Description
Technical field
The present invention relates to a kind of lubricating oil, be specifically related to a kind of dual-fuel engine special lube of long service life.
Background technology
Dual-fuel engine uses Sweet natural gas or liquefied petroleum gas (LPG) to be fuel, its calorific value is very high, exhaust emissions temperatures as high 480 DEG C, exceed 180 DEG C-200 DEG C than the temperature of common I. C. engine oil, engine combustion temperatures is high, causes lubricating oil evaporation loss large, NOx too high levels, I. C. engine oil very easily makes NOx that oxidation or nitration occur, and increases greasy filth and carbon deposit, thus boost engine weares and teares, deterioration of lubricant is aging; Further, compressed natural gas or the unlubricated effect of liquefied petroleum gas (LPG) self, therefore, require that the ash content of I. C. engine oil is moderate, make the ash content lubricate be deposited on valve and valve seating, ash content is too low, do not have lubrication, easily cause intake valve, vent valve and the prooving of valve seat, ash content is too high, engine can be caused to light a fire in early days and sparking plug pollution, affect engine power, generate hard settling in engine surface, carbon deposit is too much, valve melting loss.
