Problems solved by technology
The exhaust gas that escapes into the crankcase contains gas phase and liquid phase. If these substances are not removed in time, they will accelerate the deterioration of the engine oil and cause the parts to be corroded or rusted.
In addition, due to the exhaust gas escaping into the crankcase, the pressure in the crankcase will increase. When the pressure increases to a certain level, the oil will leak from the crankshaft oil seal and the crankcase gasket.

Embodiment Construction
[0039] Such as Figure 1-Figure 4 As shown, the gas-liquid separation device 100 of the present invention may generally include a body 10 and a centrifugal member 20 .
[0040] Wherein, the body 10 has a hollow central channel 15 , a bottom opening 11 at the bottom of the central channel 15 , a top opening 12 at the top of the central channel 15 , and a circumferential sidewall opening 13 . The circumferential side wall opening 13 is located on the circumferential side wall 10 a of the central channel 15 .
[0041] Wherein, the centrifugal member 20 is arranged in the central flow channel 15, and the centrifugal member 20 is arranged at an appropriate height in the central flow channel 15 so that the exhaust gas passing into the central flow channel 15 passes through the centrifugal Droplets condense at the member 20. The liquid droplets are thrown radially outward to the circumferential side wall 10 a of the central channel 15 by the centrifugal force generated by the centr...

The invention provides a gas-liquid separating device and a crankcase ventilating structure. The gas-liquid separating device comprises a body and a centrifugal piece, wherein the body is provided with a hollow centre runner, a bottom end opening which is positioned at the bottom end of the centre runner, a top end opening which is positioned at the top end of the centre runner and a circumferential side wall opening which is positioned at the circumferential side wall of the centre runner; the centrifugal piece is arranged in the centre runner and is configured for enabling liquid drops to be condensed by waste gas filling into the centre runner at the position of the centrifugal piece, and the liquid drops can be radially and outwards thrown to the circumferential side wall of the centre runner by a centrifugal force generated by the centrifugal piece. The crankcase ventilating structure comprises a crankcase, a cylinder head cover and the gas-liquid separating device, wherein the crankcase and the cylinder head cover are communicated through a waste gas passage, and the gas-liquid separating device is arranged in the waste gas passage. Each liquid drop can be thrown to the circumferential side wall by the centrifugal piece, most of the liquid drops is separated from the body through the circumferential side wall opening, few liquid drops are separated from the body through the bottom end opening, and thus the gas-liquid separation of the waste gas in the body can be basically completed by the gas-liquid separating device provided by the invention.
Description
technical field [0001] The invention relates to a gas-liquid mixture separation technology, in particular to a gas-liquid separation device and a crankcase ventilation structure. Background technique [0002] Most of the exhaust gas generated by engine combustion is discharged out of the car through the exhaust pipe, and a small part of the exhaust gas escapes into the crankcase through the gap between the piston ring and the cylinder wall. The exhaust gas that escapes into the crankcase contains gas phase and liquid phase. If these substances are not removed in time, the deterioration of the engine oil will be accelerated and the machine parts will be corroded or rusted. In addition, due to the exhaust gas escaping into the crankcase, the pressure in the crankcase will increase. When the pressure increases to a certain level, the oil will leak from the crankshaft oil seal and the crankcase liner. [0003] Therefore, it is necessary to provide a technology capable of separa...
