault is easy to display. Then from the hydraulic test port connected to the hydraulic gauge, poor acceleration in the engine when measuring hydraulic pressure, in full compliance with technology
