The country has also tried many methods, whether it is market for technology or reverse development, the effect is not great. Because the internal combustion engine is too complicated, it involves both technology and experience accumulation, and the technical level is also essential. At the same time, the internal combustion engine is very fragile, and if you don't pay attention to it, all kinds of problems will occur, with a slight difference.
Later, the country also "figured it out." Starting from 20 12, we mainly subsidized new energy vehicles and tried to overtake in corners. Unexpectedly, a bunch of "cheating" little experts were born, creating a lot of "industrial waste". However, the traditional internal combustion engine suddenly became "enlightened". In recent years, it has flourished, and major mainstream independent brand car companies have their own reliable fist products.
Among the top ten engines of "China Heart" in 2020, there are eight self-owned brands on the list, and of course there are two heads of Honda and General Motors. What about these ten engines? What kind of past lives did they have? Let Che Jujun take everyone to have a look.
First, the red flag 1.5T is the key to rejuvenation.
Hongqi's sales volume has increased by leaps and bounds in the last two years. In the past month of 65438+ 10, 23,000 vehicles were sold, an increase of 93% over last year. The revival of the Red Flag mainly benefited from the "two carriages" of H5 and HS5. After all, there are still a few C-class cars like H9 at any time.
This year, Hongqi H5 is equipped with a brand-new 1.5T assembly, which is the award-winning one. The maximum power of this engine is 124kW and the maximum torque is 258N? M, it's not too brilliant in terms of parameters. The 1.5T four-cylinder model close to the power level has been on the Great Wall for several years. Moreover, this engine has to "drink" No.95 gasoline, which is more expensive.
However, compared with the 20 19 1.8T engine, the fuel consumption of this 1.5T engine is reduced by nearly 1L/ 100km under the same power, and the acceleration performance is even better. So its appearance solved the urgent need of the red flag. From this perspective, its market significance is very great. I believe that there is a certain recognition significance in awarding this award to the engine of Hongqi.
Second, Ke Ling 1.5T light mixing has low cost and great effect.
Compared with other car companies, Geely is simply a "playboy" who wants to get involved in everything. Self-priming, turbo, four-cylinder machine, three-cylinder machine, CVT, AT, dual clutch, almost all can play. Anyway, there are three major brands below, and there is nothing wrong with trying them all.
In terms of mixing, Geely can also be called "half-hearted". It was initially reported that Geely will cooperate with Toyota to "receive" Toyota's THS technology through its holding company Yuan Keli. Then it was passed on for a long time, and there was no more. Ke Ling 0 1 actually launched an HEV model, but it adopted its own original architecture, and then it didn't focus on promotion. Many PHEV models have also been introduced, but none seem to be the main force.
Until more than a year ago, Geely seemed to set a goal at once, that is, to promote the 48V light mixing system. This system is very simple. On the basis of Geely 1.5T three-cylinder engine, a 48V BSG motor is added. When starting, the motor is used to improve the starting performance of the fuel engine, which solves the problem of idle fuel consumption of the internal combustion engine by the way. Then, step in when taxiing, save some oil, and help push when accelerating rapidly.
Although this system is simple, the effect of improving fuel consumption is very obvious, such as? Link 06? The comprehensive fuel consumption of MHEV models is 5.9L/ 100km, while that of the regular version is 6.6L/ 100km, which reduces the fuel consumption by nearly 1 1%, and improves the driving experience to some extent, so Geely is actively promoting this system now.
Third, Dongfeng 1.5T is finally no longer a "world card"?
Compared with FAW's "target of public criticism", Dongfeng's public opinion pressure as the "second brother" is much smaller than that of the great big brother.
But this does not mean that Dongfeng is doing well. Compared with FAW's Pentium and Hongqi, Dongfeng's independent technology is weaker. Several models of "dear son" Dongfeng Shen Feng have used imported engines and gearboxes for a long time. Fortunately, Dongfeng is closely related to PSA, Nissan and Honda, and has a joint venture with Getrag, but it has been able to churn out different models.
Dongfeng 1.5T engine has not been launched for a long time, with maximum power 1 10kW and maximum torque of 230N? M, compared with Great Wall Geely, is basically the level of the previous generation. It is true that the fuel consumption and power performance of AX7 are not brilliant, but independent research and development is always a good thing.
