Effects Of Air-Fuel Ratio And Operating Conditions On Particle Emissions From A Small Diesel Engine, 2018 Bucknell University
Effects Of Air-Fuel Ratio And Operating Conditions On Particle Emissions From A Small Diesel Engine, Odinmma John-Paul Ofili
Automotive engineers typically increase the air-fuel ratio (AFR) of an engine to control the amount of smoke emitted, but it not quite known how this process affects particulate number (PN). In the work presented, AFR was independently varied to study its effects on PN. It was found that increasing the AFR reduced the concentrations of larger particles from 108 #/cm3 to 106 #/cm3 which is an effect observable as a reduction in smoke. However, the same increases in AFR only resulted in an energy specific PN change from 1015 #/kWh to 1014 #/kWh. The ...

All Theses, Dissertations, and Other Capstone Projects
Throughout the evolution of high performance racing, a large emphasis has been on reducing the weight of the vehicle in order to improve its performance. Over the years, new designs and materials have been introduced reducing weight in a variety of different locations. Comparing weight reduced in different areas has shown that some areas are more valuable to reduce than others are. Perhaps one of the most beneficial locations are the wheels. This is because the mass of the wheel is considered unsprung and rotational. Because of this, large improvements towards the reduction of wheel mass have been developed in ...
