乳化燃料使用ディーゼル機関の燃焼変動に及ぼす水比率の影響 Influence of Water Content Ratio on Combustion Fluctuation of Diesel Engine Using Emulsified Fuel
The application of water-in-oil type emulsified fuel to marine diesel engines is one of the attractive methods from a viewpoint of NOx reduction. Considering with actual application, it must be known how the water content and environment temperature influence the stability of combustion and engine performance. However, the combustion stability of diesel engine operated with emulsified fuel have not been reported. Therefore, the authors examined the influences of water content ratio (water to gas oil ratio : Gw= 0 -1.19mass) and inlet air temperature (25- 6°C) on the stability of combustion.<BR>As a result, the sufficient combustion stability was obtained when the engine was operated under the conditions with higher load ratios than 1/4 (BMEP=0.26MPa) and lower water ratios than Gw=0.51.
