The heart is one of the most important organs in the human viscera, and needs to be well protected in daily life; As the engine of the "heart of the truck", it provides continuous power for the truck, and it also needs the careful daily maintenance of truck friends.
The first step of maintenance: choose the right fuel
▲ Select diesel oil with a grade at least 6 ℃ lower than the ambient temperature. Because the cloud point of diesel fuel is 6 ℃ higher than the freezing point, paraffin crystals will appear at minus 29 ℃ for - 35 # diesel fuel. At this time, paraffin crystals will block the filter element, resulting in vehicle weakness and other phenomena. Therefore, when selecting diesel fuel, attention should be paid to the cloud point of diesel fuel.
▲ Pay attention to the cleanliness of fuel. Particulate suspended solids and floating water in the fuel will directly affect the performance and life of the diesel engine fuel system.
▲ Select the liquid that is transparent, free of particulate suspended matter and floating water, and free of peculiar smell and high-quality vehicle diesel.
▲ In order to prevent the influence of water on the engine, it is necessary to drain the water in the fuel system regularly.
The second step of maintenance: control the engine temperature
▲ Many truckers think that overheating of the engine will cause harm to them, but in fact, low temperature is also harmful to the engine.
▲ If the thermostat is removed blindly due to high engine temperature, the engine will often work at low temperature, resulting in reduced engine power, accelerated wear and increased fuel consumption.
▲ The engine shall be driven according to the normal temperature specified in the truck operation manual to ensure that the engine will not be damaged in advance.
The third step of maintenance: replace the air filter element
▲ The intake system of truck engine is mainly composed of air filter element and intake pipe. The air filter element should be replaced after three times of cleaning. The cleaning cycle can be determined by the air quality in the daily driving area.
▲ So it is better to buy the original air filter provided by the manufacturer, and the quality will be guaranteed.
The fourth step of maintenance: there are methods for selecting the coolant in the truck radiator
▲ Rust, scaling and corrosion are the most common problems in the cooling system. These problems are often caused by the lack of good radiator coolant - antifreeze. Many truckers usually add ordinary water to the truck radiator.
▲ Good antifreeze not only has a low freezing point, but also has other functional additives, which have the effects of inhibiting foam, rust prevention, electrolysis prevention, and scale prevention. Therefore, it reminds card users to carefully choose the coolant that is beneficial to the truck radiator.
