"So much?" ZHANG LAN WAS A LITTLE SURPRISED, IF THE NEWLY DEVELOPED 250-CC ENGINE COULD STILL GUARANTEE 80% OF THE OUTPUT OF THE ENGINE ON THE ALICE-DUCATIDIANA MARK-5 WHILE THE COST WAS DOUBLED, THEN THE ACHIEVEMENTS OF THESE GUYS WOULD BE SIMPLY AMAZING. You know, the output of the 250 cc engine is equivalent to the output of the current 400 cc engine in Japan. Wouldn't this prove that this newly developed 250cc engine will surpass the Japanese 250cc series of engines in terms of performance?

"It's okay, it's all thanks to everyone." Maxim pretended to be modest and nodded, but in fact, pride had been written all over this guy's face, and he almost pointed to his nose to show off to Zhang Lan and the others.

"And what about the 400 to 500 cc engine?" Xiao Chenxi asked.

"This engine was not developed from scratch, but was improved and improved on the company's existing 500-cc four-stroke engine," says Maxim. ”

"It doesn't matter," said Alice, "tell me, how much the engine you've improved is in terms of performance compared to the original?" ”

"Thirty percent!" Maxim was visibly excited, "Just by increasing the top speed of the engine and improving the design of the cooling system, plus the re-optimization of some system components, the overall performance of this 500ml engine has increased by 30% compared to the previous one!" Uh," Maxim was a little embarrassed at this, "Of course, in order to improve the performance of this engine, some important parts inside have been replaced with stronger materials, so the cost has increased by almost 30 percent." ”

"That's right." Zhang Lan replied softly, secretly thinking in his heart: a 30% increase in performance means that this engine is much better than the 400-milliliter engine of any production car on the market now; And the cost has increased by 30 percent, although the problem seems serious. But in fact, it is not very big, because this engine was originally designed on the previous engine, and a large number of original mature technologies were adopted, and the cost was relatively low, even if the cost of this increase of 30% was added. It will not be higher than the current international price of 400 to 500 cc displacement engines, so that this engine is still very advantageous, not to mention that after mass production, the cost should be further reduced.

Thinking about this, Zhang Lan nodded, "Compared with the performance improvement of this engine, the increased cost is still acceptable to the company." ”

Hearing Zhang Lan's statement, Maxim was a little unconvinced - although Zhang Lan's little guy had the final say in the company, he was not the boss after all. This matter still needs to be expressed by the big boss - and then he turned his head to look at Alice, and found that the big boss of the Alice Group was also nodding, and Maxim's heart finally relaxed, and at the same time there was a burst of excitement: this engine is definitely adopted by the company!

For a designer, each engine is equivalent to their own child, when designing this engine, watch it from a line on the paper, into a part, and then in their own hands little by little slowly shaped, until a complete sample appears. The whole process is like watching your own child slowly grow from a baby who has just fallen to the ground, and the joy is beyond words.

If the boss is not satisfied, and with a "click" he shoots the research results that he has worked so hard for a long time, it feels not much better than his own child being lost. Many people will be depressed for a long time, and it will take a long time to calm down. Since the boss says so now, it's really not appropriate!

"There is also this engine with a displacement between 600 and 800 cc," without waiting for Zhang Lan and Xiao Chenxi to ask, Maxim took the initiative to introduce to them, "Now in the world, motorcycles generally choose the 750 cc level in this displacement group." Although there are engines with a displacement of 650 ml or 700 ml or even 800 ml, the most is the level of 750 ml displacement, and the engine of this level can achieve a relatively perfect balance in speed and driving control, which can be regarded as the golden displacement in motorcycles, so we also chose the level of 750 ml displacement. ”

Alice nodded, did not speak, and motioned for Maxim to continue.

