Four-cylinder spherical internal combustion engine main body mechanism

Abstract

The invention relates to a main mechanism for a four-cylinder spherical internal combustion engine, comprising a spherical casing having two ends provided with bearing seats. A partition circular ring which has an angle between 35 and 55 degrees with a connecting line of center through holes of the bearing seats at two ends is arranged inside the spherical casing; the upper or lower part of the spherical casing is provided with an air inlet and an exhaust port corresponding to two sides of a partition rotary plate; the middle part inside the partition rotary plate body is provided with a spherical-like rotary piston; two end parts of the axial lead of the rotary piston body are hinged with the partition rotary plate; two sides of the rotary piston are symmetrically connected with piston petal sheets, so as to ensure that air cavities positioned on two sides of the partition rotary plate form four working air chambers; a built-in circular rotary plate is arranged in a seam mouth on the middle part of the rotary piston; two ends of the built-in circular rotary plate are fixed with a main journal running through a bearing seat hole of the casing; two air ducts are symmetrically arranged on the built-in circular rotary plate; the piston petal sheets are respectively provided with through holes of four air ducts corresponding to the four working air chambers; and a spark plug extending into the spherical casing is arranged on the spherical casing. The main mechanism not only can be used for manufacturing an internal combustion engine with a new working form, but also is compact in structure and few in parts.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a main body mechanism of a four-cylinder spherical internal combustion engine. Background technique [0002] At present, the widely used engine uses the reciprocating linear motion of the piston to compress the combustible gas, and then ignites the gas to generate a large amount of heat energy in an instant. By pushing the piston, the heat energy is converted into mechanical energy, and then the crankshaft is used to output torque. Since the crankshaft has a dead point when it is doing circular motion, and the reciprocating linear motion of the piston has a great impact, it is necessary to arrange multiple cylinders to work at the same time, resulting in complex motion mechanisms, many parts, and very difficult processing and control. The utilization rate is low, and the engine efficiency is also low. For triangular rotor engines, since the sealing pins in contact betw...

Problems solved by technology

Since the crankshaft has a dead point when it is doing circular motion, and the reciprocating linear motion of the piston has a great impact, it is necessary to arrange multiple cylinders to work at the same time, resulting in complex motion mechanisms, many parts, and very difficult processing and control. Low utilization and low engine efficiency

For triangular rotor engines, since the sealing pins in contact between the triangular rotor and the bottom surface of the cylinder are double-sided contact working surfaces, the sealing work is poor, and the requirements for sealing and lubrication conditions are very high, and the requirements for materials are also very strict. At the same time, the inner surface of the cylinder and the triangular The outer surface of the rotor is a special special-shaped curved surface, and the main shaft uses gear wires to output power, which is extremely difficult to process and has not been widely used so far.
