Abstract
The efficiency of a spark-ignition internal-combustion engine having an adjustable fuel-to-air mixture ratio is improved significantly by reducing the fuel-to-air mixture ratio and increasing compression ratio. The increase in compression ratio and the reduction in fuel-to-air mixture ratio causes the engine to operate at higher efficiency and with lower air pollution levels, and without detrimental engine knock or misfire.
