How to Determine if There's an Intake Pipe Leak?
1 Answers
An intake pipe leak can cause symptoms such as weak engine operation, increased nitrogen oxide emissions in the exhaust, or difficulty starting the engine. Below are the symptoms that may occur when there's an intake pipe leak: 1. Weak engine operation: The air entering the engine through the crack in the intake pipe bypasses the air flow sensor. This unmeasured air dilutes the combustible mixture in the engine cylinders, leading to weak engine performance. 2. Increased nitrogen oxide emissions: Nitrogen oxides (NOx) in vehicle exhaust are formed under high-temperature, oxygen-rich conditions. An overly lean combustible mixture promotes the generation of nitrogen oxides, thereby increasing the emission of exhaust pollutants. 3. Difficulty starting the engine: During the starting process, the engine requires a higher concentration of the combustible mixture. The lean mixture caused by the intake pipe leak may result in difficulties when starting the engine.
