Embodiment 1

[0044] Such as figure 1 , 2 shown.

[0045] A method for realizing a stepless speed regulation eccentric swing internal combustion engine comprises the following steps:

[0046] First, make the crank of the internal combustion engine swing eccentrically around a fulcrum on one side of the cylinder axis, as figure 2 shown;

[0047] Secondly, the eccentrically oscillating crank drives the first drive shaft to reciprocate, and at the same time connects the first drive shaft to the second drive shaft through a direction-changing mechanism, thereby alternately driving to ensure that the first drive shaft can have a continuous swing during the reciprocating swing. power output, the first drive shaft and the second drive shaft continuously drive the output shaft through a linkage mechanism with a one-way transmission device for continuous directional output;

[0048] Third, stepless speed regulation is realized by adjusting the crank lengths of the first drive shaft and the sec...

Embodiment 2

[0051] Such as image 3 , 4 , 5, and 6.

[0052] An eccentric oscillating internal combustion engine with a pulsating stepless speed regulation transmission, comprising an internal combustion engine body and a transmission device connected to the internal combustion engine body, wherein the internal combustion engine body further includes a cylinder and a piston located in the cylinder, the piston is connected with a connecting rod, and the The connecting rod is connected to the crank that swings around the fulcrum, the crank is connected to the input shaft of the transmission device, and the output shaft of the transmission device is connected to the driven parts. The transmission device is a pulse type stepless speed regulating device; the pulse type The stepless speed regulating device includes two coaxial first drive shaft 1 and the second drive shaft 2, the first drive shaft 1 and the second drive shaft 2 serve as the input shaft of the pulsating stepless speed regulatin...

Embodiment 3

[0067] As shown in Figure 7.

[0068] A transmission device (Fig. 7) of a four-stroke four-cylinder single-row internal combustion engine contains cylinders P1, P2, P3, P4 numbered according to their working order. The pulsating stepless speed regulating device is installed in the transmission device in the following manner; cylinders P4 and P2 are located on one side of the pulsating stepless speed regulating device, and cylinders P1 and P3 are located on the other side. The drive shaft 1 and 2 of the pulsating stepless speed regulating device are connected with the common connecting rod 3 and the swing crank 4, and the swing range of the crank 4' is α=90°.

[0069] In order to drive the flywheel 26 (without which the internal combustion engine cannot work), there is a crank rocker mechanism, which is connected to the input shaft 1, the transmission ratio of this mechanism is determined in the following way: when the rocker arm 27 swings from one extreme position to the other...

Abstract

The present invention relates to a method and a device for realizing stepless speed regulation of an eccentrically oscillating internal-combustion engine. The device comprises an internal-combustion engine body and a driving device connected with the internal-combustion engine body, wherein the internal-combustion engine body comprises a cylinder and a piston in the cylinder; and the piston is connected with a connection rod. The device is characterized in that the connection rod is connected with a crank swinging around a fulcrum; the crank is connected with an input shaft of the driving device; an output shaft of the driving device is connected with a driven component; and the driving device is a pulsing stepless speed regulation device. The method and the device can lower the friction force of the piston to the cylinder wall by multiple times, obviously reduce fuel consumption, lower heating strength of engine components and lower abrasion of piston parts by multiple times. The driving device obviously reduces outline size, weight and cost, and can reduce the cost by more than 20 percent under the same conditions.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to an internal combustion engine that swings through a crank and adopts a pulsating continuously variable speed, in particular a method and device for realizing a stepless speed regulation eccentric swing type internal combustion engine. Background technique [0002] As we all know, most automobiles adopt step transmission, which is realized through the step-by-step adjustment of the gearbox. For example, the number of stages of the gearbox on a light-duty car is usually 4-6. Similar graded speed regulation is actually applied to all trucks and tractors. On agricultural tractors, due to special requirements for speed regulation in production operations, the gearbox often uses 10-18 stages. The limited number of stages in the gearbox causes the engine to be in a non-optimal working state in many cases, causing an increase in fuel consumption. Changing from one gear to the other (fr...
