Inventory: the meaning of the car tail logo, the engine's secret is here

It can be said that the front face of the car is the face of the entire car. Friends who are familiar with the car can recognize the car by looking at the face of the car. Therefore, many car companies are now emphasizing the family-style design. The front face looks at the value of the face, and the tail can only look at the connotation. Now, I believe we all notice that there are always several English letters on the rear of the car. Here are all the important parameters of the car. In general, the tail logo has a variety of engine technologies and drivers in addition to the model and engine displacement. The code name of the system is often seen but it cannot be remembered. Let's take a look.

TSI

TSI (Twinscharger) refers to dual boost (turbocharged + supercharged), S (Stratified) refers to stratification, I (Injection) refers to the injection. Strictly speaking, TSI technology is a combined application technology of double booster and layered direct technology, but it has high technical requirements.

Speaking of TSI, we must mention the Volkswagen Company. In 2005, the Volkswagen was first equipped with a 1.4L TSI engine system, and now most of the Volkswagen models have the TSI logo. However, according to Xiaobian, the meaning of VW's TSI technology is not the same at home and abroad. The foreign TSI logo indicates that it is equipped with a double boost (turbocharged + supercharged) fuel layered direct injection. The engine has the characteristics of large power, large torque, and low speed; in China, TSI often represents only turbocharged engines, and its power and economy are better than those of naturally aspirated engines with the same displacement, but supercharging is not reflected in the In the engine.

TFSI

T stands for turbocharging, FSI (Fuel Stratified Injection) is fuel stratified injection technology, so TFSI can be said to be a combination of the two. It is similar to Volkswagen's TSI in China. Half of Audi's models will be called this way.

Hybrid

The hybrid model is generally abbreviated as HEV. After the vehicle is marked with Hybrid, it means that it is equipped with two kinds of power sources, a traditional fuel engine and a power supply. With the impact of national policies, hybrid vehicles have developed rapidly. One of the advantages of hybrid power is that it can be flexibly adjusted according to different working conditions, which not only protects the environment but also reduces fuel consumption.

DM

DM is an abbreviation for Dual Mode. It is a combination of pure electric vehicle (EV) and hybrid (HEV) technology. DM dual-mode electric car as its name suggests is a pure electric and hybrid mode coexisting car. This technology can be used in combination with an engine and an electric motor to achieve a variety of energy supplements that can be charged and refueled. Many of BYD's models use this technology.

VVT, CVVT, DVVT, etc.

These are called variable timing valve technologies and the basic principles are similar. To highlight the high-end, the names of various brands are different. Such as Honda's VTEC, i-VTEC,; Toyota's VVT-i; Nissan's CVVT; Mitsubishi's MIVEC; Suzuki's VVT; Mazda's S-VT, JAC and Great Wall's VVT.

Quattro, 4WD, AWD, xDrive, sDrive

4WD is a four-wheel drive system, AWD is a full-time four-wheel drive system, the difference between the two is not, but AWD can provide better traction ability on wet roads, bad weather and light off-road, BMW xDrive, Mercedes-Benz sDrive Actually, it is a full-time drive system and it is called differently.

Quattro is Audi's full-time drive system, Audi is the first to use four-wheel drive device in the rally for great success, and mention Audi Audi Quattro will think of Torsen differential, which is the core of the Quattro system, this system can To ensure that even if the three wheels do not grip the car, 100% of the power will be transmitted to the wheels without losing their grip.
