Automotive Black Technology Chapter 1579: ：Competition!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
Seeing that the Williams No. 2 car reversed the situation in an instant and surpassed himself, Hamilton's heart was churning no matter how good his mental quality was!
It can be said that among all F1 drivers, no one understands the performance of his car better than him. No one knows the superiority of the engine behind him better than him!
Since 2014, F1's engines have undergone earth-shaking changes, from the 2.4V8 to the bold introduction of the 1.6LV6 turbocharged hybrid engine. The engine speed limit will be reduced from 18,000 rpm in the V8 era to 15,000 rpm, the turbine speed will be 125,000 rpm, and the maximum injection pressure of direct fuel injection technology has reached 500 Pa.
Correctly speaking, this kind of F1 power cannot simply be called an "engine", but should be called a "power unit" because the new power unit introduces an energy recovery system - ERS.
F1 already had a pure kinetic energy recovery system - KERS, which recovers braking energy from the rear axle through a compact generator/motor system. This is the same principle as most civilian hybrid models on the market today. of.
But the new ERS goes a step further. In addition to the original KERS system, it will also use another set of motors connected to the turbine and heat exchanger to convert the excess heat energy of the engine into electrical energy and store it.
For example, with the KERS system in the V8 era, drivers can receive an additional power output of 80 horsepower for 7 seconds per lap. Drivers with the 2014 version of the ERS system can receive additional power output lasting up to 33 seconds per lap, with a power of up to 161 horsepower!
Not only that, the new power unit saves 30% of fuel than before. In the V8 era, F1 carried about 150 kilograms of fuel to complete the journey, but now it only needs to carry 100 kilograms.
This change has brought about huge changes in the entire pattern of F1 - in this field of ERS, Mercedes-Benz AMG is the well-deserved number one.
The story that happened later was rather bloody. Since the beginning of this new power unit era, the Mercedes-Benz team has completely dominated F1 by virtue of its power advantage, causing other teams to complain and fans to complain frequently.
But in fact, Hamilton knows that the advancement of Mercedes-Benz engines does not stop there!
What makes him most satisfied with the engine in recent seasons is the engine's thermal efficiency. Behind him, the thermal efficiency of the Mercedes-AMG high-performance AMG-HPP engine has reached an astonishing 47%.
This is the best-selling engine among all F1 racing cars!
In layman’s terms, “thermal efficiency” refers to the extent to which an engine can convert fuel energy into power to propel the car in front of the car. A typical car can only use up to 30% of the energy, and the other 70% is lost through heat. It is lost through mechanical friction and other means.
The high thermal efficiency of the Mercedes-Benz engine means more surging power and more sustained acceleration capabilities.
With this advantage, Hamilton watched his opponent retreat from him countless times, and saw his opponent's annoyed but helpless eyes in the rearview mirror countless times.
But now, this feeling is happening to him, and it is so sudden, and it is inflicted by such an opponent that he has never seen before!
"FK! What's going on with that racing car!?"
Watching Amondero surpassing him at an increasingly faster speed, Hamilton shouted in the internal communication.
It was only then that people in the surrounding stands reacted;
Originally, no one had much hope for this practice session. Just like any F1 practice session in the past, most of the audience came to take photos with the racing drivers and then left to do whatever they were supposed to do. .
Because in practice matches, there generally won’t be too intense and sustained competition.
But at the beginning of this game, there was such an explosive scene that made the audience excited!
What excites them even more is that Hamilton, who has won three consecutive F1 championships, actually lost in a secret battle with Amondero, a pure rookie!
For a time, shouts like a mountain roar and a tsunami echoed throughout the stadium, and many spectators threw their popcorn into the sky.
"Lewis, don't be in a hurry. Keep up, their engine is brand new, and now it seems that the acceleration performance and explosive power are very good, but such an engine may not last the entire game. Follow him, get close to him, and provoke him , we must force that rookie to use his full strength and see the full performance of their engine!”
"As you wish!"
After receiving the team message from the technical director, Hamilton directly shifted up and continued to increase the speed.
The acceleration section of the Copse corner is not long. The driver can shift the car to 6th gear in this section, which is about 270km/h. But this interval was too short. After just completing the overtaking and leading two car bodies, Amondero came to Maggots, Becketts and Chapel, three consecutive corners.
Following the normal procedure, he adjusted the speed of the car to 272km/h in fifth gear to enter the corner, then dropped it to 160km/h in 4th gear, and prepared to exit the corner in 5th gear at 248km/h.
This can maintain speed to the greatest extent and ensure that the tires do not lock when entering corners.
However, just when he entered the second consecutive corner, he was surprised to find that the distance he had just opened before entering the corner had been completely made up by Hamilton through his skills!
It must be said that Hamilton is a very comprehensive driver who dares to fight at any time. He recovered the disadvantage through a corner and stayed close behind Amondero's car. Spotting Amondero's seemingly average but actually quite flawed cornering skills, Hamilton used a trick of delayed braking to directly accelerate and absorb the wake of the car in front, using the Mercedes-Benz Michelin tires to outperform Williams in cornering performance. The excellent characteristics of Bridgestone tires completed a smooth overtaking maneuver, directly turning the lagging behind into parallel and slightly ahead of the car.
He entered the third corner with a front-end advantage. When entering the corner, he further adjusted at a small angle to take advantage of the rules of the leading position, forcing Amondero to give way and completing a car body Perfect and beyond!
This set of operations made the audience in the surrounding auditorium stand up and burst into warm applause.
The commentator also shouted excitedly in his drake voice, "This overtaking is as standard as a textbook! It is really unimaginable that we will see this scene in a practice session that is enough to be included in the top ten best overtakings of the year!" ”
Even Li Fanyu and Alonso, who were sitting in the team's pit area, had to admit that Hamilton's series of technical processing just now was perfect.
In just half a lap at the beginning, two overtakings were completed, and the track became intense for a while. Hamilton also used two overtakes to fully prove his skills.
"Goodjob! Lewis."
Listening to the technical director's praise in the team communication, Hamilton glanced at the rearview mirror.
He found that Almondro was also looking at him through the rearview mirror. Looking into those blue eyes, Hamilton smiled coldly, with unspeakable contempt.
At this time, the cars had entered the HANGAR straight, the longest and fastest section of the Silverstone circuit, one after the other!
Just when Hamilton quickly increased his speed and prepared to further establish his advantage, he heard a strange cry from behind him... like a mechanical demon!