Not long ago, Dongfeng announced that it would launch a new generation of high-performance supercharged direct injection gasoline engine, code-named C 15TDR, which is divided into power version and high-efficiency version. The maximum power of the power version reaches 150kW, and the thermal efficiency of the high-efficiency version reaches 4 1.7%, which is much better than winning in terms of parameters. However, it remains to be seen how the specific strength is, when it can "get on the bus" and how the market will perform after "getting on the bus".
Fourth, Xiaoyun Power 1.5T, BYD's ambition.
In recent years, BYD's energy has basically focused on new energy vehicles. In fact, many people forget that at the beginning of the century, BYD and Chery were the top two self-owned brand car companies in terms of sales volume, and Geely's "wealth" was behind them. Moreover, BYD has made great achievements in the field of fuel powertrain. The first domestic turbocharged engine and the first domestic dual clutch gearbox were introduced by BYD.
The latest Xiaoyun Power 1.5T is BYD's big move to "suppress". The maximum power reaches 136kW and the maximum torque reaches 288N? M, compared with the old model 1.5T, the improvement is very obvious.
It is equipped with Song Plus, and BYD has spent a lot of effort to build it. With the foundation of quasi-medium SUV, how to match H6 and CS75? Coupled with the market for compact SUVs, BYD is still ambitious in the fuel car market.
5.MG 1.5T, finally surpassing Civic?
20 17, 165438+ 10 month, MG 1.5T engine was installed in MG? No.6, the slogan at that time was to surpass Civic and become the benchmark of domestic sports cars. Of course, it can't be surpassed in fact, but the main attention and battlefield of independent brands are concentrated in the SUV market, launching MG? Such a sports car is quite brave.
Now a new generation of MG 1.5T engine is on the market, with maximum power 133kW and maximum torque of 285N? M. This engine adopts Honeywell high-flow turbine, and the electronic control turbine has a very early intervention time and a very fast response speed. The maximum torque can reach 1500rpm, and all core parameters are stronger than Civic L 15B8.
New generation MG? The measured acceleration time of 6 kilometers is 7.98 seconds, which is 8.48 seconds longer than Civic. From this dimension, the flag set in that year has finally come true. However, it is worth pointing out that the 1.5T engine on Civic is not the strongest state of Honda, and it has not been updated in recent years. Is the high-power version of this engine installed on the crown track, or is it better than MG 1.5T Hope MG? We can force Honda to come up with something better.
6. Blue Whale 1.5T, the platform benchmark of autonomous powertrain.
In the 20 19 "China Heart" Top Ten Engine Selection, Changan's 1.4T blue whale nose has been selected. The previous 2.0T was selected in the list of 17, and this year it was changed to 1.5t ... "One door, three heroes". Changan, the blue whale powertrain platform, is really overbearing.
Changan this engine can be said to carry a very wide range, the most famous nature is Changan CS75? In addition, this car has recently launched a fierce chase for Haval H6.
The engine has a maximum power of 13 1kW and a maximum torque of 265N? Rice, more than Song? And MG? 6' s engine is slightly weak, but considering that this engine has been launched for several years, this result is still very good. Similarly, the turbine intervened early, and the maximum torque can reach 1450rpm. The point is, CS75? For a car as big as Plus, the comprehensive fuel consumption of MIIT can reach 6.7L/ 100km. From this perspective, the strength of this engine is really magnificent.
Ford asked for this engine before, but in the end it was estimated that it was still embarrassing. In fact, it would be a good choice to match the winged tiger.
Seven, Honda 1.5L mixed, the position is wrong.
A while ago, Che Jujun told everyone about Honda's third-generation i-MMD system, which is very powerful. As a latecomer, it bypassed Toyota's patent barrier with a different idea from Toyota THS system and put forward its own unique solution.
The core idea of TOYOTA THS system is to use the engine core and motor as an aid to make the engine run in the high efficiency area as much as possible, so as to achieve the effect of fuel saving. The core idea of Honda i-MMD system is to take the motor as the core and the engine as the auxiliary, so that the motor can work as much as possible, so that the natural fuel consumption will be reduced when there are more power consumption conditions.
