Exhaust structure of rotary piston type internal combustion engine

Abstract

The invention discloses an exhaust structure of a rotary piston type internal combustion engine. The exhaust structure comprises a box body consisting of a first mechanism, a second mechanism and a middle mechanism, as well as an eccentric shaft, wherein the middle mechanism is arranged between the first mechanism and the second mechanism; the eccentric shaft passes through the box body, and is connected with a flywheel at the driving end; a piston device is arranged in the middle mechanism, is meshed with an internal gear through a pinion arranged on the piston device to be fixed to the box body, and is arranged at the bearing point position of the eccentric shaft; the outer contour of the piston device comprises even bosses defined by epitrochoids of long and short axles; an inner contour corresponding to the middle mechanism comprises odd reverse bosses defined by enveloping curves formed by the piston device, and the number of the reserve bosses is one more than that of the bosses of the piston device. The exhaust structure has the beneficial effects that a special hot waste gas exhaust system is adopted, and the exhaust structure has no requirement on large structural sizes, is wide in adaptability, and can be suitable for internal combustion engines provided with single pistons or internal combustion engines provided with a plurality of pistons.

Description

technical field [0001] The invention relates to a mechanism for exhausting internal combustion gas with a rotary piston arrangement, in particular to an exhaust structure of a rotary piston internal combustion engine. Background technique [0002] Research on internal combustion engines in recent years has mainly focused on trying to reduce the pollutant components in the exhaust gases or eliminate them completely, either by improving the combustion process of the internal combustion engine or by installing devices such as catalysts connected after the combustion chamber to clean the exhaust gases To create a good environment requires complete combustion of the gases in the combustion chamber, an internal combustion engine with a rotary piston structure seems to be the most promising device, since the combustion chamber can be made to have any desired shape. This is a real internal combustion engine with a rotary piston arrangement, as described above, characterized by a cam...
