Description
The utility model relates to a kind of carburetor type gasoline engine car exhaust emissions comprehensive treatment device, and the utility model is applicable to various carburetor type gasoline engine cars.
At present, China's gasoline engine car adopts the carburetor type fuel-feed system mostly, and the type motor vehicle exhaust emission exceeds standard seriously, and pollutant emission concentration height is the primary pollution source of current urban atmospheric pollution.Along with the formulation of Environmental Protection in China reform and the increasing for the treatment of vehicle exhaust dynamics, domestic each producer develops many environment-friendly products that are used to administer automobile exhaust pollution, but in practice, still exists following problem:
1, clean-up effect is undesirable, and the three kinds of pernicious gases of CO, HC, Nox to containing in the vehicle exhaust can not play cleansing action, particularly Nox simultaneously and can not get effectively reducing.
2, there are not the comprehensive regulation of consideration to whole automobile engine system, air/fuel ratio amplitude broad.Administer exhaust emissions and a certain device is installed merely, both out of reach had also influenced engine power performance and fuel economy to the clean-up effect of CO, HC, Nox pernicious gas.
3, existing clean-up device can not adapt to the existing fuel oil actual conditions of China, can not under various working conditions, stablize reach discharging standards [GB14761-1999] and also service life shorter, bring bigger economical burden to the user.
The purpose of this utility model is exactly the deficiency that exists on existing treating vehicle exhaust technology and the product, provide a kind of under the prerequisite that does not influence engine power performance raising fuel economy, effectively reduce the carburetor type gasoline engine car exhaust emissions comprehensive treatment device of motor vehicle exhaust emission concentration, its maximum characteristics are applied ranges, comformability is strong, regulation effect is good, but the exhaust emission under the various working conditions in the actv. solution running car.
The improvement that motor vehicle exhaust emission is polluted is a system engineering, engine power performance, and fuel economy and effluent standard, these three important indicators are inseparable entities.When definite auto pollution thing control emission technical scheme, must solve tractive performance and fuel economy conscientiously, just can reach proper effluent standard, in other words, resolve the emission problem of carburetor type automobile, when determining to administer technical scheme, must use complex art and coordinate dynamic property on the whole, the relation of economy and effluent standard could the stabilizing effective effluent standard of regulation and the desirable clean-up effect of reaching.
The purpose of this utility model can realize by following measure:
1, a kind of carburetor type gasoline engine car exhaust emissions comprehensive treatment device, include exhaust gas reclrculation pipe (1), gasifier (4), carburettor (5), airfilter (6), vacuum lamp (8), current distributor (10), air intake branch (12), exhaust branch pipe (13) and noise silencer (15), vacuum (8) is provided with Spark Delay Valve (9), and current distributor (10) connects high-frequency igniter (11); Carburettor (5) is provided with main flow metering-orifice (7); Exhaust gas reclrculation pipe (1) is provided with motorized valve (2), and motorized valve (2) is connected with EUU electric controller (3); Between exhaust branch pipe (13) and noise elimination (15), be provided with catalytic convertor (14).
Advantage of the present utility model:
1, improves engine power performance and fuel economy effectively, can reduce oil consumption more than 10%.
2, satisfy the new automobile exhaust emission standard of country, reach desirable clean-up effect, CO, HC, three kinds of cleaning harmful gas rates of Nox all can reach more than 75% in the 50000 kilometers whole of lifes that travel.
3, strong, the carburetor type automobile of applied range, comformability all can adopt the utility model and can adapt to the existing fuel oil actual conditions of China.
4, automobile can be issued to effluent standard at various working conditions in the process of moving.
Description of drawings is as follows:
Fig. 1 is the utility model structural representation.
Describe in detail by embodiment below in conjunction with accompanying drawing:
The utility model mainly is to improve on present carburetor type engine petrol.Following parts have promptly been set up: high-frequency igniter 11, spark delay valve 9, main flow metering-orifice 7, motorized valve 2, ECL electric controller 3 and catalytic convertor 14.
1, the vacuum lamp 8 that driving engine gasified between device 4 and the current distributor 10 disconnects, be connected with vacuum lamp 8 with Spark Delay Valve 9, high-frequency igniter 11 usefulness leads are connected current distributor 10, the TJ Spark Delay Valve that Spark Delay Valve 9 selects for use Jingtu Industry Co., Ltd., Shanxi Prov. to produce, high-frequency igniter 11 are selected the triumphant WST high-frequency igniter that reaches Co., Ltd production of Yuci City for use.
2, change the main flow metering-orifice 7 of carburettor 5.
3, will connect exhaust gas reclrculation pipe 1 disconnection of exhaust branch pipe 13 and air intake branch 12, be connected with it with motorized valve 2; Motorized valve 2 is connected with lead with EUU electric controller 3 interfaces.HB2000 type motorized valve and EUU electric controller that motorized valve 2 and EUU electric controller 3 select for use beach, Beijing Electronics Co., Ltd. to produce.
4, catalytic convertor 14 is installed between exhaust branch pipe 13 and the noise silencer 15, device is changeed in the catalysis that catalytic convertor 14 selects for use Jingtu Industry Co., Ltd., Shanxi Prov. to produce.
The utility model is based on catalytic convertor, by the carburetor type automotive engine is taked above measure, improve engine power performance and fuel economy, and provide the good operation condition to catalytic convertor, make motor vehicle exhaust emission stable national specified discharge standard that reaches under various operating mode.
