Title:
THERMAL DECOMPOSITION AND HIGH-PRESSURE DIRECT INJECTION TYPE AMMONIA-FUELLED ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/151121
Kind Code:
A1
Abstract:
A thermal decomposition and high-pressure direct injection type ammonia-fuelled engine, comprising an ammonia storage tank, an ammonia booster pump, an ammonia preheating and decomposition device, a high-pressure injection valve, a nozzle, an engine body and a tail gas treatment device. After being pressurized, low-temperature and low-pressure ammonia enters the ammonia preheating and decomposition device heated by exhaust gas, and is decomposed to produce an ammonia-hydrogen-nitrogen mixed fuel. After passing through the high-pressure injection valve, said mixed fuel enters the engine body for combustion work. Engine exhaust gas passes through the ammonia preheating and decomposition device so as to recover part of heat energy and then is discharged. Energy of the exhaust gas is recovered by utilizing the characteristics of the ammonia fuel, thereby improving the efficiency of an internal combustion engine, and solving the problems of difficulty in ignition and the like.
