Abstract: A spark-ignited (SI) internal combustion (IC) engine designed to operate on high octane fuels, such as gasoline, is reconfigured to operate on low octane fuels including logistically preferred distillate fuels, such as diesel or JP-8. Design modifications involve coupling a fuel reformer module to the internal combustion engine. Auxiliary components include a system control module, a heat exchange module, a bypass valve to facilitate start-up, and/or a throttle body to control a reformate-oxidizer mixture fed to the engine. Small portable generators having 0.3-3.0 kWe power output are disclosed based upon the modified SI-IC engine design.

Abstract: An apparatus and method for operating a gas-fired burner on a liquid fuel. The apparatus integrates a catalytic liquid fuel reformer with a flame burner designed for operation on a gaseous fuel of high Wobbe Index, e.g., natural gas. The method involves reacting a mixture of a liquid fuel and oxidant in a catalytic reformer to obtain a gaseous reformate having a low Wobbe Index; and thereafter combusting the gaseous reformate, optionally augmented with liquid co-fuel and oxidant, in the gas-fired burner under diffusion flame conditions. The invention allows commercial gas-fired appliances, such as stoves, ovens, ranges, grills, griddles, stock pot burners, clothes dryers, hot water heaters, and boilers to be operated on a liquid fuel, which offers advantages in logistics and camp operations.

Abstract: A gas-fired burner adapted for use on a liquid fuel. A method for essentially smokeless start-up and steady state operation of a gas-fired burner on a liquid fuel. The apparatus integrates a catalytic liquid fuel reformer with a flame burner designed for operation on a gaseous fuel of high Wobbe Index, e.g., natural gas. The method involves reacting a mixture of a liquid fuel and oxidant in a catalytic reformer to obtain a gaseous reformate having a low Wobbe Index; and thereafter combusting the gaseous reformate, optionally augmented with liquid co-fuel and oxidant, in the gas-fired burner under diffusion flame conditions. The invention allows commercial gas-fired appliances to be operated on a liquid fuel, thereby offering advantages in logistics and camp operations.
