Pokémon guide and development

Chapter 423 VTEC System

"Ms. Junsha, do you think Team Rocket is attacking in the east and west?"

On the phone, Shen Qi seemed to mention this casually.

From the mouths of the captured Rockets, the Police Department obtained two strange instructions.

First, the higher authorities asked these newly recruited gangsters to rob the cars on Island 6;

The second is to the beach of the ruins valley.

As for what they were doing on the beach, they didn't know. Anyway, they had just joined the team and it was said to be a trial mission, so let's do it.

As soon as the strange conditions came together, Shen Qishun came to a conclusion.

Junsha agreed. Judging from the available evidence, Team Rocket found some ordinary bad guys, gave them some cheap uniforms, and sold them in the ruins valley to cover the true escape direction of the Kailash Mountain attackers.

Although Athena is not as good as Sakaki, she is still good, but I don't know what Team Rocket is doing by stealing the artificial orb.

Shen Qi has done everything he needs to do, and he feels at ease receiving the bounty. The police department will continue to investigate the following matters.

After ending the call, Shen Qi noticed the news from Hu Zang on social software.

It’s really strange why it took Huzang 7 days to complete the adjustment of the Little Sheep when there was a ready-made engine.

In addition to the engine explosion, the little sheep should have no other big goals.

Before Hu Zang contacted him, Shen Qi would not urge him, so he finally waited for this day out of curiosity.

Call Mrs. Hua Jie, put on the raincoat and go to Hu Zang's car repair shop.

Miss Skirt and Jackrabbit are practicing driving outside these days. They are determined to participate in the spring race, and Geely Dan goes to the ruins valley to practice.

Only Shen Qi, Mrs. Hua Jie, and Duoduo were at home.

"Torazo—"

Outside the car repair shop, a hospitable bronze bell flew over. Shen Qi stroked the lines on the bronze bell and called into the house.

"Hahaha." Hu Zang, wearing a metal mask, walked into the courtyard, "Try it, your little sheep."

Although there were 1000 million questions in his heart, wondering why it took so long to change, the excitement made Shen Qi jump on the little sheep and start driving first.

Calculating the time, I couldn't drive the little sheep for a month and a half.

After the winter race, I headed straight to the Fengyuan area, and then drove the Little Sheep from Qianhong City back to Island 6. The car was unstable along the way, the load was exaggerated, and I was always worried about breaking down halfway. It was just a bad driving experience.

Get in the car, enter the familiar mobile hard drive, connect the mobile phone, Mrs. Hua Jie sits on the temporary seat in the back, and experience the feeling of racing.

"Oh! What a quick start!"

Without any skill gain, the little sheep starts off very motivated.

In fact, the engine has not improved much compared to the previous one. It is a B-class car and has the same specifications as a B-class car.

Unless you replace B-level water flowers and Anomatis, there will not be a qualitative leap.

This is already good... Shen Qi can already compete... Ah————!

"Duoduo, don't gain speed suddenly."

The acceleration suddenly increased, the power suddenly exploded, and the air intake volume clearly felt a surge. Shen Qi hurriedly controlled the direction.

Guji...

Duoduo expressed his injustice. He thought it was Shen Qi who used the style technique turbine.

"not me."

It’s not [Adapted Turbine], [Wild Princess], or Duoduo’s “high-speed movement”. The increase in air intake can only come from the little sheep itself.

There is no feeling at low speed. After the speed is increased, the air intake volume increases sharply. This is a characteristic of the turbine.

At low speeds, the exhaust cannot blow the turbine, which is called "turbo lag." When the engine speed increases, the turbine starts working, and there will be such an explosive speed-up effect.

If Hu Zang installed a turbine on the little sheep, it would really be superfluous.

Shen Qi once clearly told Hu Zang that we have a style technology that can replace the turbine. All we need to do is prepare extra pipelines for the intake and exhaust, as well as an intercooler for cooling the air. There is no need to build an extra turbine and take up space. Also gaining weight.

Thinking about it this way, Hu Zang will not create unnecessary extraneous problems and insert unnecessary turbines for free.

Now I feel that the air intake effect is actually not as good as the turbine, and it quickly reaches the upper limit.

How to achieve the performance of suddenly increasing air intake after speeding up?Mini turbine?

"Duoduo, take a look at the central control system of the little sheep."

The central control system, also known as the driving computer, is an integrated data control system that controls the amount of fuel injection and braking force.

If you want to adjust the central control and make the permissions more radical, you must pull over and connect a laptop to the car's central control system to flash the program.

How many times, Shen Qi can adjust the program during the game.

For simple electronic devices, Duoduo does not need to enter them, just stay close or touch them.

Soon, Duoduo discovered the modified parts of the central control system.

A program has been added to bridge the No. 2 camshaft when the speed increases and natural air intake is insufficient.

"Camshaft..."

Whether the engine is L4, V4, V6, or V8, the piston movement of each cylinder generates power.

Inhale (air and energy enter together), compress, explode (do work), and exhaust.

The initial intake of air is to use the camshaft to open the valve and let the air in. The subsequent compression and explosion generate high temperature and high pressure in the sealed environment, and no air can be taken in halfway.

The meaning of the turbine is to directly blow high-density air in during the intake stage to increase the air intake volume.

The current Little Sheep does not have a turbine, but has a central control computer that bridges the No. 2 camshaft, and the air intake is significantly improved.

This means that the No. 2 camshaft is longer, opening the valve deeper and giving more air intake opportunities.

The normal camshaft is used in the low-speed gear, and the long camshaft is switched to the longer camshaft when the speed is increased. Without the turbine, many air intake problems can be solved by adding only a few parts to the matching system.

VTEC, variable valve timing and valve lift electronic control system (VariableValveTimingandValveLiftElectronicControlSystem).

To put it bluntly, the valve is adjustable. "Lift" is simply described as the depth of valve opening. The electronic control is of course the program of the central control computer.

As for this system, it is awesome. It is a great invention, but its usage rate is not that high anymore.

Family cars are OK, but variable valves are relatively rare in the racing field.

Because of the turbine.

In the same way, air is forced into the engine, and the variable valve is opened longer. In the final analysis, the air is allowed to flow in naturally according to the vehicle speed;

Turbocharging is done inward. The faster the speed, the higher the efficiency. The upper limit is much higher than deepening the valve.

Therefore, turbocharging has the effect of upper replacement.

So what about variable valve lift + turbocharging?

In most cases, it is not necessary. Stacking beds and building houses will not achieve 1+1 greater than 2 after repeated effects, unless someone designs some unique and unique patterns.

Most of the races are mountainous and there are a lot of difficulties. Not many A-class cars dare to stack like that, and not all engines can have VTEC.

For example, the homogeneous compression ignition technology of Rainbow Flying Sword, without a complete system, how can other cars dare to copy it casually?

"Hu Zang, so awesome..."

In a sense, VTEC was replaced by Turbo Upper, but its meaning to Shen Qi was different.

Hu Zang knew that Shen Qi's turbine was a style skill. When the style skill was not used, the little sheep could only adjust the air intake with skill gain.

After installing the variable valve, when the speed requirement is not so extreme, Shenqi can save the energy of using the turbine and can increase the air intake through the intervention of the No. 2 camshaft.
