Ammonia-hydrogen fusion engine system and control method thereof

Abstract

The invention belongs to the technical field of clean energy, and particularly relates to an ammonia-hydrogen fusion engine system and a control method thereof.The ammonia-hydrogen fusion engine system comprises an engine, a liquid ammonia vaporization device and an ammonia reaction hydrogen production device, the engine is provided with an intake manifold and an exhaust manifold, and the exhaust manifold penetrates through the ammonia reaction hydrogen production device; the liquid ammonia vaporization device is communicated with the ammonia reaction hydrogen production device through a first pipeline and is communicated with the intake manifold through a second pipeline, and the second pipeline is communicated with the first pipeline so as to convey ammonia gas to the ammonia reaction hydrogen production device and the intake manifold respectively; and a gasoline injector is further arranged on the intake manifold, and when the water temperature of the engine is smaller than a first temperature threshold value or the temperature of a catalyst in the ammonia reaction hydrogen production device is smaller than a second temperature threshold value, the gasoline injector is used for injecting gasoline into the intake manifold so as to start the engine. The cold start problem of the engine can be solved, and the ignition reliability is improved.
