Gas-oil separation structure with crankcase for ventilation and operation method thereof

Abstract

The invention relates to a gas-oil separation structure with a crankcase for ventilation and an operation method thereof. The gas-oil separation structure comprises a spindle body, a plurality of channel bodies, partition boards and a threaded body, wherein the plurality of channel bodies are evenly arranged around the spindle body, the threaded body is positioned on the spindle body and used for tightly screwing the gas-oil separation structure at the front end of the a hollow cam shaft, the plurality of channel bodies are internally hollow to form gas inlet channels, and opening portions of the gas inlet channels are in the wedge shape. The spindle body is hollow to form a spindle cavity, and the partition boards are arranged in the spindle cavity and used for leading mixed gas to pass through cavities between the partition boards so as to achieve gas-oil separation.

Description

technical field [0001] The invention relates to an oil-gas separation structure, in particular to an oil-gas separation structure for crankcase ventilation and an operation method thereof. Background technique [0002] With the promulgation of emission regulations, the requirements for vehicle and engine emissions are becoming more and more stringent, and the quality of the crankcase ventilation system has a great impact on engine emissions. At present, in the engine, the oil gas that escapes into the crankcase directly enters the crankcase ventilation system, and then the oil and gas are separated, and the separation effect is not good, so that the gas entering the combustion chamber contains a certain amount of engine oil, resulting in the phenomenon of engine oil burning , At the same time, carbon deposits are formed in the combustion chamber, which is not conducive to the normal operation of the engine for a long time. Simultaneously, the crankcase ventilation system us...

Problems solved by technology

At present, in the engine, the oil gas that escapes into the crankcase directly enters the crankcase ventilation system, and then the oil and gas are separated, and the separation effect is not good, so that the gas entering the combustion chamber contains a certain amount of engine oil, resulting in the phenomenon of engine oil burning At the same time, carbon deposits are formed in the combustion chamber, which is not conducive to the normal operation of the engine for a long time

At the same time, the layout of the crankcase ventilation system currently used on most engines is relatively complicated, taking up a large space and requiring a large number of components, which is not conducive to the layout of the whole machine in a limited space.
