ANDREEV INTERNAL COMBUSTION ENGINE FEED SYSTEM Russian patent published in 2012 - IPC F02M25/25 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine feed system includes fuel feed device, fuel-air mixture preparation and supply device to engine combustion chambers, air filter, air treatment device that is made in the form of the main and additional water reservoirs, inlet and outlet connection pipes, water temperature control, water level maintaining device in reservoir and a water tank. System is equipped with water pump connected through the inlet to the tank, and through the outlet to additional reservoir, and air supply device through slots made in additional reservoir, which is made in the form of a flat ring with projection located at the outlet of inlet connection pipe above water surface. Water level maintaining device is made in the form of a hollow cylinder the carrying capacity of which is higher than that of water pump, located at the bottom of the main reservoir along its axis and connected through the inlet by means of a screw to additional reservoir. Water temperature control is made in the form of tubular spiral heater with outer diameter equal to inner diameter of additional reservoir, spiral pitch, which is equal to 1.2 of tube diameter, located in water near its surface and connected in parallel through adjustable throttle to liquid temperature control of the engine.

EFFECT: reduction of toxicity level of waste gases as to CO, CH, NOx and smoke content, and fuel flow.
