Abstract
In a glow-assisted methanol diesel engine, combustion at low loads can be improved by using a slit injection nozzle. At high speeds and high loads, however, combustion dateriorates by the use of this type nozzle, because air entrainment into the spray is necessary to be insufficient. Thus, in this work, engine tests were conducted with combining EGR turbocharging by the use of a slit injection nozzle on the purpose of recovery of exhaust gas energy and promotion of air entrainment into the fuel spray. The results indicated that both engine performance and exhaust gas missions were improved simultaneously over the wide range of operating conditions.
