Bruce Crower of Crower Cams has designed and patented a new six stroke gasoline engine that uses steam to produce a second power stroke that is produced from water injection.
This engine design is supposed to produce equal horsepower, but a 40% decrease in fuel consumption and a significant decrease in emissions.
Not sure if it has a cooling system
at all.
