Abstract

An engine room cooling system may include an encapsulation covering an intake manifold and an exhaust manifold of an engine of a vehicle, a main duct guiding traveling wind flowing into the vehicle to a side of the encapsulation, an encapsulation intake duct branched from the main duct and formed toward the intake manifold within the encapsulation, an encapsulation exhaust duct branched from the main duct and formed toward the exhaust manifold within the encapsulation, and an intake duct valve disposed adjacent to the encapsulation intake duct and controlling air flow from the main duct to the encapsulation intake duct or to the encapsulation exhaust duct.

First claim

What is claimed is:

1. An engine room cooling system comprising:
an encapsulation covering an intake manifold and an exhaust manifold of an engine of a vehicle;
a first main duct guiding traveling wind flowing into the vehicle to a side of the encapsulation;
an encapsulation intake duct branched from the first main duct and formed toward the intake manifold within the encapsulation;
an encapsulation exhaust duct branched from the first main duct and formed toward the exhaust manifold within the encapsulation; and
an intake duct valve disposed adjacent to the encapsulation intake duct and controlling air flow from the first main duct to the encapsulation intake duct or to the encapsulation exhaust duct.

2. The system of claim 1 , wherein the encapsulation intake duct is disposed further forward of the vehicle as compared to the encapsulation exhaust duct.

3. The system of claim 1 , wherein the engine is a single intake I type engine; and
the first main duct, the encapsulation intake duct and the encapsulation exhaust duct are formed to one side of the engine.

4. The system of claim 1 ,
wherein the engine is a single intake V type engine,
wherein the first main duct, the encapsulation intake duct and the encapsulation exhaust duct are formed to one side of the engine, and
wherein the system further comprises a second main duct and a second encapsulation exhaust duct which is branched from the first main duct and formed toward the exhaust manifold within the encapsulation at a side of the engine opposite to one side of the engine.

5. The system of claim 1 ,
wherein the engine is a dual intake V type engine, and
wherein the first main duct, the encapsulation intake duct and the encapsulation exhaust duct are formed as a pair and disposed to both sides of the engine.

6. The system of claim 1 , further comprising:
a coolant temperature sensor sensing coolant temperature within the engine and outputting a corresponding signal;
a temperature sensor sensing temperature within the encapsulation and outputting a corresponding signal;
a speed sensor sensing speed of the vehicle and outputting a corresponding signal; and
a control portion receiving operation state information of the vehicle including outputting signals of the coolant temperature sensor, the temperature sensor and the speed sensor, determining whether cooling of the exhaust manifold is required or not, and controlling operations of the intake duct valve for the traveling wind to flow toward the encapsulation exhaust duct when cooling of the exhaust manifold is required.

7. The system of claim 1 , wherein the encapsulation intake duct is connected with an air filter.
