How Long After the Engine Water Temperature Reaches 100 Degrees Will Cylinder Scoring Occur?
1 Answers
After the engine water temperature reaches 100 degrees, cylinder scoring can occur after driving 1-2 kilometers. Below are specific details about engine cylinder scoring: 1. Causes: Engine cylinder scoring refers to the appearance of obvious longitudinal mechanical scratches and abrasions on the inner wall of the cylinder within the movement range of the piston rings. In severe cases, adhesive wear can occur, leading to difficulties in starting the engine or causing it to stall. The root cause of cylinder scoring is the inability to form an oil film between the cylinder wall and the piston rings or pistons, resulting in poor lubrication or even dry friction. 2. Prevention: The engine must be properly run-in. Correctly select the clearance between the piston skirt and the cylinder liner, as well as the end gap and side clearance of the piston rings. Maintain the cooling water temperature within the normal range of 70°C to 95°C to avoid engine overheating. Avoid overloading the engine, do not start the engine without sufficient coolant, and strengthen the maintenance of the air filter to prevent dust from being sucked into the cylinder.
