Chapter 211: Great Yanmar's weakness

Sure enough, as Qin Guan guessed, when Xiang Jing stepped on the brakes, the entire car suddenly slid sideways.

Qin Guan pulled the armrest aside, his body was still stuck to the car door, and the car was about to slide to the side of the field.

In the Prairie City, the roads are almost level with the wild land on the side, so it doesn’t matter if you slide down, and 212 is also capable of off-roading, but if the car rolls over, it will be miserable.

Now, just as the car was about to slide to the side, Xiang Jing’s foot hit the accelerator again, and all four wheels turned up and plowed the ground. The front wheel was flexibly steered by Xiang Jing, and the car was again straightened. , Stopped a few centimeters from the curb.

"Qin Guan, let me tell you, only I can decide what I want to do. Others don't want to interfere with me!" Xiang Jing almost roared towards Qin Guan. At this moment, it was like a roaring lion.

Hedong Lion!

Women’s minds are sometimes hard to figure out. For example, now, Qin Guan doesn’t know why Xiang Jing gets angry. He also feels Xiang Jing’s life is boring here, longing for passion, so he actively asks Xiang Jing to adjust. It's for her good.

Who do you think the old lady is, can make you drink, come if you want, push away if you don't want it?

In Xiang Jing's heart, I don't know why, there was such a nameless anger suddenly, even Xiang Jing herself did not know that she had always been a female character, deliberately hiding her female side. In fact, deep down in her heart, she also yearns for love.

And these days, getting along with Qin Guan day and night, naturally, he has a strange feeling in his heart.

Xiang Jing yelled at Qin Guan, and felt very strange to herself. What's the matter? As a soldier, you have to control your emotions at all times, but your reaction just now is clearly a precursor to emotional out of control.

Strange, so strange.

Xiang Jing's face turned a little red. She stepped on the accelerator and the car continued to drive along the road ahead. On the way, the two of them were speechless. After shouting so loudly, Xiang Jing actually felt that she was in a much better mood. .

The car entered the factory and stopped in the research and development workshop.

There was a roar in the research and development workshop.

Has the engine test platform been built?

Qin Guan was overjoyed at once, and his research and development would be much smoother.

Qin Guan opened the door and was about to walk in. At this moment, a woman's shout came from inside: "Did I let you in? No one can come in without my consent!"

Sandra, this Great Yanmar is even more difficult to deal with.

Hearing the shouts inside, Qin Guan didn't care, and continued to walk inward: "According to our agreement, the output of oil pumps this month should be 1,000 units. Now I will check and accept it and see how much it has produced."

Hearing this, Dayangma stopped talking. In the past few days, I just tested it, and there was no production at all. The output of one thousand units this month would not be reached at all. According to the agreement, if it fails, I will Most of this month’s wages and subsidies will be deducted, these wicked Chinese profiteers!

"But I also helped you build an engine test bench." Dayang Mar said.

"You admit that it was built for us, so why don't you let us see it." Qin Guan said, "This is not producing oil pumps."

Great Yanmar has nothing to say.

The original agreement was that when she was manufacturing the oil pump, she would not let others see it, for fear of being learned about the technology, but now, this is on the engine test bench.

Besides, this workshop was actually owned by Qin Guan before.

Now, Qin Guan was standing in front of the engine test bench, and the Yanmar, who was so angry, stopped going to talk to Qin Guan and continued his test run.

Generally speaking, the factory is not engaged in research and development, it can be directly produced. If the engine is good or not, it will be known when it is installed. However, if you want to know the exact data, you must pass the test bench.

On the test bench, this is an ordinary WD615 engine. The oil pump is manufactured by Dayang Mar. The oil pump with the highest precision is selected from the middle. At the same time, it must be carefully adjusted.

Yes, the high-precision processing of the oil pump is only the first step. The injection time of the oil pump must be carefully adjusted to match the engine.

Even if the oil pump is a good oil pump, it will not work properly if it is not matched. This link is called the oil calibration pump.

Although Dayang Mar is a woman, she is not bad at all in technology. She has adjusted the oil pump to a perfect match with the engine.

The engine on the bench rotates at the highest speed to drive the load behind, and the load displays various data detected.

At the same time, some wires are plugged into the engine to detect other data.

In the end, the data came together, and Dayang Mar actually compiled a set of programs on the Apple 2 computer. At this time, there was a curve on it, which was beating.

"The maximum torque has been increased by 200, and the output is even higher. It seems that if you want to play the role of the engine, the nine-speed box is not necessarily enough, and the 12-speed box is better." Qin Guan said.

The layman watched the excitement, the expert watched the doorway, and the expert would know if it was there. Qin Guan said this, and in an instant, Dayangma was stunned.

"Can you understand?"

Of course I can understand.

The Apple 2 computer is not as good as a calculator in later generations. This Great Yanmar actually came up with a detection software. It is definitely a master. How did so many analog-to-digital conversions do?

Qin Guan didn't ask this, he really didn't understand, but the picture could be understood, because in later generations, as a man, how could he not talk about cars? The curve that measures the performance of a car must also be mastered.

The engine on this test bench, after being tuned by the Great Yanmar, has exploded with an amazing power of 500 horsepower, even if it is a Mercedes-Benz heavy truck, it does not have such a performance against the sky.

At the same time, in order to match it, a gearbox with more gears is needed to bring out its performance.

Even if the reliability is taken into consideration, it is already quite good if it is adjusted to about 400 horsepower. This is the result of high oil pump processing accuracy and high pump oil pressure.

With it, Steyr's heavy trucks can also compete with Mercedes-Benz heavy trucks in the international market, not by cheapness, but by performance!

Thinking of this, Dayang Mar couldn't help it anymore: "Where did you buy this CNC machine tool? Can you buy one for me?"

Do you want it too? A smile slowly appeared on Qin Guan's face. The other party was really not for intelligence. So soon, the other party's weakness was exposed.

When it comes to negotiating with Steyr, I feel more confident.
