Diesel engines are mainly used for the final products, such as high power high speed diesel engine main heavy-duty truck, buses, engineering machinery, ships, generators, etc. Therefore, the development of diesel engine industry depends largely on related end products market situation. Winter low temperature start pay attention to the "six to prevent" diesel engine.

        In the field of agricultural diesel engine, market growth of developing countries drop will make up for the markets of developed countries, the rapid growth of the global population, and the upgrading of old equipment all have a great demand for agricultural machinery, agricultural diesel engine markets around the world will be rapid growth.
        Low winter temperatures, can bring difficulties to diesel engine start. In this case, some people make the diesel engine start quickly, often with some incorrect method, illegal operation, damage to the diesel engine. So winter low temperature start pay attention to the "six to prevent" diesel engine.
        A, prevent using flame heating and baking oil sump tank. With flame heating tank, will not only damage the paint on the surface of the body, and easy to burn out the plastic tubing, caused the spill, even for the tank of gas explosion and explosion, lead to the destruction of the body, and casualties, With flame roasting pan, affect the service life of the engine, and easy to make oil deterioration, reduce the lubrication effect.
        Second, prevent the startup without cooling water. Some drivers are able to quickly start the diesel engine, often using anhydrous start abnormal start method. And after waiting for diesel engine start to add cooling water, can make the temperature of the water tank body, cylinder head caused by the sudden encounter cold water to produce crack.
        Third, add add oil to prevent from the inlet pipe. From the air inlet pipe, add oil, can make the piston and piston ring carbon deposit, reduce the service life.
        Fourth, to prevent the flame combustion starting. Can't take the air filter, dip in with cotton on diesel light into kindling in inlet pipe on combustion startup. So that in the process of start, outside dust will directly without filtering inhaled air cylinders, causing the abnormal wear of the piston and cylinder parts, also can cause rough diesel engine work, damage to the machine.

        Fifth, to prevent forced start without preheating. Diesel engine without preheating, and in other power to start, can make between crankshaft and bearing in dry friction or half dry friction condition, it is easy to lead to the crankshaft watts.
        Six, prevent premature water or cooling water. Before stall in idle running, wait for cooling water temperature dropped to below 60 ℃, water is not hot, remove water again. If early to put off the cooling water, the body in the cold air suddenly hit the higher temperature will produce snap-back, appear crack. Residual water in the water when the body should be thoroughly, in order to avoid the freezing expansion, to make the body burst.

        So, when the winter cold, should how to properly start the engine? One is to choose the number "0" with low solidifying point diesel oil as fuel. The second is to preheat diesel with hot water and oil; Three is to add about 70 ℃ hot water as cooling water, temperature and adding while put.; Four is to use charcoal fire or hot water heating oil respectively the bottom of the shell and nozzle, high pressure oil pipe, and the body, and then start again.
