Test results from many researchers show that NOx emissions from parts of on-road heavy-duty diesels are higher than which been registered. Therefore, CN_VI emission regulations clearly proposes that the heavy-duty diesels should be supervised by a T-BOX which can transmit CAN message from vehicle OBD interface to the remote monitoring platform. Recognition of cheating behaver and calculation method of NOx emission were developed and verified by platform data from on-line vehicle. The modules in the platform can effectively monitor urea consumption rationality, injection system working state, exhaust temperature sensor signal reasonability, NOx sensor signal reasonability and NOx emission level, which can reduce the cost of supervision and governance, improve the effectiveness of regulation and provide basic data for policy making.
Key words: OBD / remote monitoring / platform / diagnosis / emission
