ジン。A large number of cylinders in an engine equipped with a supercharger are grouped into multiple cylinder groups whose intake valve opening timings do not substantially overlap, and a common intake pipe is provided for the cylinders in each group, and these common pipes are connected to each other. In addition to providing an on-off valve that communicates with, shuts off, or disconnects the common air intake pipes, an intake supply pipe that communicates with each intake common pipe on the downstream side and joins each other on the upstream side is provided, and by closing the on-off valve, the relatively low temperature of the engine is provided. In the configuration in which the confluence point is set so that an inertial supercharging effect occurs in a set rotation speed range, the on-off valve is opened only when the engine is at low rotation speed and under low load, and is closed under other engine operating conditions. A multi-cylinder engine with a supercharger characterized by being configured as follows.
