Gasoline and ammonia dual fuel supply device for automobile engine

Abstract

The invention provides a gasoline and ammonia double-fuel supply device for an automobile engine. In the working process, after a power source is engaged, an ammonia generation device is used for electrolyzing to prepare ammonia, and the ammonia is separated by a separator, and is stored into a liquid ammonia tank; or a power source heating method is adopted, the ammonia is decomposed in a waste gas heat exchange ammonia separator to generate hydrogen and nitrogen, the hydrogen is stored into a hydrogen storage tank, and the nitrogen is emptied; in the driving process, the hydrogen separated by the separator or the hydrogen supplied by the hydrogen storage tank, and the ammonia produced by the ammonia heat exchanger or the ammonia heated by the waste gas heat exchange ammonia separator are sent into the air cylinder to combust in a direct injection way in the cylinder; the hydrogen, the ammonia and the gasoline are sent into the air cylinder in the direct injection way in the cylinder, the proportion is adjusted by an ECU (electronic control unit), and finally the engine can realize the effects of optimum combustion and minimum emission. The gasoline and ammonia double-fuel supply device has the advantages that the structure is simple, the excessive use of gasoline fuel can be effectively reduced, and the emission of gases, such as carbon dioxide, can be greatly reduced; a green and environment-friendly automobile fuel supply system is provided.

Description

technical field [0001] The invention relates to a fuel supply device for an engine, in particular to a gasoline and ammonia dual 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 is becoming more and more serious, and the environmental pollution caused by automobile engines is becoming more and more serious. The massive emission of carbon dioxide is one of the main causes of the greenhouse effect, and the emission of harmful substances such as CO and PM is also harmful to the environment. The environment has done a lot of damage. Ammonia is used as a motor fuel, and the combustion product does not contain CO2, which has a positive effect on the improvement of the greenhouse effect and can also reduce people's dependence on non-renewable resources of fossil fuels. [0003] According to the current research status of ammonia fuel, it i...
