Abstract
An internal combustion engine is provided with a separately formed intake passage for each cylinder. Each intake passage is provided with a fuel injection valve. The fuel injection valve is controlled to inject fuel in the latter half of the intake stroke of the corresponding cylinder. The amount of fuel injected from the fuel injection valve is increased upon acceleration of the engine by an amount which is separately determined for each cylinder and is generally reduced in the order of the firing order.
