Description
Technical field
The utility model relates to a kind of detection device of Motorcycle Catalystic Converter.
Background technique
Because the recoverable amount of motorcycle is increasing, it is more and more higher to environmental requirement that regulation is arranged by motorcycle national Ⅲ emission regulation and the state IV being about to perform, catalytic converter has become the essential core parts of emission control and has used in a large number on motorcycle, and the transformation efficiency of catalytic converter directly has influence on the discharge quality of motorcycle exhaust.
The catalytic converter transformation efficiency detecting method that now most domestic motor enterprise adopts at present is: adopt manual simulation's motorcycle exhaust composition, by the catalyst converter sample of cutting after heating, carries out gas concentration contrast before and after catalytic converter.Its shortcoming is:
1. system architecture is more complicated, and need special detection facility, testing cost is higher;
2. analog gas is for reasons such as technology, cost and safety, causes and there is larger difference at flow in composition method and real motorcycle tail gas, thus produce larger test error;
3. can not test whole catalytic converter, test process need cut into sample exemplar, and cutting process can cause catalytic converter coating shedding, affects test result.Test process causes test sample to destroy, the quality control of unfavorable small lot catalytic converter.
Model utility content
The purpose of this utility model is to provide a kind of Motorcycle Catalystic Converter testing apparatus not destroying catalytic converter body and can carry out testing.
To achieve these goals, by the following technical solutions: a kind of Motorcycle Catalystic Converter testing apparatus, it is characterized in that: described device comprises the linear oxygen sensors be arranged on motorcycle exhaust pipe, the data that electric spray control system is collected by linear oxygen sensors adjust fuel injection system, thus the air fuel ratio of adjustment combustion gas, the afterbody of motorcycle exhaust pipe is also provided with catalytic converter successively, also air collecting pipe is separately installed with on the motorcycle exhaust pipe of catalytic converter front portion and on the pipeline of catalytic converter rear portion outlet, the outlet of two air collecting pipes is connected on two gas inlets of emission analyzer respectively.
The rear portion of described catalytic converter is also provided with baffler.
The utility model can realize catalyst converter and directly test in motorcycle exhaust, closer to Environmental Conditions; Accurately can control air fuel ratio, the transformation efficiency of testing catalytic converter under different air fuel ratio condition; Non-destructive test exemplar, tests catalytic converter monolith; Do not use high concentration harmful gas to carry out distribution, reduce test safety risk and testing cost; Whole process of the test is simple, accurate and effective, convenient operation, and the test that can realize various Motorcycle Catalystic Converter transformation efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is fuel injection system, and 2 is motor, and 3 is linear oxygen sensors, and 4 is temperature transducer, and 5 is catalytic converter, and 6 is baffler, and 7 is emission analyzer, and 8 is electric injection system control software design, and 9 is ECU.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
One, make one and demolition can be installed by the silencing apparatus 6 of catalytic converter, for installation testing exemplar, linear oxygen sensors 3, temperature transducer 4, before and after catalytic converter 5, install gas sampler additional; The difference of this baffler and common silencing apparatus is that the catalytic converter mounting type of common silencing apparatus changes removable manner into by the mode that can not change, and weld lambda sensor, temperature transducer installation stand, welding gas sampling pipe interface before and after catalytic converter position.
1, motorcycle engine adopts electric spray control system, and linear oxygen sensors 3 is to realize linearly adjust and the monitoring of air fuel ratio;
2, motor runs on cruising mode, utilizes electric injection system control software design 8 adjusting air-fuel ratio to desired value;
3, after the exhaust temperature of monitoring catalytic converter 5 is extremely stablized, the pipe sampling of adopting before and after catalytic converter carries out concentration analysis to emission analyzer, calculates transformation efficiency finally by change in concentration before and after catalytic converter.
Catalytic converter transformation efficiency test method object is: 1. realize not destroying catalytic converter body carry out test 2. directly use motorcycle exhaust carry out test 3. realize different air fuel ratio condition under test.
The utility model installs linear oxygen sensors additional by motorcycle electric spraying control system, accurately can control motor under different air fuel ratios, burn (traditional motorcycle electric spraying system can only control motor and burn near 1 at excess air coefficient).When run by constant speed on chassis dynamometer for motorcycle, be fixed value by EFI calibration software setting air fuel ratio, accurately tested by linear oxygen sensors and feed back air fuel ratio information, make system revise fuel injection quantity further and realize accurate empty so than control.Thus provide source of the gas to test catalytic converter, then utilize tail gas change in concentration before and after emission analyzer testing catalytic converter.Feature is the combination of motorcycle and emission test instrument, and it focuses on the linearity control realizing air fuel ratio.
Claims (2)
1. a Motorcycle Catalystic Converter testing apparatus, it is characterized in that: described device comprises the linear oxygen sensors be arranged on motorcycle exhaust pipe, the data that electric spray control system is collected by linear oxygen sensors adjust fuel injection system, thus the air fuel ratio of adjustment combustion gas, the afterbody of motorcycle exhaust pipe is also provided with catalytic converter successively, also air collecting pipe is separately installed with on the motorcycle exhaust pipe of catalytic converter front portion and on the pipeline of catalytic converter rear portion outlet, the outlet of two air collecting pipes is connected on two gas inlets of emission analyzer respectively.
