Chen Dongqiang's face was a little ugly. He really didn't understand what turbo lag was. After all, they had been studying naturally aspirated engines. Advanced luxury cars also used supercharged engines, and the superchargers were directly driven by belts. , with the engine running together, there will be no hysteresis.

As for turbocharging, although it was said that it was used on airplanes during World War II, it was rarely used in civilian vehicles, and he was not very clear about the specialization in the technology industry.

Now, he understands, the reason is very simple, if you get a small turbo, the exhaust gas from the engine can easily blow it up, so that the time for the turbo to intervene is earlier, but... the disadvantage is that the small turbo, the air blown in Limited, especially after continuing to increase the speed, when more airflow is required, the air blown in by the turbine will not be enough, that is to say, taking care of the hysteresis of the turbine will not allow the engine to obtain more power.

150 horsepower, can it be achieved?

Qin Shaoyou has continued to work, connected all kinds of pipelines, installed all kinds of peripherals in place, the assembled engine looks very atmospheric, especially, Qin Shaoyou specially sprayed the cylinder head with a layer The red paint looks different.

Xia Miaomiao didn't say much all the time, and looked at Qin Shaoyou with admiring eyes. Although Qin Shaoyou was only a small worker who had been in the factory for half a year, his every move seemed to be at the level of a master.

The nerd Wang Jun was holding a camera, snapping and snapping photos, and the entire assembly process was recorded in place.

Chen Dongqiang swallowed a mouthful of spit, and said again: "We don't have a dynamometer here, so we should send this engine to the engine assembly workshop for testing there to see if it can meet the design requirements. If it fails to start, It’s also convenient for debugging there.”

For an engine that has just been assembled, it is not bad to be able to start it successfully, especially for electronic injection engines, it is necessary to repeatedly adjust the ecu to get the best power output from the engine. Qin Shaoyou has just assembled the engine now, if the program If it is not right, it will be difficult to start, but now Chen Dongqiang is asking for a horsepower machine!

This is absolutely difficult for the strong.

Hearing Chen Dongqiang's words, Gao Zhongzhong couldn't bear it any longer: "Hmph, I used to say that our engine can't be built at all, without a foundation, it's just a castle in the air. Now, our machine is assembled, and I want to ask us to eat it all at once." Fat man, if this engine can't output 150 horsepower today, should we go to the factory leader to belittle our engine again?"

"Everyone is an expert. This new engine has just been built, and it will be good if it can be started. Shaoyou said it would take a year, but it is less than three months, and there are still nine months to debug it. , it won’t be too late to get on the test bench next year’s National Day.”

People here are a little angry.

Asking to go on the test bench now, the ghost's intentions couldn't be more obvious. In the past, he belittled every day, and all kinds of gossips were said a lot. Now, it's time to find fault again?

Chen Dongqiang's face was ugly, and he wanted to continue to argue, but Qin Shaoyou had already said: "Chen Gong, you can take a look at it, our engine is all waste products, but we don't use any parts provided by the engine branch factory. Now, let's put Bringing this engine to the engine branch is just to test the power, and you suggested it. In the future, don’t spread rumors about how much help my master has provided me. My master’s help is all spiritual."

Chen Dongqiang was about to go into a rage, when did he spread rumors about you?I thought, there is no chance at all, but before he could say anything, seeing that An Ran had put on a new tape and continued to pick up the Walkman, Chen Dongqiang could only squeeze out a smile.

"How is it possible?" Chen Dongqiang said: "We are all workers in the same factory, how can we do things like spreading rumors behind our backs? If it succeeds, it will be a big event in our factory, and the journalists are here too, and when reporting, we can do more dry stuff."

"Okay, in front of the reporters and friends, no one would dare to spread rumors. Let's send the engine to the test bench of the engine branch factory and test it."

Gao Zhongzhong is a little anxious. It is good that this engine can be started, and it needs to be tested. What if it is not as good as it was before the modification?We've had enough of the limelight today, just light it up and give it a try, why do we need to go to the test bench?

However, looking at Qin Shaoyou with a confident look, if he can really succeed, he will definitely be a big star!

"Come on, everyone, do me a favor." Qin Shaoyou shouted.

A group of people pushed the engine stand and went straight to the engine assembly workshop.

Today is New Year's Day, except for the lively spots in the technical department, other places are quiet.

At the door of the engine assembly workshop, Liu Shengli was sitting on a big rock, smoking a cigarette.

"Director Liu, why are you sitting here?" A young man from the factory security department on patrol asked.

"Ah."

"Director Liu, there is excitement over there in the technical department, haven't you gone over to take a look?"

"No."

"Old Liu, are you sure that the people from over there will come?" At this moment, Sun Bingwen rode a bicycle and galloped over. He parked the car at the door, set up the car ladder, and shouted to Liu Shengli Said: "The people over there will come soon, and they will test on our test bench."

Liu Shengli threw his cigarette butt on the ground, stepped on it hard, and said, "I knew that Xiao Qin would not let me down!"

During this period of time, Liu Shengli has been waiting for Qin Shaoyou. He can provide Qin Shaoyou with various parts, even for special production, but Qin Shaoyou didn't open his mouth to him. He knew that Qin Shaoyou was doing this to prevent some people from gossiping.

Liu Shengli is a little annoyed, what are you afraid of, it is legitimate for us to develop a new engine, and it was passed at the factory affairs meeting, so are you afraid of a few grandchildren telling nonsense?

Yesterday, he heard that the engine was going to be assembled today. He didn't sleep well all night and came to the factory before dawn. He lingered in the technical department for a long time, but when more and more people gathered, he returned Arrived at the engine assembly shop.

Liu Shengli is full of expectations and full of confidence.

The improved engine was finally put on the test bench.

"This red head is so beautiful." Liu Shengli said.

"Well, the red head is festive, so our engine will be referred to as the red head machine from now on." Qin Shaoyou said: "Friends from the reporter, take a photo for us as a souvenir!"
