How to Determine if the Intake Pipe is Leaking?

[DelAthena]

Methods to determine if the intake pipe is leaking are as follows: 1. Engine runs weakly: Since the air sucked into the engine from the intake pipe crack does not pass through the air flow sensor, this part of the gas will dilute the combustible mixture in the engine cylinder, leading to symptoms of weak engine operation. 2. Increased nitrogen oxide emissions in exhaust: Since nitrogen oxides (NOx) in vehicle exhaust are generated in a high-temperature, oxygen-rich environment, an overly lean combustible mixture will further promote the generation of nitrogen oxides, thereby increasing the emission of vehicle exhaust pollutants. 3. Difficulty starting: Since the engine requires a higher concentration of combustible mixture during the starting process, the lean combustible mixture caused by intake pipe leakage may lead to phenomena such as difficulty starting the engine.
