N2 - This paper deals with exhaust gas emission characteristics in a glow-assisted DI engine fueled with methanol. The engine used was a 3.64-litter, four-cylinder, water-cooled, four-stroke-cycle, diesel engine manufactured for medium duty trucks. The experiments were carried out to investigate the influence of the condition of intake air on exhaust emission characteristics. The results indicate that intake throttling can favorably reduce NOx, formaldehyde and unburned methanol emission and improve thermal efficiency. Intake heating can reduced formaldehyde and unburned methanol emission and improved thermal efficiency but increase NOx emission. EGR can reduce NOx and unburned methanol emission and improve thermal efficiency but increase formaldehyde emisison.
