Small bubbles appear on the edge of the Perkins 8-cylinder diesel assembly head gasket
First, the fault phenomenon.
A Perkins 8-cylinder diesel engine assembly in operation recently noticed small bubbles on the edge of the head gasket.
2. Failure analysis.
1.During the operation of the diesel engine assembly, the cylinder head gasket is an important sealing component, and its main role is to seal the cylinder and prevent water leakage. If the cylinder gasket is damaged or deteriorated, it will lead to a decrease in sealing performance and the appearance of small bubbles.
2.During the operation of the diesel engine assembly, the water temperature is also an important factor affecting the cylinder head gasket. If the water temperature is too high, it will cause the cylinder head gasket to age at an accelerated pace, resulting in the appearance of small bubbles.
3.During the operation of the diesel engine assembly, the engine oil is also an important factor affecting the cylinder head gasket. If the oil quality is not good or it has been used for too long, it will cause the oil pressure to be too low, which will affect the sealing performance of the cylinder gasket and cause small bubbles.
4.During the operation of the diesel engine assembly, improper operation is also one of the reasons for the damage of the cylinder gasket. For example, when starting or shutting down the engine, not operating according to the regulations, or accelerating or decelerating sharply while driving, etc., can cause damage to the cylinder head gasket and cause small bubbles to appear.
3. Troubleshooting.
1.Inspect the head gasket for damage or age. If it is damaged or deteriorated, it needs to be replaced with a new cylinder head gasket.
2.Check if the water temperature is too high. If the water temperature is too high, you need to check that the cooling system is working properly and cool the engine.
3.Check the oil quality and the time of use. If the oil is not of good quality or has been used for too long, it needs to be replaced with a new one.
4.Check if the operation is done properly. When starting or shutting down the engine, follow the regulations;During driving, it is necessary to maintain a constant speed and avoid operations such as rapid acceleration or deceleration.
Fourth, maintenance precautions.
1.When replacing the cylinder head gasket, make sure that the cylinder head gasket is installed correctly, flat, and tightened according to the specified requirements.
2.During the repair process, it is necessary to avoid dropping foreign objects inside the cylinder to avoid damage to the engine.
3.During the repair process, it is necessary to keep the engine clean and dry so as not to affect the performance and service life of the engine.
