Introduction | is all about saving fuel
Ten years ago, a leader said that the last technical barrier of independent brands was automatic transmission, and then Great Wall and Geely's DCTs were made. Three years ago, an industry senior said that the biggest shortcoming of independent brands is fuel consumption, so great wall and geely have come out of DHT.
Slightly different, the Great Wall DHT's T is Technology, and Geely's T is Transfer, indicating that this set of Thor-powered transmission mechanism is the core.
After all, Geely's Thunder God Has three gears.
▲Zhejiang Yiwu test drive Star Yue L Thor hybrid version
It is about 10 minutes long and is recommended to watch under Wi-Fi
Recently, Che Jujun and his party came to Yiwu, Zhejiang Province, and visited the Leishen Power Plant, which mainly produced this SET OFHT Pro three-stop mechanism, and then sent it to the black light factory in Xi'an, and then assembled into the Thor Hybrid Version of Xingyue L.
1 fuel car like an electric car
The front face of the new car has changed, from the "energy string" of the 4.0 era to a dot-matrix semi-enclosed design to distinguish the fuel version from the hybrid version. Apart from that, the exterior and interior have hardly changed. The manufacturer confessed that it could not shoot the interior details, saying that it was not yet a mass production version. Is there a big difference?
Friends who are interested in the interior can review "20 Minutes of Raw Shooting: Is Hoshigoku L Really the Ceiling of 150,000 SUVs?" 》。
The license plate of the Hoshigoku L Thor Hybrid Edition is marked Hi · X, Chinese called Ray, is equipped with DHT Pro technology unveiled at The Night of Gilly Dragon Bay on October 31, 2021. It is also the first time that Geely has used it on Xingyue L, because the "star" character is the most high-end series under the Geely brand, called China Star.
Ray's Mind Hi · X hybrid system, can match different models of A0-C class, adapt to HEV, PHEV, REEV and other full hybrid systems, full power domain can BETA upgrade, up to 20 intelligent driving modes, 148 NVH technology optimization...
Okay, this thunder god does sound like a god.
Of course, this time the main test fuel consumption: the way to the end is the energy saving race, the main test of the minimum fuel consumption is what? The return trip is a free test drive, can you measure what the actual fuel consumption is?
This Hoshikoshi L equipped with a 3-speed hybrid electric drive DHT Pro, NEDC fuel consumption is 4.3L, how did this happen?
It can be EV motor driven, extended range motor drive, hybrid oil and electricity, engine power generation + auxiliary drive, and finally get rid of pure engine drive and become an electric vehicle without charging.
Simply put, it is paralleled in the full speed domain, and can be electrical, oilable, and extendable.
It and the ideal ONE both use a 55L fuel tank, but the biggest difference is: the ideal ONE requires an external power supply to charge the 40-degree battery, and the Hoshikoshi L Raytheon hybrid can realize the motor self-charging. In this way, the ideal ONE has a range of 1080km, while its NEDC has a range of up to 1300km.
Someone calculated that the energy cost of opening the ideal ONE one kilometer is 4 cents, and the star-more L hybrid is 3 cents.
The province returns to the province, and its power is not bad: the acceleration of 100 kilometers is 7.9 seconds, which is much faster than the 9 seconds of the Japanese equivalent hybrid. In particular, the acceleration of 80-120km is 30% faster.
Hoshigoku L Thor hybrid engine is a hybrid-specific DH15.
Yes, it is a 1.5T three-cylinder machine, it is estimated that many readers can not pass the heart of this hurdle; for example, Yinglang previously equipped with a three-cylinder engine, and finally forced to change back to a four-cylinder engine due to sales pressure. So where does Auspicious's confidence come from?
It has been optimized, such as 350Bar high-pressure direct injection, in-cylinder boosting, low-pressure EGR, and Miller cycle. Some parts have also been improved, and the final thermal efficiency can reach 43.32%, which is currently the first thermal efficiency of mass-produced vehicles in the world.
Paired with this is the 3-speed hybrid electric drive DHT Pro.
Under a gearbox housing, it is installed sequentially: P2 motor, transmission structure, P1 motor. Both motors can be used as generators and drive motors, the difference is that the P1 motor power in the back is relatively small, and the probability of doing the generator is greater, which is equivalent to the extended range motor; while the front P2 motor is more as a drive motor, equivalent to an EV motor.
