An exhaust control method of combustion gas for a supercharged indirect injection engine and the engine thereby are provided to decrease fuel consumption, and to prevent pollutants such as hydrocarbon by evenly mixing air and fuel in a combustion chamber. An indirect injection engine includes a cylinder(10) having a combustion chamber(12), two intake units(14,16) having pipes(18,20) controlled by intake valves(22,24), fuel injection units(26,28) related to the intake units, and a combustion gas exhaust unit(30) having an exhaust valve(32). The indirect injection engine is controlled by supplying non-carbureted air through the intake unit and carbureted air through the other intake unit in finishing exhausting air and feeding carbureted air with two intake units. The intake valve and the exhaust valve are overlapped by using pressure of air with the intake unit having pressure to be more than gas pressure of the exhaust unit.
