The California steam bus project was undertaken to evaluate the technical feasibility and public acceptance of the external combustion engine (ECE) as a low-emission, quiet propulsion system, using city buses as demonstration vehicles. Emphasis was placed on the early demonstration of potential, rather than extensive development or technical perfection. The title 'steam bus' was adopted after the choice of Rankine cycle systems to exemplify the ECE. Steam propulsion systems were installed in three 40-foot transit coaches, replacing the original diesel engines. The buses were tested and demonstrated in the metropolitan areas of Oakland, San Francisco, and Los Angeles. The report presents findings on performance, emissions, noise, fuel consumption, operating characteristics, revenue service, and potential for fuel consumption and emissions improvement.
