When starting the machine operation; it is necessary to adhere to the normal oil pressure. If the oil pressure is too low; the conflicting surfaces will be accelerated due to the smoothness of the unsatisfied, if the oil pressure is too high; the oil seal and the oil pipe are simply crushed; Power. When the car is moving; the pressure of the smooth oil is usually maintained at 0. 2-0. 5mpa. When the engine is idle, the oil pressure should not be lower than 0.1mpa.
1. The oil pressure is too low; it will damage the smooth condition of the initiator; it will form smooth, cool and hygienic; it will cause the parts to wear and wear. The gap between the crankshaft main journal and the connecting rod journal and the bearing is too large; the oil viscosity is too low and If the filter breaks, the oil pressure will be too low.
2, the oil pressure is too high; although rare; but it will also damage the normal smooth conditions. If the viscosity of the oil is too large, smashing the glue; the filter element and the oil passage are blocked; if the pressure regulating valve is not properly adjusted or can not be opened, oil pressure will be formed. Too high.
3, the engine oil consumption is too much; the normal engine oil consumption and the share of gasoline is 0. 5% -1%; if it is greater than 1%, it is not normal. The reason for the excessive consumption of oil is to remove the oil; more It is the engine oil. The main reason is that the piston and the cylinder wall are too large, the piston ring is worn out or the elasticity is lacking, the valve guide is worn out too much, and the valve stem oil seal is damaged. The use of the Chi Naipu machine super strong correction agent can greatly improve the piston ring. Sealing; correcting worn internal parts; reducing the cost of oil.
