Description
Technical field
The present invention relates to the technical field of vehicle exhaust test, it is specially a kind of simple and easy system for testing discharge of motor vehicle transient behavior method.
Background technology
Existing vehicle complete vehicle discharge detection system mainly comprises Chassis dynamometer machine, environmental simulation storehouse, emission test equipment, the big nucleus equipment of main control equipment four, its cost is more than 1,000 ten thousand yuans, it relates to auxiliary facilities such as distribution, cooling tower, refrigerated water, gas pipeline, pressurized air. Outside laboratory, also need to build leaching workshop, conductive flooring, smoke-exhaust pipeline etc.
Current domestic whole car disposal facilities, Chassis dynamometer machine, main control computer mostly are English operation system, and not only for Chinese law and regulations, also comprise the regulation of the different countries and regions such as Europe, the U.S., Japan in control computer. It is not only for emission testing, it is also possible to carry out environmental simulation test, performance test etc., respectively different equipment is set to need in process of the test, for the requirement height of testing staff.
In addition, existing whole car discharge detection system complicated operation, existing test set also needed vehicle to carry out pre-treatment, controls for the environmental influence tested before process of the test. Any different control condition all can have influence on emission result. Operator need regulation, vehicle calibration, engine to be had gained some understanding.
Current detection system, the reporting format of each equipment manufacturer is not unified, and reporting format is English. Report content can comprise some process datas, it is unfavorable for the unified supervision of environmental administration and the foundation of big data.
The environmental protection standard (GB/T18352) of current domestic new car certification, this test one circulation 1180 seconds, adds setup time, and doing single test probably needs 30 minutes, and vehicle cold starting requires static more than 6 hours of leaching workshop. It is unfavorable for carrying out on a large scale random checking, especially the popularization in in-use automotive market.
The domestic environmental protection standard (GB/T18285-2005) implemented for in-use automotive, has three kinds of testing method for in-use automotive in standard, Double idle state method, steady state condition method and transient behavior method.Current new car off-line test many employings Double idle state method. In-use automotive test house is except the regional applying working condition method that the vehicle guaranteeding organic quantities such as Beijing, Sichuan, area, Pearl River Delta, Yangtze River Delta Area are big, and whole nation most area still uses Double idle state method.
Two kinds of environmental protection tests standards do not have cognation, if result is declared in the discharge still adopting existing detection method cannot trace back to the new car certification of whole depot when environmental administration carries out spot-check supervision from now on.
When getting rid of artificial cheating, equipment cheating, the discharge detection method of in-use automotive is adopted also can not comprehensively to react vehicle emission behaviour at present. For the steady state condition method in Jiangsu Province, concrete reason mainly contains three aspects:
1, the discharge accuracy of detection of five gas analyzer is low. Observed value is concentration value, does not have corresponding relation with the g/km unit of regulation certification.
What adopt when 2, measuring is 25km/h and 40km/h two speed stabilizing operating modes, can not truly reflect the travel situations of vehicle in urban district. Especially the situation of the meeting considerable changes of exhaust contaminant quantity such as vehicle launch, acceleration, deceleration cannot be reflected.
3, Chassis dynamometer machine does not load, and only carrys out simulated roadway situation by increasing inertia, is equivalent to vehicle and dallies on roller. The situation of vehicle at road traveling can not be reflected really.
