Rebirth of the Auto Giant

Chapter 273 Test

In a blink of an eye, October came and Lin Zhengtang's wedding was held. Wang Shi, as the master, gave "three pieces" of new TV sets, washing machines and refrigerators. Of course, there were also many red envelopes.

When the room allocation list was announced, the happiest people were the ordinary employees who were able to live in the dormitory.

You must know that there are 30,000 employees in the base, and only 240 can live in the collective dormitory. What does this mean? It means that he is the best among the 30,000 employees.

Today, Wang Shi is in the R&D center discussing with technicians from the R&D department about improving the engine for loader engineering vehicles.

"In view of the special working conditions of loaders, our current tcd6114qb automotive engine is no longer suitable, so we need to improve on the original basis of tcd6114qb and improve various performance indicators, especially the torque reserve rate." Wang Shi said.

Loaders are different from cars. Loaders work with a huge 3-cubic bucket in front. Under such heavy-load conditions, the engine requires a high torque reserve rate.

The current automotive tcd6114qb torque reserve rate is only 15, and it must be at least greater than 20 to be successful.

At the same time, the oil pump was also upgraded, and Wang Shi made the drawings of the PT100 engine.

Improve the high-pressure combustion and confiscation of the high-pressure oil pump, and the atomization can better reduce fuel consumption.

"At the same time, we should also improve the enhanced cylinder liner, piston ring and air compressor." After Wang Shi finished speaking, he took out the hydraulic oil pump, piston ring, cylinder liner and other drawings from his bag and handed them to Xing Lichong, and said, "

This is the draft I designed. If you prove it and there are no problems, hand it over to the engine production workshop to produce a sample and test the car." After that, Wang Shi left.

As for the demonstration, people from the R&D department will naturally handle it.

In this design upgrade, Wang Shi also deliberately left several flaws to see if the so-called talents in the R&D center could find them.

The next day, Xing Lizhong came to Wang Shi's office with the results and found several incorrect data.

Wang Shi also supplemented the original correct data, and finally decided to have the engine production workshop produce a prototype for trial operation.

The product research and development department has equipment specifically designed to test various engine data. These equipment were developed by Wang Shi and some universities.

The data was obtained through testing.

Model:tcd6114zgb

Cylinder diameter (mm) x piston stroke (mm): 114x135

Calibrated power (kw): 160

Calibrated speed (r/min) 2200

Fuel consumption rate (g/kw.h):200

Torque reserve rate:＞20%

tcd6114zgb represents Tang Dynasty Power’s 6-cylinder 114mm stroke turbocharged loader engineering machine special engine B model.

This improvement reduced the power and increased the torque reserve rate from the original 15% to 20%.

At the same time, corresponding improvements were made to the four-cylinder engine tcd4105 to increase the torque.

"Call Shandong Lingong and Yigong to install it on their loaders and test it. The personnel from the technical department will send technicians to follow up at any time to observe whether the theoretical design requirements can be met." Wang Shi said.

This time in the complete machine factory, the zl20/zl30 loader produced by Yigong is equipped with a tcd4105 four-cylinder engine, and the Shandong SDLGong zl50 loader is equipped with a tcd6114zgb six-cylinder engine.

Product testing is also an important step, which is to verify whether the actual situation of the product is consistent with the theoretical data.

Finally, one verification machine of each model was produced and sent to Yigong and Shandong Lingong respectively. The director of the R&D Center and two technicians from the R&D Department, as well as Wang Mingjing and Lin Zhengtang from the Service Department

Went to two companies to participate in product verification work.

Shandong Lingong received a call from Tang Dynasty Power Technology Center and immediately informed their factory director.

"The power of Tang Dynasty is so fast?" Director Zheng said in surprise.

"No, if this is a state-owned enterprise, it won't take more than a year and a half to come up with a prototype. This is the advantage of private enterprises. They move very quickly. They are not like state-owned factories, which have complicated procedures and have to report to each level when making something.

"The director of the product department said.

"It seems that the power technology of the Tang Dynasty is also very strong, but they have ready-made cars, and they can improve them very quickly based on the original cars."

"Let them bring the engine over immediately, and also ask them to send technicians over." Director Zheng gave some explanations.

As a test prototype, Tang Dynasty selected a mine as a test site to start work, and sent technicians from the R&D center to test the data, as well as service department personnel as support.

The tcd6114zgb engine is an improvement on the automotive engine tcd6114qb. They are mature technologies in terms of reliability and economy. In the past two months, the car has mainly tested the reliability of each improved component.

Are there any differences between sex and various indicators as before?

After more than a month of testing of various types of engines on loaders, the data finally came out.

The data are all within the theoretical test range.

The car worked during the high load hours of the mine and never broke down.

This made the mine very happy, and the new car was available for free for more than a month.

Shandong Lingong's vehicle sales staff also recommended to the mine on the spot that they would soon produce a 5-ton zl50 loader powered by Tang Dynasty engine.

"This car is a new car, and you have seen it. In this month, you have also seen the test data obtained by the R&D personnel of Tang Dynasty Power Company. You also know that Tang Dynasty Power Company's engines have been

High reliability and high-quality service, especially the three-guarantee service, have been recognized by the market. Now that we have tested it, we have decided to sell this new car at a 30% discount. This is a rare opportunity. You are near the water, first come first served. If you don’t want it,

We sold it to others," said the sales representative of Shandong Lingong.

This is the result of their discussion with the engine last night.

After frequent discussions, the two parties decided to sell the test prototype at a 30% discount after the test was completed.

When I heard that the other party offered a 30% discount, this was a new car that was only 11 and a half months old, so I saved a lot of money, so don't be an idiot.

When I responded to the above, the zl50 loader finally stayed.

The remaining zl40 and zl30 loaders were also sold to other companies.

Tang Dynasty's engines have been tested and various data have been tested. At the same time, the recruitment of employees is also in full swing.

Now the whole Beijing is very lively.

After seeing the notice posted outside the base that morning, those elderly people whose families had unemployed young people secretly decided to bring stools and queue up all night in the evening.

As a result, the night shift guards at the base discovered a strange thing. Since midnight, many people had brought deck chairs and lined them up on the street outside the gate. Soon, many people seemed to have agreed upon it and lined up in a row.

Short and long queues.

The people in the security department knew the purpose of these people's visit and saw that they were old. In addition, the place they occupied was not within the control of the base, so they left it alone.
