Variation and Control of Small Gasoline Engine Emissions Performance in the Plateau Region

Abstract:

When small gasoline engines using carburettor are operated in the plateau region, the air intake and fuel supply have different decrease with the altitude increase, and the mixture thicken and the emissions increase. Take outboard marine gasoline engine F15 as an example, the quantitative relationship comparing engines operated on the plateau region to on the plain in same mixing ratio are shown, which includes the power, specific fuel consumption, and CO, HC, NOx specific emissions. And fuel system correction methods are come out to meet EPA emission regulations in different altitudes.
