A system includes an electrolysis unit capable of producing hydrogen and oxygen gases and interoperably connected to a diesel engine. The amount of amount of hydrogen and oxygen gases produced by the electrolysis unit is proportionally correlated to the stroke type and stroke displacement of the diesel engine. The system also includes a power supply system that is interoperably connected to the electrolysis unit. The power supplied by the power supply system is proportional to an amount of hydrogen and oxygen to be supplied to the diesel engine. The system also includes a safety mechanism interoperably connected to the power supply system so as to terminate power to the electrolysis unit in response to cessation of operation of the diesel engine.
