Abstract
A gasoline engine turbocharger turbine casing integrated with an exhaust pipe manifold comprises a turbine casing and the exhaust pipe manifold integrated with the turbine casing. The turbine casing is provided with a bearing connecting flange, a bypass air-release valve mounting bushing hole, a waste-gas outlet connecting flange and a turbine casing gas inlet, and a turbine casing channel and a bypass air-release valve hole are arranged in the turbine casing. The exhaust pipe manifold is provided with a flange connected with an engine, and the flange connected with the engine is provided with four cylinder channels and a plurality of fastening bolt holes connected with the engine. A main channel is arranged in the exhaust pipe manifold, communicated with the four cylinder channel, and communicated with the turbine casing gas inlet. Since the turbine casing is integrated with the exhaust pipe manifold, the joint between the turbine casing channel in the turbine casing and the main channel in the exhaust pipe manifold of the engine is subjected to circular-arc transition and further provided with a turbine casing channel tongue tip.

Using petrol engine at present is what to separate with the turbine box housing in the turbosupercharger with the engine exhaust pipe manifold; The assembling of turbine box housing and engine exhaust pipe manifold is shown in accompanying drawing 6; Engine exhaust pipe manifold 6 is connected into one with turbine box housing 3 usefulness clamping bolts 5, and the flange contact facings on flange on the engine exhaust pipe manifold 6 and the turbine box housing 3 is provided with sealing flange pad 4.Owing to be split-type structural, a plurality of parts are installed together, and can cause the runner loss of engine exhaust process excessive, and the engine exhaust capacity usage ratio descends, and also can cause problems such as gas leakage simultaneously.Especially on the miniature high-speed petrol engine, very narrow and small because of installing space, therefore too much part can cause a series of difficulties such as installation, maintenance.So this inadaptability in structure is in the high efficiency petrol engine demand of miniature high-speed.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of existing technology and a kind of petrol engine turbocharger turbine shell that the turbine box housing and the enmgine exhaust of turbosupercharger are become one is provided.
The technological scheme of the utility model is: a kind of petrol engine turbocharger turbine shell that becomes one with the outlet pipe manifold; It comprises turbine box housing and the outlet pipe manifold that becomes one with the turbine box housing, and arc transition is adopted in the connection place of turbine box housing and outlet pipe manifold.
The turbine box housing is provided with bearing support connecting flange, bypass venting valve mounting bush hole, waste gas outlet connecting flange and the turbine box suction port that connects with the pressurized machine bearing support, in the turbine box housing, is provided with turbine box runner and bypass bleed valve aperture of door.
The outlet pipe manifold is provided with the flange that connects with motor; With flange that motor connects on be provided with the first single cylinder runner, the second single cylinder runner, the 3rd single cylinder runner and the 4th single cylinder runner, with flange that motor connects on also be provided with a plurality of fastening screw keyholes that connect with motor.In the outlet pipe manifold, be provided with manifold flow passage, the first single cylinder runner, the second single cylinder runner, the 3rd single cylinder runner and the 4th single cylinder runner communicate with manifold flow passage, and manifold flow passage communicates with the turbine box suction port.
After turbine box housing and outlet pipe manifold became one, arc transition was adopted in the turbine box runner in the turbine box housing and the connection place of the manifold flow passage in the engine exhaust pipe manifold, and its connection place also is provided with the volute flow passage the tip of the tongue.
The further technological scheme of the utility model is: in the outlet pipe manifold, be provided with a runner, the second single cylinder runner and the 3rd single cylinder runner communicate with runner, and runner communicates with manifold flow passage.
The utility model compared with prior art has following characteristics:
A, the turbine box housing that adopts the utility model to provide need not be done any change to other part of existing turbosupercharger, just can join with other part luggage of existing turbosupercharger.
B, since turbine box housing and petrol engine outlet pipe manifold be linked together; Reduced connecting flange face, clamping bolt and pad, reduced the quantity of part, the gross weight of engine exhaust pipe manifold and turbine box housing is alleviated; The machined part decreased number, cost reduces.
C, since turbine box housing and petrol engine outlet pipe manifold be linked together; Can get rid of because the runner of outlet pipe manifold and pressurized machine is installed the decentraction that causes because divide to offer; Improved the engine exhaust energy utilization ratio; Reduce delivery temperature, help reducing discharging simultaneously and improve fuel economy.
D, since turbine box housing and petrol engine outlet pipe manifold be linked together, assemble and keep in repair very convenient.
Further describe below in conjunction with accompanying drawing and embodiment detailed structure the utility model.
