METHOD OF COLD START-UP AND WARM-UP OF PISTON INTERNAL COMBUSTION ENGINE AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC F02N99/00 

FIELD: engines and pumps.

SUBSTANCE: method involves hydrogen obtaining in electrolysis unit aboard the transport vehicle and the system that supplies hydrogen to the engine. At that, hydrogen is supplied in the required amount and as per the specified algorithm, depending on the cooling liquid temperature. Cold start-up and warm-up system includes electrolysis unit, pipelines, sensors, electric valves and control unit. Hydrogen and oxygen is obtained separately in the electrolysis unit. Hydrogen is supplied through receiver, electric valve and jet nozzle to ICE inlet pipeline. Oxygen is removed to the atmosphere. Supply of gaseous hydrogen to ICE inlet pipe at cold start-up and warm-up of the engine contributes to stable combustion of fuel-air mixture with higher degree of completeness at low concentration of toxic substances in waste gases.

EFFECT: reducing toxicity level of waste gases at cold start-up and warm-up of internal combustion engine with electronic control system and catalytic neutraliser.
