Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement of a cooling system for a transverse engine in which the center of the crankshaft extends in the width direction of the vehicle body.

(Prior Art) Conventionally, in the case of a horizontally mounted engine, an exhaust manifold is provided at the front end of the engine in the width direction, and a radiator equipped with a cooling fan is provided in front of the transmission to prevent interference with the manifold. There is.

In addition, in the case of a car equipped with an air conditioner, the air conditioning condenser is arranged next to the radiator, and generally a radiator grille for taking in air from the vehicle is provided in front of the radiator and condenser. (Refer to Publication No. 135315).

Furthermore, in the case of engines equipped with a carburetor, when the outside temperature is low, hot air around the exhaust manifold is guided into the combustion chamber via the carburetor to improve fuel atomization and vaporization.The hot air supply passage is connected to the air cleaner intake duct. known to connect.

(Problems to be Solved by the Invention) By the way, in the case of a car that is not equipped with an air conditioner, an air conditioning condenser is not provided, and a space (dead space) is formed behind one side of the radiator grill.

Therefore, when driving in the snow in winter, snow passes through the gap in the radiator grille and enters the engine compartment, and the snow that enters the engine compartment adheres to the exhaust manifold, and the steam generated by the heat of the exhaust manifold flows through the hot air supply passage. There was a problem in that the fuel entered the intake passage through the engine, causing deterioration of combustion and causing a decrease in engine speed while driving.

(Means for Solving the Problems) In order to solve the above problems, the present invention has been developed to provide a wind guide system in front of the exhaust manifold in the engine room behind the radiator grille to guide the running air from the radiator grille downward into the engine body. A plate member is provided, and the plate member is composed of a stay member and a plate member whose respective upper parts are attached to the radiator shroud panel of the vehicle body with their respective upper parts spaced apart from each other in the front and back, and both lower ends of the stay member and the plate member are joined to form a rear part. It is bent downward.

(Function) According to the present invention having the above configuration, even if snow passes through the gap between the radiator grilles when a vehicle without an air conditioner is installed in a snowy winter, the snow is guided downward to the engine by the wind guiding plate member. , snow adhesion to the exhaust manifold is prevented. Therefore, no steam is generated in the exhaust manifold section, and no steam enters the intake duct of the air cleaner from the hot air supply passage. Therefore, deterioration of combustion due to steam entering the intake passage can be prevented, so that the engine speed does not decrease while the vehicle is running.

(Example) Next, an example of the present invention will be described with reference to FIGS. 1 to 3.

A horizontal engine 1 shown in FIG. 1 is installed in an engine room 3 of a vehicle body 2, and a crankshaft center (not shown) extends in the width direction of the vehicle body 2.

A radiator grille 4 installed in the front of the engine room 3 extends in the vehicle width direction and includes an outside air inlet 4a.

A radiator 5 is mounted offset to one side of a radiator shroud panel 2a of the vehicle body 2 located behind the radiator grille 4.

As shown in FIG. 2, the radiator 5 has bracket members 8 and 9 attached to its upper and lower parts via rubber members 6 and 7, and a fan cowling 10 and an electric fan 11 are provided at the rear thereof.

Since the vehicle is not equipped with an air conditioner, no air conditioning condenser is provided on the other side of the radiator shroud panel 2a, and a dead space exists.

Exhaust manifold 1 is installed at the rear of the dead space.
The exhaust manifold 12 is provided with a hot air supply passage 14 that guides hot air around the manifold 12 to the intake passage through the intake duct 13a of the air cleaner 13.

Intake duct 13 of the hot air supply passage 14
An on-off valve (not shown) is generally provided at the connection part a, and the on-off control of the valve is opened, for example, when the intake temperature is low or when the load is low.

As shown in FIGS. 2 and 3, an air guide plate member 15 is provided in the dead space, that is, on the other side of the radiator shroud panel 2a, facing the radiator grille 4. As shown in FIGS.

The plate member 15 has a stay member 1 whose upper portion is fixed to the front surface of the radiator shroud panel 2a.
5a, and a plate member 15b that is provided opposite to the stay member 15a and whose upper portion is fixed to the rear surface of the radiator shroud panel 2a.

The stay member 15a and the plate member 15b are joined at both lower ends and bent rearward.

The stay member 15a is entirely bent rearward, and is formed so that its width becomes wider as it goes downward.

The plate member 15b is entirely bent forward, and its lower portion is overlapped with the stay member 15a.

In addition, the stay member 15a and the plate member 1
The upper part of 5a is attached using the bolt hole for attaching an air conditioning condenser.

(Effects of the invention) As described above, according to the invention, snow that has passed through the gap in the radiator grill does not adhere to the exhaust manifold, thereby preventing deterioration of combustion caused by steam entering the intake passage. First, it is possible to prevent the engine speed from decreasing during driving.

In addition, since the wind guiding plate member is configured to reinforce the plate member with the stay member, the rigidity of the wind guiding plate member itself is improved, which is extremely advantageous against collisions with traveling wind.
