"That's right, there is this idea, my idea is to leave the factory with 1200 horsepower, and after a slight modification, it can break through 1500 horsepower," Lin Hongfei nodded, "modestly" to Sigmund. Mia asked, "Mia, what do you think?" ”

The requirements for a civilian engine are very different from those for racing, and as a civilian engine, you can't squeeze out the power like the engines used in a professional F1 car.

For example, the RA168E engine used in the MP4/4 racing car of the Honda-McLaren team in the 1988 season has only a displacement of 1.5 liters, adopts a V-shaped six-cylinder structure with an 80-degree cylinder angle, two IHIRHX-6 turbochargers that can provide a maximum boost value of 2.5bar (the limit value of the F1 competition system at that time), the oil speed is 12300rpm, the maximum limit speed is nearly 30000rpm, and the weight is only 146kg. The ultimate output power can reach an appalling 1400ps or so, and the data is beautiful, right? Except for the fuel consumption of 100 kilometers is a little higher, there seems to be no other big problem, except for one problem: it can only be used for two sessions at most, and it is still playing cylinder bursting to strike at every turn.

No way, almost everything in the design of this engine has reached the limit value, and the throttle is slightly stepped on a little bit to play a strike, if this engine is installed on a civilian supercar, the data is definitely good-looking, but who can stand this kind of temper?

Back to the civilian market, in this era by Japan and those so-called rioters, hurricane groups to blow the mountain of Mazda RX-7FC/FD, Mitsubishi lancerEvolution, Honda S2000, Nissan skyline GTRR32, etc., although the factory power is only 280 horsepower, but it is often modified to six or seven hundred horsepower, especially the use of rotary engine Mazda RX-7FC/FD, it is said that some people modified thousands of horsepower, by countless people as a classic to worship, It is considered to be a symbol of the great potential of Japanese cars to be modified. But they all selectively forgot one thing: how long would the engine last after such a devastating modification that was designed to sacrifice the engine's lifespan?

To be sure, the Mazda RX-7FC/FD with a maximum output of 1000 horsepower after being modified has not been on the track once, but a maximum output of 1100 horsepower is different from the engine that was designed from the factory, which means that even if it is a simple modification, the subsequent need to replace it with a larger air intake flow is repeated, this goods can easily 1500 horsepower, supplemented by other modifications, It is completely possible to break through 2000 horsepower without having too much impact on the service life of the engine...... A 2000 hp supercar engine, this should be considered an artifact, right?

"All I can say is. It's crazy! "Sigmund. Mia smiled wryly.

This is really crazy, because again, there has never been a sports car company in the world that has tried to produce a monster that can reach 1000 horsepower from the factory, and there is only one reason, there is no way to make a good balance between the maximum output of the engine and the durability of the engine. Sigmund. Mia didn't expect this thing to make countless supercar designers lose their hair on the ground. It was so simple for Lin Hongfei to solve it: since the V8, V10, and V12 engines are not good. That's W24!

Although this method is a bit clumsy, it brings a sudden increase in the weight of the sports car, counting the huge engine cooling system, Sigmund. Mia estimates that the car's final curb weight will exceed 1,900 kilograms, which is equivalent to 1.6 Ferrari F40 supercars.

Although there are many problems to be solved in the future, such as a high-strength frame that can withstand huge overloads at high speeds, a high-strength transmission and conventional systems that can withstand such a large amount of power and torque, a high-strength suspension and brake system, and a cooling system to ensure that the engine system works properly...... There are a lot of problems that need to be solved. But in any case, if Lin Hongfei can really solve the problem of the most important engine, then the first supercar in the world with a factory power of more than 1000 horsepower will not be too far away.

Well, at such a high power. Imagine that the top speed can almost exceed 400 kilometers per hour, right? Thinking of this speed, I can't help but feel a little longing.

Her interest rose, "Can I also be involved in this project?" ”

"Absolutely." Lin Hongfei nodded, of course this is not a problem,

"If you really want to do this, then the cylinder walls have to be reinforced, and ......"

