Analysis of the causes of white smoke coming from the exhaust pipe when starting
1. Problems with the ventilation system:The valve. the game is incorrect; sealing performance deteriorates; the air filter is seriously clogged and the pressure reducing handle is forgotten.
2. There is a problem with the fuel supply system:If the diesel quality is not good, water has entered the diesel tank; there is air in the oil line; the low pressure oil line is blocked and the inlet throttle filter is blocked. The filter element is too dirty and the fuel tank cap vent hole is clogged, resulting in insufficient oil supply. too late.
3. Problems with the engine body:There are cracks in the cylinder head; the cylinder seal is not installed correctly oris burned out, causing water to enter directly into the cylinder; etc. ; There is a problem with the crank rod mechanism, such as the clearance of the cylinder, piston and piston ring is incorrect, seriously worn or stuck, etc. ; there is a problem with the engine starting device, such as weak cranking; speed, etc. ; the temperature is too low or the engine temperature is too low (especially in winter).
Research and troubleshooting
1. The simple idea of research and troubleshooting is to analyze and check the above reasons in turn. Generally, first check whether there is air or blockage in the low pressure oil line, check the oil transfer pump, then check the high pressure oil line and oil transfer pump. fuel injection. If there is no problem with the above inspection results, then. Check in turn the fuel injector, the ventilation system, thecrank connecting rod and engine body.
2. If the temperature is particularly low in winter or on the day the tractor is started, you can try heating the water in the water tank, or draining the oil from the oil pan, heating it and then putting it in. he comes back. If you're using a small gas engine to start the tractor, you might as well start it several times. If this doesn't solve the problem, consider other reasons.
