Time-resolved particle emission and size distribution characteristics during dynamic engine operation conditions with ethanol-blended fuels

The effect of ethanol-blended gasoline fuels on the characteristics of time-resolved particle concentration and size distribution was investigated in a gasoline engine and in a flexible fuel vehicle. Particle concentration levels from the vehicle running on ethanol-blended gasoline were compared to those of diesel vehicles with and without diesel particulate filter (DPF). In the engine test, particle size distribution and number concentration using E0 and E10 fuels were analyzed with a differential mobility spectrometer (DMS500) at dynamic engine operation conditions. In the vehicle emission test, time-resolved particle concentrations with ethanol blending contents (E0, E10, and E85) during a new European driving cycle (NEDC) were analyzed with a golden particle measurement system (GPMS) as recommended by the particle measurement programme (PMP). As the excess air ratio is shifted to lean conditions and as the spark and intake valve opening timing are retarded, particle number levels were reduced with both E0 and E10. The particle concentration from ethanol-blended gasoline was slightly decreased regardless of engine operating conditions. From the driving test results, the total particle concentration from the spark ignition and the diesel vehicle with a DPF was decreased by two orders of magnitude compared to a non-DPF diesel vehicle. As the oxygenated component is increased, particle emissions decreased. The total particle concentration for E85 was reduced by 37% compared to E0.     

Experimental investigation of nanoparticle formation characteristics from advanced gasoline and diesel fueled light duty vehicles under different certification driving modes

This paper mainly focused on the comparison of nanoparticle size distribution and number concentration level characteristics with gasoline and diesel fueled light duty vehicles. In the engine research, particle size distribution and number concentrations were analyzed by a DMS500 with engine parameters. Time-resolved particle number concentration levels from test vehicles were measured by a golden particle measurement system (GPMS) as recommended by a Particle Measurement Programme (PMP) on certification modes such as New European Driving Cycle (NEDC), Federal Test Procedure (FTP)-75, and Highway Fuel Economy Test (HWFET). In addition, particle emission characteristics from vehicles were analyzed by DMS500 during transient and high-speed driving conditions. From the results, we found that the formation of particles was highly dependent on vehicle speed and load conditions for each mode. The diesel vehicle equipped with a particulate filter showed substantial reduction of the total particle number whose number concentration was equivalent to that of the gasoline vehicle. The nucleation mode particles from gasoline fuel were mainly emitted; however, the accumulation mode particles from the diesel fuel were generally analyzed.
