What Are the Reasons for Strong Exhaust Smell Inside the Car?

[VanTucker]

There are several main reasons for a strong exhaust smell inside the car: 1. The car hasn't warmed up yet, and the smell will dissipate after warming up; 2. Incomplete combustion due to improper air-fuel mixture; 3. Carbon buildup or erosion on the spark plugs; 4. Leakage in the ignition wires; 5. Malfunctioning oxygen sensor, insufficient intake system pressure, or inadequate air intake. Methods to address the strong exhaust smell inside the car: 1. First, clean the carbon deposits. If the smell persists after cleaning, the vehicle should be inspected and repaired; 2. Open the car doors to eliminate odors inside the car. Regularly open the windows and doors to facilitate air exchange between the interior and exterior, allowing harmful gases inside the car to evaporate as quickly as possible.
