Abstract
The invention relates to an internal combustion engine which is designed mainly for solving the problems of large lateral stress to a cylinder wall when a piston moves up and down and low power of the existing internal combustion engine. The internal combustion engine comprises a lower box body, an upper box body, an air cylinder, a cylinder cover, a cam shaft, an air inlet cam, an air exhaust cam, an air inlet door, an air exhaust door, a fuel spray nozzle or a spark plug, a straight bar guiding sleeve, a piston, an output shaft, a straight-bar shaft, a straight bar, a central shaft, a connecting rod, an output shaft sprocket, a chain and a cam shaft sprocket, wherein a crank gear is connected with an output shaft gear, and the straight-bar shaft deviates from the center of the crank gear. The internal combustion engine has the advantages that when the piston moves up and down, the central shaft deviates from the center of the cylinder body, lateral stress is not generated to the cylinder wall, and the work efficiency is high.
Description
Technical field:
The present invention relates to a kind of internal-combustion engine.
Background technique:
The bent axle of existing internal-combustion engine is made up of output shaft, pitman shaft and crank, and output shaft-end wherein is contained in crank center, and the output shaft the other end is contained on the casing, and it is big when shortcoming is piston up-down casing wall to be produced lateral stress, and effect is low.
Summary of the invention:
When the technical problem to be solved in the present invention provides a kind of piston up-down casing wall is not produced lateral stress, internal-combustion engine that effect is high.
The objective of the invention is such.Same as the prior art is, it also comprises lower box, the lower box top is a upper box, and the upper box top is that cylinder body, cylinder body top are cylinder caps, and camshaft is arranged in the cylinder cap, intake cam and exhaust cam are arranged on the camshaft, there is intake valve the intake cam below, and there is exhaust valve the exhaust cam below, and (diesel engine has oil nozzle to also have oil nozzle or spark plug in the cylinder cap, petrol engine has spark plug), unlike the prior art be; Bent axle is made up of central shaft, straight-bar axle and crank gear, fixing straight-bar leading cover is arranged on the casing, piston is arranged in the cylinder body, fixing straight-bar is arranged on the piston, straight-bar is connected with the straight-bar axle, the straight-bar axle departs from the crank gear center, and crank gear and output shaft gear join, and there is central shaft at the crank gear center, connecting rod is housed on the central shaft, connecting rod links to each other with output shaft, and the output shaft sprocket wheel is arranged on the output shaft, is connected with camshaft sprocket on the camshaft by chain.
Advantage of the present invention is: during piston up-down, casing wall is not produced lateral stress, the effect height.
Description of drawings:
Fig. 1 is a cross-sectional view of the present invention.
Fig. 2 is a working procedure schematic representation of the present invention.
Embodiment:
With reference to Fig. 1.
It also comprises lower box 16, the lower box top is a upper box 10, the upper box top is a cylinder body 8, the cylinder body top is a cylinder cap 1, camshaft 2 is arranged in the cylinder cap, intake cam 6 and exhaust cam 7 are arranged on the camshaft, there is intake valve 3 the intake cam below, there is exhaust valve 4 the exhaust cam below, also has oil nozzle or spark plug 5 (diesel engine has oil nozzle, and petrol engine has spark plug) in the cylinder cap, bent axle is by central shaft 13, straight-bar axle 11 and crank gear 17 are formed, fixing straight-bar leading cover 22 is arranged on the casing, piston 9 is arranged in the cylinder body, fixing straight-bar 12 is arranged on the piston, straight-bar is connected with the straight-bar axle, and the straight-bar axle departs from the crank gear center.Crank gear and output shaft gear 14 join, and there is central shaft 13 at the crank gear center, and connecting rod 15 is housed on the central shaft, and connecting rod links to each other with output shaft 18, and output shaft sprocket wheel 19 is arranged on the output shaft, are connected with camshaft sprocket 20 on the camshaft by chain 21.
Working procedure: with reference to Fig. 2, Starter drives the output shaft rotation during work beginning, output shaft gear drives crank gear rotation (central shaft departs from the cylinder body center), the straight-bar axle drives straight-bar and makes descent of piston, output shaft sprocket wheel 19 links to each other with camshaft sprocket 20 by chain 21, driving camshaft makes intake valve open piston operation from top to bottom in cylinder, the certain degree of vacuum of instantaneous generation between piston head and the firing chamber, promptly produce certain suction, gas this moment (or inflammable gas) enters combustion chamber of air cylinder's (seeing Fig. 2 A) by intake valve: output shaft gear drives the crank gear rotation, central shaft departs from the cylinder body center, the straight-bar axle promotes straight-bar and makes piston stroking upward, advance, exhaust valve is in closed condition (seeing Fig. 2 B): pressurized gas oil nozzle oil spout at the end (or plug ignition) burning, gas expands and produces explosive force, promote descent of piston, central shaft departs from the cylinder body center, straight-bar promotes the straight-bar axle and exercises the rotation of crank gear rotation drive output shaft gear down, outputting power (seeing Fig. 2 C): outburst at the end, output shaft gear and crank gear rotation, central shaft departs from the cylinder body center moves upward piston, and exhaust valve is opened the air scavenge cylinder body in the cylinder body outer (seeing Fig. 2 D).
