Five steps to troubleshoot the lack of power caused by supercharger failure

As the core component of an engine, a supercharger provides efficient power support for the engine. For various reasons, when the supercharger fails, the truck will experience a lack of power.

Common phenomenon of insufficient engine power

● Insufficient power of the new engine just bought, most of this situation is not a fault, but caused by the initial configuration of the engine 

● Insufficient power is found after a period of use when acceleration or load changes

Analysis of the reasons for lack of power

Insufficient vehicle power is a comprehensive problem, which is affected by the system configuration and actual operating conditions of the entire vehicle, and is closely related to the engine oil supply system, electronic control system, air intake system, etc.; if there is insufficient power, it should be checked according to the engine manual cause of issue.

● Turbocharger troubleshooting steps

1. Check the external parts of the supercharger for damage, and replace the supercharger if damaged.

2. Check the supercharger impeller for damage and  impurities. If there is damage, please replace the supercharger and also check the air intake system for impurities.

3. Check whether the supercharger rubs the shell and whether the clearance of the supercharger is qualified, if it is not qualified, please replace the supercharger.

4. Turn the impeller to check whether there is obvious stalling, if there is obvious stalling, please replace the supercharger.

5. Check whether the supercharger regulator is damaged, deformed or artificially modified. If so, please replace the supercharger.

● If no supercharger problem is found in the above inspection, the lack of engine power is not caused by the supercharger, and you should continue to check other parts of the engine:

- Whether there is air leakage or air intake obstruction in the intake and exhaust system

- Whether the fuel system and parts are faulty

- Whether the vehicle transmission system is faulty

- Whether there is a problem with the criteria for diagnosing lack of power

The problem of insufficient driving power of the vehicle involves the entire vehicle system. There are many reasons. It is necessary to investigate and detect the cause of the vehicle failure in a targeted manner to avoid erroneous diagnosis.

The use and maintenance of the supercharger is as important as the use and maintenance of the vehicle, so it is necessary to take more care when using it and develop good car maintenance habits.
