an engine timing device configured to time gas flow in the internal combustion engine so that the piston has a longer effective expansion stroke movement than effective compression stroke movement during a functioning thermodynamic cycle of the piston, the engine timing device further configured to time gas flow in the internal combustion engine so that the piston has a power producing force from gas pressure acting on the piston and with the piston during movement of the piston;
wherein the power producing force is from expanding or contracting of gases in the internal combustion engine;
wherein the power producing force is not the force of expanding combustion gases, the power producing force is not the force from directing gas flow inertia, the power producing force is not the rebound force from expanding gases that were previously compressed mechanically by the internal combustion engine, and the power producing force is not the rebound force from compressing gases that were previously expanded mechanically by the internal combustion engine, and
wherein the power producing force occurs during a steady-state functioning thermodynamic cycle of the piston;

during the first stroke of the cycle, and after the piston has traveled about halfway toward the BDC position, exhaust gases begin to blow out of the cylinder;
during the first stroke of the cycle, as the piston is traveling towards the BDC position, cylinder pressure drops and the exhaust gases cease blowing out of the cylinder;
during the first stroke of the cycle, while the piston is traveling towards the BDC position, a greater amount of surface area of the cylinder is being exposed to hot gases in the cylinder and heat from the hot gases in the cylinder is being transferred to the surface area of the cylinder that is cooler than the hot gases;
during the first stroke of the cycle, while the piston is traveling toward the BDC position, gases in the cylinder cool and contract and decrease the gas pressure in the cylinder, thus causing intake flow into the cylinder;
during the cycle, when the piston reaches the BDC position, the piston reverses and starts to move toward the TDC position during a second stroke of the cycle;
during the second stroke of the cycle, when the piston is traveling toward the TDC position, the piston is decreasing the volume in the cylinder while intake gases are still capable of flowing into the cylinder from intake flow caused by cooling and contracting gases in the cylinder;
during the second stroke of the cycle, and after the piston has traveled about halfway toward the TDC position, intake flow into the cylinder ceases when a compression stroke displacement of the piston begins; and
during the second stroke of the cycle, when returning to TDC position in the cylinder, the piston finishes compressing gases in the cylinder.
