Device for preparing, storing and feeding vehicle-mounted hydrogen/oxygen and control method thereof

Abstract

The invention discloses a device for preparing, storing and feeding vehicle-mounted hydrogen / oxygen and a control method thereof, particularly relating to prepare, store and feed the hydrogen and the oxygen on a vehicle. In the system, based on reserving an engine storage battery, a vehicle-mounted hydrogen and oxygen preparing device, a hydrogen and oxygen storing device, a hydrogen and oxygen preparing, storing and electronicaly control unit are increased, wherein, according to an accumulator voltage signal, and a hydrogen and oxygen storage tank pressure signal, the electronicaly control unit controls opening and closing of a hydrogen and oxygen preparing machine switch relay, an oxygen tank unidirectional gas discharging valve, an oxygen supply linear solenoid valve and a hydrogen supply pipeline solenoid valve, thus realizing the preparation, storing, feeding, and controlling of the hydrogen and the oxygen on the vehicle. The system has the advantages of realizing the preparation and storing of the hydrogen and the oxygen on the vehicle, ensuring that the vehicle can utilize the hydrogen and the oxygen prepared by the system in the last-time operation when in cold starting, so as to realize the starting of pure hydrogen or pure hydrogen-oxygen gas mixture for the increasing of the hydrogen and oxygen storing device, thereby greatly reducing HC and CO emission when a gasoline engine is started.

Description

technical field [0001] The invention provides a vehicle-mounted hydrogen / oxygen production, storage and supply device and a control method thereof, specifically relating to the vehicle-mounted production, storage and supply of hydrogen and oxygen. Background technique [0002] With the decrease of petroleum resources and the seriousness of automobile exhaust pollution, improving the thermal efficiency of internal combustion engines and reducing harmful emissions have become one of the important issues that need to be solved in the development of internal combustion engines today. Since the diffusion and combustion speed of hydrogen is higher than that of gasoline, the intake hydrogen mixture can effectively shorten the combustion duration of the engine, thereby improving the thermal efficiency of gasoline engines and reducing HC and CO emissions. At the same time, the wide combustion boundary and low ignition energy of hydrogen also enable the hydrogen-mixed internal combust...
