。 In a four-cylinder engine in which a throttle valve 3 is disposed at a gathering part 2 of a branch pipe 1 and one electromagnetic fuel injection valve 4 is disposed upstream of the throttle valve 3, the branch pipe 1 is connected to the intake order. The branch pipes 1-1 and 1-2 are divided into a first branch pipe 1-1 and a second branch pipe 1-2 that distribute and supply air to two cylinders 5 that are not adjacent to each other. A throttle valve 3 is arranged in each of the collecting parts 2-1 and 2-2 of the first branch pipe 1.
-1 and the collecting part 2-2 of the second branch pipe 1-2 are opened to face the fuel nozzle of the electromagnetic fuel injection valve 4, and the fuel of the electromagnetic fuel injection valve 4 is opened. A fuel injection four-cylinder engine characterized in that the time interval between injections is twice the time interval between ignitions, and the amount of fuel equivalent to two cylinders is injected during one fuel injection.
