There is no burst sound or intermittent burst sound from the cylinder, and the exhaust pipe emits white smoke. The starting speed is normal, but cannot catch fire. It should be checked on the starting circuit to determine whether the battery has sufficient electricity, whether the wires are tightened well and whether the starter motor works well, and whether the air filter element is blocked. For the diesel generator cannot start or start difficulty of this failure, it is usually judged and checked based on several different faults.įor diesel engines that use electric starting, if the starting speed is very slow, most of these faults are that the starting motor is weak, which does not mean that the diesel engine itself has a fault. The failure should be carefully observed before inspection. The injection time is too early (it is easy to kill the injection pump) or too late b. The intake and exhaust valves are not closed tightly. The piston ring is broken or the elastic force is too small c. The clearance between the piston and cylinder wall is too large b. The air filter element is blocked or dirty.Ĭylinder compression is not good a. The fuel injection nozzle is poorly sprayed or does not spray fuel e. When the diesel engine is started, the ambient temperature is too low c. There is no diesel oil in the fuel tank, the oil pipeline is blocked, the fuel filter element is blocked, and oil switch is not open b. Improper adjustment after pressure reducing device is not put into the correct position c. From the above prerequisites for starting a diesel generator, it can be inferred that the diesel generator cannot start or is not easy to start.ĭiesel engine speed is low a. The oil and gas circuits must be unobstructed C. Practice has proved that in order to maintain the smooth start of diesel generators, four necessary conditions must be met: a. No explosion sound in the cylinder, white smoke from the exhaust pipe Diesel generator start-up failure or difficult to startĪ.
