に流すのが最良である。The horizontal engine (4) and radiator (5) are installed with the hood tilted forward and lowered to reduce air pressure resistance to the vehicle body. The radiator (5) and intercooler (6) should be placed together in front of the cooling equipment.Reducing the internal shape will reduce the resistance caused by the cooling air flow, but it will also reduce the resistance caused by cooling air flow under the worst conditions and the heat generated by installing a turbo. Action is required. The air inflow plate (2) for cooling reinforcement is attached to the bonnet, bumper, or other single unit.
It is preferable to sense the temperature in the engine room using a sensor or thermostat, and open and close it using a motor. Air inflow plate (
For 2), it is best to raise the rear end higher than the front end when opening, and let the incoming cooling air flow smoothly under the bonnet while generating reverse lift.

You can also move it with The perspective view of FIG. 7 shows a method of increasing wind pressure to open the air outflow plate (3). Air outflow plate (3
) is extended forward from the leading edge of the arm (11), and a reverse lift plate (12) having an inverted airfoil cross section is attached to the tip of the arm (11). The opening force of the air outlet plate (3) due to the incoming airflow from the air inlet plate (2) is quite strong because the plate (12) is far from the axis. Resist the closing force,
Opens with wind power. □In order to smoothly open and close the shaft-mounted air outflow plate (3) using only wind power, airflow along both sides is used, but the leading edge force 1 generates reverse lift on both sides of about 1/3 of the total length. If you pivot at the center of the pivot point, the area behind the pivot point will be twice that of the front, allowing you to maintain an open angle in the wind direction. The trailing edge receives external airflow over the bonnet, but basically
The mounting angle of the air flow passage around the pivoting portion of the air outflow plate (3) determines the direction of the air flow, and the air outflow plate (3) opens generally along the internal flow.

ボによる発熱への対処が新しい課題となった。Heat dissipation onto the bonnet is more effective than the engine compartment, which utilizes the natural rise of hot air.It was common in older cars a long time ago, but it is now completely obsolete due to poor design and poor sound insulation from the engine. There is. However, dealing with the heat generated by the turbo has now become a new issue.

り、防音効果もある。The air inflow plate (2) whose upper end is open to the rear allows the air flow to reach the back side of the bonnet. Hot air enters the bonnet back air inlet (8) through the hot air outlet (7), which is a part of the air flow path (1) provided between the outer panel of the bonnet and the aggregate, and flows into the air outlet plate (3). Flowing but hot air exhaust path (7)
The air is crimped at the hot air outlet (9), which is a thin gap opened at the bottom, and the air flow is high in flow velocity and low in pressure based on the principle of Ventu IJ-'I. The hot air in the engine room is removed from the hood back air inlet (8) of the hot air exhaust path (7).
The hot air is drawn in from both the hot air outlet (9) and the air outlet plate (
3). The sound insulation material stretched on the back side of the bonnet, including the top surface of the hot air intake port (9) that narrows the hot air using the principle of misting, and the sound insulation material stretched on the lower side of the hot air exhaust path (7) narrow the hot air. Sound waves that travel straight from the engine and are reflected, leaking to the suction port (9)', etc., are absorbed, making it almost soundproof. If outside air is introduced by providing an air intake α1 in front of the hot air exhaust path (4) or on the bonnet in addition to the air in the engine room through the hood back air inlet (8), the amount of air flowing through the hot air exhaust path (7) can be increased. increases, and the hot air outlet (
9) The suction efficiency is improved. The air intake (t) is a cover that beautifully finishes the top surface, and also has a soundproofing effect.

前縁に接し、開いた状態を自重で安定させている。FIG. 5 is a perspective view of an embodiment in which the present invention is applied to reduce air resistance in a headlamp and its vicinity. In this embodiment, the rear edge of the air inlet plate (2) when closed is in contact with the front edge of the air outlet plate (3), and the open state is stabilized by its own weight.
前照燈の上部をカバーする空気流入板（２）は、不使用
時の前照燈の上部を覆い、空気抵抗を減少させている。An air inflow plate (2) covering the upper part of the headlight covers the upper part of the headlight when not in use, reducing air resistance.

上下の差によ如逆揚力を発生させる事ができる。The air inflow plate (2) is pivoted at both ends of the trailing edge to minimize increase in air resistance and deterioration of style even when opened when the headlights are in use. The more rearward the pivoting part of the air inflow plate (2) is, the lower the front edge can be than the rear edge when opened. The position of the air inflow plate (2) is a part where 1% force and air resistance occur because air cannot pass through the underside of the current car. In FIG. 6, even when opened, the leading edge of the air inflow plate (2) is lower than the trailing edge, and although the cross section is airfoil-shaped, little lift is generated. In addition, the overall airflow after passing through the air outflow plate (3), even when the air inflow plate (2) is open, has a faster flow rate and lower pressure on the lower side than the upper side, so the air pressure will rise and fall. A reverse lift force can be generated by the difference between the two.

The trailing edge opens using wind pressure without the need for a motor. When the air inflow plate (2) is opened, the direction of the airflow changes and the angle of the air outflow plate (3) changes, but the position of each shaft attachment part should be adjusted to minimize this change. The size of the opening can be controlled. Alternatively, the rear edge of the air inlet plate (2) may not be brought into contact with the front edge of the air outlet plate (3), and the closed state of the air outlet plate (3) may be maintained using another method. In order to ensure the same reverse lift force when the headlights are in use, and to further strengthen the reverse lift force when they are not in use, the air outflow plate (3) may also be moved by a motor to hold the rear end high.

There are various mounting positions and methods for installing the air inlet plate (2), such as in front of the headlight or radiator, but the force of the air flow acting on the air outlet plate (3) is always transferred to the air inlet plate (2).
2) changes depending on whether it is opened or closed.

良くするには、ポンネ・ソトヘの取付がペターである。If the rear edge of the air inflow plate (2) touches the front edge of the air outflow plate (3), it is appropriate that both of them be pivoted to the bonnet, and their lower sides should be connected to the air flow passage (1). ). When the air inlet plate (2) and the air outlet plate (3) are separated, they can be attached to the bonnet, the vehicle body, a bumper, or the like. In order to enlarge the opening of the engine room and improve maintainability, it is necessary to install Ponne Sotohe.

抗は少ない。In order to improve aerodynamic characteristics by integrating internal and external airflow, and to improve space efficiency within the engine room, it is necessary to treat the central area where the engine and radiator are located, and the areas on both sides where the headlights are installed, separately. It is also easier to drive if both sides of the front end of the bonnet can be visually checked from the driver's seat, and it is better for the hood to be flat and have folds in the panels in terms of visible external shape, but the front of the vehicle body is The rounder it is, the less resistance it will have.
