What to Do When the Engine Delays Shutting Off After Turning Off the Key?
1 Answers
If the engine delays shutting off after turning off the key, it is recommended to check the following: 1. Carbon deposits on various components: Especially inside the cylinder, such as whether the spark plugs have excessive carbon buildup or if the combustion chamber has too much carbon. Since the engine operates at high temperatures, the carbon deposits inside the cylinder can remain hot and ignite the air-fuel mixture even after the spark plugs are deactivated (when the ignition is turned off). 2. Throttle: Check if it is not closing properly. 3. Fuel injector: Inspect whether the fuel injector is leaking. Precautions for using a car engine are as follows: 1. Avoid driving in neutral: The engine itself has a fuel-cut function during deceleration, and driving in neutral can actually reduce fuel efficiency. 2. Pay attention to observations: If oil is found on the ground, determine whether it is due to engine oil leakage and promptly communicate with the car dealership to eliminate potential safety hazards. 3. When brake fluid is contaminated with or absorbs water: Or if impurities or sediments are found in the brake fluid, it should be replaced or carefully filtered immediately. Otherwise, it may lead to insufficient braking pressure, affecting braking performance.
