1) check Baotou beiben accessories spark plug ignition system, when the engine is idling, with a wooden handle or a screwdriver tip on the metal shell cylinder cover or the engine itself, and the metal part of driver contact with each spark plug thread, such as engine and by RIT down, the spark plug in the normal state, if there is no change in engine speed, the spark plug is compressed or failure of the engine itself is not ideal. To see the state of the spark plug, the spark plug in the combustion chamber is oil or coke.
2 points of the high-voltage coil has the disadvantages – such as spark plugs intact, and the engine is still a flameout phenomenon, it may be the power point dent or ablation caused by excessive. The dent is too large to indicate that the distributor is out of service.
3) failure of oil supply system
4) Baotou North heavy duty truck parts valve or valve clearance adjustment inappropriate
A) in turn or improper carburetor adjustment, high-speed operation, engine speed is not slow or uneven, and tempering after running for a long time
B (gasoline) is not completely burned, the engine running in uneven running, and in the acceleration can not be turned quickly, this difficulty is not complete combustion. Lubricant for lubricating the cylinder wall and the crankshaft without evaporating or or completely burning gasoline. (such as the sound produced in the engine, is likely to be difficult to operate, blocking the piston, when running at high speed by the intake manifold injection cylinder oil, the amount of wash oil. The piston ring and cylinder damage): start the engine and the speed is slightly higher than the idling speed, then the ventilation tube, listen, if there is a slight hissing, indicating the cylinder pressure into the crankcase, where there is a rich spark plug, said piston ring and cylinder wall damage phenomenon has occurred. Maintenance methods: if it is excessive damage, should be re honing cylinder.
5 valve leakage: valve leakage is caused by engine flameout or one of the reasons for the uneven speed. To test whether the intake valve leakage can be placed on the carburetor carburetor inlet, if the gas leakage from the air valve blowing back, the handkerchief was blown open. Baotou North Heavy Duty Truck Parts exhaust valve leakage can be heard on the exhaust pipe, such as hiss issued, indicating that the exhaust valve leakage. Method of repair: re polish the exhaust valve to make the gap moderately.
