Particle Number Emissions During Regeneration of DPF-equipped Light Duty Diesel Vehicles A Literature Survey
The study reviews published work on the particle emissions during regeneration of diesel particulate filters in anattempt to assess the PMP methodology under these operating conditions. During regeneration of the DPF asignificant increase of the emitted number of particles is observed. Size spectra reveal a nucleation modepeaking at approximately 10 nm, at concentrations that ca...
متن کامل[Emission of aldehydes from light duty diesel vehicles].
OBJECTIVE To characterize acetaldehyde and formaldehyde emissions, which are harmful gases to human health and not yet regulated for diesel engines. METHODS Standardized tests were performed in four diesel light duty commercial vehicles, using a frame dynamometer and test procedure FTP-75. The pollutants were analyzed by high performance liquid chromatography. RESULTS Results have shown ace...
متن کاملEffects of biodiesel blends and Arco EC-diesel on emissions from light heavy-duty diesel vehicles.
Chassis dynamometer tests were performed on seven light heavy-duty diesel trucks comparing the emissions of a California diesel fuel with emissions from four other fuels: ARCO emissions control diesel (EC-D) and three 20% biodiesel blends (one yellow grease and two soy-based). The EC-D and the yellow grease biodiesel blend both showed significant reductions in total hydrocarbons (THC) and carbo...
متن کاملComparison of particle mass and solid particle number (SPN) emissions from a heavy-duty diesel vehicle under on-road driving conditions and a standard testing cycle.
It is important to understand the differences between emissions from standard laboratory testing cycles and those from actual on-road driving conditions, especially for solid particle number (SPN) emissions now being regulated in Europe. This study compared particle mass and SPN emissions from a heavy-duty diesel vehicle operating over the urban dynamometer driving schedule (UDDS) and actual on...
متن کاملPCDD/F emissions from light-duty diesel vehicles operated under highway conditions and a diesel-engine based power generator.
PCDD/F emissions from three light-duty diesel vehicles--two vans and a passenger car--have been measured in on-road conditions. We propose a new methodology for small vehicles: a sample of exhaust gas is collected by means of equipment based on United States Environmental Protection Agency (U.S. EPA) method 23 A for stationary stack emissions. The concentrations of O2, CO, CO2, NO, NO2 and SO2 ...
