Description
Technical Field
The invention relates to an engine device and a combustion method, in particular to a dual-fuel engine device and a combustion method.
Background
Ammonia is a carbon-free compound and does not produce CO when combusted 2 . On the other hand, the yield of ammonia is rich in the world, and the conditions of ammonia production, storage and transportation are relatively mature. In summary, ammonia has great potential as a replacement fuel for fossil energy. Ammonia discharges only water and nitrogen when completely combusted in oxygen as compared with typical hydrocarbon fuels, but in practical applications, the production of NOx in internal combustion engines is almost inevitable with ammonia fuel, and pure ammonia has a lower laminar combustion rate and heating value than conventional hydrocarbon fuels, and requires a higher energy for ignition, with a narrower flammability limit range, making ammonia combustion more difficult. Meanwhile, because ammonia is toxic, if ammonia is not completely combusted and discharged from the cylinder, it may cause harm to personnel. Therefore, there is a need to modify or redesign conventional combustion systems to enable reliable, safe and clean application of ammonia.
In most of the prior patents, the combustion of ammonia fuel is improved by adding high-reactivity substances, but the combustion temperature is increased and the NOx emission is increased. Patent CN114483299A mentions a system for reducing unburned ammonia emission of an ammonia engine, which utilizes an intelligent charge compression ignition combustion mode to reduce ammonia emission concentration, and utilizes waste heat of engine exhaust to catalytically generate hydrogen from ammonia in exhaust gas, wherein the generated hydrogen is used for improving ammonia fuel combustion, but because the content of ammonia in the exhaust gas is limited and the temperature required by ammonia cracking catalysis is high, sufficient hydrogen cannot be provided to improve combustion, and there is a risk of incomplete ammonia catalysis in the exhaust gas. Patent CN114738140A mentions a zero-carbon engine with ammonia-hydrogen mixed combustion and a control method thereof, which adopts a compression ignition hydrogen gas mode to ignite ammonia, and simultaneously utilizes the high reactivity of hydrogen to promote the combustion reaction in the cylinder, so as to eliminate the ammonia escape phenomenon caused by excessive ammonia mixing amount.

with reference to fig. 1-5, the ammonia diesel dual fuel engine adopting double-loop linkage supercharged EGR of the present invention includes a piston 1, a cylinder jacket 2, an exhaust turbocharger turbine 3, an exhaust passage 4, an exhaust valve 5, an in-cylinder direct injection ammonia injector 6, a high pressure common rail injector 7, a cylinder head 8, an intake valve 9, an intake manifold 10, an intercooler 11, an exhaust turbocharger 12, an exhaust gas filter 13, an independent electrically-driven compressor 14, a high temperature EGR flow regulating valve 15, a wide-flow area EGR cooler 16, and an EGR mixed flow chamber 17. An in-cylinder direct injection ammonia injector 6 and a high-pressure common rail injector 7 are arranged on a cylinder head 8, to which fuel is delivered by an ammonia supply system and a diesel supply system, respectively. The inlet of the two-way charge EGR system is located on the exhaust manifold 4 after the exhaust gas turbocharger turbine 3 and the outlet of the two-way charge EGR system is located on the intake manifold 10 after the intercooler 11.

The high-efficiency combustion method of the dual-fuel engine comprises a pure diesel combustion method and a diesel/ammonia dual-fuel combustion method based on variable-temperature high-pressure EGR, and high efficiency and low emission of the engine under the full-operation working condition are realized by coupling the injection rule of the in-cylinder direct injection ammonia injector and the injection rule of the high-pressure common rail injector with the EGR supply rule.
The pure diesel oil combustion method comprises the following steps: under all working conditions, the high-pressure common rail oil injector injects diesel oil to burn when the piston moves to be close to a compression top dead center, and can be flexibly switched with a diesel oil/ammonia dual-fuel combustion method based on variable-temperature high-pressure EGR according to economy and emission requirements. When the engine is in a starting condition, because the temperature of parts is low, the temperature of the compression end point in a cylinder is low, and the ignition point (527K) of the diesel oil is far lower than that (930K) of the ammonia, the diesel oil is selected to reduce the situations of incomplete combustion or fire.

Under the low-load working condition, diesel oil is used as main fuel, ammonia fuel is used as alternative fuel, and the double-way supercharging EGR system supplies high-temperature EGR. When the engine is in a low-load working condition, because the temperature of the machine part is low, the heat dissipation loss of the engine is large, the compression end point temperature in the cylinder is low, the engine is easy to catch fire, at the moment, the temperature of the engine is increased mainly by high-temperature EGR, the requirements of improving the activity of reactants in the cylinder and avoiding catching fire under the low load are met, and the combustion efficiency is improved.
