Side-by-side type rotary piston internal combustion engine

Abstract

The invention provides a side-by-side type rotary piston internal combustion engine and belongs to the technical field of reciprocating piston type internal combustion engines. Referring to a figure (4), the side-by-side type rotary piston internal combustion engine comprises a main shaft 1, a clamping plate 2, a right end cover 3, an air guide plate 4, a public end cover 5, a nut 6, a bolt 7, a compression cylinder 8, an acting cylinder 9 and a left end cover 10. The main technical characteristics of the side-by-side type rotary piston internal combustion engine are that one cylinder completes air intake and compression, the other cylinder completes acting and exhausting, the two cylinders are connected side by side, and the well compressed air is conveyed to the acting cylinder in time through the rotating air guide plate between the two cylinders so that acting and exhausting can be completed. The side-by-side type rotary piston internal combustion engine has the advantages that during acting, high-pressure air can directly push the main shaft to rotate, the fuel efficiency is greatly improved, and the size is reduced; under the condition of the same output torque or the same power, the cylinder capacity can be reduced by 30% or over, and the size can be reduced by 50% or over; and an intake hole and an exhaust hole are normally open, additional arrangement of an air distributing mechanism is not needed any more, and other performances are all superior to those of the reciprocating piston type internal combustion engine.

Description

technical field [0001] The invention belongs to the technical field of reciprocating piston internal combustion engines, and more specifically relates to a parallel rotary piston internal combustion engine. Background technique [0002] The reciprocating piston internal combustion engine (gasoline engine, diesel engine) occupies the first place in power machinery and is widely used in the fields of automobiles, agricultural machinery, construction machinery, ships, tanks, helicopters and other light aircraft. From the design point of view of the reciprocating piston internal combustion engine, there are still three major problems: [0003] 1. Valve type gas distribution mechanism [0004] During the intake process of the valve-type valve mechanism, the charge coefficient and the intake flow rate are mutually restricted. The higher the intake flow rate, the smaller the charge coefficient, which is inversely proportional. When the average flow rate of intake air exceeds Mach...

AI Technical Summary

Problems solved by technology

The main disadvantage of this is that it is difficult to use the kinetic energy of the intake airflow to form a gas movement form and intensity in the cylinder that meets the actual needs of emission reduction, which is not conducive to the formation and combustion of the mixture and the reduction of PM emissions.

At the same time, multi-valve valve distribution makes the structure more complicated, which greatly increases the manufacturing cost of the valve mechanism

[0005] 2. The problem of residual exhaust gas

However, when it is used in an internal combustion engine to form a reciprocating piston internal combustion engine, it brings great disadvantages

It is mainly manifested in the process that the piston makes reciprocating linear motion and drives the crankshaft to rotate through the connecting rod, which will generate a large lateral force and inertial force that are not conducive to the rotation of the crankshaft, resulting in great waste and increased Reduce the wear of piston and cylinder liner, the vibration and noise of the whole machine

Simultaneously because of the reason of the crank connecting rod mechanism, the volume of the whole internal combustion engine is relatively large.
