Embodiment Construction

[0015] The present invention will be described in more detail below in conjunction with the accompanying drawings:

[0016] combine figure 1 , The structure of the zero-carbon combustion test bench for an ammonia / hydrogen mixed fuel engine ignited by hydrogen includes: intake pipeline I1, heating resistance wire 2, compressor 3, turbine 4, intake pipeline II5, thermometer 6, engine 7, exhaust gas Pipeline 8, hydrogen storage tank 9, ammonia storage tank 10, flowmeter I11, flowmeter II12, flowmeter III13, fuel supply pipeline I14, fuel supply pipeline II15, fuel injector I16, fuel injector II17. The air enters the compressor 3 through the heating resistance wire 2 through the intake pipeline I, and the compressor 3 is connected to the engine 7 through the intake pipeline II. The temperature of the intake air can be measured by the thermometer 6 in the intake pipeline II, and then the heating resistance The wire adjusts the intake air temperature, the engine 7 is connected to t...

Abstract

The invention aims to provide a hydrogen ignited ammonia-hydrogen mixed combustion zero-carbon engine and a control method, the hydrogen ignited ammonia-hydrogen mixed combustion zero-carbon engine comprises an engine, an ammonia storage tank and a hydrogen storage tank, the hydrogen storage tank is connected with a second oil supply pipeline through a first flowmeter, the second oil supply pipeline is connected with a second oil sprayer of the engine, and the ammonia storage tank is connected with a first oil supply pipeline through a third flowmeter. The first oil supply pipeline is connected with a first oil injector of the engine, and the hydrogen storage tank is connected with the first oil supply pipeline through a second flowmeter. According to the method, practical application of NH3/H2 fuel on the high-pressure common rail diesel engine can be promoted, data support is provided for the hydrogen compression ignition engine, development of the hydrogen compression ignition engine is promoted, and the method has great significance in achieving the zero-carbon emission target of carbon neutralization.

Description

technical field [0001] The present invention relates to an engine and a control method thereof, in particular to an ammonia-hydrogen engine and a control method thereof. Background technique [0002] Global demand for fossil energy continues to increase, greenhouse gas emissions worsen when fossil fuels are burned, icebergs in the Arctic and Antarctic are decreasing, permafrost is melting, sea levels are rising, many non-renewable energy sources have entered a state of scarcity, and global warming is intensifying. In order to limit greenhouse gas emissions and prevent further global warming, industries, shipping, automobiles and other industries must be decarbonized. The use of renewable low-carbon or carbon-free alternative fuels for diesel engines is the most effective solution to achieve zero carbon emissions. Today, many renewable low-carbon energy sources have been widely studied and applied to engines, such as methanol, butanol, dimethyl ether, methyl ethyl oxalate, bi...
