What are the reasons for insufficient turbocharger pressure?

[McLucille]

Introduction to the reasons for insufficient turbocharger pressure is as follows: 1. Air filter blockage: A blocked air filter increases suction loss, resulting in insufficient turbocharging pressure. Generally, the air filter should be thoroughly cleaned after 1500-3000 hours of use. 2. Excessive oil deposits: Too much oil deposit in the internal air passage of the compressor part increases airflow resistance when passing through the passage with more oil deposits, leading to a decrease in turbocharging pressure. 3. Damaged air seal device: For externally supported turbochargers, when the air seal device on the back of the compressor is damaged, a large amount of air will leak from the back to the intermediate housing and be discharged into the atmosphere together with the exhaust gas from the turbine, which will also cause a decrease in turbocharging pressure. 4. Poor fuel combustion: Poor fuel combustion causes carbon deposits on the rotor part, or increased rotational resistance of the turbocharger due to damaged turbocharger bearings, which will also lead to a decrease in turbocharging pressure.