"A car of this class," Maxim nodded when he saw Alice's movements, "in terms of its basic structure, it is basically not much different from the structure of a 500ml four-cylinder four-stroke water-cooled engine, which is also a four-cylinder four-stroke structure, but the cooling system of the engine is optimized and the volume of the cylinder is expanded, and the rest are some minor adjustments." Based on this, we considered whether it was possible to increase the cylinder volume on the basis of the 500 cc displacement engine, and then enhance its cooling system to reach the 750 cc level? ”

"The result?" Zhang Lan asked very cooperatively, "What is the final result?" ”

"Of course it turned out to be a success!" Speaking of this, Maxim looked proud, "On the basis of the water-cooled four-cylinder four-stroke engine with a displacement of 500 cc, after we redesigned the volume of the cylinder, optimized the design of the intake valves, and used double overhead camshafts to strengthen the strength of the connecting rods, in this way, a powerful and amazing torque 750 cc engine successfully appeared in our hands!" ”

"How does his performance compare to the current GM 750 cc? How much does it cost? Zhang Lan asked eagerly, this is what he is most concerned about, if the performance is not improved much, then it is not of much significance, it is completely a piece of chicken ribs, tasteless to eat, and it is a pity to abandon it; Conversely, if the cost is too high, even if the performance hits the original design goal, it doesn't make much sense: everyone else's is cheaper than yours, so why buy yours?

This kind of motorcycle is mainly for overseas people, and it doesn't matter if you are from China or Japan, the money in your pocket is the most important thing.

"In terms of performance, the power is basically the same as the popular 750cc engine today, because we use EFI technology, so the performance can still be done a little bit," Maxim gestured with his hand, pinching the size of his fingers, "It can probably make 3% to 5% of the appearance, but our product has a great advantage, that is, the torque is much higher than those Japanese 750cc engines, so under the same displacement, the same power, The advantages of our engine in terms of acceleration from the start are even more obvious. ”

Zhang Lan rolled her eyes when she heard this, if it wasn't a racing car, the higher power would really be meaningless, but if it was a racing car, it would be different, who didn't have the heart to get more torque output in order to occupy a pretty good advantage at the start?

"As for the cost, it's much more controlled!" Speaking of the cost, Maxim became excited, looking at the excitement of this guy, it was obvious that this was what he was most proud of, "The cost is about 35% lower than the cost of similar international products!" ”

Scare! So much! Zhang Lan's eyes widened in disbelief: Wouldn't it?

How can it be? Not only Zhang Lan, but even Xiao Chenxi and Alice widened their eyes, almost unable to believe that what Maxim said was the truth.

"You know, the labor cost in China is much lower than that of developed countries like the United States and Japan!" Maxim revealed the secret in one word, "That's why it's so low." To tell the truth, if this engine is produced in the United States or Japan, it will cost about 10% to 12% more than the same displacement engine they produce! ”

I see! Zhang Lan, Xiao Chenxi and Alice suddenly realized: how did they forget this key link, and what is the labor cost of their company? What is the labor cost of these developed countries such as Japan and the United States? There is no comparison between the two!

"And what about the last set of engines?" Alice asked eagerly, more concerned about this monster with an exhaust of more than 1000 ml, "How is the current development progress?" ”

"This engine has been completed on paper, after our calculations are no problem at all, the required parts and materials have been in place, but now there is no sample, the engine parts are being made, that is, I told you at the beginning, these two days can be completed all the engine parts production, the rest is to carry out the final engine actual test." Maxim shrugged his shoulders with some regret, "But sometimes, after all, the actual results are still a little different from the results calculated by myself, so there is no way to tell you." ”

"Oh," Xiao Chenxi asked, "can you give us a general introduction?" It's about the data that you're calculating right now. ”

"If that's the case," Maxim pushed his glasses, the excitement on his face could not be suppressed anyway, "as far as I know, it seems that among the current production cars, I mean motorcycles, cars that have not yet reached such a huge displacement, and this engine is the one that we have taken the longest time and the most painstaking effort." The displacement is 1200 cc, more precisely 1198.2 cc, the water-cooled four-stroke parallel four-cylinder EFI engine, the instantaneous maximum speed of the engine can reach 19,000 rpm, the maximum speed of safe sustained speed can reach 16,000 rpm, and the maximum output power has reached an unprecedented 202 British horsepower, which is the first time that the engine power of the engine exceeds 200 horsepower among the engines of the mass-produced supermotorcycle sports car!
