ABSTRACT:
An injector system adapted for use in a free-piston engine, includes an injection pump designed in the form of a free-piston pump and having a pump piston accommodated in a cylinder for reciprocating within the cylinder for making a compression stroke from a bottom dead center to a top dead center and for making an expansion stroke from the top dead center to the bottom dead center, an injector nozzle disposed in an engine piston or in a cylinder head which oscillates axially together with the engine piston, for injecting fuel received from the injection pump into a working chamber of the free-piston engine, a stroke limiting piston bearing on a working chamber distant end of the pump piston, and a restriction mechanism for limiting the travel of the limiting piston and the travel of the pump piston in the directions of the compression stroke and the expansion stroke. The free piston pump is so installed in the engine piston or in the cylinder head that oscillates axially with the engine, that during the compression stroke, the pump piston travels towards the working space of the engine so that the pump piston is driven by forces as a result of its own mass inertia and forces of the mass inertia of the limiting piston.
