Abstract
The utility model relates to a supercharger for internal combustion engine which belongs to the technical field of the supercharging of the internal combustion engine. An external casing of the utility model is composed of three parts of an air feed pump shell, an exhaust pump shell and a middle shell. A compressor, an air inlet and an air outlet are arranged in the air feed pump shell. A turbine, an exhaust gas outlet and an exhaust gas inlet are arranged in the exhaust pump shell. A rotating shaft passes through the air feed pump shell and the exhaust pump shell on the both sides. A compressor and a turbine are fastened on the both ends of the rotating shaft, and are connected with a rotating shaft key. An oil inlet and an oil outlet are arranged on the middle shell. An adjustable valve is arranged in the channel of the air outlet. The utility model can obtain the effects that the oil is saved, the power output of the power output of the internal combustion engine is increased, and the pollution is reduced. The utility model not only solves the supercharging degree of a type under the different loads, but also can make adjustments to adapt different types. Thus, the utility model can make a reconstruction on the original internal combustion engine, and can also be applied to the dynamic matching of the new automotive type.
Description
Technical field
The utility model relates to supercharging of internal combustion engine technical field, especially internal combustion engine turbocharger.
Background technique
As everyone knows, contain bigger energy in the high-temp waste gas with certain pressure that cylinder of internal-combustion engine is discharged, this part energy substantially all is discharged in the atmosphere at present, wastes.Not only environment is affected, also increased the energy consumption of internal-combustion engine.Though the multiple waste gas supercharging technology that utilizes is also arranged at present, structure is complicated, and generally can only adapt to a kind of type.
Summary of the invention
In order to make full use of this part energy, the purpose of this utility model is to provide a kind of internal-combustion engine booster, and it can change the portion of energy in the waste gas into compresses fresh air is done, and adapts to different types of machines.
The technical solution of the utility model is this kind internal-combustion engine booster, it forms frame by air inlet pump case, exhaust pump case, middle case three parts, be provided with the receded disk impeller gas compressor in the air inlet pump case, be axially arranged with air intlet, radially be provided with air outlet slit along gas compressor; Be provided with turbine in the exhaust pump case, to establishing waste gas outlet, radially be provided with exhaust gas inlet along turbine shaft; Rotating shaft is by both sides air inlet pump case, exhaust pump case, and gas compressor and turbine are fastened on the two ends of rotating shaft and are connected with the rotating shaft key; Be provided with filler opening on middle case top, the bottom is provided with oil outlet; In the cavity of air outlet slit, be provided with modulating valve.
The utility model utilizes waste gas to blow the turbine acting, drives gas compressor by turbine, and fresh air is pressed into cylinder.
The beneficial effects of the utility model are: can reach fuel-economizing, the output of increasing combustion engine power reduces the effect of polluting.After modulating valve is set, not only solve the degree of boost under a kind of type different load, regulate adapting to different types.The utility model both can be transformed on original internal-combustion engine, and it is supporting also to can be applicable to new model power.
