ABSTRACT:
A fluid piston engine with a plurality of cylinders wherein the plurality of cylinders are daisy chained through a single turbine having a single impeller. The fluid piston engine has a plurality of daisy chained cylinders that burn a fuel of hydrogen, and an oxidizer of air, preferably oxygen. A method of operating a fluid piston engine with a plurality of daisy chained cylinders includes steps where the operating controls are triggered by a fluid level sensor in a cylinder. Rather than from the cylinder, combustion byproducts are exhausted through a relief valve on an accumulator. Engine performance is varied by selectively idling cylinders and by varying the relative timing of multiple pairs of cylinders, wherein each pair uses internal combustion to expel fluid out of a first cylinder, through the turbine and into the second cylinder of the pair in which the combustion gases are compressed by the circulating fluid piston.
