Stay Eugene. After Rudolph left, August asked Tu Qianjun in confusion: "General, the patent period for diesel engines has long expired. Even now, our German MAN Group has been using this diesel engine in automobiles as early as 1924, and the application of ships has also appeared. Why would you even want to buy these notes and prototypes?! ”

Tu Qianjun and this one is called Eugene. Rudolph bought it from his father, the German engineer Rudolph. Diesel wrote those research notes, and also purchased several diesel prototypes.

August was not wrong in saying that Diesel's patent protection for diesel engines was terminated in 1912. The first truck with a MAN diesel engine was shown at the Berlin Motor Show in 1924, when the Bavarian Post Office purchased a large number of these trucks.

Diesel engines have also been widely used in ships and trains. However, due to the low power-efficiency ratio of diesel engines, this engine has not attracted much attention. Even in 1917, the United States had the first real diesel-powered locomotive, but it was not used in the field of railroads.

Therefore, Tu Qianjun's emphasis on diesel engines made August quite puzzled. Facing Auguste's question, Tu Qianjun leaned over with a faint smile and replied.

"Auguste, my friend! I want you to know that I don't just need a diesel engine, I need more than just a diesel engine, I need to let the students at Northeastern University in Manchuria know how to design this engine......"

In the end, I want a complete improvement! Junzi added a sentence in his heart.

Someone once said that if I were a tank commander in World War II, I would have to fight the enemy alone! There is no doubt that I will choose the invincible King Tiger, and if I am a tank battalion commander going to the battlefield, I will choose the Leopard tank that is both offensive and defensive, and agile and maneuverable.

However, if I command an army group, I want to lead an armored group to break through the enemy's defense line and rush for thousands of miles! So, I'm going to choose the most coquettish tank of World War II - the T-34!

The reason why the T-34 is coquettish enough is because it was the first tank car to have a fuel tank hooked out. And the reason why it dared to plug out the fuel tank was because it used a gasoline engine that was not the mainstream at the time. It uses the diesel engine, which is the mainstream tank engine of later generations!

Diesel has a lower ignition point at atmospheric pressure than gasoline and consumes less than gasoline! It is only susceptible to combustion under the specific high temperature and high pressure of a diesel engine. Yes, the T-34 dared to hang its own external fuel tank directly on the hull!

If you had replaced the Sherman M4 at the time. Or maybe it's a leopard pose, you don't dare! Both the Sherman and the Leopard are gasoline engines, not to mention the plug-in, that is, in peacetime combat, spontaneous combustion will occur from time to time, or be hit by enemy tanks, and the rear will ignite the tank due to the low ignition point of gasoline when the armor has not been penetrated!

Therefore, only the T-34 of the diesel unit dared to put its own external fuel tank on the tank so coquettishly.

And the benefit of this approach to the T-34 is that it increases its strategic itinerary! During World War II, the Soviet Army's 5th Guards Tank Division once created a three-day run of 400 kilometers. More than 460 of the more than 500 tanks arrived at the miracle of emergency plugging.

While there are many reasons for such a miracle, one thing is undeniable: the role of the diesel engine used in the T-34 is the most important! If there is no external fuel tank and a fuel-efficient diesel engine, then the T-34 will run out of fuel after running at most 200 kilometers like Sherman.

And thanks to the diesel engine with an external fuel tank and fuel economy, the T-34 could achieve the miracle of 500 kilometers of running distance that all tanks at that time could not reach! This point completely exploded the 120 kilometers of the Tiger and the 170 kilometers of the subsequent King Tiger full fuel trip.

It's just that diesel engines are not being taken seriously now. And its coquettish rise will come after the coquettish performance of the T-34.

"My motherland lacks a lot of things, but what is most lacking is talent!" Tu Qianjun smiled and whispered to Auguste: "These notes and prototypes. It can provide students with a convenient ...... to understand the mechanical structure of diesel engines."

After completing this transaction, Tu Qianjun did not continue to stay in Germany. This time there is almost everything that needs to be done in Germany, and various agreements have been signed. The most important diesel engine purchase has been completed, and it is time to leave.

At this time, Tu Qianjun received an invitation from England, and the nobles of the English Channel finally couldn't sit still! Boatloads of machinery and a large number of workers went to Manchuria, but the tiger showed no sign of coming to England.

Therefore, at the suggestion of British Prime Minister MacDonald, the British ambassador to Germany invited Tu Qianjun to visit Britain. Tu Qianjun, who got the news, couldn't help but laugh dumbly, he really didn't think about going to the UK for a visit.

