Vehicle-mounted remote emission energy consumption measuring system and method for portable heavy diesel vehicle

Abstract

The invention provides a vehicle-mounted remote emission energy consumption measuring system and method for a portable heavy diesel vehicle, the system comprises a measurement host, a sensor group used for measuring tail gas of a vehicle to be measured, and a wireless communication module used for sending measured data to a monitoring platform, and the wireless communication module and the sensor group are both connected with the measurement host; the measurement host, the sensor group and the wireless communication module are all installed on a to-be-measured vehicle. According to the portable vehicle-mounted remote emission energy consumption measuring system and method for the heavy diesel vehicle, PM and NOx emission and oil consumption factors of the heavy diesel vehicle under the actual road working condition can be efficiently, accurately and conveniently obtained, and the defects that a PEMS is large in weight / size, difficult to arrange, complex to install, high in testing cost, long in testing period and the like are overcome.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle emission energy consumption measurement, and in particular relates to a portable heavy-duty diesel vehicle vehicle-mounted remote emission energy consumption measurement system and method. Background technique [0002] According to the "China Motor Vehicle Environmental Management Annual Report (2018)" data released by the Ministry of Ecology and Environment, the number of diesel vehicles in the country is 19.567 million, accounting for 9.4% of the number of vehicles, but the nitrogen oxides and particulate matter emissions from them account for 68.3% and more than 99% of the total emissions, so heavy-duty diesel vehicle particulate matter (PM) and nitrogen oxides (NOx) are the main sources of motor vehicle emissions and are the main objects of detection and supervision. [0003] Emissions and fuel consumption are important indicators for evaluating the energy-saving and emission-reduction p...
