Abstract: There are provided an engine disposed between right and left front side frames provided in an engine room, a radiator disposed obliquely such that its upper end is located forward in a disposition space in front of the engine, an air cleaner disposed above the radiator, and an electronic control device disposed in a space above the radiator and below the air cleaner. Accordingly, there can be provided a disposition structure of engine functional components for a vehicle which can properly dispose the electronic control device with respective to the radiator and air cleaner, preventing the temperature of the electronic control device from increasing.

Abstract: There are provided an engine disposed between right and left front side flames provided in an engine room, a radiator disposed obliquely such that its upper end is located forward in a disposition space in front of the engine, an air cleaner disposed above the radiator, and an electronic control device disposed in a space above the radiator and below the air cleaner. Accordingly, there can be provided a disposition structure of engine functional components for a vehicle which can properly dispose the electronic control device with respective to the radiator and air cleaner, preventing the temperature of the electronic control device from increasing.

Abstract: An intake system includes an air inlet passage for introducing air into an air cleaner. The air inlet passage is formed by an outside passage, formed with an inlet opening at an upper portion thereof and extending downward from the inlet opening, an inside passage, extending upward to the air cleaner, and a generally U-shaped intermediate passage, extending between the outside and inside passages so as to form a space therebetween. A liquid container is formed integrally with a stationary resonator disposed close to the space. The resonator is connected, by a connecting passage, with the air inlet passage at the generally U-shaped intermediate passage.

Abstract: A secondary air supply system for an internal combustion engine having a supercharger comprises a secondary air supply valve operable in response to the pulsating flow of exhaust gases emitted from at least one of engine cylinders. The remaining engine cylinders are communicated to an exhaust gas purifying device through a supercharger so that the exhaust gases emitted therefrom can drive a turbine of the supercharger. The exhaust gases emitted from such at least one of the engine cylinders are directly supplied to the exhaust gas purifying device in admixture with a secondary air supplied by the valve to facilitate an effective and efficient purification of the exhaust gases as a whole.
