Abstract

The invention relates to the technical field of ammonia fuel engines, and provides an ammonia-hydrogen fusion type hybrid power system and an engine. The ammonia-hydrogen fusion type hybrid engine includes: a fuel tank for storing liquid ammonia, the fuel tank including a discharge port; the ammonia catalysis hydrogen production device is used for catalyzing ammonia gas to form hydrogen and comprises an ammonia inlet and a hydrogen outlet, and the ammonia inlet is connected with the discharge port; the ammonia fuel engine comprises a main combustion chamber, a jet ignition cavity and an ignition device, the main combustion chamber is connected with the discharge port, the hydrogen discharge port is connected with the jet ignition cavity, the ignition device is arranged in the jet ignition cavity, and the jet ignition cavity is communicated with the main combustion chamber. Combustion hydrogen can form jet flames and enter the main combustion chamber, and ammonia mixed gas is stably ignited. The hydrogen flame jet flow has multiple ignition sites and can form free radicals such as OH <-> with high concentration in the main combustion chamber, the combustion speed of ammonia mixed gas can be increased, and therefore stable ignition and rapid combustion of ammonia gas are achieved.

Description

technical field [0001] The invention relates to the technical field of ammonia fuel engines, in particular to an ammonia-hydrogen fusion type hybrid power system and an engine. Background technique [0002] There are problems to be solved in the application of ammonia gas on the engine. Ammonia has high natural temperature, high minimum ignition energy, and low laminar flame velocity. Therefore, ammonia is a low-reactivity fuel, and its difficulty in ignition and slow combustion velocity are important problems that limit its application in engines. Contents of the invention [0003] The invention provides an ammonia-hydrogen fusion hybrid power system and an engine, which are used to solve the defects of difficult ignition and slow burning speed of ammonia as a low-reactivity dye in the prior art, and realize stable ignition and combustion of ammonia fuel in an ammonia-fueled engine. Burns fast. [0004] An ammonia-hydrogen fusion type hybrid engine provided by the prese...
