Description
Technical field
The utility model relates to a kind of pressurized machine, is specially a kind of exhaust-gas turbocharger that is applied on the petrol engine.
Background technique
Pressurized machine can improve petrolic air inflow, thereby improve the power and the moment of torsion of motor, its introducing makes petrol engine export more powerful motivation under the prerequisite that does not change cylinder diameter, and exhaust-gas turbocharger obtains using comparatively widely, it need not power, the exhaust gas-driven turbine high speed rotating that utilizes motor to discharge, send in the engine cylinder after driving the coaxial air compression of press machine blade constant speed rotation the press machine inspiration, make the interior air density of cylinder increase sharply, oil inflame is more abundant, thereby improve the power of motor, improve burning situation, reduce emission of automobile wastes and pollute; Because oil inflame is more abundant, engine consumption is reduced simultaneously.
But traditional exhaust-gas turbocharger has following defective: 1. when engine stoping operation, can not in time the gas in the suction tude be drained, it is excessive to be easy to build-up of pressure, damages pressurized machine even motor; 2. suck the air of many dirt easily, the parts such as cylinder of engine interior are caused damage.These two defectives petrol engine embody on exhaust-gas turbocharger particularly evident, at first, the petrol engine rotating speed is very high, the exhaust-gas turbocharger rotating speed of Pei Heing is also very high with it, after petrol engine stopped, pressurized machine can remain in operation because of bigger inertia, continued to suck air, be easy to cause the surge of pressurized machine, so that damage; Secondly, in order to prolong petrolic working life, need the cleanliness that sucks air is proposed higher requirement.Based on above 2 points, petrol engine need be made corresponding improvement in configuration aspects with exhaust-gas turbocharger.
The model utility content
Technical problem to be solved in the utility model provides a kind of petrol engine exhaust-gas turbocharger, and its pressure release in time and filtration suck air, thereby eliminates defective in the above-mentioned background technology.
For achieving the above object, the utility model is by the following technical solutions:
The petrol engine exhaust-gas turbocharger comprises turbine chamber and pressurized machine, and described turbine chamber comprises the turbine chamber suction port, and this turbine chamber suction port links to each other with petrolic gas exhaust manifold; The turbine chamber relief opening, this turbine chamber relief opening connects the petrol engine outlet pipe; And be installed in turbine in the turbine chamber;
Described pressurized machine comprises the pressurized machine suction port, and this pressurized machine suction port connects the gasoline engine inlet-air pipe; The pressurized machine relief opening, this pressurized machine relief opening is communicated with petrolic intake manifold; And be installed in impeller in the pressurized machine;
Described turbine and impeller coaxial rigid connection;
Be that with the remarkable difference of traditional exhaust-gas turbocharger described pressurized machine also is provided with Decompression valves, on the described gasoline engine inlet-air pipe air filter be set.
As a kind of improvement, described air filter is an air-strainer.
As a kind of improvement, be provided with lubricating fitting in the connection place of turbine and impeller.
The utility model the utlity model has following beneficial effect owing to adopted above structure:
1. pressurized machine is provided with Decompression valves, can stop at petrol engine, and pressurized machine sucks because of inertia remains in operation after the air, pressure air too high in the pressurized machine is discharged, thereby effectively prevent the surge of pressurized machine, prolongs the working life of pressurized machine;
2. suction tude of the present utility model is provided with air-strainer as air filter, inhaled air can be filtered, and has guaranteed to suck the cleanliness of air, prevents engine cylinder because sucking impurity causes damaging, and has improved integral working.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the petrol engine exhaust-gas turbocharger comprises turbine chamber 1 and pressurized machine 2, and described turbine chamber 1 comprises the turbine chamber suction port that links to each other with the petrol engine gas exhaust manifold, the turbine chamber relief opening that links to each other with the petrol engine outlet pipe, and be installed in the interior turbine 11 of turbine chamber; Described pressurized machine 2 comprises the pressurized machine suction port that links to each other with the gasoline engine inlet-air pipe, the pressurized machine relief opening that is communicated with the gasoline engine inlet-air manifold, and be installed in impeller 21 in the pressurized machine 2; Described turbine 11 and impeller 21 coaxial rigid connection, the connection place is provided with lubricating fitting 3, be with the remarkable difference of traditional exhaust-gas turbocharger, described pressurized machine 2 also is provided with Decompression valves 22, on the described gasoline engine inlet-air pipe air filter 4 is set, in the present embodiment, this air filter 4 is an air-strainer.
Working principle of the present utility model is as shown in Figure 2:
The off-gas flows impulse turbine 11 of high temperature and high speed makes turbine 11 high speed rotating, and the pressure of waste gas, flow velocity are high more, and turbine 11 rotating speeds are also high more.Waste gas by turbine 11 enters atmosphere by the petrol engine outlet pipe at last.Simultaneously, with the impeller 21 of turbine 11 coaxial rigid connection also with identical speed, will suck in the pressurized machine 2 via the clean air of air filter 4, gas forms pressurized gas after supercharging, enter cylinder after the cooling of pressurized gas through intercooler 5.
After petrol engine stopped, the impeller of pressurized machine 2 21 can be because of the inertia suction air that remains in operation, and this moment, Decompression valves 22 can be discharged pressure airs too high in the pressurized machine 2, thereby effectively prevented the surge of pressurized machine 2, increased the service life.
The utility model is not limited to above-mentioned embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done all falls among the protection domain of the present utility model.
