The abnormal noise is very serious, giving people the feeling that it is ringing everywhere except for the horn.

Listen closely, the sound of the engine running is normal and rhythmic, and the sound of the six-cylinder gasoline engine is very rich, indicating that there is no problem with the engine.

Ma Jintao pointed to the ditch over there, and the test driver drove the car over, rode on the ditch, and then stopped and turned off the engine. Technicians and workers immediately went over, some went down to the trench to check the chassis, and some got into the car to check the situation from the inside.

The length, width and height of the body are similar to those of Kosda, but the shape has the shadow of a red star sea lion, with a square head and a square brain, which looks like a square box. Of course, other lighting systems have not been installed yet, and now the main thing is to test the chassis, and in the final analysis, the problem of suspension is more prominent.

It took more than half an hour for the technicians and workers to complete the preliminary inspection and count the problems. Immediately, the test driver got into the car, started the vehicle and drove on the paved route test line, pulled up the speed and began to do further high-speed driving tests, including the test of the braking system.

The statistical problems were summarized to Ma Jintao, he looked at it, handed it to Li Lu, and said, "Many places are loose, but the problems inside can only be found when the current test is completed and the chassis is disassembled and checked." Now the main thing is to do the test of the brake system. ”

Li Lu returned the folder to Ma Jintao, and he could see that the posture of the No. 7 sample car running at high speed on the paved road was a little awkward, but it was very slight, and there were few large straights on the paved road, and the body tilted to some extent when turning to cover up the awkwardness of the posture.

"I always feel that the driving posture is not normal." Li Lu frowned and said, stretched out his hand to ask Zhang Weiwei for the telescope, adjust the magnification and look over.

Ma Jintao also took a telescope and looked at it carefully.

"There's a problem with the left front wheel." Li Lu said firmly.

Ma Jintao also saw it, snatched the radio transmitter from the hands of the people around him, and shouted: "Test officer!" There is a problem with the left front wheel! Abort the test! Stop now! ”

"Roger!" The voice of the test driver was accompanied by the sound of noise and noise.

Motorola's walkie-talkies have not yet arrived, and now the Red Star Factory still uses the company-level radio station of the army standard, so there is a person carrying the radio on his back at any time, and one is also installed in the car.

Li Lu's heart was just about to put it down, but he found that the speed of the No. 7 prototype car had not changed much. The top speed should have run to 100 kilometers per hour just now, but now it should be slowing down, didn't the test driver carry out the order?

As soon as the doubts arose, I heard the still calm voice of the test driver on the radio: "Report!" Vehicle brakes fail! The gas pedal is out of order! ”

Li Lu's expression suddenly became solemn, and everyone heard the report of the test driver, and they were all nervous at this time - in the high-speed driving state of nearly 100 highways per hour, the accelerator and brake failed at the same time, which means that the vehicle will even get faster and faster!

"Test driver, please stay calm, is the steering system still normal?" Li Lu took the microphone and asked loudly.

The test driver replied: "The direction can still be controlled!" ”

"When you get to the straight, try emergency braking and pull the handbrake!" Li Lu decisively ordered.

"Understood!" The test driver was not nervous, he came back from the Qinghai-Tibet line automobile unit, and he had not encountered any danger, and it was difficult to shake his nerves when these vehicles were out of control, and now the steering system can still work normally.

The No. 7 prototype made a big curve and then entered the straight. The tester was very cautious, he did not pull the handbrake all at once, but slowly pulled it up, only to find that the handbrake also lost its effect.

"Report, the handbrake is also out of order."

Li Lu immediately decided: "Use the gearbox gear to slow down!" ”

He turned his head to look at the emergency team over there: "The emergency fire team is over!" ”

"Yes!"

The test driver quickly reported, "The clutch is out of order, the gear is stuck!" ”

Several emergency rescue vehicles and fire trucks converted from 212 jeeps rushed past, but it was difficult to catch up with the No. 7 prototype car in the high-speed rush. Everyone's hearts are in their throats. At such a speed, any way the tester takes to abandon the car is very likely to be life-threatening.

Li Lu asked again, "Can the steering system still work?" ”

"Report! The steering is very positive......" Before the tester could finish his words, he suddenly changed the words behind him, "Report! The steering wheel is stuck! ”

Li Lu didn't hesitate any longer, gritted his teeth and said decisively: "I order you to abandon the car immediately!" ”

In front of the No. 7 prototype is the No. 1 test route, which is a high-intensity off-road course. Rushing in at a speed of 100 kilometers per hour, there was only one result - the car was destroyed and people died.

"Report! I'll try again! That's what the test driver said.

He is very aware of the current situation, and the No. 7 car at this moment is very important for the subsequent research and development. These exposed problems, only when the vehicle is stopped intact, can provide researchers with the most accurate data.

The test crew wanted to try their best to get the No. 7 prototype back!

"I order you to abandon the car now!" Li Lu said loudly at the microphone.

At this time, there is still a chance to survive the jump, because there is soft grass on both sides of the straight, which is also an emergency protection measure. If you rush into the No. 1 test line, it is difficult to have a chance of surviving at such a speed.

The test driver did not answer again, he gritted his teeth, his hands and feet did not stop, constantly pressing the brake pedal and clutch, his left hand kept repeatedly pulling the handbrake, and his right hand kept trying to hang the gear, all of which were stuck and motionless at all, and the speed did not change at all.

Seeing that the curve in front of us was getting closer and closer, the No. 7 prototype car would undoubtedly rush out of the corner and fly into the No. 1 test lane in a state of steering failure.

In the last 100 meters, on the radio, Li Lu kept ordering to abandon the car, the test driver turned a deaf ear, he gritted his teeth, suddenly roared, and almost used all his strength to exert force with both hands and feet at the same time.

Unexpectedly, the brake pedal, clutch, and handbrake are all back to normal!

He was overjoyed, pressed the brake to the end, pulled the handbrake, and at the same time stepped on the clutch directly into first gear, all of which had an effect. As if it had been dragged from behind by nine oxen, the speed of the No. 7 prototype car suddenly slowed down. The test driver hurriedly tried to hold the steering wheel tightly and found that the steering wheel was also back to normal.

"Report! The vehicle is back to normal! The test driver was pleasantly surprised to report that the heart slowly lowered with the slower and slower speed, until the car came to a complete stop, he hung into the empty and pulled up the handbrake and turned off the engine, this time he completely put the heart down, and breathed a heavy sigh of relief.

The emergency rescue and fire teams gathered around, helped the tired and paralyzed test rider out of the minibus, and then stood guard on the side to prevent a fire.

Over there, the changes in the No. 7 prototype car surprised everyone, and everyone couldn't help but cheer and high-five, and a major technical accident was avoided.

Li Lu and Ma Jintao were already rushing over in an open-top 212 jeep......
