Modifying a 1971 Toyota Engine for the 1973 Reduced Emission Devices Rally

This paper describes the Oregon Institute of Technology's entry in the 1973 Reduced Emission Devices Rally held in California, one which won first prize for class 2 vehicles. The vehicle was a 1961 Anglia with a redesigned 1971 Toyota internal combustion engine. The engine was converted to use liquefied petroleum gas. The wiring was changed from d-c to a-c because it offered longer spark duration and a turbocharger was added to the LPG fuel system. The modifications resulted particularly in lower carbon monoxide emissions. Details of the vehicle are described.
