Description
Technical Field
The utility model relates to the technical field of oil-gas separation of engines, in particular to a side air inlet oil-gas separator for an engine.
Background
The oil-gas separator is connected beside the crankcase ventilation valve of the engine, because the blow-by gas of the cylinder and the engine oil vapor can generate pressure when the engine works, the engine is damaged, so the crankcase ventilation valve is needed to generate vacuum, and because a large amount of engine oil vapor exists in the gas pumped out by the crankcase ventilation valve, the oil-gas separator mainly separates the engine oil vapor into engine oil and steam, so the engine oil flows back into the engine for reuse after being gathered by the bottom shell, and the steam flows to the engine for re-combustion, thereby preventing the engine from directly entering the atmosphere and causing atmospheric pollution.
The utility model in China, such as application number 201520630355.9, discloses an oil-gas separator, and relates to the field of mechanical manufacturing. The PCV valve comprises a PCV valve cover, a PCV valve base, a main shell, a filter element, a PCV valve diaphragm, a PCV valve spring, an O-shaped sealing ring and a bracket insert; the PCV valve cover, the PCV valve base and the main shell are sequentially and tightly connected, the side wall of the PCV valve base is provided with an air outlet, a PCV valve membrane is arranged between the PCV valve cover and the air outlet of the PCV valve base, a PCV valve spring is arranged between the PCV valve membrane and the PCV valve base, the side wall of the main shell is provided with a mixed air inlet, meanwhile, a filter element and an oil return port are arranged in the main shell, and the filter element comprises a filter element shell, filter cotton, a filter element regulating valve, a filter element seat, a filter element spring piece and a filter element lower shell; however, in the using process of the structure, the oil return speed is slower, so that the lubricating oil in the main shell is accumulated, the integral vibration is larger, the loosening or falling-off of the connecting part of the pipeline and the connecting part of the main shell and the engine is easy to occur, the filter cotton is easy to fall off due to the larger vibration, the filter cotton is blocked or loses the filter function, and the using stability is poor; moreover, because the oil return hole is arranged in the middle of the filter core seat, a gap is reserved between the lower end of the filter core shell and the filter core seat, otherwise, lubricating oil filtered by filter cotton cannot flow to the oil return hole, filtered gas is easy to enter into a mixed gas inlet from the gap between the lower end of the filter core shell and the filter core seat to cause gas leakage, the mixed gas is also easy to directly enter into a filter cavity from the gap between the lower end of the filter core shell and the filter core seat to cause the reduction of the filtering efficiency, and the mixed gas also enters into a filter core regulating valve upwards from the middle of the filter core seat, so that the mixed gas is easy to enter into the oil return hole from the oil return hole to return to the cylinder body again, and the oil-gas separation efficiency is low.
