1. Float oil filter: in order for the oil pump to work well, it is necessary to remove the large particle impurities from the lubricating oil before entering the oil pump. This task is the responsibility of the oil filter. It is connected to the oil inlet of the oil pump. When the oil pump works, the oil is sucked in through the slit between the cover and the float. After filtering the thick impurities through the filter net, the oil pipe welded on the float enters the oil pump. When the filter is silted up, the suction of the oil inlet increases, overcoming the strong filter and causing the bad mouth to leave the cover, the oil will enter the oil suction pipe directly from the ring mouth without the filter.
　　2. The primary filter is in series between the oil pump and the main oil channel, so it is also called a full-flow filter to remove large impurities in the oil. It is mainly composed of upper cover, shell, paper filter element and bypass valve. When the engine is working, the lubricating oil with pressure is sent into the cavity around the filter element. The larger impurities in the oil are blocked by the paper filter element, while the clean lubricating oil enters the filter element's cavity and then enters the main oil passage of the cylinder block through the oil outlet.
