Abstract

The invention provides a spark ignition type oxyhydrogen gas rotor engine and a control method, in particular to a pure oxyhydrogen gas spark ignition type rotor engine hydrogen and oxygen gas supplysystem and oxygen jetting and lubricating oil jetting control. According to the system, on the basis that original machine main parts are reserved, a burning electronic control unit (12), a lubricating oil spraying nozzle (16), a lubrication oil pump (17), a lubrication oil tank (18), a high pressure oxygen spraying nozzle (7) and a low pressure oxygen spraying nozzle (10) are additionally arranged. The burning electronic control unit (12) can judge the oxygen jetting manner according to needed power signals (e), an engine adopts an air passage for jetting oxygen to improve efficiency under the low power condition, and the engine adopts high pressure oxygen direct jetting to avoid fire return under the medium and high power condition. In order to solve the problem that a gas fuel rotor machine is difficult to lubricate, the burning electronic control unit can control the jetting pulse width of the lubricating oil spraying nozzle (16) according to the actual load of the engine, and efficient lubrication of the engine is guaranteed.

Description

technical field [0001] The invention provides an ignition type rotary engine and a control method using pure hydrogen and pure oxygen as working fluids, and specifically relates to a hydrogen and oxygen supply system and oxygen injection and combustion process control of an ignition type hydrogen-oxygen rotary engine. Background technique [0002] The power system of spacecraft and other devices uses liquid hydrogen as fuel, and converts liquid hydrogen into gaseous hydrogen for use in fuel cells. Since the liquid hydrogen storage device is only concerned with hydrogen leakage, and excess hydrogen will be discharged during the operation of the fuel cell, there is a large amount of residual hydrogen in the device using the above power scheme. Since this part of the remaining hydrogen is in a low-pressure state, it is difficult to be re-pressurized and introduced into the fuel cell for use, and the re-pressurization of this part of the hydrogen requires the compressor to consu...
