Five notices of winter cold prevention for automobiles
Category:Automobile maintain - Date:2018-04-21
In the near future, the cold wave invaded most of the country, and the sudden drop of temperature has a great influence on the driving, and the automobile itself, it is particularly important to replace the antifreeze in time and check the electrical equipment, mainly including the project:
Replace all kinds of oil
(1) use low pour point fuel with good fluidity. At low temperature, the viscosity of fuel increases and the fluidity becomes worse. The combustion process of fuel is deteriorated easily, and the starting, dynamic and economical efficiency of the engine is obviously reduced. Therefore, under the condition of conditions, the fuel with low condensation point should be selected. The general choice principle is that the solidifying point of fuel is about 5 degrees below ambient temperature.
(2) change the oil. In the low temperature condition, the viscosity of engine oil increases with the temperature decreasing, and the fluidity becomes worse. Therefore, the bad oil should be replaced in time to make up or eliminate the bad effect.
(3) replace all kinds of lubricants and grease used in winter. In winter, we should use winter lubricating oil for transmission, main reducer and steering gear. Wheel bearings should be replaced with low drop grease.
Maintenance of the engine cooling system
(1) check the working condition of the thermostat, ensure that the thermostat works well and prevent the engine water temperature from being too low or too high. If the engine is often operated at low temperature, it will lead to the increase of machine wear.
(2) scavenging the scale in the water jacket. Cleaning the engine water jacket, cleaning the internal scale, preventing excessive accumulation of scale, affecting the engine heat to make the machine temperature too high, such as water scale blocking the release of water switch, will lead to not clean water.
(3) annotation of antifreeze. When the temperature is too low and the conditions are allowed, the antifreeze solution can be used to clean the cooling system thoroughly before use, and the antifreeze liquid with good quality and low corrosion should be selected to avoid the phenomenon of corrosion of the machine parts because of the quality of the antifreeze liquid.
Maintenance of electrical equipment
(1) check the density of the electrolyte. The density of electrolyte can be raised properly to prevent the accident of battery shell from cracking because of the low density of electrolyte.
(2) the charging voltage of the high power generator. Due to the increase of battery discharge at low temperature, the charge quantity of the generator must be increased, and the limit voltage of the regulator can be properly adjusted. In general, the limit voltage of the regulator in winter is more suitable than 0.6V in the summer.
(3) maintenance of the starting motor. It is difficult to start the engine in winter, and the frequency of starting motor is frequent. If the power of the starter is not enough, it will further increase the difficulty of starting the engine. The practice shows that in the summer, starting the engine may be very smooth if the engine has a slight failure and the power is slightly insufficient, but it will become very difficult to start in winter and even can not be started in winter. Therefore, a thorough maintenance of the starter should be carried out to keep the parts of the starter clean and dry, especially between the brush and commutator.
(4) to strengthen the insulation of the battery. In order to prevent freezing and affecting the startup performance of the battery, a sandwich thermal insulation battery box can be made in winter to improve the battery temperature.
adjustment of fuel system and ignition system
in winter, the oil level of the float chamber of the carburetor can be raised properly and the stroke of the oil pump should be adjusted to make the mixture suitable for low temperature operation. To facilitate low temperature startup, the closing angle of the contact should be appropriately increased, and the contact gap should be adjusted to 0. 30 to 0. 40 mm to enhance the spark intensity.
Maintenance preheating device
For the engine with the preheating device (mostly diesel engine), the preheating equipment should be checked and maintained before winter to ensure that the technical condition is good. During maintenance, the circuit and oil circuit should be inspecting emphatically to prevent the engine starting performance due to the poor working of the preheating device.
