For our heavy truck industry, we are about to enter the most difficult season of the year - winter.Today, the attentive service guard will check the precautions for heavy truck use in winter, so as to help you to use cars in winter without worries and make big money happily and safely!
Winter fluid change
Check whether the antifreeze label, engine oil model and glass cleaning solution meet the local ambient temperature. If not, it is recommended that the user change the antifreeze, engine oil and glass cleaning solution to meet the local ambient temperature in time. Do not buy the products from irregular channels for the sake of low price. It's not worth it!
Heating system use
If there is snow or ice on the windshield, do not start the wiper forcibly. If there is enough time, turn on the heating system to blow the ice or snow before driving. In a hurry, you can choose to use a glass frost shovel or a small card to scrape the snow or ice toward the single direction of the glass. Do not choose sharp objects to avoid damage to the glass. Before parking for a long time, you can Set up the wipers.
In winter, keep the independent heating oil circuit full of low-grade fuel, and use the independent heating to work for more than 40 minutes to complete the complete combustion of fuel in the pipeline.
Battery use and maintenance
Check the electrode pile head of the battery to ensure that it is firmly connected, clean the dirt on the positive and negative pole pile heads regularly, supplement the electrolyte if necessary, park the battery in the low temperature environment for a long time, and remove the battery and place it in the warm room to effectively alleviate the performance degradation.
Precautions for starting and stopping
When starting, the original geothermal vehicle will run at a low speed for a period of time after the speed is stable, and it can run normally after the lubricating oil is fully lubricated.Idle for 3 minutes before stopping. After turning off the key, wait for 90 seconds before turning off the main gate.
Use of LNG heavy truck
When filling each time, ensure that the filling port is clean to prevent water and dirt from entering the cylinder and causing pipeline blockage. After filling, fasten the dust cover of the filling seat and the gas return seat.
When the vehicle is started, it is required to idle for 3 minutes, and run the vehicle again when the water temperature reaches 40 ℃, so that the vehicle is completely warmed up. After starting, it is forbidden to operate the cold engine with large throttle, and gradually increase the engine speed after cold starting;
Before driving, open the liquid outlet valve (clockwise is closed, counterclockwise is open). When opening, please operate slowly. If the opening speed is too fast, it may cause the overflow valve to close automatically, and the gas cylinder will not be able to supply air. After the valves are fully opened, rotate clockwise for half a circle;
If the pipeline or valve is frozen, don't hit it with a hammer. You only need to use clean water (tap water) at room temperature to pour water into the frozen place without pressure, and the ice can melt.
The filter element must be cleaned or replaced in time to avoid the filter element being too dirty and blocking the pipeline;
When the vehicle is parked overnight, the booster valve, liquid outlet valve and vent valve shall be closed, and the vehicle shall be started until the automatic flameout, so as to avoid the ice blockage of the pipeline due to the low temperature at night.
