This patent describes improvement in a cyclic char burning power reactor comprising: at least one combined means for compressing and expanding gases, each the combined means comprising; an internal combustion engine mechanism comprising a variable volume chamber for compressing and expanding gases, and drive means for driving the internal combustion engine mechanism and for varying the volume of the chamber through repeated cycles, each cycle comprising a compression time interval followed by an expansion time interval. The improvement comprises dividing the peripheral dimension of the primary reaction chamber into a separate inlet portion, a separate outlet portion, and a separate sealed portion; and adding to each the primary reaction chamber: a reactant gas manifold comprising an inlet and an outlet, the outlet connecting to reactant gas inlet ports into the primary reaction chamber, a producer gas reservoir comprising an inlet, the inlet connecting to producer gas outlet ports out of the primary reaction chamber, wherein all of the reactant gas inlet ports and also all of the outlet ports are smaller in at least one area cross section dimension than the char fuel particles being refueled into the primary reaction chamber; a reactant fixed open gas flow connection from the variable volume chamber of the internal combustion engine mechanism to the inlet of the reactant gas manifold.
