Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0019] Such as figure 1 It includes: a hydrocarbon fuel storage tank 1, the outlet of the storage tank is connected in series with the oil pump 2, the fuel flow meter 3, and the fuel nozzle 5 installed on the intake passage, and the CO concentration sensor 14 and the exhaust gas circulation valve 13 are sequentially installed on the exhaust pipe of the engine , condenser 12, temperature sensor 8, oxygen concentration sensor 7, and pressure-stabilizing mixing tank 6. After oxygen comes out of the oxygen storage tank 11, it passes through the oxygen pipeline pressure reducing valve 10 and the oxygen flow regulator 9 successively, and is mixed with the circulating exhaust gas through After the pressure-stabilizing mixing tank 6 enters the combustion chamber through the air inlet, a gas flow regulator 15 is also installed on the exhaust pipe. ECU4 contr...

Abstract

The present invention designs a hydrocarbon fuel ignition type zero-nitrogen rotor machine with oxygen as an oxidant and its control method, using the engine speed as a signal and combining the signals of an oxygen concentration sensor (7) and a CO concentration sensor (14) to adjust the fuel flow rate The meter (3), the oxygen flow regulator (9) and the gas flow regulator (15) located in the oxygen delivery pipeline maintain the oxygen concentration coefficient of the rotary engine in an appropriate range and improve the combustion efficiency of the engine. The pure oxygen intake method removes the nitrogen in the intake air, improves the emission performance of the rotary machine, and realizes zero nitrogen emission of the rotary machine. Because the device uses a clean oxidant, it overcomes the shortcomings of nitrogen oxides (NOx) generated by nitrogen in the intake air of a traditional engine in a high-temperature environment in the cylinder; thus realizing zero emission of the engine.

Description

technical field [0001] The invention provides a control method of a hydrocarbon fuel ignition type zero-nitrogen rotor engine using oxygen as an oxidant, relates to a rotary engine pure oxygen combustion and a hydrocarbon fuel supply method, and belongs to the field of internal combustion engines. Background technique [0002] As environmental issues are getting more and more attention from the general public, the monitoring of pollution in various countries is becoming more and more stringent. Automobile exhaust emissions have also been pushed to the foreground in this environment, and countries have introduced relevant regulations one after another to limit automobile exhaust emissions. Therefore, reducing engine fuel consumption and emissions has become a mainstream research direction in the field of internal combustion engines. [0003] Compared with the reciprocating piston engine, the rotary engine has the advantages of small size, light weight, simple structure, and ...