Although Britain now seems to be strong. But in fact, everyone knows that the current Britain is nothing more than a foreign power. They can hardly interfere in international affairs, and the inability of 918 has caused them to lose their international prestige.

Originally, MacDonald planned to wait for Tu Qianjun to send a request for a visit, but Tu Qianjun, who arrived in Germany, seemed to be addicted to playing! All this time ignores the UK. This made the original plan to take advantage of Tu Qianjun's visit to the UK to reach more agreements and create more positions.

At first, Tu Qianjun was assassinated, and MacDonald felt understandable. Then Tu Qianjun visited Germany, and it seemed that he was leaving, and MacDonald began to be anxious.

Tu Qianjun thought about it and agreed that he would go to the United Kingdom for a visit. Tu Qianjun did not plan to stay in Britain for long, and Britain was the last stop of his visit to Europe. As for France...... This country that played soy sauce more than soy sauce during World War II was directly ignored by Tu Qianjun.

The proud Gallic rooster also did not extend an invitation to Tu Qianjun, who had just been elected president of France. Lebrun didn't care if Tu Qianjun came to visit. Compared to the sensitive British and the Americans, who saw the opportunity, the Gallic rooster felt that he was doing well now.

After agreeing to the British ambassador to Germany, Tu Qianjun began to pack his bags that night. In two days, we will rush to England. Just as Tu Qianjun was packing his bags, Federica quietly came to his room.

"Boom! Boom! Dong ......" Tu Qianjun, who was packing his bags, replied without replying: "Please come in!" ”

Whether it was in the past or now, Tu Qianjun did not have the habit of letting others pack up. He always packed up his travels, and some special points such as souvenirs given to him by some nobles would be handed over to Chandinand for safekeeping.

Federica gently opened the door and walked in, Tu Qianjun turned around and saw that it was Federica and said with a smile: "Federika, why are you free to come?!" Didn't you say you were going to the Netherlands to visit your grandfather?! ”

Federica was silent for a moment. He whispered to Tu Qianjun: "General, I heard that you have decided to go to the United Kingdom?!" Why didn't you notify me?! ”

In fact, Federica didn't go to the Netherlands at all, this was just a way for the old Prince of Hanover to prevent Federica from continuing to contact Tu Qianjun. However, this manor originally belonged to the Hannover family, and the servants naturally would not stop her. And Chandinand and they would not stop the girl, and the fools could see that the princess was interested in their commander-in-chief.

Tu Qianjun listened to Federika's words and was silent for a while, he was not a fool! The two lives are human, and they are both sixty or seventy years old, how can it be that Shang Dinan and the ideas they have all seen through can't be seen through?!

"Federica, listen to me." Tu Qianjun was silent for a while, and then said in a deep voice to Federika: "I know what you think. Honestly, I thank you so much! But I don't think we're the right fit......"

Federica's face turned pale when she heard Tu Qianjun's fierceness, and she looked at Tu Qianjun with disbelief in her eyes!

And Tu Qianjun looked at Federica and said in a deep voice: "This is not the reason for any identity or status. The most important thing in my opinion is that you don't know me well enough. I don't know enough about my country, my people, my habits, and my history. ”

Federica's face softened a little, and then he hurriedly said to Tu Qianjun: "No! General, I'm sure none of this is a problem! These can be overcome! As long as you like me and love me, then we can overcome all of this, right?! ”

Tu Qianjun smiled, stood up, touched Federika's head and whispered, "Federika, I want you to know." A marriage is not just a matter of two people, in fact, the union of marriage involves the background, family, cultural education, and living habits of two people...... and so on. ”

Saying that, Tu Qianjun didn't wait for Federica to answer before he said to himself: "The cause of love is mostly because of passion, but passion always can't last. You've only known me for a month, except that you know I'm a soldier and I'm a soldier. Do you know anything else about me?! ”

Federika was silent when she heard this, and Tu Qianjun continued to whisper to Federika: "Marriage is a promise, not a child's play. It's not a passion, either. You've only learned one aspect of me now, but not all of me. This kind of love is not real......"

"No!! My love for you is real, you don't have to doubt it! This is also undoubtable! Federica stared at Tu Qianjun with big watery blue eyes and said loudly! There was indignation in those eyes!

Seeing Federica like this, Tu Qianjun laughed dumbly! Turning to Federica, he said, "But we still have differences, don't we?!" These are objectively existing facts, facts that we all have to admit. ”
