Abstract
The utility model relates to an automatic control type vehicle exhaust gas efficient purifying device. The utility model comprises an exhaust gas recycling valve, which is installed on the air intake pipe of the engine, and a catalytic purifying device, which is installed on the exhaust gas pipe, the utility model is characterized in that an exhaust gas flow controlling valve is installed on the exhaust gas pipe, one outlet opening B1 of the exhaust gas flow controlling valve is connected with the exhaust gas interface B of the exhaust gas recycling valve, the air intake pipe opening A opposite to the opening and the closing of the exhaust gas recycling valve is connected with the vacuum degree controlling interface A1 on the air intake pipe, and the exhaust gas outlet opening of the exhaust gas recycling valve is connected with the air intake pipe. The utility model has the advantages that the utility model enables HC, CO and NOx emitted in the vehicle exhaust gas to reach the emission standards, the exhaust gas harnessing cost is reduced, because the automatic exhaust gas circulation quantity control is adopted, the power output of the engine is guaranteed, and in addition, the device enable the working stability to be enhanced, and the service life to be increased.
Description
Technical field
The utility model relates to the treatment device of vehicle emission pollution gas, relate in particular to a kind of self-controlled type vehicle exhaust high-level cleaner.
Background technique
At present, normally adopt ternary catalyst purifier for the exhaust emissions treatment measures of automobile, so that the harmful gas that is discharged is carried out comprehensive improvement.But ternary catalyst purifier not only itself involves great expense, and service condition is very harsh, and the working range of air fuel ratio is very narrow.Make the cost maintenance expense of complete purification plant become expensive more in order to keep this operating conditions.Because working range is narrow, the life-span of working stability and parts all can be affected.China also pays much attention to for the motor vehicle exhaust emission pollution problem, and corresponding some standards of having formulated only use catalytic cleaner also to be difficult to arrive the exhaust emission control criterion in addition.Therefore administering automobile exhaust pollution is an extremely urgent problem.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of self-controlled type vehicle exhaust high-level cleaner is provided.This device uses EGR Technology to make its arrival standard, and adopts the technology of controlling exhaust gas flow automatically to guarantee the power output of motor.
The purpose of this utility model realizes by following technical proposals, self-controlled type vehicle exhaust high-level cleaner of the present utility model comprises an exhaust gas recirculation valve, this exhaust gas recirculation valve is installed on the engine air inlet tube, a catalytic cleaner is installed on the outlet pipe, an exhaust gas flow control valve also is installed on outlet pipe, an outlet B ' of this exhaust gas flow control valve is communicated in the waste gas interface B of exhaust gas recirculation valve, then connect vacuum degree control interface A ' on the suction tude position for the air inlet mouth of pipe A of the unlatching closure of exhaust gas recirculation valve, the waste gas outlet C of exhaust gas recirculation valve connects suction tude.
Described exhaust gas flow control valve is made of a kind of like this structure, and its internal diameter is a kind of venturi tubulose structure, thereby makes exhaust flow become turbulent flow.
Principle of the present utility model is that the waste gas that utilizes motor to discharge enters suction tude through exhaust gas flow control valve and exhaust gas recirculation valve, makes it to increase the thermal capacity of combustion gas, thereby reduces chamber temperature, makes NO
xGrowing amount reduces, and importantly, for overcoming the influence of cycle gas to engine power, has then adopted the exhaust gas flow control valve to guarantee the power output of motor with automatic control exhaust gas flow.
The utility model has the advantages that can motor vehicle exhaust emission HC, CO and NO
xReach emission standard, and reduced the treating tail gas cost, owing to adopted automatic control waste gas circulation amount, thus guaranteed the power output of motor, in addition, this device can make its working stability improve, and the life-span is increased.
