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

Its functions are firstly transmission and secondly coordination. The latter is the most important, the most delicate, and also the easiest to tamper with.

The upper end of the timing belt is generally connected to the engine's valve, and the lower end is connected to the piston. The movement of both is driven by the timing belt, and the two require very matching movement patterns.

If one of them is a little slow, big problems will occur.

This means that once there is a problem with the timing belt, the timing of the valve movement trajectory and the piston movement trajectory will not match, causing the internal rhythm of the engine to be disrupted.

As for how to cause timing belt problems, it is simple. If the belt is slightly loose, it will cause problems, such as replacing a new belt with an old one.

After long-term use, the old belt will become loose, the transmission frequency will slow down, and it will disrupt the original rhythm set inside the engine.

So Qin Chuan would say that the place that is easiest to tamper with and hardest to be discovered is the timing belt.

There is absolutely no difference between the new and the old, and you can't tell it with the naked eye.

As for the easy part.

First of all, anyone who has ridden a bike for a long time will know the role and shortcomings of the timing belt, because it needs to be replaced and maintained every 10,000 or 20,000 kilometers.

Some veteran riders often encounter their cars stalling or losing power for no reason. When they go to the 4S shop for inspection, they usually find that the problem is caused by a loose belt.

This is common knowledge known to almost all veteran riders.

Secondly, it does not require very advanced skills. As long as you can remove the engine casing, you can see the belt at a glance and tamper with it. It may be difficult for cyclists, but it is easy for ordinary staff and riders in the paddock to do it. It's just removing an engine casing. Everyone in the paddock sees it every day, so it's not difficult to practice it.

"This is an old belt. I'm afraid the person who came here is from the same industry as me."

John took off the belt and pulled it with his hands. Then he put it back and took out an instrument to measure it before speaking solemnly.

Even for an old guy like him, it is difficult to tell a new timing belt from an old one with his hands. He has to use equipment, flick the belt with his hand, and then measure the frequency of the belt's vibration to analyze whether it is tight or loose.

Is the thief also a technician?

Hearing this, an idea came to the minds of everyone in the P room. The Likana staff on the scene looked at each other. If it was a technician, then who would be the most suspicious? It must be them.

After all, this is their own territory, so theoretically it would be more convenient to take action.

The police behind the security department also looked around when they heard this, and it was obvious that they had the same idea.

“It doesn’t have to be a mechanic, it could be a driver.”

Qin Chuan spoke up at the right time to remind him. The Minister of Security nodded when he heard Qin Chuan speak. The one with the most face here is not the beautiful boss of Likana, nor the old senior John, but Qin Chuan.

With his reputation and as the boss of a super fleet, the Minister of Security attached great importance to Qin Chuan's speech.

A policeman behind him heard this and took note again.

"Well, what Xiaochuan said is right. Drivers can also tamper with the belts. Although drivers don't understand the essence of car repair, their appearance skills are very good. I dare not say much else. It is not difficult for a senior professional driver to dismantle the engine casing by themselves."

Annabelle also nodded, and she agreed with Qin Chuan's statement.

The drivers have been driving for more than ten years. They don't know how to repair cars, but they have some experience in watching their technicians repair cars for many years. They can't repair it by themselves, but it is not difficult for them to just remove the engine casing.

As for changing the belt, it is actually not difficult. The difficult part is the testing and adjustment.

If you ask a driver to check if there is a problem with the belt of a car and to repair it, they may not be able to find out the problem, but they can replace it with an old belt.

The security staff wrote down everything, and the Xiaoliguo policeman following behind them nodded.

After a brief summary, the case was preliminarily understood. Seeing the Minister of Security nod, Annabelle ordered her men to start working, and everyone began to prepare for the competition. However, the people from the Security Department and the police did not leave, but pulled Annabelle aside for questioning.

Several police officers also began searching the room for evidence and investigating surveillance footage.

"Boss, do you want Neil to check it out?"

Sitting back in her seat, Jenny spoke softly.

"No, this is a racetrack, the police are very efficient, there is no need for us to intervene."

The public security in foreign countries is not very good, but Qin Chuan does not think that the police station outside is just for show. The Muse Circuit is the most classic and famous circuit in F1 and GP. The monitoring equipment here is too complete. It is only a matter of time to find the murderer. It is completely useless for him to worry about these things.

Jenny nodded, stood behind Qin Chuan again and stopped talking.

On the field, as the race resumed, all drivers had arrived at the starting point. Just like at the GP start, everyone stood in their starting positions one by one. Chen Ye and Wang Kaihua sat in the car and looked at each other. Both were in the third row.

Chen is also in the first position on the far left of the third row, and Wang Kaihua is on his right, in the middle of the third row. Their positions are exactly next to each other.

Unlike GP, there were not so many reporters and staff around them. Each person had only one team employee in charge of holding the frame, which looked extremely shabby. Even the staff holding cameras were pitifully few. Unlike GP, where one rider had several cameramen following him, there were only three photographers at the entire starting point, and there was only one photographer for every ten riders.

"Kaihua, who do you think is targeting us?" After glancing around and making sure the photographer was not there, Chen Ye leaned his head out and asked curiously.

He had just learned that someone had tampered with the timing belt of their racing car engine.

They all understand this stuff. Before joining CA21, they had no money to practice driving, so they often lived frugally and were reluctant to replace many racing parts. They would almost always replace them when they were unusable.

Among them, the timing belt is one of the parts he is reluctant to replace. Given the intensity of his training, he needs to replace it every few months.

It costs a lot of money to replace it once, so he often delays the replacement for a while. For example, if the regulation requires replacement after 20,000 kilometers, he will wait until 30,000 kilometers before replacing it, thus saving some money.

Because this thing generally does not break, but he dare not delay it for too long. The reason is that the elasticity of the belt will deteriorate after a long time of use. Once it breaks, the engine will be scrapped directly. Even if the frequency of continuous transmission becomes slower than before, it will cause the internal trajectory of the engine to be disordered, causing sudden stalling, power weakening and other problems.

He once encountered a sudden stall when he was exiting a turn. The car was fine when he entered the turn, but when he stepped on the accelerator to exit the turn, he found that the car could not straighten up and had no power. He was so scared that he was almost hit by the car behind him.

Fortunately, he was just training at the time, not competing. If he had been competing, he would probably have died. I still feel scared when I think about it now.

"I don't know. Maybe it's an old enemy of this team. We haven't offended anyone since we first came here."

Wang Kaihua was also puzzled. His family was better off than Chen's and could be considered wealthy, but he had heard of timing belts and understood them.

"Didn't you offend anyone?"

Chen Ye was in deep thought. He didn't quite agree with this statement. He felt that their coming here had offended people, at least those two people.

At the same time, the police in room P also temporarily identified two suspects.

That’s right, they are the two original drivers of the Likana team, especially Tuca.

Tuka had an argument with Likana's people yesterday morning, so he had the most complete motive and suspicion in terms of the crime.
