Does anyone know what Smokey's hot vapor engine got for gas mileage?
That design has always been interesting to me as his intake manifold temp was 440F. The end point of vaporization for pump gas is/was 437F. What this means is the fuel was 100% vaporized before it got to the chamber. He remembered liquid fuel does not burn.
What Smokey improved was vaporization efficiency by using waste heat. He maintained mixture density with a turbo. The engine did not ping even though many tried.
What is the percentage of vaporization in today's fuel injected engines? 100%? What is the percentage of vaporization in a carbureted engine? 100%?
