Device and method for producing oxyhydrogen through vehicle-mounted oxyhydrogen producer using residual electricity supplied by internal combustion engine

Abstract

The invention relates to a device and method for producing oxyhydrogen through a vehicle-mounted oxyhydrogen producer using residual electricity supplied by an internal combustion engine. The system keeps the entire main body and a control system of the original internal combustion engine, one set of vehicle-mounted oxyhydrogen producer control system and one set of oxyhydrogen production, storage and supply system are added. The device mainly comprises the vehicle-mounted oxyhydrogen producer, a hydrogen storage tank, a hydrogen pressure reducer, a hydrogen flame retarding valve, an oxygen storage tank, an oxygen pressure reducer, an oxygen flame retarding valve, a storage battery loop relay connected between the engine and a storage battery, an oxyhydrogen producer loop relay connected between the engine and the oxyhydrogen producer, an electronic control unit and the like, wherein the hydrogen storage tank, the hydrogen pressure reducer and the hydrogen flame retarding valve are connected with a hydrogen outlet of the vehicle-mounted oxyhydrogen producer; and the an oxygen storage tank, the oxygen pressure reducer and the oxygen flame retarding valve are connected with an oxygen outlet of the vehicle-mounted oxyhydrogen producer. The electronic control unit controls the operation of the oxyhydrogen producer according to the relationship between the engine and the voltage ofthe storage battery and the pressure of hydrogen and oxygen in the storage tanks, preferably ensures the charge of the storage battery and stops the operation of the oxyhydrogen producer when the gases in the hydrogen and oxygen storage tanks have overpressure.

Description

technical field [0001] The invention provides a device and control method for a vehicle-mounted hydrogen and oxygen generator to produce hydrogen and oxygen by using the residual power of an internal combustion engine, and the specific content relates to a device for producing, storing and supplying hydrogen and oxygen based on a vehicle-mounted hydrogen and oxygen generator using excess electric energy of the internal combustion engine and control methods. Background technique [0002] Gasoline and diesel internal combustion engines often produce a large amount of harmful emissions during operation. At the same time, the dwindling of oil resources has also made it an inevitable trend to improve the thermal efficiency of internal combustion engines. Compared with traditional gasoline and diesel fuel, hydrogen has many excellent combustion and physical and chemical characteristics such as low ignition energy, fast combustion speed, and wide lean burn boundary. Therefore, mi...
