Swing arm cam type two-stroke direct shaft internal combustion engine

Abstract

A swing arm cam type two-stroke straight-shaft internal combustion engine, which is a further improvement on the basis of the 346 swing arm two-stroke straight-shaft internal combustion engine. It consists of a single-track elliptical cam on the straight shaft and a single arc slide on the swing arm Coordination replaces the complex operation mode of 346 swing arm double rails connecting and cooperating with each other. The machine runs in continuous contact during one revolution, the operation stability of the machine is increased and the operation noise is completely eliminated. The manufacturing process of the core components of the machine is greatly simplified. The manufacturing cost is further greatly reduced, the force arm of the elliptical cam is further lengthened, and the mechanical efficiency is further improved. At the same time, for 4 models in the one-unit series and 3 models in the two-unit series, the improvement of the single-track elliptical cam and the single-arc slideway swing arm has been made. Compared with the internal combustion engine with the same volume crankshaft, the mechanical efficiency is increased by 3-6 times, and the weight of the machine body is reduced by 3-6 times.

Description

technical field [0001] The invention relates to a swing arm cam type two-stroke straight-axis internal combustion engine. The piston connecting rod pushes the arc-shaped slide on the swing arm to cooperate with the elliptical cam on the straight shaft, so that the linear reciprocating motion of the piston is transformed into the circular motion of the straight shaft. device. [0002] technical background [0003] The direct-shaft internal combustion engine has been invented and manufactured among the people for many years, and there are also many forms in the manufacturing process, but there is no practical successful case so far. The applicant submitted a frame-toothed straight-shaft internal combustion engine on December 8, 2014. The application number is: 201410735070.1. At present, the invention patent authorization has been obtained. This internal combustion engine has been successfully launched through the mutual connection and cooperation of two tracks. It is running,...

The applicant submitted a frame-toothed straight-shaft internal combustion engine on December 8, 2014. The application number is: 201410735070.1. At present, the invention patent authorization has been obtained. This internal combustion engine has been successfully launched through the mutual connection and cooperation of two tracks. It is running, but its biggest defect is that when the connecting rod pushes the gear frame downward at the moment of fuel explosion, the direction of the gear frame arc point to push the special-shaped tooth to run upward is opposite. Once the fuel explosion occurs, the contact point will produce resistance such as friction and sticking , has a great influence on the output efficiency

In response to the above-mentioned defects, the applicant submitted the 346 swing arm two-stroke straight-axis internal combustion engine on June 15, 2018. The application number is: 201810617299.3. The application is currently in the substantive examination stage. Although this internal combustion engine overcomes the The arc point of the gear frame of the straight-axis internal combustion engine pushes the defect of the special-shaped gear to run in reverse, and the efficiency has also been greatly improved, and the number of intermittent connection points has also been reduced from 5 to 3, but it still uses the operation mode of two tracks connecting with each other , although the manufacturing process of the machine is much reduced compared with the crankshaft internal combustion engine, compared with the frame-toothed direct-shaft internal combustion engine with two tracks connected to each other, the manufacturing process of its core components is not much reduced, and the machine's running stability is also lacking.
