Abstract: A two-stroke reciprocating piston engine is configured with a cylinder 12 having a cylinder head 16. A piston 18 is mounted in a bore of the cylinder for reciprocating motion. A symmetrically shaped combustion chamber 24 is defined by a crown of the piston at top dead center and the cylinder head. At least two valved inlet ports 26 having orifices 28 positioned in the cylinder head symmetrically with respect to an axis are connected to receive pressurized oxidizer charge. At least two unvalved exhaust ports 33 having apertures 35 positioned in the cylinder wall symmetrically with respect to the axis are provided. The exhaust ports are exposed with the piston proximate bottom dead center and are operatively positioned with respect to the at least two valved inlet port orifices for forced gas exchange in the cylinder. At least one fuel injection device 100 introduces fuel symmetrically into the combustion chamber.
