Advanced Hydrogen Utilization Technology Demonstration

    Research output: NRELTechnical Report


    This report presents the results of a study done by Detroit Diesel Corporation (DOC). DOC used a 6V-92TA engine for experiments with hydrogen fuel. The engine was first baseline tested using methanol fuel and methanol unit injectors. One cylinder of the engine was converted to operate on hydrogen fuel, and methanol fueled the remaining five cylinders. This early testing with only onehydrogen-fueled cylinder was conducted to determine the operating parameters that would later be implemented for multi cylinder hydrogen operation. Researchers then operated three cylinders of the engine on hydrogen fuel to verify single cylinder idle tests. Once it was determined that the engine would operate well at idle, the engine was modified to operate with all six cylinders fueled withhydrogen. Six-cylinder operation on hydrogen provided an opportunity to verify previous test results and to more accurately determine the performance, thermal efficiency, and emissions of the engine.
