DESCRIPTION:
BRIEF SUMMARY
1. Technical Field
The present invention relates to a cylinder having a special cross-sectional configuration and a piston received therein, which are arranged so as to enhance the output of an internal combustion engine for activating an automobile or the like and to considerably increase the efficiency thereof. More particularly, the present invention pertains to a structure of a rotor composite engine which employs such cylinder and piston having special cross-sectional configurations, together with a rotor journal and a main journal.
2. Background Art
There have heretofore been various types of internal combustion engine for activating automobiles or the like, i.e., the reciprocating piston type, the rotor type, a combination of the piston type and the rotor type in which the former is dominant, and a combination of the rotor type and the piston type in which the former is dominant. These various types of engine are employed in accordance with uses or the kind of apparatus which make use of them. Therefore, it is impossible to expect a uniform engine structure. This is described, for example, in "Automobile Maintenance and Repair Techniques, Second-Class Gasoline-Fueled Automobiles" compiled and published by Federation of Japan Automobile Maintenance and Repair Promoting Associations, Corp.
Disclosure of Invention
Thus, the type of internal combustion engine depends on the use or the kind of applied apparatus, and it has not yet been answered to the question as to which engine type is appropriate for enhancing the engine output and amplifying the efficiency thereof.
In view of the above-described problems of the prior art, it is an object of the present invention to provide a structure of an engine which does not belong to either the conventinal rectilinear reciprocation piston type or the conventional rotor type but has a cylinder the cross-sectional configuration of which defines a predetermined curved surface and a piston having the same curved surface as that of the cylinder, thereby enabling the arcwise reciprocating motion of the piston to be readily converted into rotational motion. Further, the above-described cylinder and piston having special configurations are arranged to form a rotor composit engine which employs a rotor journal and a rotor gear, thereby efficiently converting the above-described arcwise reciprocating motion into rotational motion and thus enhancing the engine output and amplifying the efficiency thereof to solve the above-described problems.
The present invention provides a structure of an engine employing a cylinder the cross-sectional configuration of which defines a predetermined curved surface and a piston having the same curved surface as that of the cylinder. Since the piston performs arcwise reciprocating motion, rotational motion of a shaft can be readily obtained.
The above-described rotational motion of the shaft can be obtained at high efficiency by arranging the cylinder and piston having such special configurations in the form of a rotor composite engine which employs a rotor journal and rotor gear.
