Description
Technical field
The present invention relates to a kind of a kind of test method of motorcycle emission control.
Background technology
By the retrieval Chinese patent literature, still do not have similar test method at present, and the main core content of known matching test method is the circulation repeatedly of " adjusting match test → operating mode emission test/continuous sampling → qualified judgement → analysis continuous sampling data → adjustment match test ".
But,, the adjustment of carburetor is had certain rashness in action because operating mode emission test result and carburetor do not have definite one-to-one relationship between adjusting; And after adjusting match test, all must do operating mode emission test/continuous sampling at every turn, obtain emission test results after, can know just whether coupling reasonable; Therefore, whether coupling rationally exists certain uncertainty.Not only matching test method complexity, and the technical difficulty of coupling is big, the cycle of coupling is long, cost is higher.Usually need 10～15 talentes may the match is successful a vehicle.
Summary of the invention
In order to overcome the matching test method complexity that exists in the prior art, and the technical difficulty of coupling is bigger, and the cycle of coupling is longer, the more high defective of cost.The invention provides a kind of motorcycle emission control match test of having simplified, improved the success ratio and the efficient of match test, significantly reduced coupling technical difficulty, shortened coupling cycle, reduced the matching test method that is used for motorcycle emission control of the cost of match test.
The technical solution adopted for the present invention to solve the technical problems is: this matching test method that is used for motorcycle emission control, and it comprises the following steps: (1) former car performance, operating mode/idle exhaust emission test; (2) change the empty filter of coupling; (3) carburetor/catalyst sound suppressor/secondary air inlet coupling; (4) constant speed discharging standardization; (5), enter operating mode discharging validation test/continuous sampling if it reaches desired value; If its miss the mark value is returned step (3) again; (6) operating mode discharging validation test/continuous sampling; (7), enter coupling car performance, idle exhaust emission test if it is qualified; If it is defective, enter the analysis data, find out the direction of adjusting carburetor, return step (3) again; (8) coupling car performance, idle exhaust emission test; (9), finish match test if it is qualified; If it is defective, enter step (3) once more.
Constant speed discharging standardization is by carry out the test of constant speed emission performance with the idle exhaust emission analyser at each operating mode discharging constant speed point, throttle wide point and working condition tests circulation mean value on the car load stand; According to the discharging development goal, determine constant speed emission performance desired value; Only on the car load stand, mate adjustment then and reach this constant speed emission performance desired value, carry out the checking of operating mode emission testing repetition measurement at last again until constant speed emission performance trial value with the idle exhaust emission analyser.
Above-mentioned constant speed discharging standardization comprises the following steps: the test of (1) idle exhaust emission; (2) 1 retaining 15km/h emission tests; (3) 2 retaining 32km/h emission tests; (4) 3 retaining 50km/h emission tests; (5) the top gear emission test that gives full throttle; (6) 3 retaining 50km/h emission tests; (7) 2 retaining 35km/h emission tests; (8) 1 retaining 15km/h emission tests; (9) idle exhaust emission test; (10) working condition tests circulation mean value emission test; (11) test value and desired value are relatively.
The main core content of this method is the cycle stage repeatedly of " adjusting coupling → constant speed discharging standardization ".
Between constant speed discharging calibration characteristic trial value and the carburetor adjustment very strong relevance is arranged, be easy to determine to adjust the direction of carburetor, thereby reduced the difficulty of technology coupling greatly; Match test only need use the idle exhaust emission analyser to carry out on the car load stand, and the match test process is simply rapid, and test findings is concisely directly perceived; After treating that the test of constant speed discharging calibration characteristic reaches constant speed emission performance desired value, carry out the checking of operating mode emission testing repetition measurement again.Usually only need 3～5 days can the match is successful a vehicle.

Fig. 2 is the process flow diagram of constant speed that the embodiment of the invention adopts discharging standardization.
Embodiment
To be further described the specific embodiment of the present invention in conjunction with the accompanying drawings:
Referring to Fig. 1, a kind of matching test method that is used for motorcycle emission control, it comprises the following steps: (1) former car performance, operating mode/idle exhaust emission test; (2) change the empty filter of coupling; (3) carburetor/catalyst sound suppressor/secondary air inlet coupling; (4) constant speed discharging standardization; (5), enter operating mode discharging validation test/continuous sampling if it reaches desired value; If its miss the mark value is returned step (3) again; (6) operating mode discharging validation test/continuous sampling; (7), enter coupling car performance, idle exhaust emission test if it is qualified; If it is defective, enter the analysis data, find out the direction of adjusting carburetor, return step (3) again; (8) coupling car performance, idle exhaust emission test; (9), finish match test if it is qualified; If it is defective, enter step (3) once more.
Fig. 1 as can be known, the main core content of the present invention is the cycle stage repeatedly of " adjusting coupling → constant speed discharging standardization → desired value judgement → adjustment mates ".Working contents is to carry out " constant speed discharging standardization " and " adjusting coupling " with the idle exhaust emission analyser on the car load stand; Reach this constant speed emission performance desired value until constant speed emission performance trial value, carry out the checking of operating mode emission testing repetition measurement at last again.
Constant speed discharging standardization is to carry out the test of constant speed emission performance with the idle exhaust emission analyser at each operating mode discharging constant speed point, throttle wide point and working condition tests circulation mean value on the car load stand; According to the discharging development goal, determine constant speed emission performance desired value; Only on the car load stand, mate adjustment then and reach this constant speed emission performance desired value, carry out the checking of operating mode emission testing repetition measurement at last again until constant speed emission performance trial value with the idle exhaust emission analyser.
Referring to Fig. 2, described constant speed discharging standardization comprises the following steps: the test of (1) idle exhaust emission; (2) 1 retaining 15km/h emission tests; (3) 2 retaining 32km/h emission tests; (4) 3 retaining 50km/h emission tests; (5) the top gear emission test that gives full throttle; (6) 3 retaining 50km/h emission tests; (7) 2 retaining 35km/h emission tests; (8) 1 retaining 15km/h emission tests; (9) idle exhaust emission test; (10) working condition tests circulation mean value emission test; (11) test value and desired value are relatively.
As shown in Figure 2, owing between constant speed discharging calibration characteristic trial value and " adjusting coupling " very strong relevance is arranged, have stronger directiveness to adjusting matching scheme, adjust the quality of matching scheme and can on the car load stand, verify immediately by the constant speed emission performance desired value of " constant speed discharging standardization "; Whole match test process is simply rapid, and test findings is concisely directly perceived; Thereby can improve the success ratio of match test, the remarkable technical difficulty of coupling, the cycle that shortens coupling, the reduction match test cost of reducing.
