The Scuderi Engine gains a massive advantage from turbocharging, Miller-like valve control strategies and extended expansion that is simply not possible with conventional engine designs.
Consistent with conventional four-stroke engine designs, the combustion cycle of the Scuderi Engine has two high-pressure strokes—compression and power. The power stroke is positive work, or energy that is produced by the expanding gases to create mechanical work. The compression stroke is negative work, or energy that the engine consumes to create mechanical work.
The useful work produced by the engine, the engine's output, is the difference between the positive work produced by the power stroke and the negative work consumed during the cycle.
By separating the compression cyclinder from the power cylinder, the size of the compression cylinder can be reduced to eliminate some of the negative compression work and, by incorporating a turbocharger into the engine's design, exhaust gas-energy can be recovered to achieve substantial reductions in negative work.
