Chapter 486: Conquering DVVT

It seems that there is no time when there is not enough manpower since the beginning of the founding. Pen × fun × Pavilion www. biquge。 info

Even though it has been upgraded twice, after Li Fanyu determined the R&D task of Hongguang, the R&D engineers are still busy enough.

The stinky boys came back from the United States for less than two days to be comfortable, and it became a miserable day of working from 5 to 9, and even stumbling into the night.

Because the U.S. market is now in the development stage, the follow-up research and development of F150 occupies nearly half of the human resources, so there are only more than 100 formal R&D engineers in the R&D center.

Although after the upgrading of the group, with the expansion of the company, the R&D center has carried out a certain degree of recruitment, as Li Fanyu's alma mater, Amagi Engineering Nature is within the scope of Zhengxin's care, and a large number of graduate students have entered Zhengxin's part-time work and study. The three major universities in Qingbei and Kazakhstan have also successively added some graduate students and doctoral students.

However, these people are still lacking in ability and experience, and need time to grow. At this stage, these people can only help engineers get started, complete some simple parts such as modeling and some testing experiments.

In view of this situation, Li Fanyu threw the group's affairs to An Ning, and he sat in the R&D center to supervise and coordinate the R&D progress.

This job originally belonged to Xu Fufang.

Although it is supervision, the specific work is also very complicated. At the beginning of the R&D work, there were so many things that were designed. Zhengxin's ecological model is a bit special, not only responsible for the research and development of the whole vehicle, but also needs to bear part of the things that should belong to the supporting factory. Therefore, the coordination work is enough to bring Li Fanyu, the CEO of the company, back to his original shape and transform into a technical otaku again.

The research and development work has been carried out for more than ten days, and for more than two weeks, Li Fanyu has stayed in the industrial park for more than two weeks. In order to pat himself on the back, Lu Heming specially renovated the luxurious office for him, which almost became his third home.

For Li Fanyu's direct involvement in R&D projects, Zhengxin's engineers have long been surprised. But the new team members still seem excited.

Li Fan is foolish!

Although no movie star or singer is famous, in the field of automobile industry, this name can really be said to be legendary among the new generation of industrial people in China. Every day, in his spare time after arranging specific work, looking at a group of adoring eyes, Li Fanyu was under a lot of pressure......

Because the DVVT engine is the core of Hongguang's model, it is the first part that Zhengxin started to develop. With the cooperation of the R&D team, a prototype has been made.

What is now underway is the final step before the engine goes into mass production, testing.

Different from the testing methods of other car companies in the Chinese automobile industry, because the full set of test equipment is purchased by Anning from overseas, Zhengxin actually adopts the European standard test method.

When it comes to the engine, it's even more complicated.

This is something that can't be helped, the Europeans still have very high requirements for the reliability of machinery, which is why Li Fanyu is willing to spend a lot of money to introduce these equipment.

As the base camp of the automobile industry, Europe does have a set of standards in the formulation of standards. These are all things that are worth making up for and learning.

Take this engine test as an example, in the part of bench testing, Zhengxin now needs to do four links.

There are four engine experiments: MS-IID, IIID, IIIE and VD.

MS-IID is used to calm the ability of the automobile engine to prevent rust on the valve block under the conditions of low temperature and short-distance situation. MS-IIID, IIIE and VD are used to calm the ability of lubricating oil to oxidize at high temperature, thicken, precipitate sludge grade paint film, and resist wear of the engine.

Compared with the SH/T series of tests adopted by the Ministry of Industry and Information Technology of China at this stage, the MS test is significantly more complex and complete.

Starting from the V8V10 engine of QS15, Zhengxin has used this set of test standards. Therefore, as long as it is an engine that has passed the Zhengxin test, there is no pressure at all after passing the audit of the Ministry of Industry and Information Technology.

As a low-end, low-cost engine, the P-TEC engine itself has no technical difficulties to talk about. The only trouble is with the camshaft sprockets, which are unique to DVVT technology.

Because all the engines manufactured by Zhengxin before are relatively high in terms of positioning. Therefore, in order to pursue the quiet performance of the engine, the cam chain shaft has always been driven by a belt. However, the P-TECDVVT needs to change the intake and exhaust valve states very frequently, and if it is still transmitted by belt, it will not be able to pass the durability test.

The embarrassing thing is that the supporting manufacturers in the industrial park do not have the experience and technology to manufacture this kind of sprocket structural parts......

Therefore, in this link, Zhengxin mobilized the procurement department to find an international supporting factory.

If it weren't for the delay in the process, I'm afraid that the engines would have been ready for review by now.

Through this, Li Fanyu felt that there are still a lot of weaknesses in the basic industry in China. But this is not something that can be solved on his own, or in a moment. For this, it is also helpless.

After overcoming the difficulties, the P-TECDVVT engine quickly passed the audit of the Ministry of Industry and Information Technology. The registration of various technology patents was handed over to the legal department of the group, and Li Fanyu led the team to carry out the research and development of the rest of Hongguang.

As a national-level satellite MPV, Hongguang's body technology can be said to be the simplest project that Zhengxin has done. After the engine problem is solved, the progress of the entire model can be described as a thousand miles in a day.

Up to now, Zhengxin has become mature in terms of R&D mode and process, and has its own model laboratory. Therefore, even if you do not rely on an X3D metal printer, you can complete the manufacture of prototype parts independently.

Seeing such progress, Li Fanyu breathed a sigh of relief.

The progress is gratifying, isn't it...... It seems that he can be lazy again...... Oh no! Let go and let the grassroots team temper themselves!

threw the coordination work in hand to Lao Zhang, and instructed Wang Rui, who was developing the performance version of the A4A8 car, to take over the next step of body and chassis tuning. Li Fanyu finally walked out of the industrial park for the first time after staying in the R&D center for more than ten days.

After the Zhengxin A8 rolled off the assembly line, Li Fanyu kept one for his own use. However, because he was too busy at that time, he did not modify his car. Although his driving skills are enough to kill 90% of the human beings on this earth in seconds, Li Fanyu usually drives very steadily.

After walking unhurriedly for more than ten minutes after coming out of the industrial park, he felt that something was wrong.

On the inverted mirror, a large cargo that didn't look like it was loaded seemed to be behind him after coming out of the industrial park.

Li Fanyu frowned;
