Double-sparking-plug mixed fuel rotor engine and control method thereof

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...

AI Technical Summary

Problems solved by technology

However, the rotary machine also has problems such as poor fuel economy and high emissions. The main reason for these problems is that the long and narrow combustion chamber structure of the rotary machine is not conducive to the rapid and complete combustion of fuel, and the high surface-to-volume ratio increases the problem of wall quenching. , and the line sealing form leads to a higher air leakage rate, etc.
