Abstract: A method and device to optimize the cumulative beneficial effect of harvesting available forms of lost energy, including energy that is lost while a vehicle is in motion (e.g., kinetic energy and energy contained in electromagnetic radiation. The cumulative energy that is recovered is converted to electrical energy which powers the on-board electrolyzer to produce more hydrogen and oxygen while the system is in operation and stationary. Stationary, passive forms of energy (e.g., solar, wind, hydro, etc.) will also be available to power the electrolyzer. The system also contemplates using passive forms of energy to power a non-mobile system which incorporates an internal or external combustion engine in place of a fuel cell. An oxygen injection control device is employed to control the supply of oxygen to the combustion engine.

Abstract: When knocking occurs, a control apparatus for an internal combustion engine increases the rotational speed of a pump to increase the flow rate of a coolant supplied to an area near a combustion chamber wall surface, and controls an actual mechanical compression ratio to a low mechanical compression ratio lower than a mechanical compression ratio set based on the load of the engine. Thus, the pressure of end gas is decreased, and occurrence of knocking is suppressed. Then, the actual mechanical compression ratio is returned to the mechanical compression ratio at a time point at which the temperature of the combustion chamber wall surface has been sufficiently decreased due to the increase in the rotational speed. Thus, occurrence of knocking is suppressed while avoiding the situation where the actual mechanical compression ratio continues to be controlled to the low mechanical compression ratio that is lower than the mechanical compression ratio.
