Abstract
In the air intake system of an engine which introduces air passed through a cleaner case having filter element therein into a throttle box through a throttle, and distributes the air from the throttle box to each cylinder of the engine by an intake manifold, the throttle is provided in the throttle box such that a center axis of the throttle is provided substantially horizontally and in a center in the vertical direction between the ends on the upstream side of the intake pipes. The intake pipes are provided on both sides of the throttle box and the throttle is connected to the throttle box such that a center axis of the throttle is arranged substantially horizontal and, simultaneously, an intake route for linking the throttle (including the main port) to the filter element is substantially arranged linearly on the center axis of the throttle. Also, the inside of the cleaner case is in the form of a hollow and is divided by a partition into the air cleaner case and a blowby room. The throttle box and the intake manifold are separately formed in advance and then are monolithically connected to each other.
