Description

TRACK TYPE ENGINE WITH SYMMETRICALLY INCLINED AND VERTICAL CYLINDER < RTI ID = 0.0 >

The present invention relates to a track-type engine having symmetrical inclined and vertical cylinders, and more particularly, to a track-type engine having a symmetrical inclined shape capable of minimizing the number of components and volume, And a track-type engine having a vertical cylinder.

Generally, a gasoline engine and a diesel engine have a piston-crankshaft mechanism in which a piston and a crankshaft are connected to each other by a connecting rod so as to convert a linear motion of a reciprocating piston in a cylinder into a rotary motion.

In the case of a four-stroke engine, two reciprocating movements of the piston cause a single explosion while the crankshaft makes two rotations, performing a four-stroke cycle of suction, compression, expansion and exhaust.

In this reciprocating engine, since explosion is performed once during the reciprocating motion of the piston twice, there is a limit in obtaining a large output. In addition to the reaction force of the output torque, the inertial force of the connecting rod acts as a side pressure on the piston. Since friction and impact against the cylinder are large and constant force is applied to the connecting portion between the connecting rod and the piston and the crankshaft in different directions, a material having a high strength, rigidity and yield point is required and the production cost can not be lowered. And the crankshaft, there is a limit in reducing the size and weight of the engine.

In order to realize the miniaturization and weight reduction of the above-described reciprocating engine, Korean Patent Application No. 2004-0003761 filed by the present applicant (filed on January 19, 2004) discloses a hump-symmetric hammering device in which two rollers roll in a hump- Type engine having an inclined and vertical cylinder is disclosed in Korean Patent Application No. 2004-0003762 (filed on January 19, 2004), in which two rollers roll on the raceway surface of the cam and the ball portion of one ball- A cam-type engine that slides on the track groove of a track portion is disclosed in Korean Patent Application No. 2004-0003763 (filed on January 19, 2004). The main roller rolls on the raceway surface of the cam and the auxiliary roller rolls on the raceway groove of the hump track portion. The cam-type engine installed on the same axial line as the main roller and the auxiliary roller is filed by the present applicant as Korean Patent Application No. 2004-0003764 (filed on January 19, 2004).

In each cylinder of the track-type engine having such a cam-type engine and a hump-symmetrical inclined-type and vertical cylinder, ignition means having an intake and exhaust means having an intake and exhaust valves and an ignition plug are provided, The cylinder is provided with intake / exhaust means and fuel injection means, which are installed together with a separate cam mechanism so as to operate in synchronization with the rotation of the cam and the hump track portion.

However, in the valve system of the track-type engine having the conventional cam type engine and the hump symmetric inclined type and vertical type cylinders installed together with the separate cam mechanism in this way, in order to operate the valve in synchronization with the rotation of the cam and the hump track portion There is a problem that due to the separate cam mechanism, the structure is complicated, the number of components is increased, the volume is increased, manufacturing cost is increased, and operation reliability is low due to failure of parts.

Korean Patent No. 10-0616062 Korean Patent Application No. 2004-0003762 Korean Patent Application No. 2004-0003763 Korean Patent Application No. 2004-0003764
