A new type of hydrogen-ammonia mixed fuel supply device for automobile engine

Abstract

The invention provides a novel automobile engine hydrogen and ammonia blended fuel supply device, which comprises an ammonia generation device, wherein an external power supply can be used for storing ammonia prepared from electrolysis into a liquid ammonia tank under a general condition of parking; hydrogen produced from ammonia decomposition can also be stored in a hydrogen storage tank, and the ammonia and the hydrogen can be jointly used as engine fuel when an engine works. The device can externally be added with ammonia fuel to guarantee fuel supply. The device is characterized in that catalytic decomposition can be carried out by the exhaust gas heat of the engine or with electric energy heating ammonia to effectively improve heat energy use efficiency; the ammonia and the hydrogen are used as the engine fuel to effectively eliminate the emission of greenhouse gases, such as CO2 and the like and substantially lighten pollution on the environment by harmful emissions, such as CO, PM (Particulate Matter) and the like; the overuse of petroleum can be effectively alleviated, and the blended fuel is used for replacing gasoline to serve as the green environmentally-friend fuel of the automobile. According to the device, the ratio of hydrogen and ammonia fuel can be controlled through an automobile electronic control unit (ECU) to improve engine combustion efficiency, and the ignition reliability of the fuel is extremely high.

Description

technical field [0001] The invention relates to a fuel supply device for an engine, in particular to a novel hydrogen-ammonia mixed fuel supply device for an automobile engine. Background technique [0002] With the continuous development of modern society, the contradiction between the supply and demand of petroleum fuels has become increasingly serious. At the same time, the problem of environmental pollution caused by automobile engines has become increasingly serious. A large amount of carbon dioxide emissions are one of the main causes of the greenhouse effect, and the emissions of harmful substances such as CO and PM are also caused great damage to the environment. Ammonia is used as a motor fuel, and the combustion product does not contain CO2, which has a very positive role in improving the greenhouse effect, and at the same time can reduce people's dependence on non-renewable resources of fossil fuels. [0003] According to the current research status of ammonia fu...
