What is the air intake volume in kilograms per hour for the Mercedes-Benz 272 engine?
1 Answers
The idle air flow rate of the Mercedes-Benz 272 engine should be around 2.5g/s. Normal idle flow rate: Under normal conditions, the air flow signal data of the Mercedes-Benz 272 engine at idle is approximately 2.5g/s. If it is less than 2.0g/s, it indicates an air leak in the intake system. If it exceeds 4.0g/s, it suggests additional load on the engine. The normal air flow value varies for each engine model, with larger displacement engines having higher air flow values. Flow sensor fault classification: If the air intake volume increases, the ECU controls the intake volume, and vice versa. Faults in the air flow sensor are divided into two categories. One is when the signal exceeds the specified range, indicating a fault in the air flow sensor. Modern electronically controlled vehicles have a fail-safe function.
