Experimental Investigation on Improvement of Emission from Diesel Engine by Fueled with Methanol/diesel Blends

Abstract

As a kind of powered machine possess high heat efficiency and reliability, diesel engines have been widely used in the production of all aspects of life. However, with the gradually attention to the environmental problems, the emissions from diesel engines have been a large obstacle to constraining diesel engines development. This article attempts to study the correlative experiment on the emissions from diesel engines fueled with methanol/diesel blends and pure diesel oil, carrying out the conclusion that diesel engines fueled with methanol/diesel blends can effectively reduce the emissions of soot and NOx. Due to the physical and chemical characteristics of methanol, HC emissions have increased after diesel engines fueled with methanol/diesel blends, but it is under control. In general, the emission problem of diesel engines fueled with methanol/diesel blends have been generally improved.
