Abstract: An intake system of an engine includes an engine and an intake manifold. The intake manifold defines individual intake air passageways each connecting one of cylinders to a volume chamber. Each of the individual intake passageways includes a first route and a second route. The first route has a natural frequency, of an air column, synchronized with a first revolution higher than an engine revolution for maximum torque such that a dynamic supercharging effect is obtained at the first revolution. The second route has a natural frequency, of an air column, synchronized with a second revolution higher than the engine revolution for maximum torque such that a dynamic supercharging effect is obtained at the second revolution. The second revolution differs from the first revolution. A difference between the first and second revolutions is set lower than or equal to 15% of a maximum engine revolution.

Abstract: An intake device of an engine comprises an intake manifold of a four-cylinder inline engine and a water-cooling type of intercooler. The intake manifold includes a downstream branch pipe portion connecting to cylinders, a chamber portion connecting to the downstream branch pipe portion, and an upstream intake pipe portion connecting to the chamber portion. A rectangular opening portion having a vertically-long shape is formed at the upstream intake pipe portion. The intercooler includes an intercooler body portion having a pair of faces which has the widest face-area and faces to each other in an engine width direction. The intercooler body portion is installed in the chamber portion, by being inserted through the rectangular opening portion, so as to divide an inside of the chamber portion into two parts in the engine width direction thereby.
