ABSTRACT:
A method for starting a free piston internal combustion engine that includes a first pair of mutually connected pistons, a second pair of mutually connected pistons, a first piston of each pair located in a first cylinder, a second piston of each pair located in a second cylinder. An air charge is supplied to a closed space in the cylinders, and the pistons are reciprocated to increase pressure of an air charge cyclically during successive cycles and to produce a predetermined pressure magnitude. Air and fuel are cyclically admitted to the first cylinder to produce repetitively a fuel-air mixture in the first cylinder. Cyclic combustion of the mixture in the first cylinder is produced, but a delay in applying to the engine at least a portion of an external load occurs until cyclic combustion of an air-fuel the mixture in the second cylinder occurs.
