1. Insufficient power, and there is a metal knocking sound. Obviously, due to poor fuel quality and low octane, there is a burst of combustion in high-speed driving, resulting in excessive temperature in the cylinder, poor lubrication conditions, and a small gap between the piston and the cylinder, causing the piston to burn the top and pull the cylinder.
2. With the increase of the service life of the car, some failures will inevitably occur, such as the engine knocking on the cylinder. So what is the phenomenon, cause and solution of engine knocking on the cylinder?The so-called engine knocking on the cylinder refers to the phenomenon of metal knocking when the pressure increase rate in the cylinder is too high.
3. When the cold start engine is running, if there is the sound of dry friction of metal parts outside, it is generally a sign of damage to the bearings of the generator, water pump and steering booster pump. Cold start is when the engine water temperature is low, usually the car is not started for a long time. For example, after parking at night, starting the next morning, it is usually called cold start.
4. Hello, there is a knocking sound in the engine for the following reasons: the temperature is too high to deform the piston, resulting in the knocking sound of the cylinder. The engine exploded, causing a knocking on the cylinder (the explosion sensor was damaged). The engine was ignited too early, resulting in an explosion. The gap between the piston and the cylinder is too large. The piston and pin are too tight.
5. The abnormal sound of the car engine is usually caused by problems with some parts inside the engine.These problems may involve many different parts of the engine, including pistons, connecting rods, crankshafts, rocker arms, valves, oil pumps, water pumps, oil filters and engine belts.
This can only indicate that there is something wrong with the new spark plug, which may be the new spark plug model is wrong, or the new spark plug is defective.
This phenomenon is caused by excessive piston clearance or deformation of the piston. Because the piston gap is large in the cold state, the abnormal sound of knocking the cylinder is naturally more serious; when the engine temperature rises, the piston will expand, so that the piston gap becomes smaller, and the abnormal sound of knocking the cylinder is of course reduced.
Is it because the engine does not match or the spark plug is not installed, resulting in unstable and shaking of the engine, and the lack of cylinder power and abnormal sound.[If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.
This is caused by the engine knocking on the cylinder. There are many reasons for knocking on the cylinder. Engine shock will cause knocking on the cylinder, and severe wear of the cylinder wall will also lead to knocking on the cylinder.In this case, you should go to a professional institution or 4s to find a professional technician to diagnose the cause of the fault and then repair it. Engine cylinder knocking caused by explosions is more common.
[Causes for abnormal sound caused by valve explosion] Changes in the valve gap after adjustment (unsteady locking, wear of valve rod and drive parts) or improper adjustment during maintenance; valve adjustment screw wear and skew, loose locking nut, or excessive or inconsistent valve gap; valve spring seat wear, or valve The rod and catheter are excessively worn out.
Once the foot mat of the machine ages or loosens, the vibration of the engine will make a strange sound, and the foot mat needs to be replaced. Knocking cylinder phenomenon: Due to the tilt of the piston and the change of the direction of the lateral pressure, the contact surface of the piston and the cylinder changes from the secondary thrust surface to the main thrust surface. So the engine periodically made the sound of the piston knocking on the cylinder.
1. Insufficient power, and there is a metal knocking sound. Obviously, due to poor fuel quality and low octane, there is a burst of combustion in high-speed driving, resulting in excessive temperature in the cylinder, poor lubrication conditions, and a small gap between the piston and the cylinder, causing the piston to burn the top and pull the cylinder.
2. The abnormal sound of the engine indicates that the technical state of a certain mechanism of the engine has changed. If there is a sound of metal parts rubbing outside during the operation of the cold car start engine, it is generally a manifestation of damage to the bearings of the generator, water pump and steering booster pump.
3. With the increase of the service life of the car, it is inevitable that the car will have some faults, such as the engine knocking on the cylinder.So what is the phenomenon, cause and solution of engine knocking on the cylinder? The so-called engine knocking on the cylinder refers to the phenomenon of metal knocking when the pressure increase rate in the cylinder is too high.
4. The power is insufficient, and there is a metal knocking sound. Obviously, due to the poor fuel quality and the octane number is too low, there is a burst of combustion in high-speed driving, resulting in excessive temperature in the cylinder, the deterioration of the lubrication conditions, and the small gap between the piston and the cylinder, so that the piston burns the top and pulls the cylinder. Grind the cylinder and replace a set of pistons, reinstall the test car, and the abnormal sound disappears.
