ABSTRACT:
An internal combustion piston engine for operation with gaseous and/or liquid fuel comprises at least first and second working cylinders associated with each other, with their working pistons movable in opposite relationship, and a fuel supply system which is operable to compress the fuel and which for each working cylinder has a piston compressor associated therewith at the cylinder head end. Each compressor has a cylinder and a differential piston axially movably accommodated in the compressor cylinder. The larger surface of the differential piston is subjected to the pressure in the combustion chamber of the associated working cylinder while the smaller surface of the differential piston is operable to compress the fuel when the pressure rises in the working cylinder combustion chamber. Extending between the compression chamber of the piston compressor and the combustion chamber of the associated working cylinder is at least one flow transfer path which has an opening into the combustion chamber, the opening being disposed in the path of movement of the differential piston and being adapted to be opened and closed by a control edge thereof. The differential pistons of the associated compressors are positively coupled in opposite relationship.
