The internal-combustion engine applies the force-assisting angle, which adds greatly the original power, and the acting path of the corresponding force is shortened; through estimation, the total reactive force is added, particularly the torsional moment is greatly increased, the power is added, and the oil-saving effect is obvious.
Description
Technical field the invention belongs to the power category technical field of internal combustion engines, specifically a kind of piston type cyclotomy internal-combustion engine.
Background technique is present, and in the existing internal-combustion piston engine technical field of China (mainly referring to vapour, diesel engine), the piston in the internal-combustion engine directly links to each other with crankshaft by connecting rod, outputs power.The combustion engine powered loss of this structure is bigger.
Summary of the invention the object of the present invention is to provide a kind ofly can increase substantially engine torque, improve comparatively significantly piston type cyclotomy internal-combustion engine of power performance, oil-saving effect.
For achieving the above object, the technological scheme that the present invention takes is: this piston type cyclotomy internal-combustion engine comprises cylinder, piston, the connecting rod I, crank, cooling system, oil supply system, valve system, lubrication system and the ignition system that are connected with piston, the other end of described connecting rod I is connected with the end of fork I, formed angle is counted pressure angle by acute angle between connecting rod I and the fork I, original state be piston when top dead center position, pressure angle is selected between 0 °-90 °; The coaxial connection of an end of the other end of fork I and fork II, the angle between two forks is arbitrary angle of deciding; The other end of fork II is connected with the end of connecting rod II, and formed angle is counted application angle by acute angle between these two parts, and the original state application angle is selected between 0 °-90 °; The other end of connecting rod II links to each other with crank, drives crank and moves in a circle and output power.
Motion mode of the present invention is: when top dead center, piston begins to move down, and promotes fork I by connecting rod I and does circular motion downwards; Fork I is coaxial with fork II, also does corresponding circular motion thereby drive fork II; Fork II is connected with connecting rod II, drives crank by connecting rod II and does clockwise circular movement.When piston runs to lower dead center, the corresponding circumference summit (180 °) that rotates to of crank, at this moment crank still moves in a circle forward, changes direction thereby promote fork II, moves upward; Drive fork I simultaneously and also upwards do corresponding sports, promote piston by connecting rod I and move upward.During to top dead center, piston is finished a to-and-fro motion; Fork I, fork II finish a deflection period; Crank is finished rotatablely moving the cycle of a circumference.And so forth, finish air-breathing, compression, outburst, the exhaust process of internal-combustion engine in succession, throw crank is done continuous circular movement, outputs power.
In movement process, pressure angle and application angle are respective change, but initial conditions, promptly piston is when top dead center position, and the number of degrees size of pressure angle and application angle is with the fundamental quantity of decision power size variation in transmittance process.During original state, pressure angle should select to determine (by acute angle) between 30-90 °.Application angle should select to determine (by acute angle) between 0-60 °.After application angle was determined, the amplitude of two forks swing was that pivot angle is determined thereupon, was: pivot angle=180 °-2 * application angle, the angle of fork I and fork II is promptly decided the angle, can determine arbitrarily that between 0-360 ° this angle will determine the orientation of crankshaft, that is the basic shape of decision internal-combustion engine casing.This angle determines that the back is a fixed angles, and being in operation no longer changes.The length ratio of fork I, fork II, crank three's length ratio and connecting rod I, connecting rod II is decided on design requirement, and wherein: length is than fork I: fork II＜1.Cylinder position is restricted by crankshaft no longer, can decide according to design requirement.The crank sense of rotation also can be counterclockwise, specifically decides on design requirement.
The present invention makes motive force that very big increase be arranged owing to used application angle, and the effect distance of corresponding power will shorten.Through estimation, total active force still increases, and especially moment of torsion is improved largely, and power increases to some extent, and oil-saving effect is comparatively obvious.
