Claim:
A low-fuel consumption and low-pollution combustion system capable of obtaining a high engine output with low-fuel consumption by reducing toxic gas derived from incomplete combustion through feeding a mixture of oxygen and fuel into a vehicle engine 1 , the low-fuel consumption and low-pollution combustion system comprising: an oxygen separator 11 for separating oxygen contained in air from nitrogen by introducing external air into adsorption towers 17 a and 17 b with predetermined pressure while storing the oxygen separated from the nitrogen in an oxygen storage tank 20 and exhausting the nitrogen an exterior; an intake pipe 30 communicated with the engine 1 so as to feed the oxygen stored in the oxygen storage tank 20 into a combustion chamber 2 of the engine 1 ; a first pressure regulator 21 and a first oil/water separator 22 sequentially connected to a transport pipe 23 connecting the intake pipe 30 to the oxygen storage tank 20 , the first pressure regulator 21 transporting the oxygen stored in the oxygen storage tank 20 to the combustion chamber 2 of the engine 1 through the intake pipe 30 while regulating pressure of the oxygen, the first oil/water separator 22 separating water from the oxygen; an oxygen temperature control unit 40 connected to the intake pipe 30 so as to improve a combustion efficiency by maintaining the temperature of the oxygen fed into the engine 1 at a constant level regardless of external environment, wherein the oxygen temperature control unit 40 includes: a temperature rise manifold 41 provided at one side thereof with a pressure regulator 42 in order to receive a part of oxygen contained in the intake pipe 30 through the pressure regulator 42 and a lower portion of which is connected to an exhaust manifold 5 of the engine 1 so as to feed heated oxygen to the intake pipe 30 by heating the oxygen transferred thereto from the pressure regulator 42 , a control valve 44 for selectively opening/closing an inlet of the temperature rise manifold 41 and an internal passage of the intake pipe 30 , and a vacuum controller 43 installed at one side of the intake pipe 30 in order to operate the control valve 44 under a control of a temperature detector 45 which detects a temperature of the oxygen in the intake pipe 30 ; and a proportional oxygen sensor 32 checking a density of the oxygen passing through the intake pipe 30 and sending a signal thereof to an electronic control unit (ECU) 50 , wherein the ECU 50 controls the above individual elements based on information transmitted thereto from the proportional oxygen sensor 32 to feed the oxygen and fuel into the combustion chamber 2 of the engine 1 with an optimum mixture ratio.
