Starting cylinder of piston reciprocating internal combustion engine and air exhausting device of starting cylinder of piston reciprocating internal combustion engine

Abstract

The invention discloses a starting cylinder of a piston reciprocating internal combustion engine and an air exhausting device of the starting cylinder of the piston reciprocating internal combustion engine. The starting cylinder and the air exhausting device are mainly characterized in that the mode that an air exhausting opening is formed in a starting cylinder cover plate, namely an engine cover plate, of an existing four-stroke or two-stroke direct current scavenging engine and connected with an air exhausting channel is changed into the mode that the air exhausting opening is formed in the side of a starting cylinder body and connected with the air exhausting channel, and meanwhile a mushroom-shaped vent valve is changed into a gate vent valve; in this way, the problem that a working mechanism must be arranged on the engine cover plate or multiple working parts are difficult to arrange is solved, damage, caused by air exhausting heat loads, to the engine cover plate and the arrangement on the engine cover plate is avoided, and indispensable conditions are particularly created for multiple overhead working systems and an overhead comprehensive regulating and control system which are invented in the ZL200710193939.4 invention with the publication patent number CN101205861B and a novel piston reciprocating internal combustion engine invented in the ZL200710193938.X invention with the publication patent number CN151289956B, wherein according to a pressurizing mechanism combination of the novel piston reciprocating internal combustion engine, energy is greatly saved, stains are greatly removed, and the specific weight of the engine is greatly reduced.

Description

technical field

[0001] The invention belongs to the field of piston reciprocating internal combustion engines, and in particular relates to a starting cylinder of a piston reciprocating internal combustion engine and an exhaust gas arrangement thereof. Background technique

[0002] Existing conventional internal-combustion engine (crank-and-rod mechanism piston reciprocating internal-combustion engine), due to the arrangement of the working mechanism in the overall structure of the engine and the selection of the scavenging mode, the exhaust port of the four-stroke engine and the two-stroke direct-flow scavenging engine starting cylinder, with The fungus valve closely cooperates to realize the work of opening and closing the exhaust port. The connection between the exhaust port and the exhaust pipe is set on the top cover of the engine, occupying the position on the engine cover, and also causing the engine top cover to be damaged. Suffering from severe heat loads. Two-stro...
