The goal of this project is to demonstrate the feasibility of retrofitting a diesel engine for catalytic operation, to study the operation of the engine during a 200-hour durability test. Pressure-volume data, oil analysis, and scanning electron photographs will also be obtained at regular intervals to document changes in catalytic surface activity. Aqualytic Technologies, Inc., modifies 20 hp Yanmar engine to burn ethanol-water fuel, installs manifold fuel injection, and designs catalytic igniters. This testing will involve cycling between part load, full load, and idle. Graduate student collects data on engine performance throughout the EMA test including power output, fuel consumption, in-cylinder pressure data, oil analysis, and catalyst surface characterization.
Graduate student develops a model to assist with sizing and timing catalytic igniters.
Principal investigators write at least two proposals to obtain additional funding. Catalytic ignition research will perform surface characterization and develop applications for integration onto test platforms. The purpose of these research projects is to generate a base of experimental and analytical data that can be used to support the implementation of new low-emission engine concepts on integration platforms. These concepts, in turn, will be validated in extensive on-road testing and comprehensive performance and emissions testing at the Idaho National Engineering and Environmental Laboratory. A variety of research, technology transfer, and technology demonstration opportunities will be pursued to continue the proposed research.
