Abstract
Abstract An engine compartment structure of a vehicle for introducing cool air into an air intake port without a baffle plate is provided. The structure is constructed such that an air intake port is located behind a first headlamp in the engine compartment, the opening of the air intake port is directed toward the front of the compartment, and the rotational direction of cooling fans for the radiator is determined such that the air discharged by the one or more radiator cooling fans is directed away from the location of the intake air port of the engine, and towards a side behind a second headlamp which is opposite to the first headlamp in the engine compartment.
