What Are the Causes of Car Engine Vibration?
1 Answers
Engine vibration can be caused by: a dirty or clogged air filter that has not been replaced in time; broken high-voltage wires affecting ignition; spark plugs not replaced in time or low fuel pressure; dirty throttle body or clogged fuel injectors; low cylinder pressure. The causes and solutions for engine vibration are as follows: 1. Carbon deposits and oil sludge blockage: The throttle body, idle valve, and intake ports can accumulate carbon deposits and oil sludge over time, leading to restricted airflow, which affects idle stability and causes vibration. The solution is to inspect and clean these parts with a cleaning agent without removing them. 2. Clogged fuel injectors: The fuel injectors in electronic fuel injection vehicles are critical components for fuel delivery and have a long service life, often lasting hundreds of thousands of kilometers. However, deposits in gasoline can clog the injector nozzles, causing uneven fuel delivery among cylinders, leading to inconsistent engine operation and vibration. The solution is to remove and clean the injectors. 3. Abnormal water temperature: The engine operates within a specific temperature range. High water temperature can cause advanced ignition timing, altered air-fuel mixture, thinning of engine oil, and reduced lubrication. Common causes include insufficient coolant, a stuck thermostat, a non-functioning fan, or an inaccurate temperature control switch. Addressing these issues will resolve the vibration.
