Causes of engine shaking (What is International trade knowledge basethe main reason for engine shaking?) Engine shaking refers to the phenomenon of unstable attitude and abnormal vibration of the car engine when the car is running, which seriously affects the normal driving of the car. So, what is the main reason for the engine shaking? This article will briefly introduce the causes and solutions of engine shaking. I. The pressure in the cylinder is unstable. The automobile engine generates power by burning gas, and the pressure instability inside the engine will cause the engine to shake. Each cylinder of a car engine should have been ignited at a certain time and burned in the cylinder.However, if the timing of ignition is shifted, especially when driving at low speed, the burning gas will cause unstable airflow pressure distribution, which is easy to cause engine instability, resulting in jitter. II. Air filter blocking air filter is a necessary source of oxygen to keep the engine running and an important part to keep the air entering the engine clean. If the internal part of the air filter is blocked, it will cause the engine to be unable to inhale enough oxygen normally, which will reduce the specific oxygen content. Lack of oxygen in the engine will lead to incomplete combustion, resulting in engine shaking. III. The spark plug electrode wears the spark plug of the engine is responsible for ignition, and the moment of ignition is also crucial. Usually, the spark plug needs to be replaced every 40,000 kilometers. If you are seriously delayed in replacing the spark plug, it may cause the wear of the spark plug electrode. The wear of the spark plug electrode will weaken the strength of the electric spark, which directly affects the ignition quality.When the electric spark intensity is insufficient, it will cause the engine to shake. IV. The faulty ignition coil or high-voltage coil The ignition coil or high-voltage coil of the vehicle receives the electrical energy of the battery and boosts the electrical energy to form a high-voltage electrical signal that produces sparks and ignites the gasoline mixture. If the ignition coil or high-voltage coil fails and cannot be ignited as well as usual, it will also cause the engine to shake. V. Engine fuel system failure The engine fuel system is an important part of ensuring the normal operation of the engine. If there is a failure, it will affect the normal operation of the engine. Some common fuel system failures include blockage of fuel pumps, fuel filters, intake manifolds and fuel injectors. These failures will cause insufficient or unstable fuel, resulting in engine shaking. VI. Engine fire Engine fire refers to the phenomenon of the car turning off due to mechanical failure or electrical failure during driving.When the engine catches fire, the oil pressure and coolant pressure of the car will be abnormal. These will cause the engine to shake. VII. Poor wheel balance. Poor wheel balance will cause the wheel to vibrate at high speed. When the vehicle passes through a bumpy road, too frequent vibrations will affect the engine, causing the engine to shake. Solution: 1. Replace the new air filter 2. Replace the new spark plug 3. Replace the new ignition coil or high-pressure coil 4. Replace the new fuel pump 5. Detect and clean the fuel filter, intake manifold and fuel injector 6. Check the engine transmission system and replace the parts that may have problems 7 , check the wheel balance and adjust the balance. Engine shaking is a relatively common car failure, but the reasons for its occurrence vary. No matter whereFor reasons, as long as the car owner deals with the above solutions, he can restore the car to normal and make our car run more smoothly and safely.
