What is the situation when the boost pressure of Mercedes-Benz C180 deviates from the standard value?
1 Answers
Mercedes-Benz C180 boost pressure deviation from the standard value is a comprehensive fault, with the main cause being the decrease in turbocharger rotor speed. The following are detailed reasons: 1. Speed: Generally, when the engine operates at the rated speed (above 2500 rpm), the turbocharger rotor speed reaches as high as 150,000 to 200,000 rpm, allowing the boost pressure to reach the rated value. 2. Bearing damage: When the bearing and shaft wear out, the turbine or pump wheel blades deform or get damaged, or when the rotor rubs against the housing, causing the rotor speed to decrease, the boost pressure will consequently drop.
