You don't have to be so stunned, the opposing piston diesel engine may be higher than the traditional diesel engine in unit power as you said, but how much space does the corresponding space need?

That's not all, the mechanism of your opposing piston diesel engine is also very complicated, and it is bound to be difficult to maintain, which must be a big burden for the transmission of ocean-going missions.

And the measurement system you use is the imperial system, and our measurement system is quite different, if you want to introduce our investment in the measurement system is not a small amount, based on the above, if you also say that this diesel engine is the culmination of British technology...... Hehe......"

Fu Guangqi's words came to an abrupt end as he spoke, only replaced by "hehe", as for his eyes, it was even more helpless with indescribable contempt, as if to say, your brother is using this to fool me?

Avery Lison wanted to refute, but he opened his mouth, but he couldn't say a word, there was no way that Fu Guangqi was to the point in every word, so he couldn't even find the space to refute, so he blushed and was stunned for a long time, and finally put away the drawings and explanatory materials indiscriminately, and went out with a gloomy face.

Fu Guangqi didn't care about Avelison's attitude at all, he took the tea on the side and moistened his throat, and then softly ordered the staff on the side: "Next!"

……

Corymenson walked into the door happily, the face of Averlison when he went out just now was even more gloomy than the rainy day in London, Corymensson looked at it squarely, and he didn't need to ask to know that the British were hit on the head again this time and broke the blood, but who can blame for this?

It's not that the British can't find it themselves, the technology is already not good, and you have to pretend to be a big-tailed wolf, if you don't get pressed to the ground and rub, who else can you press.

So just wait for yourself to take down the Chinese, and then happily swallow your British diesel engine company is the king.

With this thought, Cory Mensong called Fu Guangqi enthusiastic after entering the door, fortunately he is a pure man, if he is a woman, what method will Bao Qi use to express his enthusiasm.

But around that, Fu Guangqi was also a little anxious by Cory Mensson, but fortunately, Fu Guangqi's experience over the years is quite rich, and he has seen Cory Mensson's tricks quite thoroughly.

Corymenson looked at it, yo, the old driver, it seems that it is not possible to be a little fierce, so he picked up the briefcase he was carrying, and took out more than a dozen detailed structural drawings.

Then pointed to a cylinder above the four small round holes and said confidently: "This is our company's latest research and development of four exhaust valve mechanism, the traditional diesel engine has only one exhaust valve per cylinder, the efficiency of exhaust is low, and it affects the power of the diesel engine, our four-valve structure is optimized for the inherent defects of a single valve, the test results also confirm that our idea is right, here is the comparative test data of the four-valve structure and the single-valve structure." ”

Saying that, Cory Menson handed a booklet with a delicate cover to Fu Guangqi, Fu Guangqi took a look at the booklet, and his eyes couldn't help but narrow, if the data above is true, the four-valve structure does have considerable advantages.

So he picked up a few drawings and looked at the details of the four-valve structure, Fu Guangqi, who had put down the drawings for a long time, shook his head regretfully.

Cory Mensong, who originally thought that he was ten out of ten, couldn't help but chuckle in his heart when he saw Fu Guangqi shaking his head, but before he could ask how, Fu Guangqi had already spoken: "The four-valve structure is very unique, but Mr. Cory Mensong, I don't know if you have noticed that your structure is a very lame design from the perspective of use."

You must know that one valve needs two sets of springs, and four square valves are eight sets of springs, and the skin damage rate of multiple springs that have been in working condition is much higher than that of two sets of more robust springs in a single valve, so it virtually increases the burden of maintenance.

In addition, there are dead spots in the middle of your four-valve structure, and the sweep will not be very clean, so unfortunately Mr. Corymensson, you should find another partner!"

This time, Fu Guangqi's eyes were not meaningful, and they were indeed all regrets.

But Cory Menson sat there dumbfounded, the whole person was a little confused, he did not expect that the Chinese could directly attack the defects of their company's marine diesel engines, which made him unable to even say words of defense in disbelief.

In the end, Corymensson still went out, but with the support of the Chinese staff, it also caused a lot of sensation among the representatives of other manufacturers in the lounge.

After that, Fu Guangqi received several European manufacturers, all of whom pointed out the shortcomings of these manufacturers' diesel engines, so that these manufacturers came one by one with interest and returned disappointed, until the German MAN CEO Ellongberg entered the door, Fu Guangqi met a real opponent.

Because the marine diesel engine provided by Elnberg has almost reached the level of perfection, anyone who looks at it must be dazzled, and Ellenberg is also very confident, from entering the door to Fu Guangqi reviewing the drawings and technical data, he just said some polite words, not even a basic introduction, because he believes that as long as Fu Guangqi is professional enough, he cannot refuse the perfect quality of their MAN company.

"Uh...... Mr. Elonberg, I've taken a look at your technical data, so I'd like to ask, do your diesel engines use cross-flow sweeping?"

"That's right!"

"Oh, I'm sorry, your engines aren't as efficient as we want. ”

"Why?" Ellenberg, who was still full of confidence a second ago, heard this sentence, and immediately became uneasy.

"It's very simple, your kind of fresh air enters through one side of the window, and the exhaust gas is discharged from the other side of the window hole opposite the cylinder, which is not as fast as the return sweep and the DC sweep, don't believe you look at these formulas...... To put it bluntly, it's a question of efficiency. ”

While speaking, Fu Guangqi wrote down three mathematical formulas on a piece of paper and handed them to Ellenberg, who looked at them fixedly, then sighed, and then said nothing, put away his things and left without looking back.

Looking at the back of Elonberg's departure, Fu Guangqi did not have the joy of victory, but leaned back in his chair with a lucky face, and waited for Elonberg to close the door before exhaling with relief: "I'll be here first today." ”

After speaking, he shouted to the side of the room: "Quick, take it out, today's things are very important, while I am in good shape now, hurry up and write it down." ”

Before the words fell, the inconspicuous door of the room opened with a hula, Meng Jianye and the others pushed out a large drawing tablet, recording paper and other things, Fu Guangqi did not speak, took off the suit on his body, rolled up the sleeves of his shirt, and picked up the drawing pen to draw the structural sketch of the diesel engine provided by Ellenberg just now......
