Riding a Kawasaki H2 to chase the high-speed rail, the school beauty was moved to tears

Straight line or curve? After thinking for a long time, Qin Chuan did not give an answer.

To be honest, he didn't know either.

“Now that we’ve talked about supercharging, let’s talk about the differences between naturally aspirated engines.”

"All large-displacement engines generally have four cylinders, commonly known as four cylinders, also called four-cylinder engines. Whether a car is fast in straight lines or corners depends on the layout of these four cylinders."

What is the purpose of the cylinder? It compresses the combustion air to produce energy, which increases the power of the engine, such as v8 and v12. The numbers behind refer to the cylinder block, 8 cylinders, 12 cylinders.

Theoretically, the more cylinders, the greater the horsepower, but this is theoretically possible for cars, but not for motorcycles.

The four cylinders of heavy-duty locomotives are considered to be the most balanced.

As for the v in front of v8, it refers to the cylinder layout. The four-cylinder layout is divided into in-line four-cylinder and V-shaped four-cylinder.

The inline four-cylinder is easy to understand. The four cylinders are placed together, one next to the other to form a row, also called a parallel four-cylinder.

The V-shaped four-cylinder is separated, with two cylinders facing forward and two cylinders facing rear, divided into two groups.

The V-shaped four-cylinder is fast in a straight line, and the inline four-cylinder is fast in corners. This is the difference between the two.

As for how to distinguish which car is V or inline, it is very simple. If the car has a v in the name, the engine has a V-shaped layout. Ducati v4, Aprilia rsv4, v is the cylinder layout, and 4 refers to the number of cylinders. .

Of the seven cars in front of me, except for these two, all the others are inline four-cylinders.

Ducati V4 is a V-shaped four-cylinder, which is why it is baked.

All the big rows are hot. Why are they hot? It’s because the cylinder generates heat due to work, but it’s the knees that are hot.

When the engine is installed on the car, the four heated cylinders of the inline four-cylinder are exactly at the position of a person's knees when riding.

But Ducati is different. Ducati has two cylinders on the knees, and the other two are directly under the seat cushion. It is difficult not to get hot.

Ducati is proud of its 90-degree V-shaped four-cylinder. The two front and rear cylinders are perpendicular to each other. The verticality is indeed vertical, but one set of cylinders points to the knees, and the other points to...

"If it were me, I would recommend you choose a car with an inline four-cylinder engine. It is stable in corners and less likely to crash."

After talking about the differences, Xu Hong took the initiative to recommend Qin Chuan.

The inline four-cylinder is the engine layout chosen by most domestic drivers. Although it is not good in straight lines, it has a higher upper limit on curves. The throttle is smoother than the V-shaped one, and it is easier to overtake in curves.

As the saying goes, speed is really fast when you go fast in the curves. Who doesn't know how to drive faster in a straight line?

As a professional driver, if you want to go further, you must specialize in a layout when choosing a large-displacement sports car, otherwise you will become less skilled in the later stages.

Looking at Xu Hong's eyes, Qin Chuan hesitated and whispered.

"Uncle, does a V-shaped four-cylinder curve definitely not work?"

To be honest, after listening to these two, Qin Chuan was more interested in the V-shaped four-cylinder. He is different from other drivers. He has the talent given by the system. Qin Chuan obviously feels that his stability in corners is better than others. .

It stands to reason that in this case, the inline four-cylinder should be chosen to strengthen the corners. The combination of powerful forces is also very good and has a high degree of fit. But that is not what Qin Chuan thinks. What he thinks is that the two complement each other, which is more balanced.

It's fast in a straight line and not weak in corners.

Besides, the feeling of blowing others up in a straight line sounds great.

"Little guy, I know what you are thinking, you want to be more balanced, but the V-shaped four-cylinder throttle is not as smooth as the inline, the crash rate is high, and the chance of injury is also greater. Are you sure you can bear it?"

After hearing Qin Chuan's words, Xu Hong said, "I don't know why. Xu Hong seemed to have known that Qin Chuan would choose V-shaped. It was no surprise."

"Uncle, so the V shape still has advantages."

Qin Chuan caught the blind spot.

"For you, it is true that the V-shape has more advantages than the straight one."

Frankly speaking, there is not much difference between the two. The V-shaped four-cylinder layout is not good at corners, but it does not mean that the V-shaped layout is really weak on the track. On the contrary, the V-shaped layout is very strong, not inferior to the inline at all. .

Nowadays, almost every track has a big straight line, and there is a chance to regain the position if the corner is super straight.

Although the oil will be given when driving in a straight line, if the car is not good enough, no matter how much oil is given, it will never be enough.

From a strength perspective, both have their own merits.

But the V-shaped four-cylinder is violent and has a high crash rate. Crashing means spending money, hurting people, and not being able to complete the race.

Therefore, all things considered, the inline four-cylinder is better and suitable for most ordinary people.

So Xu Hong would recommend this, after all, safety is the first priority.

As for why Xu Hong said that Qin Chuan chose V-shaped racing better, firstly, as Qin Chuan thought, his riding style complemented V-shaped racing, and he had stronger corners than fellow V-shaped racing riders, which was an advantage.

The original balance will be broken here in Qinchuan.

Secondly, every track has straight lines, but the proportion of straight lines and curves in each track is ultimately different. Some tracks have short straight lines and many curves, so straight lines are dominant, and the opposite is also true.

Qinchuan chose the V-type to have better adaptability to the track. If he wanted to go far, he couldn't just stay on the track in Magic City.

Safety and strength are clearly divided, it depends on how Qin Chuan chooses.

"I can accept."

After hesitating for a moment, Qin Chuan finally nodded. If he wanted to improve his strength, it was impossible without taking risks. For the goal given by the system, he had to take this risk.

"Adults have to have their own ideas when choosing. Xiaochuan, I believe you. There are two v4s here. There is essentially no difference between the two. You choose one."

Xu Hong did not stop him. As a teacher, he put safety first. This was his principle, but the final choice still rested with Qin Chuan.

Qin Chuan's eyes fell on the Ducati V4 in front of him. As a sports car, red is the most popular color.

Xu Hong did not interfere with Qinchuan's final vehicle choice. There was essentially no difference between the two vehicles.

After riding out of the warehouse, Qin Chuan began to adapt to the new racing car. A liter-displacement sports car was not so easy to adapt to. It was difficult for Qin Chuan to control it even for a while.

You must know that this modified Ducati v4 can reach a top speed of 320km/h on this track.

When the speed exceeds the [-] mark, the braking force at the end of the straight line will be terrifying to a level that is difficult to control, and the demand for arm strength is extremely high.

In the morning, people from Lei Yue, who was Qin Chuan's adaptation to racing, came here just to see Qin Chuan's training results and to see if there was anything Qin Chuan needed.

At noon, a familiar figure timidly walked into the racing track.
