An internal combustion engine having a plurality of cylinders which is divided into a first cylinder group and a second cylinder group. The engine comprises first and second air control means for controlling an amount of intake air fed into the first and second cylinder groups, respectively, and first and second fuel supply means for supplying the first and second cylinder groups with fuel. The second air control means allows inflow of air into the second cylinder group when the level of the load of the engine is lower than a predetermined level. The second fuel supply means supplies an amount of fuel in accordance with the amount of intake air passing through a second intake passage of the second cylinder group when the level of the load of the engine is higher than the predetermined level, and stops the fuel supplying operation when the level of the load of the engine is lower than the predetermined level. The engine further comprises an actuating means for increasing an amount of intake air passing through the first air control means in accordance with an increase in the level of the load of the engine, and for increasing an amount of intake air passing through the second air control means in accordance with an increase in the level of the load of the engine when the level of the load of the engine exceeds the predetermined level. The increasing speed of the amount of intake air passing through the second air control means is controlled higher than the increasing speed of the amount of intake air passing through the first air control means.
