Study of the combustion characteristics of the dual-fuel diesel engine
This research analyzes the combustion characteristics of dual-fueled diesel engines. A medium-displacement high-speed engine type is used in the experimental work. Research efforts have concentrated on the combustion characteristics of the larger, lower-speed engines primarily designed for dual-fuel operation. Also, effects have produced certain engine conversions in the medium size high-speed range. The combustion theory of these engines is applied, developed, and expanded to fit high-speed medium-sized, direct-injected engines. Two engines are used in this study: a 3208 Caterpillar V-8 that is naturally aspirated and a 4307 Caterpillar in-line six-cylinder that is turbocharged and intercooled. The experimental work for this study is devoted to the application of a retrofit methane system to fumigate methane into the intake of a diesel engine. The mixture is ignited with a pilot charge of diesel fuel injected into the cylinder by the engine's fuel injection system the fuel-air ratio at the point of optimum combustion exemplifies proportions designed to insure similar performances as the original diesel engine. Systematic experimentation designed to collect data such as performance, emissions, and specific fuel consumption indicates. The maximum combustion efficiency. Through theory and experimental evidence. This study provides the necessary information to assure complete, controlled dual-fuel combustion in medium-sized, high-speed diesels.
