給式多気筒内燃機関。 At least one cylinder out of multiple cylinders sharing a common crankshaft is used as a supercharging cylinder for other combustion cylinders, and air taken into the supercharging cylinder via an intake passage with a check valve is transferred to the other combustion cylinders. In a multi-cylinder internal combustion engine configured to supply air to each of the combustion cylinders via a supercharging passage, a long low-speed atmospheric air intake is provided at the inlet end of the intake passage to the supercharging cylinder. The inlet pipe is connected to a short atmospheric air intake pipe for high speed use, and the connection portions of both atmospheric air intake pipes to the intake passage are provided with springs that keep the atmospheric air intake pipe for high speed use closed at all times. A pressure-operated intake switching valve is provided that opens the high-speed atmospheric air intake pipe when a pressure equal to or higher than atmospheric pressure acts on the pressure chamber, and the pressure chamber in the intake switching valve is connected to the supercharging cylinder. A check valve is connected to the supercharging passage from the combustion cylinder to the combustion cylinder via a pressure transmission passage, and in the pressure transmission passage there is a check valve that opens only in the direction of the pressure chamber, and a control valve that opens when the engine is in a high rotation range. A supercharged multi-cylinder internal combustion engine characterized by the following:
