Unit Type: 250-450GF; rated power: 250-450KW; Starting mode: electric start; Speed ??mode: electronic governor; Diesel Model: HD6D51; Cooling: closed water cooling; voltage 400V; Power factor: 0.8T; NW : 7500KG check the gas engine ignition timing, check the first cylinder valve timing is consistent with the technical requirements; use the gun to measure the engine timing the actual ignition angle is equal to the theoretical ignition angle. Check engine valve clearance is within the scope of the technical requirements, check the spark plug gap is within the scope of the technical requirements; check the camshaft and crankshaft sensor signal plate and the air gap; check the signal plate for loose or abnormal rotation phenomena; measuring signal the air gap between the plate and the sensor directions. Check the engine wiring harness and vehicle wiring harness, speed sensor harness for wear, breakage and other anomalies Inspect the exhaust system blockage and other phenomena; in particular, whether the catalytic converter sintering blockage Check gas pipeline is clogged; in particular, the gas pipeline The high and low pressure filter; whether high and low pressure solenoid valves and other components work properly. As these measures can not solve the problem, test each cylinder compression pressure. Shandong gas engine | Weifang Huadong (certified) | gas engine provided by Weifang Huadong Engine Co., Ltd.
