1. An internal combustion engine including:
at least one cylinder, a piston connected with a crankshaft and reciprocally movable within the at least one cylinder to define a power chamber therein, an intake valve configured to control a supply of fresh air into the power chamber, an exhaust valve configured to control a discharge of exhaust gas from the power chamber, wherein the internal combustion engine is configured such that a combustible fuel/air mixture located in the power chamber combusts during a power stroke and drives the piston in a direction of movement from a top dead center (TDC) to a bottom dead center (BDC) to rotationally drive the crankshaft, an ancillary chamber connected with the power chamber via a flow-through valve, an auxiliary piston reciprocally movable within the ancillary chamber, at least one fuel supply valve configured to supply liquid fuel or gaseous fuel into the ancillary chamber, an apparatus configured to actuate the flow-through valve and the fuel supply valve and to move the auxiliary piston such that: no fresh air from the power chamber goes into the ancillary chamber and by moving the auxiliary piston, liquid fuel, after vaporization in the ancillary chamber, or gaseous fuel is expelled from the ancillary chamber and injected into the power chamber to form the combustible fuel/air mixture in the power chamber. |
