Oil Jet
Oil jet for cooling and lubricating the pistons are provided in the cylinder block sub-assembly.
These Oil jets contain a check valve to prevent oil from being fed when the oil pressure is low. This prevents the overall oil pressure in the engine from dropping.
Oil Filter
An oil filter with a replaceable oil filter element is used. The oil filter element uses a high-performance filter paper to improve filtration performance. It is also combustible for environmental protection.
An aluminum alloy oil filter cap assembly is used to extend its life.
