Abstract

The present invention discloses a detection system used for an engine emission control system. The detection system comprises an OBD data acquisition system and an APP system which are in signal connection via a wireless communication module A and a wireless communication module B, the OBD data acquisition system comprises a CAN wire data interaction module and a K wire data interaction module which are both connected with the wireless communication modules, and the APP system comprises a data interaction module, a vehicle information management module, an offline database management module, an emission control system matching module, a data stream analysis module and a logical judgment module. According to the detection system used for the engine emission control system provided by the present invention, aiming at different emission processing systems, and by a logical judgment method, whether the vehicles have the emission cheat means is inspected, thereby realizing an effective method of relieving the current air pollution condition.

Description

technical field [0001] The invention relates to the technical field of vehicle system inspection, in particular to a detection system for an engine emission control system. Background technique [0002] The "China Motor Vehicle Environmental Management Annual Report (2017)" recently released by the Ministry of Environmental Protection shows that my country has become the world's largest motor vehicle production and sales country for eight consecutive years, and motor vehicle exhaust pollution has become an important source of air pollution in my country. An important cause of photochemical smog pollution, the urgency of pollution prevention and control is highlighted. [0003] Classified by vehicle type, the emissions of nitrogen oxides and particulate matter from trucks are significantly higher than those from passenger cars, of which heavy-duty trucks are the main contributors; while the emissions of carbon monoxide and hydrocarbons from passenger cars are significantly hig...
