An internal ballistic engine for providing high thermal efficiency comprising a housing, a powering chamber, a ballistic piston, not directly engaged with the output shaft in the state of motion of the piston, primarily depending on its mass moment of inertia and the internal forces provided by the powering chamber, this piston is disposed in, and movable in the powering chamber, for accumulating a substantial portion of the internal energy in the powering chamber as kinetic energy in conjunction with its mass moment of inertia, such transfer of energy causing the temperature and pressure in the powering chamber to be drastically reduced, therefore lowering the rate of loss of heat to the walls; a second chamber, in tandem with the powering chamber, so that the second chamber is being compressed as the powering chamber is being expanded, whereby the kinetic energy accumulated on the ballistic piston is being converted into potential energy temporarily stored in the second chamber; means of interaction between the second chamber and the output shaft whereby rotational driving energy is being transferred to the output shaft. Holding and release means are provided for controlling the compression ratio as a result of the motion of the ballistic piston inside the powering chamber, in terms of the amount of fuel flowing into the engine for further optimum of the thermal efficiency of the engine.
