The engine of a refrigerated truck is a key component of refrigerated trucks to maintain power and temperature. Under normal circumstances, refrigerated trucks are all equipped with supercharged engines. How do you maintain the engine?
First of all, the engine oil of refrigerated trucks must use high-quality engine oils that are resistant to high temperatures and oxidation resistance, and the oil replacement cycle should be appropriately shortened. The correct start-up flameout process for a turbocharged engine should be: In the first few minutes after starting the refrigerated truck, it should be idle for a few minutes. After waiting for the oil to reach its best condition, the engine can be operated at high speed after the accelerator pedal is pressed, especially in the winter. After the refrigerated truck starts, it must pay attention to let the car warm up first. The parking is very easy to ignore because of the high temperature of the turbine, so it is better to park the engine at idle speed for a while before turning off the engine. The engine's oil system and cooling system are still working. The temperature of the turbine can be slowly lowered. It should be noted that after the vehicle is extinguished, the turbine will continue to operate due to inertia. At this time, the oil is still required to be lubricated. If the engine is suddenly turned off at this time, the entire engine system will no longer work. The turbine cooling system and lubrication The oil supply will also stop immediately and only rely on natural cooling, which will lead to a sharp drop in turbine life.
Then it is necessary to regularly check the appearance of the turbocharger to see if there is any damage to the seal rings, whether there are signs of looseness and oil leakage in the oil inlet pipe and the return pipe joint, whether there is residual organic oil in the exhaust port of the turbocharger, and the compressor Whether there is abnormal sound or abnormal vibration in the straight pipe wall, whether there is organic oil and turbocharger.
Finally, we must pay attention to keep the refrigerated truck turbine clean, because the gap between the turbocharger shaft and the sleeve is very small, if the use of oil is not clean or due to impurities in the oil filter is not clean, it will cause Excessive wear of the turbocharger, if the intake air contains a lot of impurities, once the dust particles enter the turbocharger impeller running at high speed, the dust particles will make the dust particles hit the turbocharger impeller, resulting in instability of the turbine operation, bushing And the seal wears, so refrigerated vehicles with turbocharged engines must pay special attention to the timely replacement of oil filters and air filters to keep the turbine clean.
