The raesonof engine oil pressure abnormal and damage of it

 In addition to pump oil pump capacity, the oil flow through the area (refer to oil path, filter and lubrication of parts of space, etc.) and the oil viscosity and other factors will affect oil pressure.
    Engine must maintain normal oil pressure. If oil pressure is too low, the friction surface due to inadequate lubrication and wear accelerated; If oil pressure is too high, easy to seal, tubing crush and consume engine power. Car driving, the lubricating oil pressure is generally maintained at 0.2-0.5mpa. The engine idle, the oil pressure should not be less than 0.1mpa.

    1, engine oil pressure is too low, lubrication will damage the engine, resulting in lubrication, cooling and cleaning bad, will cause the adhesive wear parts. Crankshaft main journals and connecting rod bearing clearance between journal and is too large, the oil viscosity is too low and the filter will cause low oil pressure rupture.

    2, engine oil pressure is too high, though not common, but also undermine the normal lubrication. Such as the oil viscosity is too large, metamorphic knot plastic, filter and oil duct blockage, pressure regulator improperly adjusted or not to open will cause the oil pressure is too high.

    3, excessive oil consumption, abnormal engine oil consumption and the ratio of gasoline is 0.5% -1%, if not greater than 1% of normal. In addition to the reasons for excessive oil consumption oil leakage, the more oil is burned. The main reason is: the piston and cylinder wall clearance is too large; piston ring wear off or even less elastic; valve guides wear off even; valve rod oil seal damage. Using Chi-resistant super popular engine repair agent can greatly improve piston ring sealing, repair worn internal parts, reduced oil consumption.
