Adapting high efficiency internal combustion engines to operate on a mixture of hydrogen and natural gas (HCNG) could result in cost effective power plants to assist with the transition to hydrogen based transportation. Previous studies have shown that HCNG fuel can reduce emissions of NOx (oxides of nitrogen) of a lean burn engine. If the hydrogen is obtained from a renewable source it can help reduce greenhouse gas emissions. This paper presents knowledge gained from engine combustion and emissions testing with three different fuels. A turbocharged lean burn spark ignition engine was operated on natural gas as well as mixtures of hydrogen and natural gas (20/80 and 30/70 H2/NG by volume%). The engine performance and emissions were recorded at several speed and load conditions. Test parameters included air/fuel ratio and the combustion timing. A response surface model was developed from the experimental data and used for predictive purposes. Results indicate that addition of hydrogen to natural gas fuel improves combustion at lean air/fuel ratios and extends the lean limit resulting in lower NOx and hydrocarbon emissions without sacrifice in engine torque or fuel economy.
