The third Spring Festival after Zhou Jingming's rebirth came as scheduled.

As before, this year's Spring Festival is still spent with He Yingqing and He Yingxun returning to their hometown together, no matter how prosperous Shencheng is, it is not as strong as the New Year's flavor of his hometown.

"Mom, after the New Year, you can go to Shencheng with my dad and Xuan'er, there is a place to live there, you don't have to worry about this. After Xuan'er arrived in Shencheng, she could still receive a better education. "Chinese New Year's Eve, Zhou Jingming said while wrapping dumplings.

Last year, he asked Zhou's mother to come and live with him, but Zhou's mother never agreed. Now the benefits of Xunming Gear Factory are getting better and better, and the factory has also built a new family compound, and if Zhou's mother lives in the past, everything is convenient.

"Ah Ming is filial, you can go with me, you can usually go to the kitchen to help out or something, and it can be regarded as sharing some for Ah Ming. As soon as Zhou's mother wanted to speak, Zhou's father on the side persuaded her.

"Auntie, just come, you will get used to living and living. ”

"That's it, you stay at home alone, and your brother-in-law is not at ease. ”

He Yingqing and He Yingxun also helped persuade them.

Zhou's mother, who was rolling dumpling skins, couldn't help but stop what she was doing, "I'm a rural person, I don't know anything, I don't embarrass Ah Ming when I go to the city." ”

"Mom, the entire gear factory is mine, who dares to say that you are ashamed. Besides, you have to think about Xuan'er too. As he spoke, Zhou Jingming pinched Xuan'er's little face, "Do you want to go to the city with your brother?"

"Yes. The little girl raised her face and said sweetly.

"Then I'll be with you for a while?" Zhou's mother wiped her forehead with the back of her hand, "I always feel unsure." ”

In this way, Zhou Jingming successfully persuaded Zhou's mother to live in Shencheng together after the New Year, and Zhou Jingming only stayed at home for five days, and returned to Shencheng alone on the fourth day of the Lunar New Year.

The loading test agreed with Bosch is scheduled for the eighth day of the Lunar New Year, and Zhou Jingming will arrive in Stuttgart at least one day in advance to prepare.

After buying a ticket for the morning of the fifth day of the Lunar New Year, when Zhou Jingming arrived at the Bosch headquarters, it was already the morning of the sixth day of the first lunar month local time.

After a brief rest, Zhou Jingming found Royce in the afternoon and was ready to discuss with him the specific details of the loading test.

"In addition to verifying the performance of the in-cylinder direct injection engine, we also want to compare the advantages of the in-cylinder direct injection engine and the ordinary engine in terms of performance, so for this test, we plan to take the form of a comparative test. After Zhou Jingming arrived, Royce began to introduce the specific details of the test.

"What about the car, which model of which company?" Zhou Jingming continued to ask.

"Volkswagen's Golf. We have reworked the original engine of the Golf and found three new Golfs, except for the different injection methods of the engines, all the other configurations are exactly the same. Royce replied.

"Is it determined that the restructured engine can give full play to the performance advantages of in-cylinder direct injection?" Zhou Jingming asked with some concern.

"Don't worry, our engineers have already done the whole machine test, and all indicators are normal. Royce smiled and replied confidently.

Bosch's experience in engine testing is very rich.

"In addition, in order to ensure the objectivity of this loading test, we also invited a third-party evaluation agency to participate in this test, including Volkswagen's test team. After a pause, Royce added.

Zhou Jingming smiled and did not answer, Bosch invited Volkswagen to participate in the loading test of direct injection in the cylinder this time, I am afraid that it is not only to ensure the objectivity of the experimental results, but more, I still want to take this opportunity to sell this engine technology to Volkswagen, after all, Bosch has paid a lot of price for this technology!

However, in any case, Bosch has done a very good job in preparing for this loading test, especially the participation of third-party evaluation institutions, which is worth learning from in China.

Time flies quickly, and in a blink of an eye, it is February 26th, which is the eighth day of the first lunar month.

Volkswagen car proving ground.

In view of the fact that Bosch does not have a special test track for automobiles, this time the loading test of the in-cylinder direct injection engine was placed at the Volkswagen test site.

Early in the morning, Zhou Jingming and others came to the test site, and the technician in charge of the loading test was conducting the final inspection of the three golf cars on the track before the experiment.

After the Bosch technician inspection, the Volkswagen technical team involved in the test also came forward to inspect the three experimental Golf cars, and the main purpose of their inspection was to check the fairness of the test.

"The car in the middle is equipped with direct injection, while the car on the left is ordinary carburetor injection, and the car on the right uses single-point EFI. When Volkswagen's technical team inspected the vehicle, Royce, who was standing next to Zhou Jingming, whispered.

After a while, the head of Volkswagen's technical team also nodded at Royce, indicating that there was nothing wrong with the inspection results.

You're all set!

This loading test is mainly to test the power and fuel economy of the engine, and the first thing to carry out is the power test.

The three drivers involved in the experiment were ready to go, sat in the car and started the vehicle at the same time, and only waited for the tester to give the order, they could step on the accelerator and sprint forward.

Sensors are installed on the engine of each vehicle to measure the maximum output torque of the engine and other parameters in real time, and sensors are also installed on the vehicle to measure the acceleration time of the vehicle to 100 km/h.

With the start of the vehicle, Zhou Jingming's heart was also nervous, there was a lot of sweat oozing out of the palms of his hands, and the exhaust pipes of the three cars, white emissions bubbled out of the exhaust pipes, if you look closely, you can see that the exhaust gas emitted by the direct injection engine in the middle of the cylinder is obviously thinner than the other two cars, which shows that the fuel is burned more fully in the engine.

With a "beep" whistle, the three cars that had been prepared a long time ago, like wild horses on the loose, galloped quickly on the runway.

The photographer in charge of this shooting was also the first to capture this dynamic test.

On the runway, the Golf equipped with direct injection in the cylinder, in a moment of idle start, it is obviously faster than the car on both sides, and the technical advantages of direct injection in the cylinder are clearly reflected at this moment!

The advantages are still expanding!

Not long after the car sped out, the Golf in the middle emitted a beautiful engine sound, and it was only a few centimeters away from the cars on both sides, and suddenly it was pulling forward at a speed visible to the naked eye.

In a matter of seconds, the front of the Golf in the middle clearly outpaced the cars on both sides!

The spectacle of this experiment is not even lower than that of ordinary car races!

Then, before Reuss and the others had even seen enough, the Golf in the middle crossed the end of the test with an indomitable momentum!

At this time, the other two cars had been thrown away by it nearly half a meter away!
