What does poor combustion ignition in cylinder n degree 2 mean?
2 Answers
Poor combustion ignition in cylinder n degree 2 means the spark plug gap is inappropriate. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high voltage into the combustion chamber and generates a spark by jumping across the electrode gap, thereby igniting the combustible mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. Below is an introduction to spark plugs: Function of spark plugs: The function of a spark plug is to introduce the pulsed high voltage generated by the ignition coil into the combustion chamber, using the electric spark produced by the electrodes to ignite the air-fuel mixture, completing combustion. Classification of spark plugs: Commonly used spark plugs are categorized into resistor spark plugs, platinum spark plugs, and iridium spark plugs. Generally, resistor spark plugs have a lifespan of 20,000 kilometers, platinum spark plugs last up to 40,000 kilometers, while iridium spark plugs can last between 60,000 to 80,000 kilometers.
Hey, I used to wonder about this when I was first learning to drive. A misfire in cylinder #2 means the ignition in the second cylinder of the engine is unstable—the spark plug might be firing weakly or not at all, leading to incomplete combustion of the air-fuel mixture. Think of the engine like a band, with each cylinder responsible for a beat. If cylinder #2 falls behind, the whole car shakes noticeably, struggles to accelerate, and feels like the engine is coughing intermittently. This is often caused by carbon buildup on the spark plug, a worn-out ignition coil, or low cylinder pressure affecting compression efficiency. I’d recommend getting it checked ASAP—delaying could waste fuel, cause excessive emissions, and even lead to engine overheating or damage. Regularly replacing spark plugs can prevent bigger issues down the road.
