techniques, (such as partial oxidation or autothermal reforming). Fuel reforming involves energy losses and the hydrogen concentration and reforming efficiency varies depending on the base fuel, reforming technique and reformer operating parameters. However, the energy loss involved in reforming a base fuel might be offset by improvements in engine operating efficiency achievablewith reformer gas blending.This paper reports on an experimental study where reformer gas with fixed mixture composition was used to enhance EGR tolerance limit of a natural gas engine to achieve extremely low NOx and high efficiency while keeping the mixture at stoichiometric air/fuel ratio enabling use of a regular 3-way NOx catalytic converter.
