Abstract

In response to the increasingly stringent diesel emission regulations, the paper analyzes the relationship of the low-speed marine diesel engine's emission with the combustion process, the fuel injection law, the exhaust recirculation and the SCR. Then the scheme of the fuel injection system with the high-pressure common rail for the low-speed diesel engine is proposed, and the test system for the diesel engine's emission performance is established. Through the experimental research, the optimization and matching technology for the diesel combustion process based on the emission control is analyzed, and the best injection law of the diesel engine is revealed under the different conditions. That will provide the technical support for the design and operating management of the diesel engine.
