Abstract

The invention relates to a black carbon sampling system for a motor vehicle. The system comprises two diluter, an air filter and an air compressor, wherein the diluters are separately connected to theair filter in parallel and each of the diluters comprises an inlet pipe, an inner cavity and an outlet pipe; a compressed air pipeline is arranged on the inlet pipe, an exhaust gas exhausting pipeline is arranged on the outlet pipe, and a sampling system is arranged between the compressed air pipeline and the exhaust gas exhausting pipeline. The system provided by the invention is accurate to test, can analyze the test result conveniently, is simple in connecting structure and high in practicality, and can perform industrial production.

Description

technical field [0001] The invention relates to a black carbon sampling system for motor vehicles. Background technique [0002] Carbon aerosol is a serious hazard to the human body and the environment, and is also one of the main factors causing urban smog. Among the chemical components of atmospheric PM2.5, black carbon is the product of incomplete combustion of carbon-containing substances in fossil fuels. It is considered Significant impacts on climate change and human health. Atmospheric carbon aerosols generally include organic carbon and elemental carbon. The research on the basic properties of black carbon and its impact on climate, environment and health is becoming one of the hotspots in current international atmospheric chemistry research. The formation and effect of black carbon are complicated, and there are many uncertain factors. Black carbon is also a typical short-life cycle, the main substance that causes global climate change and produces smog, and is c...
