Why can't the Mercedes-Benz engine speed exceed 3000 rpm?

[VonPhoebe]

Mercedes-Benz engine speed cannot exceed 3000 rpm for the following reasons: Engine malfunction: Engine power is generated through the coordinated operation of the intake system, ignition system, and fuel system. If any component malfunctions, it may lead to reduced engine power, resulting in symptoms such as unresponsive throttle, vehicle vibration, and smoke from the exhaust. Dirty throttle position sensor: If the throttle position sensor is excessively dirty or has voltage imbalance, it can cause electronic throttle failure, leading to situations where the vehicle cannot accelerate even with the throttle fully depressed. Fuel system malfunction: Using low-quality gasoline may cause fuel pump burnout, catalytic converter failure, or piston issues, directly affecting engine power and potentially leading to engine stalling or inability to accelerate.
