A few days ago, CAR Brother learned from the 353rd batch of "Road Motor Vehicle Manufacturers and Product Announcements" new product announcement issued by the Ministry of Industry and Information Technology that there are several newly declared models in addition to minor changes in appearance, but also replaced the power system, from a 3-cylinder turbo engine to a 4-cylinder engine.
The timeline returns to 2012, when Ford launched the 1.0L Ecoboost three-cylinder turbocharged engine, which won international awards including Ward's top ten engines for many times, and later swept a 3-cylinder engine research and development boom in the automotive circle.
Of course, a simple engine can not bring up the 3-cylinder boom, and there are emission policy reasons, Europe as the birthplace of many traditional cars, the government requires car companies to reduce the average fuel consumption to 4.2L/100km in 2020, and the average fuel consumption to 3.4L/100km in 2025.
For reducing fuel consumption, there are currently two routes, one is a small displacement supercharged engine to replace a large displacement self-priming engine, and the other is the use of hybrid technology. Among them, the small displacement supercharged engine also derives two branches of intelligent closed cylinder and cylinder reduction, intelligent closed cylinder is similar to the current GM Group widely used 2.0T engine, can intelligently close the twin cylinder when the engine is running at low load, to achieve the purpose of emission reduction.
The reduced cylinder is well understood, V6 is changed to L4, L4 is changed to L3. Take the protagonist of this article, the L3 in-line 3-cylinder engine, that is, three identical single cylinders arranged on a cylinder block, sharing a crankshaft output. Due to the lack of a cylinder, the volume is smaller, the weight is lighter, and the fuel consumption control can also be effectively reduced.
In addition, Ford's 1.0T three-cylinder turbo engine is effective enough to suppress engine resonance with engine components such as double balance shafts and dual mass flywheels, so the fuel consumption is excellent and stable, and it is also handy to win many world-class engine awards such as Ward's top ten.
This makes many car companies see hope, BMW launched the famous B38 series 1.5T three-cylinder turbo engine, like the more than 2 million BMW i8 is the use of the model B38K15A 1.5T three-cylinder twin turbo engine and drive motor composition. Like the current domestic BMW 1 Series, 2 Series, X1, imported 2 Series, Mini and many other BMW Group models equipped with 1.5T are three-cylinder engines.
PSA Group's 1.2T three-cylinder turbocharged engine, Ford Motor's 1.5T three-cylinder turbo engine, General 1.3T three-cylinder turbo engine, and Honda's 1.0T three-cylinder turbocharged engine have also been launched, and have been installed in some domestic models. Of course, among the independent brands, there are also manufacturers with strong R&D strength for the development and application of 3-cylinder engines, such as the 1.0T three-cylinder turbocharged engine launched by Geely Automobile.
From the market side of the sales and netizens' evaluations reflect that everyone's awareness of the 3-cylinder engine is higher, but the recognition is relatively low, after all, the 3-cylinder engine is born in terms of jitter inhibition is not as good as the 4-cylinder engine, most of the engine jitter can be absorbed by the balance block, rubber parts, etc., but the rubber parts age faster, especially bmw's rubber, not very durable.
At present, bmw brand products only entry-level 1 series, 2 series, X1, X2 and other parts of the model will be equipped with B48 series 3-cylinder engine, the previous low-end use of 1.5T three-cylinder engine BMW 3 series after the replacement of the successful fading of the three-cylinder luxury mid-level car title.
Originally in the Chinese car market for the wind and rain Ford Focus and Buick Yinglang, but also the use of 3-cylinder engine after the folding, Fox insisted for many years, and finally in the latest batch of declaration information showed that it will be equipped with the same series of 1.5T four-cylinder turbo engine as the Wing Tiger, becoming the world's only 4-cylinder engine in addition to the Focus ST, RS performance version, the world's only 4-cylinder engine equipped with a 4-cylinder engine of The fork forks still provide sports hatchbacks and practical sedan models.
Although it has changed, the market is no longer yesterday's market, but has become a car market dominated by comfort and space such as Langyi Xuanyi Corolla, and even Sagittarius has not been able to launch a long wheelbase version on the basis of not giving up sports control. With the Same Fawkes as sporty-controlled Mazda 3, it sells more than 80,000 units a year and golf more than 60,000 units a year, leaving really little space for Fox.
Coincidentally, there are two models in the independent brand declaration list that use the same method as Fox, abandoning the 3-cylinder engine that insists on the same and using a 4-cylinder engine instead, that is, Geely ICON and the redesign of Binyue and Binrui.
From the original 1.0T three-cylinder turbocharged engine to the new Raytheon power series of 1.5T four-cylinder turbocharged engine, the new engine in addition to more stable cylinder structure, will also have a stronger output in terms of power and torque.
Of course, the most powerful "overturned" in the 3-cylinder is not the above model, but the Nissan X-Trail, which has good sales and reputation. Under the strong brainwashing recommendation of "too fun", he is still powerless to return to heaven, and even wakes up the discontinued old Qijun, and the plot is comparable to the online novel of the real fantasy genre of the heavy life cultivation.
Because most consumers are sharing the "three cylinders" discoloration, the sales of new cars are not high, and the second-hand recycling price is not ideal, resulting in a dead cycle to a certain extent. The only special case is the BMW series of products, from the BMW X1 point of view, more users for the large space and blue sky and white cloud aura to choose the entry of the 1.5T model, and the second-hand market price is also relatively firm, because it has a market.
Whether it is a torque beam, a double-clutch transmission or a three-cylinder engine, for consumers, it still requires a long adaptation time, especially in today's society with developed networks, a plate suspension, a big setback, and obvious shaking can make the car company's years of research and development efforts in vain. As everyone knows, the torque beam adjustment of some car companies has a better dynamic performance than some multi-link models, and the fit between the self-developed and matched dual-clutch transmission and the engine is also stronger than Aisin 6AT and 8AT, but the 3-cylinder engine, still insisting on it is not much, and the new technology can not play it?
