Example Embodiment

[0023] The present invention will be further explained below in conjunction with the drawings and specific embodiments:

[0024] Figure (1) includes: hydrogen storage tank (1), after the hydrogen comes out of the storage tank, it passes through the pressure reducing valve (6), hydrogen flow meter (7), flame retardant valve (8), and then installed in the combustion chamber The hydrogen nozzle (9) on the wall enters the rotor machine for combustion. The spark plug (3) and the spark plug cylinder pressure sensor (4) are respectively connected in series with the first charge amplifier (2) and the second charge amplifier (5) and then installed in parallel. On the wall of the combustion chamber, the ECU (10) sends an ignition signal to the first charge amplifier (2) and the second charge amplifier (5) to ignite the spark plug according to the engine working conditions. An air flow meter ( 13) Monitor the intake pressure and temperature. After the gasoline comes out of the storage tank ...

Abstract

The invention provides a double-sparking-plug mixed fuel rotor engine and a control method of the double-sparking-plug mixed fuel rotor engine. After coming out of a storage tank, hydrogen sequentially passes through a pressure reducing valve, a hydrogen flow meter and an inflaming retarding valve and then enters the rotor engine to be combusted from a hydrogen spray nozzle on the wall face of a combustion chamber. After coming out of a storage tank, gasoline passes through an oil pump and an oil consumption meter and then enters an air intake channel from an oil spray nozzle installed on theair intake channel, and the oil enters the combustion chamber to be combusted along with the intake air. An ECU controls sparking plugs to conduct ignition according to the work condition of the engine. A hydrocarbon concentration sensor located on an exhaust channel detects the hydrocarbon concentration in exhausted gas and sends the hydrocarbon concentration signal to the ECU. According to the double-sparking-plug mixed fuel rotor engine and the control method of the double-sparking-plug mixed fuel rotor engine, the rotation speed of the engine and the opening degree of a throttle valve areused as signals, in combination with the signals of the hydrocarbon concentration sensor and an air flow meter, the hydrogen spray time and amount are controlled, the combustion efficiency of the rotor engine is improved by means of the double-sparking plug structure, and emission of harmful matter is lowered.

Description

technical field [0001] The invention provides a dual-spark plug mixed fuel rotor machine and a control method thereof. The invention relates to the supply and ignition mode of the dual fuel of the rotary engine, and belongs to the category of the internal combustion engine. 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 large power-to-weight r...
