What is the normal value of engine intake flow?
1 Answers
Most vehicles have an intake flow rate between 1000-1500g/s. Intake flow in different gears: This cannot be precisely determined as intake volume varies with engine displacement. The specific value depends on which gear is engaged, as different gears have different intake volumes. To determine normal intake flow, calculate based on your vehicle's displacement. Generally, an intake flow of 1000-1500g/s is considered normal for most vehicles. Intake volume: Intake volume refers to the flow rate of fresh air entering the car engine, which provides the necessary oxygen for proper engine operation. Accurate estimation of cylinder intake volume under transient conditions is one of the effective measures to improve the precision of engine air-fuel ratio control.
