Description

Technical Field

[0001] The present invention relates to the technical field of engines, and particularly to an oil-gas separation device for a large-displacement supercharged engine. Background Art

[0002] A supercharged engine refers to an engine equipped with a turbocharger. A turbocharger is actually an air compressor that increases the intake air volume by compressing air. It uses the inertial impulse of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller. The impeller compresses the air sent from the air filter pipe and makes it enter the cylinder under pressure. When the engine speed increases, the exhaust gas discharge speed and the turbine speed increase synchronously, and the impeller compresses more air into the cylinder. The increased pressure and density of the air allow more fuel to be burned. By correspondingly increasing the fuel quantity and adjusting the engine speed, the output power of the engine can be increased.

[0003] Since the piston of the engine is in motion, there must be a gap between the piston ring and the cylinder barrel. Therefore, during the operation of the engine, part of the burned exhaust gas in the combustion chamber will leak into the crankcase, which is called "crankcase blow-by". The accumulated exhaust gas will cause excessive pressure inside the engine, damage the sealing surface and cause oil leakage and other problems. Therefore, it is necessary to discharge the crankcase blow-by in a certain way.

[0004] However, when the engine is working, the temperature is relatively high, and the atomized engine oil will be mixed with the crankcase blow-by to form an "oil-gas mixture". If the crankcase blow-by is directly discharged, the engine oil will be discharged together, resulting in excessive consumption of the engine oil and seriously affecting the reliability of the engine. When the "oil-gas mixture" is directly discharged outdoors, it will cause pollution to the environment and affect the ecological environment. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an oil-gas separation device for a large-displacement supercharged engine, which solves the problems that when the engine is working, the temperature is relatively high, the atomized engine oil will be mixed with the crankcase blow-by to form an "oil-gas mixture", if the crankcase blow-by is directly discharged, the engine oil will be discharged together, resulting in excessive consumption of the engine oil and seriously affecting the reliability of the engine, and when the "oil-gas mixture" is directly discharged outdoors, it will cause pollution to the environment and affect the ecological environment.

[0006] The above technical object of the present invention is achieved by the following technical solutions:

[0008] By adopting the above technical solution, by arranging the separation component, the oil contained in the crankcase blow-by gas entering the inside of the filter chamber can be effectively filtered, achieving the effect of oil-gas separation, effectively preventing environmental pollution caused by direct gas discharge, reducing unnecessary loss and waste of oil at the same time, and being able to perform two-stage separation to improve the separation effect.

[0009] Preferably, the separation component includes: two mounting blocks, both of the two mounting blocks are fixedly mounted on the bottom surface inside the filter chamber, a mounting groove is opened on the top surface of the mounting block, a partition plate is fixedly mounted inside the filter chamber, two rotating holes are opened on the top surface of the partition plate, a driving motor is fixedly sleeved inside the mounting groove, one end of the rotating shaft of the driving motor is fixedly mounted with a connecting column, an adjusting rod is movably sleeved on the outer wall of the connecting column, a plurality of filter elements are fixedly mounted on the outer wall of the adjusting rod, a liquid dropping plate is movably sleeved on the inner wall of the rotating hole, a mounting hole is opened on the top surface of the liquid dropping plate, and the mounting hole is fixedly sleeved with the inner wall of the adjusting rod.

By arranging the adjusting rod, the filter elements fixed on the surfaces of the two adjusting rods can perform two-stage separation on the crankcase blow-by gas entering the inside of the filter chamber. By arranging the adjusting rod, the oil attached to the surface of the filter element will fall into the inside of the liquid dropping plate under the influence of gravity and enter the lower part of the partition plate through the holes on the surface of the liquid dropping plate, realizing complete oil-gas separation.

By setting the liquid discharge pipe, it can be better connected to the fuel filling port of the crankcase, facilitating the feeding of the filtered engine oil into the crankcase for secondary utilization, avoiding unnecessary waste.

[0017] Preferably, a pipe joint is fixedly sleeved inside each of the intake pipe, the exhaust pipe and the liquid discharge pipe.

[0019] Preferably, two heating wires are fixedly installed on the top surface of the partition plate.

[0020] By adopting the above technical solution, by setting the heating wires, when the outside temperature is too low, starting the heating wires can heat the inside of the filtering bin, avoiding the phenomenon that the filtered engine oil solidifies due to the influence of the temperature, and improving practicability.

[0021] Preferably, a plurality of connection holes are formed on the top surface of the top cover, a plurality of bolts are movably sleeved inside the connection holes, a plurality of threaded holes are formed on the top surface of the filter block, the positions of the threaded holes correspond to those of the connection holes, and the outer wall of the bolt is threadedly connected to the inner wall of the threaded hole.

[0023] In summary, the present invention mainly has the following beneficial effects:

By setting up a rubber pad, the sealing performance of the filter paper is improved, preventing the engine oil from falling through the gap between the filter paper and the inner wall of the installation bin, and improving the filtering effect. By setting up an intake pipe, it can be better connected to the crankcase air outlet, facilitating the direct reception of the exhausted gas discharged from it. By setting up an exhaust pipe, it can be better connected to the engine combustion chamber, facilitating the feeding of the filtered gas into the combustion chamber for combustion utilization, improving environmental protection. By setting up a drain pipe, it can be better connected to the fuel filling port of the crankcase, facilitating the feeding of the filtered engine oil into the crankcase for secondary utilization, avoiding unnecessary waste. By setting up a pipe joint, the connection of the intake pipe, exhaust pipe and drain pipe is made more convenient, improving practicality. By setting up a heating wire, when the outside temperature is too low, starting the heating wire can warm the inside of the filtering bin, avoiding the phenomenon that the filtered engine oil solidifies due to the influence of temperature, and improving practicality.
