Abstract

The utility model relates to a colliding piston internal combustion engine which belongs to the technical field of reciprocating piston internal combustion engines. A complete machine is formed by the corresponding assembly of a cylinder body of a left sub machine, a cylinder body of a right sub machine, and a middle sharing cylinder body, wherein crank link mechanisms of the left and the right sub machines realize synchronous work through a timing gear and do reciprocating movement in opposite moving directions in the middle sharing cylinder body, which causes that working medium expands for work in a sharing combustor of the middle part of a cylinder for simultaneous work circulation. The utility model has a high heat efficiency and mechanical efficiency, and the utility model can be used in the fields of motor vehicles, ships, and diesel locomotives using internal combustion engines.

Description

The collision type piston IC engine

The collision type piston IC engine belongs to the internal-combustion reciprocating-pisto technical field.

Over more than 100 year,, and constantly improving and developing though piston IC engine has reached very high technical merit.According to reference; " heat dissipating capacity of diesel engine about 30% is absorbed by the cooling system of cylinder head " that weapon industry the 70 research laboratory " turbosupercharging and turbosupercharger " literary composition is pointed out; Diesel engine 97.6。" 485Q Q Diesel Engine Ceramic vortex chamber's structural design and performance test research " literary composition is pointed out: " reduce the thermal loss of firing chamber, reduce the heat that cooling water is taken away.Help improving the thermal efficiency of motor." existing internal-combustion reciprocating-pisto all adopts overhead cylinder head technology, the problem that the ubiquity thermal efficiency and mechanical efficiency are difficult to improve again.

The purpose of this utility model is to propose the collision type piston IC engine.

The mentality of designing of collision type piston IC engine of the present utility model is: will remove left handset cylinder block and the right handset cylinder block and the middle shared cylinder block of cylinder head, the main body of three horizontal bodies of the corresponding fastening formation of combination of major component.In the cylinder of the middle part of horizontal body, form combustion chamber shared, be provided with shared overhead cylinder head at combustion chamber shared top, shared overhead cylinder head is provided with air distributing device and supplier, is provided with synchronous timing gear at the handset crankshaft output end of body rear end.By adopting the relative effective work done area that increases in the cylinder of shared overhead cylinder head with combustion chamber shared technology, reduce the approach of combustion chamber heat loss, improve the thermal efficiency and the mechanical efficiency of internal-combustion reciprocating-pisto.The concrete practice is the corresponding surface with piston in the cylinder of internal-combustion engine--the internal surface of-cylinder head, change the energy conversion device---piston that becomes effective work done, and formed combustion chamber shared.Working medium burning expansion in combustion chamber shared promotes the connecting rod of the corresponding group of left and right handset and makes the opposite to-and-fro motion of moving direction, the work cycle of carrying out synchronous timing.Connecting rod is made the mechanical work to even balance in cylinder, carry out the double energy conversion, thereby improves the utilization ratio of energy in the working medium.The requirement of timing is synchronously determined by synchronous rotor timing gears.Air distributing device and supplier are located on the shared cylinder head of cylinder block middle part upside, and other peripheral unit of body are similar to the relevant device of existing internal-combustion reciprocating-pisto.The collision type piston IC engine is actual to be after a kind of left and right two piston IC engine handsets correspondence makes up, to use the same firing chamber in the cylinder jointly, and synchronous working circuit internal-combustion reciprocating-pisto is carried out in parallel operation.
