RISA New Criterion for Judging SI Engine In-Cylinder Pressure Development for Its Effect on Combustion Noise
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of engine in-cylinder pressure development on combustion noise is studied based on measured pressure traces and the attenuation-curve theory by Austen and Priede (1958). A new criterion ...
Liquid Fuel Impingement on In-Cylinder Surfaces as a Source of Hydrocarbon Emissions From Direct Injection Gasoline Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydrocarbon (HC) emissions from direct injection gasoline (DIG) engines are significantly higher than those from comparable port fuel injected engines, especially when “late” direct injection ...
