Experimental study of NOx and CO2 emissions at load regimes for a passenger car powered by direct injection diesel engine

摘要

The paper presents a study of NOX and CO2 emissions for a standard diesel direct injection engine,which equips the Renault-Dacia Solenza 1.9D-SDI cars.The different pollutions levels are analysed between idling regimes and medium and high loads at different speeds and transmission gearboxes.To simulate the load regimes,chassis dynamometer V-Tech Dyno VT-2/B1 was used.The exhaust gases were taken to various operating modes on the chassis dynamometer,specific regimes in urban and extra-urban mode.In the paper,some recommendations are made on operating regimes that would ensure the functioning of the car at a lower polluting level.
