Chapter 2808

"What a good thing! The power of this diesel engine should be much greater than the steam engine installed on the Majesty-class top, right?" Chen Yixin kept staring at the waves stirred up by the propeller on the sea, and asked Bai Kesi with envy.

Bai Kesi nodded and said: "The design power is nearly half greater than the Nanhai C-type steam engine used in the Majestic class. This ship is equipped with two units, which can easily increase the speed to more than fifteen knots."

Chen Yixin asked: "Has this thing been mass-produced? When can you arrange dozens of units for me?"

"Dozens of units? Even arranging just a few units is difficult!" Bai Kesi smiled bitterly: "At present, it can only be said that it is finalized, but it is still far from mass production. The processing technology is imperfect, the production cycle is long, the service life is short, and the operation

The reliability rate is not enough, maintenance and repairs are inconvenient, and there are still a lot of areas that need improvement. Moreover, this thing burns diesel, which means it relies much more on supply points than a steam power system, and it will be difficult to popularize it in a short time.

."

Chen Yixin said with a smile: "Otherwise, the Ministry of Industry will provide several diesel engines and installation plans, and I will pay to build a few new ships, which will be used as experiments for the new engines. At that time, the Ministry of Industry can also collect usage data and use it.

to improve the process.”

Bai Kesi glared and said: "You are really good at calculating! This thing is not so easy to use in the north, especially in winter, it will be very difficult to start."

Chen Yixin said: "In this case, it is even more necessary to increase experiments in the northern region. This thing has been manufactured for so many years, can't it just be used in the south?"

Diesel engines are actually nothing new to Haihan. More than ten years ago, Yu Feng of the First Machinery Factory had already led a group of people to build a prototype, which was even made a headline in the Times at the time.

Hot discussion.

In the following years, the Ministry of Industry built on this basis and successively manufactured diesel generators, diesel trucks, diesel tractors and other equipment, and naturally some of them were also used on ships.

But at the same time, the manufacturing precision and maintenance difficulty of diesel engine parts far exceed that of steam engines. In addition, special fuel is required, so the manufacturing and use costs have always been high, also far exceeding that of steam engines.

engine, which greatly increases the difficulty of promoting diesel engines in various fields.

Although diesel engines have been manufactured, they have not been widely used in the past ten years or so. Only some official organizations can ignore the cost to use such equipment. This in turn has led to the research and development expenses of related projects.

Limited, the upgrade in manufacturing technology has also been slow to develop.

The main user of marine engines is, of course, the Navy. However, after weighing the overall cost and reliability of use, the Ministry of National Defense does not want to replace large areas of diesel engines on the new ships it builds. Instead, it prefers to use mature technologies and more reliable maintenance.

Convenient steam power system. Until the production and use costs of diesel engines drop significantly, the steam power system will still be the navy's first choice.

It is even less likely that civilian ships will use this high-cost power system. For merchants, most of the goods transported by sea do not have strong timeliness requirements. Using engines can greatly increase the benefits of speed.

, it is likely that it will not be able to make up for the increased operating costs.

At present, only a few powerful shipping companies have begun to try to install steam power systems on newly built large sailing ships to run some relatively fixed long-distance routes with stable cargo volume.

Bai Kesi believed that this was because the northern region was too remote. Before that, Chen Yixin had not specially sent anyone to participate in the sea trials organized by the Ministry of National Defense. He did not know much about marine diesel engines, so he thought it was a good thing.

.

However, he would soon discover that Chen Yixin's interest in diesel engines was not just for use in naval ships.

With the blessing of advanced power equipment, the ship left behind the other two escorting warships at extremely fast speeds, and sailed from Zhifu Port to Penglai Port outside Dengzhou City in just half a day.

The two diesel engines on the ship performed in good condition during this period without any malfunctions. This greatly increased Chen Yixin's confidence in them and once again mentioned the Northern Fleet's proposal to introduce diesel engines to Baikes.

The Penglai Port currently used by Dengzhou City is actually the Shuicheng Military Port where the Dengzhou Navy was stationed in the past. However, the establishment of the Dengzhou Navy existed in name only during the Denglai Rebellion. After Haihan stationed in Fushan County, it changed

We won't let it have another chance to resurrect.

After the Qing army invaded Shandong in 1639, Haihan took advantage of the situation and began to openly take over the Dengzhou area from the Ming Dynasty. Although the Ming Dynasty still maintained its rule in a few prefectures and counties such as Dengzhou City, it actually changed the situation of Haihan from cannibalization.

There is no way to deal with the expansion measures for annexation, and we can only watch the situation worsen step by step.

By around 1645, the Northern Region no longer recognized the legitimacy of the government agencies established by the Ming Dynasty in Dengzhou, and required agencies headed by the Dengzhou government office to hand over household registration and field records and other information to Haihan, and withdraw from the Dengzhou area within a time limit.

Otherwise, force will be used to achieve the goal.

After procrastinating intermittently for another three years, the Ming Dynasty no longer had an organized armed force in this area. There were only a small number of armed servants affiliated with local officials. They were not a single enemy of the Haihan army at all. The Ming Dynasty realized that it could not recapture Shandong.

In the area that had been de facto occupied by Haihan, the two sides finally reached a peace agreement through lengthy negotiations.

The Ming Dynasty transferred the governance of Denglai and Denglai states to Haihan in the form of "trusteeship" and evacuated all official personnel affiliated with the Ming Dynasty. At this point, Haihan almost seized control of the entire Jiaodong Peninsula without any bloodshed.

At this time, the administrative seat of the Northern Region has been set in Jinzhou. The core area in Shandong is the emerging seaport city centered on Majiazhuang and Zhifu Port. Chen Yixin is not interested in revitalizing Dengzhou, so this area is planned.

After returning to Han Dynasty, there were no major changes in appearance, and it almost maintained its original appearance.

Everyone landed from Shuicheng, passed through the Zhenyang Gate on the south side, and saw the adjacent Dengzhou City.

There is also a moat between Shuicheng and Dengzhou City. As Chen Yixin walked, he introduced to Bai Kesi and Bai Letong: "In the Denglai Rebellion, the rebels led by Geng Zhongming and Kong Youde fought out of Dengzhou from here, holding them hostage.

The navy fled to Liaodong and surrendered to Hou Jin Dynasty. After this battle, Shandong's vitality was severely damaged and was no longer able to support the Ming army's anti-Jin war in the Liaodong Peninsula. Look at the city walls here, the damage and craters on them are from the fierce fighting at that time

The traces left behind.”

Bai Letong walked closer, and sure enough, the ruins left by the war could be seen everywhere on the city wall, with large craters as large as a washbasin. Thinking back to the fierce war situation back then, Bai Letong also truly felt the weight of history that cannot be expressed in words.
