Piston type double-stroke engine with fuel choosable

Abstract

The invention discloses a piston type double-stroke engine with fuel choosable. According to the piston type double-stroke engine with the fuel choosable, the technical characteristics of a combustion gas turbine, the good airtightness of the piston set and the cylinder of a four-stroke piston type engine and the advantages of the double-stage piston type pressurizing device and the electric pressurizing device of an exhaust-driven gas turbine are integrated, a piston type double-stroke acting method with two sixths of the piston stroke for air inflow and four sixths of the piston stroke for acting and waste gas exhausting is utilized, the problems of uneven operation of the four-stroke piston type engine and the like are solved, and the range of the usable fuel of the piston type double-stroke engine with the fuel choosable is widened. Compared with the four-stroke cylinder piston type engine, the piston type double-stroke engine with the fuel choosable has the advantages that the power of the piston type double-stroke engine with the fuel choosable is more than twice of that of the four-stroke engine on the premise that the size and the weight of the piston type double-stroke engine with the fuel choosable are the same as those of the four-stroke engine, and the piston type double-stroke engine with the fuel choosable is more powerful.

Description

Technical field [0001] The invention relates to a new type of engine, especially compared with the four-stroke engine technology, the optional fuel piston type two-stroke engine with equal weight and volume has twice the power of the four-stroke piston engine, and the engine not only overcomes the low thermal efficiency It also overcomes the uneven operation of the four-stroke piston engine and the limitation of a single fuel, which provides a feasible solution for improving the thermal efficiency of the engine, improving energy saving and emission reduction, and widening the use of fuel. Background technique [0002] 1. The four-stroke piston engine of prior art all needs to have: [0003] 1) Only by overcoming the three discontinuous processes of exhaust, air intake, and compression can a work process be completed. The discontinuity of work and the loss of power in the two strokes of intake and compression have always been insurmountable for four-stroke engines in the prio...

Problems solved by technology

[0004] 2) In addition, all four-stroke engines must limit the limitations of using a single fuel;

[0006] 1) From the perspective of aerodynamics: the efficiency of the compressor and the turbine (the air tightness between the turbine blade and the wall of the working chamber is poor, which causes too much loss of gas) is too low, only 65% ​​and 70%, even the turbine The power is not enough to meet the power consumption needs of the compressor

[0007] 2) From a metallurgical point of view: it is impossible to provide a heat-resistant turbine alloy that can work reliably at a gas temperature above 1300-1700 °C

[0008] These two kinds of engines have caused the insurmountable defects such as large environmental pollution, large loss of energy and poor power and poor economy of the engine when running at a low speed.
