Abstract

The invention discloses an oxygen concentration monitoring method, device and equipment and a storage medium. The oxygen concentration monitoring method specifically comprises the steps that a controller receives a starting command, and enters a set working mode according to the starting command, wherein the set working mode comprises any one of a working mode I, a working mode II and a working mode III; the controller controls an actuator in the set working mode according to the monitored oxygen concentration; and under the condition that the controller determines that the load of an engine is stable, the controller switches the control mode in the set working mode. Through the implementation mode, the working mode of a whole system can be flexibly controlled based on actual requirements,the oxygen concentration of gas is adjusted, and the combustion rate of the gas is ensured.

Description

Technical field[0001]The present application embodiments relate to the field of engine electronic control technology, and more particularly to an oxygen concentration monitoring method, apparatus, device, and storage medium.Background technique[0002]In the low-speed engine of the marine, it is limited by the gas reaction activity. The double fuel machine is forced to use a lower compression ratio, but in this way, the thermal efficiency in diesel mode is low, and the low-speed engine is limited by the structural and intensity limit, the variable compression ratio The technology is not mature, so by controlling the oxygen concentration in the gas tank in gas, it is mainly to become a main solution, for example, the dynamic control oxygen concentration in the prior art (Dynamic Combustion Control-Oxygen, DCO) system. The implementation principle of the DCO system is to introduce the compressor of the host supercharger by combining the exhaust gas generated by the partial double fuel h...