The division of labor is clear, each performs its own duties, and it is seamless.
The advertising is done well, and it depends on the efficacy. We went 50 kilometers away, including congested sections of the city, expressways and mountain roads, and the final fuel consumption showed 4.0L.
But be sure to pay attention to the opening method of the energy-saving race, the whole process as far as possible to use smooth low and medium speed, but also turn off the large screen, of course, not below the minimum speed limit.
Although Che Jujun used the "golden right foot" along the way, combined with the experience of driving an electric car, the average speed of the whole process was 33km/h, but it still did not win the first place. The reason is that his fuel saving range is 60-80km/h, which is exactly the opposite of trams, not that the slower the speed, the more fuel-efficient.
In a word: Although the overall driving sense of the Hoshikoshi L hybrid version is very similar to that of electric vehicles, his soul is still a fuel vehicle, and the advantage is in the middle and high-speed range, don't pity it!
Therefore, on the way back, we turned on the air conditioner, sang songs, and drove all the way, and the fuel consumption shown at the end was 6.0L, which was 2 liters more than the energy-saving race, which was still better than we expected.
Therefore, this test is equivalent to giving us two boundaries: the extremely fuel-efficient opening, which can be as low as 4L; the dashing and vigorous opening, that is, about 6L.
It can be compared to the Japanese system, and the predecessor can rest assured.
More comparable to the Japanese is its NVH. When the vehicle was driving at a speed of 80 kilometers per hour, the inside of the car was only a little dry tire, very quiet, and we did not need radio equipment to shoot videos in the car. Officials say that 148 mute technologies are used, and the noise in the car is 4-5 decibels lower than that of the Japanese counterpart.
Q. How is this level of sound insulation for the assistant? After 95, he asked: Is the sound insulation of Japanese cars very good?
2 Behind the finesse
DHT Pro is easy to use, inseparable from Yiwu's "Thor Power" smart factory.
Similar to the "Black Light Factory" in Xi'an, this is an ultra-modern factory.
The biggest impression of entering the factory is that it is clean, tidy, quiet, and there is not even a trace of odor. When we entered the workshop, in addition to wearing shoe covers, dust-free clothes, and hats, we had to go through a wind tunnel. Finally, "fully armed" can enter, which shows that the requirements for dust-free are very high.
Because, this is a "micro factory".
Micron means high precision. The diameter of a hair is about 60 microns. The error accuracy of the Yiwu micron factory on the parts is only a few microns.
It is mainly divided into two categories: tooth shaft class and shell type. First of all, the processing process of the tooth shaft, in order to ensure the accuracy of the gear ring, it is necessary to go through three processes: pre-heat, hot-in and post-heat. Among them, there is a very important process called spline before heating, so that its accuracy does not exceed 3 microns, and this whole process can be completed to reach the standard of microns.
This is not the end, but also through a rolling honing compounding machine for the next round of treatment, it is said that this is the only machine in Asia, geely spent tens of millions of dollars imported from abroad. Its role is to polish the hot-formed parts again so that the accuracy of the surface texture cannot be greater than 2 microns.
Finally, there is the most stringent workshop, the valve body workshop. In order to ensure precision, no one except the staff can enter, not only is the temperature and humidity constant, but even 99.9% of the particles in the air with a diameter greater than 0.3 microns will be filtered out.
What is this concept, also refer to the N95 mask can filter 95% of particles greater than or equal to 3 microns in diameter. It is conceivable how strict the dust-free is, and it is precisely because of such a system that its DHT Pro three-speed hybrid electric drive mechanism can be made more professional.
Car gathering summary
The measured fuel consumption of 4-6L was unimaginable a few years ago, and the last dividend of the Japanese system seems to be disappearing.
No wonder Hoshikoshi L Hi · As soon as the X Hybrid version opened pre-sale, the 2022 new cars were snatched up. Geely said happily that in the next 3 years, this technology will be successively launched into more than 20 new models under the Geely and Lynk & Co brands. Moreover, it is not excluded to lend to other high-end brands and export to the European market.
