Low temperatures in winter can make diesel engine startup difficult. In this case, some of the pilots often use some incorrect methods to make the diesel engine start quickly, and illegal operation will damage the diesel engine. It is important to note that starting a diesel engine at low temperatures in winter has “six bogeysâ€:
Do not use an open flame to heat the fuel tank. Using an open flame to heat the fuel tank will not only damage the paint on the surface of the body, but also it will easily burn the plastic tubing, causing oil leakage. It will even cause explosions due to the rapid expansion of gas in the fuel tank, resulting in the destruction of the body and casualties.
Second, avoid use of open fire baking tank bottom shell with an open fire baking tank bottom shell, not only affect the life of the engine, but also easy to make oil deterioration, reduce the lubrication effect.
3. Avoid bogey when starting without cooling water If you do not add cooling water at the start, and then add the cooling water after the diesel engine starts, it will cause the temperature rise of the tank due to the sudden encounter of cold water and cause the body, cylinder head cracks.
4. Avoid adding additional oil from the air intake pipe to add oil from the air intake pipe, which will make the piston and piston ring coke to shorten the service life.
5 bogey to take off the air filter suction fire start remove the air filter fire start, will make dirty air into cylinders, valves and other moving parts, intensify the wear and tear of these components.
Sixth, avoid preheating and forcibly start the diesel engine with other power without preheating, but start with other power forcefully, which will cause dry friction or semi-dry friction between the crankshaft and the bearing shell, which easily leads to the crankshaft holding.
Then, when the temperature is low in winter, how to properly start the diesel engine? The first is to use the zero point diesel fuel with low freezing point as the fuel; the second is to use hot water to preheat the diesel oil and engine oil; the third is to use the hot water of about 70°C as the cooling water, and add the edge temperature for preheating; It is necessary to use charcoal or hot water to preheat the bottom of the tank, injectors, high-pressure tubing, and the body, and then start it again.
