AIR-COOKED MOTOR lviilos Klavik, Prague-Smichov, Czechoslovakia Application September 1, 1939, Serial No. 293,137
In Czechoslovakia August 2, 1938 2 Claims.
This invention relates to an arrangement of the container which houses air-cooled motors, particularly in streamlined vehicles with motors at the rear.
Air-cooled motors of streamlined automobiles with motors at the rear are usually equipped with one or more blowers. The latter aspirate the air entering the container surrounding the motor and force it into the mantle surrounding the cylinders and the cylinder head. In order to prevent the heated air from mixing with the aspirated fresh cooling air, a casing of sheet metal or the like is arranged around the motor, which permits an escape of the heated air outwardly only through the louvres in the motor cover. This known arrangement has the great disadvantage that the motor housed in the sheet metal box is not at all accessible. v
This disadvantage is obviated according to the invention comprising the arrangement described hereinafter.
The motor container is divided into two parts by a horizontal or substantially horizontal wall in such a manner that the motor with its crank case, which in fact does not carry either inwardly or outwardly any components whatsoever necessitating access, projects into the lower part of the container into which the fresh air is supplied and whence it passes to the blowers, unless the latter are also accommodated in this lower part of the container. In the upper, perfectly accessible part of the motor container the cylinders and heads enclosed by a mantle are then mounted, as well as all parts of the motor which necessitate access.
A constructional example of the invention is shown diagrammatically in the accompanying drawing.
The rear part I of the body of the automobile is provided with a cover I hinged at 8 and the motor 2 is arranged in such a manner that through the wall 3 extending substantially horizontally and dividing the compartment into two parts, only the crank casing of the motor passes downwardly, whereas the cylinders with the heads and components necessitating good accessibility are situated above the said wall. It is advantageous also to accommodate the blower 4 in the, lower part of the compartment. The wall 3 can be bent upwardlyin the direction of the fresh air supply in the form of the part 5 and downwardly at the opposite end in the form of the part6, in order to ensure suitable access for the connecting of the crank handle to the motor shaft. The outlet of the blower 4 is connected with the upper part of the compartment by an aperture It in the wall 3.
If, due to constructional conditions and the construction of the motor, the arrangement of any part requiring inspection on the crank casing cannot be obviated, an opening adapted to be closed by a cover may be provided in the horizontal wall 3 for aWing suitable access to such parts.
I claim: 4
1. In an automobile, the combination of a body having a rear compartment with a hinged cover,
a transverse horizontal wall dividing the compartment into an upper and lower section, an engine in the compartment comprising cylinders in the upper section and a crank case in the lower section, a fresh air duct in front of said rear compartment and communicating with the lower section only, a blower in said lower section and hav ing its inlet connected with the latter and its outlet with the upper section, whereby the cylinders are on all sides surrounded by air flowing in the same direction,
2. In an automobile, the combination of a body having a rear compartment with a hinged cover, a transverse horinzontal wall dividing the compartment into an upper and lower section, an engine in the compartment comprising cylinders in the upper section and a crank case in the lower section, a fresh air duct in front of said rear compartment and communicating with the lower section, an upwardly extending wall of said fresh air duct forming a continuation of and being integral with said horizontal wall and being adapted to form a forward closure wall for said upper section, a blower positioned in said lower'section for delivering. the fresh air from said duct into said upper section to cool the engine cylinders in the same, the lower section being closed by a downwardly extending rear wall which forms a continuation of and is integral with said horizontal wall.
