Disclosed herein is a two stroke fuel injection engine including a closed auxiliary cylinder extending from the head end of a main cylinder, together with an auxiliary piston which is movable in the auxiliary cylinder between an extended position adjacent to the main cylinder when the piston in the main cylinder is at bottom dead center and a retracted position remote from the head end of the main cylinder when the piston in the main cylinder is adjacent to top dead center position. Between the piston in the main cylinder and the auxiliary piston when in its retracted position, there is defined an initial or precombustion chamber which communicates with a fuel injection means and which is scavenged by movement therethrough of the auxiliary piston during travel from the retracted to the advanced position.
