Crower (of Crower Cams) has just patented a new "six stroke" engine design. The crank turns 3 times for each single cam revolution. The extra two piston strokes are after the normal exhaust stroke, and involve water direct injection into a closed cylinder. This flashes into steam, and produces a second power stroke. The exhaust then opens to vent the steam. Enough heat is drawn off by this steam production that no actual cooling system is required.
It's claimed this can improve fuel economy by as much as 40%. He's got a single-cylinder spark-ignition prototype working, and is now working on a compression-ignition version. |
