2.1.3.1. General information

The system of greasing works under pressure, oil passes through the oil filter. On Mazda engines the non-polluting oil filter with a replaceable filtering element is established. Greasing system – with polnopotochny purification of oil and with supply of oil under pressure to the main moving details and engine knots. The system consists of an oil case, the shesterenchaty oil pump with a maslopriyemnik, the polnopotochny mesh oil filter, the sensor of pressure of oil and oil valves. The oil pump takes away oil from the pallet of a case of the engine and submits it to the oil filter. From forcing of the oil pump there is perepuskny a valve. At too high pressure of oil the valve opens, and the part of oil flows down back in the engine pallet. Through the middle of a filtering element of the oil filter pure oil arrives to the trunk oil main. At a contamination of the filter bypass the valve located in the case of the oil filter, submits not filtered oil directly to the trunk oil main. In a branch pipe of the oil filter there is a return valve which interferes with a devastation of oil channels and hydraulic pushers of valves of the engine. Channels depart from the trunk oil main for greasing of bearings of the crankshaft. Through inclined openings in the crankshaft oil moves to shatunny bearings, and from there is sprayed on piston fingers and cylinders. At the same time on ascending channels oil moves in a head of the block of cylinders and ensures functioning greasing of bearings of a camshaft and hydraulic pushers.

The pallet of an oil case is made of multilayered steel with high factor of damping. On LF engines and L3 the maslookhladitel with a water maslookhlazhdeniye is also established.

ATTENTION On the cars equipped with engines with catalytic converter, it is necessary to watch that oil level on masloizmeritelny щупу was not higher than a maximum mark. If in the car with catalytic converter too much oil was filled in, its superfluous part should be removed from a case with means plum or a suction (the special vacuum pump), otherwise not burned down oil will get into system of production of the fulfilled gases and can destroy catalytic converter.
