This paper summarizes the validation testing of the Horiba Instruments OBS-2200 gaseous portable emissions measurement system (PEMS) for in-use compliance testing per Title 40 of the Code of Federal R....
Fuel consumption is already one of the parameters taken into account for the final ranking of some competitions organized by the Federation International de l'Automobile (FIA). Pollutant emissions, su....
The effect of biodiesel on the Particulate emissions is gaining significant attention particularly with the drive for the use of alternative fuels. The particulate matter (PM), especially having a dia....
New European emissions legislation (Euro5) specifies a limit for Particle Number (PN) emissions and therefore drives measurement of PN during vehicle development and homologation. Concurrently, the us....
Particulate matter (PM) emitted from light-duty gasoline powered vehicles is under increasing scrutiny due to potential adverse health effects and on ever increasing number of vehicles in the fleet. I....
The objectives of the present work are to investigate the regulated and unregulated (particle) emissions of a classical and modern 2-stroke and a typical 4-stroke scooter with different ethanol blend ....
Particulate Matter (PM) legislation for gasoline engines and the introduction of gasoline/ethanol blends, make it important to know the effect of fuel composition on PM emissions. Tests have been cond....
Concern for engine particle emission led to EC regulations of the number of solid particles emitted by LDV and HDV. However, all conventional piston-driven combustion engines emit metal oxide particle....
A detailed study is undertaken to examine how 2010+ diesel engine exhaust emissions change when a soybean-derived B20 biodiesel fuel is used instead of a conventional ultra-low sulfur diesel fuel and ....
Particle number emissions are measured with two instruments according to the upcoming European emission regulations for light-duty diesel passenger vehicles and compared to data from other methods, in....
Two Euro 4 light-duty diesel vehicles were retrofitted with Diesel Particulate Filters (DPF). One was retrofitted with a low efficiency flow-through DPF. And, the other was retrofitted with a high eff....
Effects of biodiesel fuel on nucleation mode particles were studied on a direct injection, high pressure common-rail diesel engine for passenger cars. Particle number and size distribution of the dies....
In light of forthcoming particle number legislation for light-duty passenger vehicles, time-resolved Particle Mass (PM) and Particle Number (PN) emissions over the New European Drive Cycle (NEDC) are ....
