The current 1.4T is undoubtedly very important to the public, from golf, Langyi, to Passat, Maiten and even The Audi A3, etc., it can be seen.
EA211 1.4T engine
The EA211 1.4TSI engine was put into operation at the FAW-Volkswagen Changchun plant in August 2013, and the first model to be equipped with it was the domestically produced Seventh Generation Golf. Today, the EA211 1.4TSI engine has been "in service" for nearly 9 years, but its "TSI + DSG" golden power combination with the DSG transmission can still be played today.
Of course, it can be played, but in the face of today's white-hot market competitiveness, this set of 1.4T + DSG gold powertrain, whether it is actual data or power experience, has long been not the style of the year. In the era of 2022, when competitors are emerging, it is obvious that there are still missing highlights.
In fact, Volkswagen has long thought of this problem, as early as 2017 Volkswagen launched a new EA211 1.5T EVO engine, overseas, many models have long been used, but it has not been introduced into The country. It is also for this reason that when the new Golf, A3 and other companies are listed, they are still criticized for "why the new car is not on the latest 1.5T engine".
Although I don't know why Volkswagen has delayed the introduction of this machine, from the declaration information of the previous mid-term revamp sagittarius, the new 1.5T engine is finally coming. The mid-term redesign of Sagitar has become the first new car in China equipped with a new 1.5T engine.
Let's not talk about some new changes in the mid-term modification of Sagitar, and today we will mainly talk about this high-profile 1.5T engine.
Although this 1.5T engine Shanshan is late, but compared with the version released in 2017, the cash given to the domestic has evolved to the second generation, which can also be regarded as a compensation for domestic consumers, after all, the brother is also waiting for this machine to wait for the eyes to wear. To be honest, if the A3 had been equipped with the latest 1.5T engine, I might have been the owner of the Audi A3 by now.
So, where is the progress of the second generation 1.5T compared to the first generation?
In fact, the first generation of 1.5T has two kinds of power, high and low power, the low power version pays more attention to efficiency, and the high power version emphasizes more power. However, the second generation of 1.5T can be said to combine all the advantages of the first generation of 1.5T high and low power. While it has 10 horsepower more power than the first-generation 1.5T high-power version, the compression ratio is also higher. Simple understanding, it can be said that the power is stronger and more fuel-efficient.
So what if compared to the 1.4T engine currently on sale?
Looking at the parameters alone, the progress is not obvious. To tell the truth, although Volkswagen's current 1.4T engine has been available for many years, it has been 8 years since its fingers were pinched, which is slightly old from the year, but it is not bad in terms of power and fuel consumption performance. The current 1.4T has a maximum of 150 hp and 250 Nm, while the new 1.5T has a maximum of 160 hp and 250 Nm. The horsepower has only increased by 10 horses, and the torque is the same. The maximum horsepower increase is not much, which means that the acceleration capacity and cash performance will be similar.
Of course, although there is not much improvement in paper parameters, if you look at it from the technical dimension, this 1.5T is equipped with a lot of new technology. For example, variable-section turbines, 350 Bar high-pressure injection, APS coating technology, electronically controlled cooling systems, etc., also achieve a thermal efficiency of 37.5%. The application of a series of new technologies is mainly to reduce fuel consumption and improve the response speed at low speeds.
Among them, the variable section turbine used in the new 1.5T is a major highlight, the principle is not much to say, from the result, this turbine can greatly improve the response speed and acceleration ability of the engine at low speed. Friends who have driven the current 1.4T version of the model should have this feeling, that is, the turbine lag of this machine is more obvious, the floor oil is down, the gearbox has completed the downshift, but the power still has to wait for about 1 second to emerge, which is slightly discounted on the driving experience.
If the power response speed is improved, then even if the account parameters are not much improved, the improvement in driving experience is real. Brother Understand often expounds a point of view: daily driving, power and feet in many cases are more important than the absolute power value. This is why in fact, many Mazda cars, the parameters look mediocre, but when you start to use, you feel that this car is particularly easy to drive, especially easy to get started, because the power output is particularly heeled, and the power output is in line with expectations.
Write to the end
The EA211 1.5TSI engine, especially the latest EVO2, is one of the most technologically advanced engines available today. However, the traditional internal combustion engine has been developed for so many years, the potential has been almost tapped, no matter how advanced, fuel consumption and power are difficult to have a big breakthrough.
Here please allow you to sigh that the era of the traditional internal combustion engine is really coming to an end. At this stage, hybrid and pure electricity is the main focus of manufacturers, continue to develop pure internal combustion engine for manufacturers is really of little significance, car companies to launch new engines are less and less likely.
Coupled with increasingly stringent emission regulations, we can buy only a few pure internal combustion new cars in the future, and buy and cherish it friends.
