Disclosed is a low-fuel consumption and low-pollution combustion system for supplying a vehicle engine with a mixture of fuel and oxygen. The low-fuel consumption and low-pollution combustion system supplies the vehicle engine with the mixture of fuel and oxygen, in which oxygen contained in air is separated from nitrogen through a PSA (pressure swing adsorption) scheme so that oxygen having purity above 95% is obtained and a mixture of fuel and oxygen is fed into a combustion chamber of the vehicle engine and burned in the combustion chamber of the vehicle engine, thereby obtaining a desired engine output with low-fuel consumption, and in which nitrogen (N ) is previously removed so that an amount of nitride oxide (Nox) can be minimized during the combustion procedure and CO and toxic gas derived from incomplete combustion can be minimized by achieving complete combustion. The low-fuel consumption and low-pollution combustion system obtains 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 includes an oxygen separator 11 for separating oxygen contained in air from nitrogen by introducing external air into adsorption towers 17a and 17b 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; 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.
