Problems solved by technology

If the company adopts the GB14621-2002 national standard measurement method to test each motorcycle of the same model, it will take a long time due to the long warm-up time, which is not conducive to improving production efficiency
At present, there is no practical motorcycle idling emission measurement method that can quickly measure every motorcycle of the same model and make its measurement results consistent with those using national standards.

Abstract

The invention relates to a motorcycle emission measuring method which includes the steps: 1) selecting one motorcycle conforming to emission standards; 2) preheating the motorcycle according to GB14621-2002; 3) measuring a standard temperature field; 4) selecting one motorcycle to be measured; 5) performing rapid running and preheating; 6) performing idle preheating; 7) adjusting idle speed; 8) measuring the temperature field of the motorcycle to be measured, continuing a step 9 if the temperature field is inconsistent with the standard temperature field, and skipping to a step 11 if the temperature field is consistent with the standard temperature field; 9) completely cooling the motorcycle to be measured; 10) returning to the step 5 and adjusting running speed v; 11) measuring the idle speed according to the GB14621-2002; 12) performing numerical value rounding; 13) recording idle speed emission measuring results; 14) returning to the step 4, and measuring emission of a next motorcycle. The motorcycle can be rapidly measured, and accuracy of testing results can be ensured.

Description

technical field [0001] The invention relates to a motorcycle measurement method, in particular to a motorcycle emission measurement method. Background technique [0002] In order to protect the environment, the exhaust pollutants of motorcycles must be measured before leaving the factory, and only motorcycles that meet the emission standards can be put on the market. GB14621-2002 is the national standard on "Limits and Measurement Methods of Exhaust Pollutants from Motorcycles and Mopeds (Idling Speed ​​Method)", which stipulates the exhaust pollutants of motorcycles and mopeds under idling conditions. The measurement method of the same carbon (CO) and hydrocarbon (HC): [0003] 1) Start the vehicle and preheat the vehicle according to one of the following conditions: [0004] 1a) Motorcycles run at a speed of 50km / h and mopeds at a speed of 40km / h for 10km; [0005] 1b) Motorcycles shall be run on the chassis dynamometer for four cycles according to the working condition...
