Automotive Black Technology Chapter 943: : Poseidon H series engine is released!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
Han Yi set the direction and ideas with Li Fanyu, and the rest will be easy to handle.
For those who have such a heaven-defying bug as design specialization, if you have a beginning, the rest can be continued.
According to Mr. Han's guidance, since there is no foundation, it is better to give it a try and move towards the highest technology currently. That is the legendary dual-fuel ship engine.
Li Fanyu is not unfamiliar with the concept of dual-fuel engines. In fact, they are engines that use diesel as the ignition fuel and combustible gas as the main fuel.
The diesel-natural gas dual-fuel engine currently used in research and development is more commonly used.
Compared with petroleum, liquefied natural gas has the characteristics of abundant reserves, easy use and clean emissions. Basically free of harmful substances such as sulfides and tiny particles, it can effectively reduce 90% of nitrogen oxides and 25% of carbon dioxide emissions, making it the most ideal choice for alternative energy sources in the future.
More importantly, gas is cheaper than marine diesel. When working for a long time, it is more friendly to the environment and more economical.
But in this dual fuel including natural gas and marine diesel, Mr. Han combined his own views and gave two oil branches, namely conventional marine diesel fuel and heavy oil fuel.
During the oil process, the lighter parts are separated first. Therefore, during the processing of crude oil, gasoline, kerosene, and diesel will be produced in sequence. These three lighter oils, these three oils with relatively high combustion properties are collectively called "fuel".
The heavier residue left at the end is called heavy oil, which is also the legendary scrap tailings.
The burning performance of this kind of thing is not very good, but it can still burn. Therefore, it is commonly used as fuel for boilers, heating furnaces, metallurgical furnaces and other industrial furnaces.
The reason why this is specially drawn is that it is actually similar to using natural gas as fuel, and it also enhances the economy of the engine. In order to meet the economic performance of the reclamation vessel's long-term operation and reduce the difficulty of supply.
So according to Mr. Han's guidance, the engine designed by Li Fanyu and Liu Qing can actually use three types of fuel.
According to Liu Qing's idea, Zhengxin wanted to make achievements in the field of communication engines. One or two separate products would never be able to form competitiveness and product advantages.
So it is better to take advantage of this opportunity to spread the four engines required by the Yishu project as the core, explore up and down, and make a series of products.
According to the requirements of the First Dredging Group, because reclamation operations need to be carried out in the open sea area, the power of the main propulsion engine must be large.
To meet navigation requirements, the power of the main propulsion engine should not be less than 6000KW.
The other two engines mainly provide power for the hydraulic pump and cutter suction system. In order to ensure operating efficiency, the power must not be less than 3000KW.
The other engine provides power for the entire ship's lighting, communications, firefighting, fresh water purification and other functions. It is used as a constant-speed generator set with a power of no less than 1500KW.
Originally, according to Li Fanyu's intention, it was easier first and then more difficult. The Shanshen I-type diesel engine that best met the technical requirements of the First Dredging Group was magically modified. The two 3000KW power working engines were first solved.
However, after being guided by Mr. Han and fully considering Liu Qing’s serialization suggestions, Li Fanyu decided to overturn the previous plan and start from scratch.
Although this requires a lot of energy, it will lay a very good foundation for Zhengxin in the field of ship power in the future.
It’s just that the workload of such research and development is too great.
Even with the help of design experts and dozens of outstanding engineers from the special equipment R&D department, Li Fanyu and Liu Qing still stuck themselves in the studio for a whole week before completing the three cylinder series of 20.30.46 , L6.8, V12.16.18, five models each, dual-fuel medium-speed marine engines covering the entire needs of maritime ships!
After making considerable optimization improvements, it was officially put into testing.
In order to combine the power naming method of the previous special equipment R&D center, Li Fanyu named the new series of engines after Poseidon.
In order to thank Academician Han Yiming for his inspiration for the series of engines, the first generation series of engines was named Poseidon H.
H, naturally represents Academician Han Yiming.
Series engines can use gas, marine diesel or heavy oil as fuel. And it can switch smoothly between various fuels during operation.
The independent liquid fuel system designed by Liu Qing and optimized by Li Fanyu can ensure that the output power remains unchanged during the switch from marine diesel to heavy fuel oil.
In gas mode, compared with fuel mode, the engine's economic efficiency is increased by 35%.
Carbon monoxide emissions can be reduced by about 75%, carbon dioxide emissions can be reduced by about 20%, nitrogen oxide emissions can be reduced by 80%, and 100% reduction of sulfide emissions can be achieved!
Such emission standards fully meet the Tier III standards of the International Maritime Organization.
As long as this standard is met, Poseidon H series dual-fuel engines can theoretically be applied to gas ships, offshore supply ships, chemical tankers, icebreakers and other ocean-going ships!
And even more exciting is.
After a series of intense tests, Poseidon H series engines have obtained parameters that are enough to make any practitioner in the Chinese shipbuilding industry scream!
Poseidon H20, a series of engines suitable for constant-speed generator sets or smaller variable-speed machines, is divided into three models based on the number and layout of cylinders.
The maximum continuous power of Poseidon H206L is 1110KW, 8L is 1520KW, and 10L can reach 1850KW!
This kind of performance, if used to generate electricity, can completely satisfy a village with 70 to 100 households, each with modern household appliances!
It is simply a small power station.
The Poseidon H34 series, which meets the needs of ship propulsion main engines and generator sets, is divided into four models.
The maximum continuous power of 6L is as high as 3000KW. As the most basic model of this series, its performance has far exceeded the Shanshen I type that Li Fanyu designed randomly before!
The 8L, 10L, and 12V have reached an astonishing 4000, 5000, and 6000KW!
Among them, the high-end engine of this series, namely Poseidon H3412V, with a power performance of 6000KW, is fully capable of being used as the main propulsion engine of any 10,000-ton giant ship.
This engine can also meet the main power requirements of the First Dredging Group for the reclamation ship.
But it is obvious that with the help of an explosion of inspiration and design expertise, Li Fanyu did not stop there.
So, in Zhengxin’s testing laboratory, engineers saw the Big Mac among engines, the king among Big Macs—the Poseidon H46 series that can knock down a crowd just from its appearance!
Different from the previous engines, there are also engine cylinder numbers of 6 and 8. This series of engines starts with 10 cylinders!
The lowest performance model is the Poseidon H46L10, the only L layout product in this series of engines, with a power of over 10,000 – reaching an astonishing 10,500KW!
The three higher-level engines of 12V, 14V and 16V have reached super powers of 14500KW, 16800KW and 18800KW respectively!
Although this series of engines has not been tested for shipboard use, judging from the parameters alone, it has already reached international leading standards!
As soon as the test here ended, Li Fanyu immediately informed Tongyang Dredging Group of the news.
Faced with Zhengxin’s research and development speed of more than two weeks, Liu Shengyuan, the chief engineer of Tongyang Dredging in charge of this project, had deep doubts.
So, after some discussions, Liu Shengyuan personally invited ship engine experts from Zichai, Yuchai and Weichai to form an inspection team.
The second week after Yu Zhengxin’s first successful test on the Poseidon H series, he came to Tiancheng.
