What Causes Car Engine Vibration?
1 Answers
Car engine vibration causes: dirty air filter, shortened spark plug lifespan, low idle speed, and clogged fuel injectors. The car engine is the machine that provides power to the vehicle, serving as the heart of the car, affecting its power performance, fuel economy, and environmental friendliness. Dirty air filter: The air filter is designed to protect the engine and reduce wear, typically requiring replacement every 10,000 kilometers. If not replaced in time, insufficient air intake can cause low idle speed, leading to engine vibration. Solution: Replace the filter element to resolve the issue. Shortened spark plug lifespan: After exceeding 30,000 to 40,000 kilometers, the ignition efficiency of spark plugs significantly decreases. Solution: Replace all spark plugs. Low idle speed: The engine idle speed value is preset in the car's computer. When the RPM drops below a certain range, the car's computer will automatically adjust it. If the idle speed is too low and causes vibration, it indicates that it has exceeded the computer's control range. Solution: Set the idle speed within a specific range. Clogged fuel injectors: The fuel injectors in fuel-injected cars are key components for fuel injection, with a long service life that can reach hundreds of thousands of kilometers. However, due to gum deposits in gasoline, the injector nozzles can become clogged, causing inconsistent fuel injection among the injectors. This leads to uneven cylinder operation and engine vibration. Solution: Remove and clean the injectors.
