The current domestic heavy-duty truck engines are mostly air-to-air cold pressurization technology. The intercooler is an important component of the supercharged engine, and many people are not unfamiliar. The role of the intercooler is to allow the air passing through the supercharger to first enter the cooling process, keeping the pressurized air that enters the cylinders to maintain a stable temperature and pressure. Most of them are installed in front of the water tank radiator, and the appearance and structure also have a lot in common with the water tank.
The long-lived normal operation of the engine requires an absolutely clean intake system, but often due to various factors, the air in the intake system cannot reach the standard. For example, turbocharger helium oil, air filter failure, air intake line breakage, etc., the interior of the intercooler becomes dirty and even plugged. Severely affecting engine power and rapidly increasing fuel consumption are not alarmists. The following case may remind you.
As the driver suddenly found that fuel consumption began to increase in the past month, one by one to check all parts of the engine, focused on checking the intake system, through preliminary judgment of professional equipment intercooler may be blocked. Remove it and start the cleaning process. Pour a lot of stuff, like a flocculent mixture of cotton. Through these impurities, it was initially determined that the intercooler was essentially unrepaired.
Through the disintegration of the intercooler, a large amount of impurities appeared. So what exactly is the cause of the plugging of the intercooler? The owner's tractors are mainly based on wind power equipment transportation. They go early to the pastoral areas and plateaus, and many fall catkins pop a lot. There are also leaky air intake pipes that may not be noticed.
Check the inlet line and the supercharger again and notice that there is oil on the inlet pipe wall. The turbocharger found that the shaft was oscillating and the impeller was broken. Finally, the cause of the failure emerged completely. After replacing turbocharger, intercooler, and cleaning pipeline, the fault was thoroughly investigated. After the vehicle test, the fuel consumption and power returned to normal.
What causes the intercooler to be blocked?
Inferior air filter, turbocharger inlet part of the pipeline rupture, loose loose seals, booster body oil damage and other reasons.
Why does the supercharger suck oil? Is it quality reason?
Turbocharger oil is often caused by humans, such as:
1 The oil quality is poor, the oil change period is too long, and the oil is not processed in time after the oil enters into the diesel oil.
2 Due to driving habits, if the throttle and parking are turned off quickly in winter, the supercharger will be poorly lubricated, and the dry grinding will be scrapped.
3 The supercharger bypass valve is not working properly, and the pressure relief action cannot be completed in time, causing supercharging overload, superheater body overheating, high temperature, and wear. Intercooler pressurization overload, fracture failure.
Can the intercooler be cleaned? Is there any good way?
If the intercooler is light oil and dust pollution, it can be filled with the right amount of gasoline, fully dissolved, rinsed repeatedly with water, and it is not recommended to use acidic or alkaline liquids for lavage. The second type, if there is a large area of ​​blockage caused by the breakdown of the inferior filter and the pipeline, there is basically no repair value. The intercooler is basically a high-strength aluminum component. Even if it is welded after dismantling, it is easy to break again. It is recommended to replace the new one. Intercooler.
