Embodiment Construction

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

[0019] Such as figure 1 Including: 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), exhaust gas circulation valve (13), condenser (12), temperature sensor (8), oxygen concentration sensor (7), pressure-stabilizing mixing tank (6), oxygen comes out of the oxygen storage tank (11) After passing through the oxygen pipeline pressure reducing valve (10) and the oxygen flow regulator (9) successively, it is mixed with the circulating exhaust gas and passed through the pressure-stabilizing mixing tank (6) and then enters the combustion chamber through the air inlet. The gas flow rate is also installed on the exhaust pipe regulator (15). ECU (4) controls engine ignition thro...

Abstract

The invention designs a hydrocarbon fuel ignition type zero nitrogen rotor machine with oxygen as an oxidant and a control method of the hydrocarbon fuel ignition type zero nitrogen rotor machine. A fuel flow meter (3), an oxygen flow adjuster (9) located in an oxygen conveying pipeline and a gas flow adjuster (15) are adjusted by using the rotating speed of an engine as a signal and combining signals of an oxygen concentration sensor (7) and a CO concentration sensor (14), the peroxygen concentration coefficient of the rotor engine is maintained in an appropriate range, the combustion efficiency of the engine is improved, nitrogen in intake air is removed in a pure oxygen intake method, emission performance of the rotor machine is improved, and zero nitrogen emission of the rotor machineis achieved. Since the device adopts the clean oxidant, the defect that nitrogen in intake air generates nitrogen oxides (NOx) in the high temperature environment in a cylinder of a traditional engineis overcome, and therefore zero emission of the engine is achieved.

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 ...
