The difference between refrigerated trucks and other special vehicles is that the refrigerated trucks rely on the engine to drive the compressor to work, and reduce the temperature of the rear compartment to achieve the cooling effect. Therefore, before loading the goods, the goods and the inside of the vehicle must be pre-loaded. It is cold, and when loading and unloading goods, it is necessary to quickly avoid the temperature rise in the compartment, thereby increasing the workload of the engine. Owners of refrigerated trucks must clean and maintain frequently to extend the service life of refrigerated truck engines. This can be done from the following aspects:
First of all, refrigerated trucks should avoid idling for a long time and driving at high speed for a long time. Both methods increase the workload of the engine and keep the engine in working condition for a long time, which is not conducive to the maintenance of the engine. Customers and friends should remember live.
Secondly, if the engine of the refrigerated truck is in a low temperature or low speed working state for a long time, the combustible mixture cannot be fully burned when the engine is running in a low temperature or low speed state, and the insufficiently combusted mixed gas and the infiltrated trace lubricating oil are mixed in the combustion chamber. Carbon deposits are gradually formed in the relatively low temperature parts of the refrigerated vehicle engine, such as the valve, spark plug and the inner side of the throttle. The carbon deposit of the refrigerated vehicle engine is very harmful. Therefore, it is necessary to do a good job in the prevention of carbon deposits, regularly clean and maintain the engine to avoid prolonged idling; use clean fuel, etc. are good methods.
Later refrigerated trucks should use the correct labelled fuel. If low-grade fuel is used, it will not only cause poor refueling and shake the body, but also cause insufficient combustion and increased emissions. In addition to carbon dioxide, these emissions include carbon monoxide, nitrogen oxides, and larger particles.
In addition, the engine should be maintained regularly to clean up the carbon deposits, keep it in good condition, and develop the habit of turning off the engine at will. Idle speed is the engine that emits more in many working conditions. It is better to get off the truck and stand on the hot summer day than to sit in the idling truck for a long time.
