How to maintain the engine in winter？
At the beginning of the winter, I believe that many owners have encountered these situations, such as the engine can not start, the engine is turned off when shifting. So how does motivation prevent these problems from appearing?
The engine cold start is difficult, the main reason is that the engine temperature is too low, so we only need to keep the engine warm, not let the biting cold wind directly into the engine compartment, you can avoid the car. Therefore, pay attention to the direction of the front of the car when parking in winter. It is best to let the front of the car face the building and use the building to block the wind to prevent the engine from being cold and cold. When parking at night, you can put the front of the car in the direction of the sun, so that the first sun in the morning can shine on the front of the car and help the engine warm up, so it is much easier to get out. Usually, we must regularly check the service station to check and adjust. 3. When the gear is changed, the engine is turned off.
When the engine is turned off during shifting, it may be because the idle speed is too low at the time, or the idle stop valve is not tightened, or the gear may be too high, and there may be a serious blockage of the oil separator. Usually, the first step is to apply a file. Check the idle stop valve to see if it is tightened and the plug is tight. At the same time, it is best to go to the designated service station to clean the oil separator.
In addition, the fuel system fuel should be cleaned regularly. In the process of burning through the oil circuit to the combustion chamber, gelatinous and carbon deposits are inevitably formed, which are deposited in the oil passage, carburetor, fuel injector and combustion chamber, interfere with fuel flow, destroy normal air-fuel ratio, and make fuel Poor atomization, causing engine surge, explosion, idle speed, poor acceleration and other failures. Use the BG208 fuel system to clean the fuel system with a powerful and highly efficient cleaning agent to control the formation of carbon deposits and keep the engine in top condition at all times.
The use of oil of the appropriate quality grade is also important for the maintenance of gasoline engines. SD-SF grade gasoline engine oil should be selected according to the working principle and working conditions of the inlet and exhaust systems. For diesel engines, CB-CD grade diesel engine oil is selected according to the mechanical load. Regardless of the gasoline engine or diesel engine, the selection criteria are based on the requirements specified by the manufacturer.
Regular oil and oil filter cartridges are also important processes for daily maintenance of the engine. The oil quality will change during the use of any quality grade of oil. After reaching a certain mileage, the parts will wear out, causing failures in the engine and degrading performance. In order to avoid the occurrence of faults, the oil should be replaced regularly with the mileage, and the oil volume should be moderate (usually just below the upper limit of the oil scale). As the oil passes through the pores of the filter, solid particles and viscous material in the oil can accumulate in the filter. If the filter is clogged and the oil cannot pass through the filter element, it will swell the filter element or open the safety valve. Passing through the bypass valve will still bring the dirt back to the lubrication part, which will aggravate the engine wear. Therefore, the oil filter element should be cleaned or replaced regularly.