With Lin Hongfei's permission, Sigmund. Mia immediately made the transition: from a heavy-duty diesel designer to a supercar designer, and immediately identified the biggest problem with the design, "24 cylinders connected to a crankshaft at the same time, well, this is a 13.2-liter engine, according to your design specifications, the crankshaft of this engine has to withstand at least 1400 Nm of torque...... Can you find a high-strength material that can withstand such a massive torque shock as the heart of this engine: the crankshaft? ”

Professionals are indeed professionals, and they can see the biggest problem with Lin Hongfei's design at a glance: the material of the crankshaft.

For such an engine, the design of the cylinder head is not a problem, the design of the cylinder is not a problem, and even the design of the connecting rod, the design of the cooling system and other aspects are not a problem, which can be further developed on the basis of the existing technology, but the crankshaft ......

Esigmund. Mia's knowledge of the metal materials industry in the Republic of China wanted to find a metal rod of such high strength to be processed into a rod that could withstand at least 1400 N. m torque impact crankshaft, this difficulty is really not ordinary! It has been almost two years since I came to this country, and I have never come into contact with such high-level metal materials.

Of course, if it is a large diesel engine, there is no problem, to achieve such a large torque, even only an in-line six-cylinder heavy-duty diesel engine can do this, with the current metal materials of the republic there is no problem at all, but 24 cylinders...... The machining technology and length of this crankshaft are much more difficult and the strength is much higher than that of the crankshaft of the in-line six-cylinder diesel engine.

"The cylinder block material, my plan is made of thickened forging materials, which has always been able to withstand such a high strength cylinder pressure, as for the manufacturing materials of the crankshaft...... Lin Hongfei blinked his eyes and asked in a low voice, "Mia, what do you think of ultra-high-strength titanium alloy?" ”

"Machining crankshafts with ultra-high-strength titanium alloy rods?" Sigmund. Miaden's eyes widened, she knew very well the weight of this kind of thing to a country, but the more so, the more she was a little suspicious, "This is something that every country will focus on controlling, do you have it?" What about performance? ”

"It is a high-strength substable titanium alloy rod with a tensile strength between 1,100 MPa and β 1,400 MPa at room temperature, which a friend of Mr. Primakov obtained from a certain Russian space department, with a total of less than 5 tons and a asking price of $1 million."

"Then you've made a big bargain." Sigmund. Mia's eyes were filled with envy, she was really envious, this was a high-strength sub-stable titanium alloy rod with a tensile strength between 1100MPa and 1400MPa β room temperature, which was definitely a magic weapon for an engineer and designer who works with metal all day long!

Moreover, this kind of high-strength sub-stable titanium alloy rod with a tensile strength between 1100MPa and 1400MPa at room temperature β has a full 5 tons! It's just under $1 million! This is a good thing that can only be used in the key parts of large aircraft and space vehicles, but the so-called titanium alloys on the market are fundamentally different.

But, "boss, you are going to make engine crankshafts in their entirety from such titanium rods?" Wouldn't it be too wasteful? ”

"I plan to only produce 100 to 200 units of this engine in total, and the maximum will not exceed 400 units, and I don't expect it to make money.

"Is it limited to a maximum of 400 units? That is, only 400 crankshafts are needed at most? "Sigmund. Mia quickly thought about it in her heart, and finally nodded, "That's not too wasteful, but this kind of high-strength thing, do you have processing equipment in your country that can process this material?" ”

"Huh?" Lin Hongfei was dumbfounded, and he suddenly realized that he had forgotten the most important point: the less than 5 tons of titanium alloy rods that Primakov's friend sold to him for $1 million were indeed good things, and they couldn't be better than good things. Mia was right, how do you make this thing?

Anyway, according to Lin Hongfei's knowledge, there is no place in China that can process such rigid strength materials, and there is no such special tool at all.

"Do you have a way?" Lin Hongfei looked at Sigmund cautiously and hopefully. Mia.

"Of course, I also know a lot of friends in Germany, just machining a batch of engine crankshafts, which is not a big problem, but there are conditions," said Sigmund. Mia's face was proud, she raised a finger, and took the opportunity to blackmail her boss, "After the crankshaft is processed, all the remaining scraps must be given to me." ”

Is it just processing leftover titanium alloy scraps? While that's a good thing too, ...... Lin Hongfei gritted his teeth in great distress, "Deal!" ”

The machining of the crankshaft can only be left to Sigmund. Mia, she can't even help herself. (To be continued.) )
