We improved the system of a high-speed single-acting 4-stroke diesel engine to allow it run on a mixed fuel comprised of A-heavy oil and DME (Di-Methl Ether), fuel components that discharge no soot, no SOx, and little NOx in combustion. The combustion pressure, rate of heat release, exhaust gas components, and other conditions were measured in experiments using diesel oil, A-heavy oil, and the mixed fuel comprised of DME and A-heavy oil.As a result, the ignition timing was earliest with diesel oil, median with the mixed fuel, and latest with A-heavy oil. Mixed fuel discharged a slightly reduced level of NOx. Overall, results indicated that the engine would require further improvements before long-term operation became possible.
