BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body front structure, and more particularly to a vehicle body front structure having an engine control computer.

[0002]

2. Description of the Related Art Conventionally, in an automobile having an engine control computer, an engine control computer is arranged around a cockpit in a vehicle compartment in order to avoid damage caused by water and heat.

As shown in Japanese Utility Model Application Laid-Open No. 64-58375, a cowl extending in the vehicle width direction is provided at the front side of the windshield glass of the vehicle body, the upper end opening of which is covered with a cowl louver. A dash panel that separates the vehicle compartment from the engine compartment is provided at the bottom of the car.

[0004]

However, in the vehicle body front structure of this automobile, as shown in FIG. 4, the engine control computer 72 disposed in the vicinity of the cockpit of the vehicle interior 70 and the engine control computer 74 are disposed. The installed engine 76 is connected by a cord 80 penetrating the dash panel 78.

Therefore, the cord 80 between the engine control computer 72 and the engine 76 becomes long, and in the assembly process, after the engine 76 is mounted on the vehicle body, it is necessary to penetrate the dash panel 78 with the cord 80. The work for attaching the cord 80 is extremely difficult because there is no work space. Also,
It is possible to divide the cord and connect the cord on the engine side to the cord on the computer side for engine control in the engine room.In this case, it is necessary to provide a connector at the joint of the cord. The reliability of the part is reduced and the cost is increased.

In consideration of the above facts, the present invention makes it possible to shorten the cord length between the engine control computer and the engine and to improve the assembling workability of the engine control computer. Aim to get.

[0007]

According to a first aspect of the present invention, there is provided a box front portion of the cowl louver, and an engine control computer is housed in the box portion. .

According to a second aspect of the present invention, there is provided a vehicle body front structure according to the first aspect of the present invention, wherein the box portion is an air intake port provided in a cowl. It is characterized by being placed right above.

[0009]

According to the vehicle body front structure of the present invention as set forth in claim 1, since the engine control computer is housed in the box portion on the lower surface of the cowl louver, the engine control computer is arranged around the cockpit in the vehicle compartment. Compared with the conventional structure, the code length between the engine control computer and the engine can be shortened. Also, since the cord connecting the engine control computer and the engine does not penetrate the dash panel, the code for connecting the engine control computer and the engine penetrates the dash panel compared to the conventional structure in which the engine control computer is installed. Workability can be improved.

Further, in the vehicle body front structure of the present invention as set forth in claim 2, since the box portion accommodating the engine control computer is arranged directly above the air intake port provided in the cowl, The water that travels on the lower surface of the cowl louver is blocked by the side wall of the box and does not reach the air intake port provided on the cowl. Therefore, it is possible to prevent the water transmitted on the lower surface of the cowl louver from entering the air suction port.
