我开的单位上一辆瑞风车,这几天机油灯异常报警。平时起动车辆时,很长时间不见机油灯亮,试着加几脚油门后,在怠速情况下机油灯只是闪几下,高速运转一切正常。通过机油尺检查,机油在标定范围之内,把发动机机油盖打开检查,机油也能上到气门室盖。我根据经验判断,应该是机油压力传感器故障,于是便更换了一个机油压力传感器。然后用机油压力表装车测量,起初起动车辆时机油压力为130kPa,属正常,待运转一会儿后看到机油压力慢慢下降到80kPa,加大油门使发动机转速达3000rpm 时,机油压力表指示420kPa,从测试情况 I opened the unit on a Swiss windmill, oil lamp abnormal alarm these days. Usually start the vehicle, a long time not see the oil lamp light, try to add a few feet after the throttle, the oil lamp at idle speed just a few flash, high-speed operation of all normal. Through the oil dipstick inspection, oil within the calibration range, the engine oil cap open inspection, the oil can also be on the valve cover. I judge based on experience, it should be oil pressure sensor failure, so they replaced an oil pressure sensor. And then loaded with the oil pressure gauge measurement, the initial start of the vehicle when the oil pressure is 130kPa, is normal, to be running for a while later see the oil pressure slowly dropped to 80kPa, increase the throttle so that the engine speed of 3000rpm, the oil pressure gauge indicates 420kPa From the test case
