What is the situation of a misfiring cylinder due to fuel injector issues?
1 Answers
Fuel injector misfiring causes are as follows: Fuel injector clogging: After prolonged use, fuel injectors may become clogged. Firstly, long-term carbon buildup accumulation can lead to blockage of an injector, resulting in misfiring symptoms. Secondly, fuel injectors subjected to prolonged high-pressure gasoline flow will gradually age and develop a series of issues, such as nozzle deformation and solenoid valve switch delay. Excessive fuel injection will cause an overly rich air-fuel mixture, leading to backfiring, shaking, and other fault phenomena. If one fuel injector is clogged, it may also cause "misfiring" resulting in intermittent engine shaking. Spark plug failure: As is well known, spark plugs are consumable automotive components with limited service life. For instance, standard copper-core spark plugs have a lifespan of 30,000 kilometers, platinum spark plugs can last up to 80,000 kilometers, and iridium spark plugs may reach 100,000 kilometers with proper usage. However, even if spark plugs haven't reached their lifespan limit, failures causing misfiring can occur. One major culprit is carbon deposits. Spark plug carbon buildup is reversible, and performance can be restored through cleaning.
