Embodiment Construction

[0066] High compression ratio fuel integrated engine

[0067] The implementation example of the scheme of the present invention is a high compression ratio fuel oil integrated engine, that is, a reciprocating piston engine with a compression ratio of more than 30 and various fuels can be used respectively. The specific design and manufacturing method of this example is that on the basis of the existing supercharged diesel engine, the piston and fuel injection are designed and modified accordingly. The energy structure makes the reciprocating piston engine reach various functions of the scheme of the present invention. The engine adopts aluminum alloy or cast iron body, which can withstand pressure above 11MPa; the piston uses two-stage elastic separated multi-stage elastic variable-length piston; the initial pressure of the first-stage elastic combustion chamber of the piston is set to 9MPa, and the maximum pressure is 10MPa. The compression ratio is 30 (the compression ratio...

Abstract

The invention discloses an elastic lengthened piston and a design manufacturing method thereof. The elastic lengthened piston is of an elastic energy storage structure, the function of the elastic lengthened piston is energy storage and rapid elastic potential energy conversion, and rapid energy conversion of internal energy of reciprocating piston type internal combustion engine working media isachieved. The highest temperature and the highest pressure of combustion can be reduced and controlled, the compression ratio of an internal combustion engine can be greatly improved, the heat efficiency of the internal combustion engine is greatly improved, and the mechanical efficiency is effectively improved. Emission of harmful substances can be greatly reduced, the dynamic performance, powerand the power per liter of the internal combustion engine can be greatly improved, the unit displacement machine body mass is effectively reduced, the power mass ratio is improved, a reciprocating piston type fuel integrated engine can be even achieved, various fuel can be used, and new and wide prospects are provided for application of the reciprocating piston type internal combustion engine andvarious fuel.

Description

technical field [0001] The invention relates to a reciprocating piston internal combustion engine, in particular to a piston of the reciprocating piston internal combustion engine. Background technique [0002] The internal combustion engine is a heat engine in which the fuel is burned inside the machine and the energy is converted into power to do work externally; the reciprocating piston internal combustion engine refers to the reciprocating linear motion of the piston in the cylinder, the piston pin is connected with the connecting rod, the connecting rod pushes the crankshaft to rotate, and the piston The linear motion of the crankshaft is converted into a piston internal combustion engine that rotates the crankshaft; the reciprocating piston engine is the most commonly used engine, and the internal combustion engine described below generally refers to the reciprocating piston engine. Reciprocating piston engines can be divided into ignition type and compression ignition...