However, Honda has never promoted this system in A-class cars. Until this year, this system is still going on in Ling Pai and Yu Xiang. But to be honest, although these two cars are huge, they are actually Honda's domestic "special supply" models, rather than "positive printing" global models like Civic. The main responsibility is to take the cost-effective route, take the quantity, and the overall texture is not good.
In fact, the early Lingpai sold well, relying on the old model 1.8L and then replacing it with 1.0T three-cylinder engine, and the engine was no longer its selling point. Comparatively speaking, these two cars actually need 1.5L Earth Dream self-priming engine, which has enough power, low fuel consumption and less exaggerated price. Now mix 1.5L, and the entry price is close to1.4000. At this price, many people choose Civic directly, or buy a Corolla dual engine, and this system has little chance to play.
8. GM 2.0T is no longer an "oil tiger"
The GM 2.0T engine is mounted on many models, such as Cadillac. Yes, you are not mistaken. At present, Cadillac is equipped with this engine, and models such as Regal, LaCrosse, Angkewei and Angkewei are also equipped.
GM has recently slimmed down this engine twice, including reducing its power from fifth to sixth. Compared with the previous old model, the new version of the six-seat is reduced by 3kW, but only the power is reduced, and the torque is not reduced. The maximum power still reaches 174kW, which is not bad in this level.
This engine adopts a unique "variable cylinder" mode and mainly designs a set of three-stage sliding camshafts. When strong power is needed, the high-angle cam is used to increase the valve opening and air intake, and the engine works hard. When the force is not needed so much, the low-angle cam is used to reduce the air intake, and the engine begins to "passively work" to reduce fuel consumption; When cruising or taxiing, you only need to turn off cylinders 2 and 3 to become a two-cylinder engine, which can achieve the ultimate fuel-saving effect.
After using this engine, GM's comprehensive fuel consumption has dropped a lot. In fact, the three sets of power combinations, 1.5L+6AT, 1.5T/2.0T+9AT, which are commonly used, have good economy and stability, and at least found their own direction.
Nine, the Great Wall new 2.0T, did not "get on the bus"
Great Wall participated in the selection of GW4N20 engine. According to official information, it was used in the third generation Haval H6 and Haval Big Dog. In fact, the 2.0T versions of these two models have not been released yet, and only 1.5T is currently on sale.
However, it is no secret that the Great Wall Engine has been released long ago.
According to the official information of the Great Wall, the new 2.0T engine has a maximum power 180kW and a maximum torque of 385N? M, this data is not inferior to Honda and Volkswagen's high-tech 2.0T, and the thermal efficiency of its first production model has reached 38.3%, which can be said to be very leading in technology.
The new engine adopts a new generation of Miller cycle combustion model, and also introduces a dual-channel supercharger and a small inertia turbine, which is an advanced technical scheme at present. But actually, we still have to wait for "getting on the bus".
Is there any chance for X.SAIC π engine and diesel engine?
SAIC's engine named "SAIC π" is "heterogeneous" on the list. With the implementation of the sixth national congress. Many diesel models that are not rich enough have been stopped outside the door of National Sixth, but "SAIC π" is a fish that escapes the net. ?
The maximum power of this engine reaches 160kW, which is close to the level of mainstream 2.0T gasoline engine. The maximum torque reaches 480N? M. What is the concept of this number? The maximum torque of Honda Crown Road's 2.0T engine is only 370N? M, nearly 30% higher. Therefore, it is well-deserved to say that the diesel engine is "powerful".
Of course, the riding of diesel engines has not been very successful, mainly due to rough workmanship and poor driving experience. SAIC has prepared quite a few noise reduction measures for it, including the use of high-precision silent gears and generator decoupling shock absorbers. Judging from the output results, it is still good. Unfortunately, there are too few models, their influence is limited, and they have not yet formed a fixed reputation.
Jeju tubercle
There are many things that have never been sown in the garden. In the years when the country completely "ignored" fuel engines and always advocated "no burning", the technologies of major manufacturers have made breakthrough progress. In fact, the reason is very simple, namely Haval H6 and Changan CS75? In addition, these models sell so well that manufacturers really make money, and the market has always been the best catalyst.
In fact, the same is true for new energy vehicles. In the past two years, the battery life has been improved and the efficiency has been improved. It is the time when government subsidies began to decline. Give the market back to these car companies and be less biased. When the face is black and blue, it is the fastest time to make progress.
