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

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a track-type engine having symmetrical inclined cylinders, and more particularly, to a track-type engine having symmetrical inclined cylinders capable of minimizing the number of components and volume, To a track-type engine.

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- (Patent Application No. 2004-000372 filed on January 19, 2004), two rollers roll on the raceway surface of the cam, and the ball portion of one ball rod is wound on the track of the hump track portion A cam-type engine that slides in a groove is disclosed in Korean Patent Application No. 2004-0003763 (filed on January 19, 2004). The main roller rolls on the raceway of the cam, the auxiliary roller rolls on the raceway groove of the hump track portion, And the auxiliary roller are filed by the present applicant in Korean Patent Application No. 2004-0003764 (filed on January 19, 2004), which is installed on the same axis line.

In each cylinder of the track-type engine having such a cam-type engine and a hump-symmetrical inclined cylinder, ignition means having an intake and exhaust means having an intake and exhaust valves and an ignition plug are provided, and in the case of a diesel engine, An exhaust means and a fuel injection means are provided, and the intake and exhaust means is 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 cylinder, which are provided together with the separate cam mechanism, a separate cam for operating the valve in synchronization with the rotation of the cam and hump track portion There is a problem that the structure is complicated due to the mechanism, the number of components is increased, the volume is increased, the manufacturing cost is increased, and the operation reliability is low due to the failure of the component.

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

However, a separate intake passage and an exhaust passage are formed on the outer peripheral surface of the piston 300, It goes without saying that a cycle engine may be applied.

One end of the connecting rod 310 is provided with a piston head 301 connected by a piston pin 330. The piston head 301 is connected to the ceiling of the combustion chamber C of the cylinder head assembly 400 So as to reciprocate close to the ignition plug 420 to be installed.
