At UCR Engine; Cummins L9N Fuel; natural gas with hydrogen mix Scope of work; remove cylinder head, machine and install two sensors to read cylinder head pressure, re install cylinder head. The objective of the proposed work is to evaluate the impact of hydrogen content in natural gas on the performance and durability of one end use technology, specifically the Cummins L9N 8.9 liter near-zero natural gas engine. Cummins has a set limit for hydrogen content of 0.03% by volume, a long-standing limit probably set based on typical natural gas composition. Since the limit is part of the Cummins specification, using natural gas with hydrogen content greater than 0.03% could void the warranty of the engine. The proposed work will provide data that could justify the initiation of extensive validation work to increase the hydrogen limit in the Cummins Fuel Standard up to 5% in this study The proposed work will also provide valuable scientific information to South Coast Air Quality Management District (SCAQMD) on the actual engine performance and emissions from current ultra-low N Ox natural gas engines operated on hydrogen blends. While increasing the amount of low carbon alternative fuels in the natural gas pipeline will be of benefit to SCAQMD, this study will identify potential emissions pros and cons of using hydrogen fuels. Our results will help SCAQMD to better understand how the introduction of new fuels in the heavy-duty sector will affect GHG emissions, N Ox emissions.
