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. The tail can be seen at the end It is believed that everyone notices that there are always several English alphabets on the rear of the car. Here, all of them show important parameters of the car. In general, the rear logo has various engine technologies and drivers in addition to the model and engine displacement. The code number of the system, some of them are often seen, but it can't remember its meaning. Let's take a look.
TSI
TSI T (Twinscharger) refers to dual boost (turbocharged + supercharged), S (Stratified) refers to stratification, I (Injection) refers to the injection. Strictly speaking TSI technology is double booster and stratified direct technology The integrated application technology, but the technical requirements are high.
Speaking of TSI, we must mention the Volkswagen Company. In 2005, the Volkswagen was first equipped with a 1.4LTSI engine system. Now most of the Volkswagen models have the TSI logo. However, according to Xiaobian, the public's TSI The meaning of technology represented at home and abroad is different. The foreign TSI logo indicates that it is equipped with a dual turbocharged (turbocharged + supercharged) fuel stratified direct-injection engine with high power and large torque. Low speed characteristics; In China, TSI often only represents turbocharged engines, its power and economy are better than the same suction naturally aspirated engine, and supercharging is not reflected in the engine.
TFSI
T stands for turbocharging, FSI (FuelStratified Injection) is a 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, and half of Audi's models will be called.
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 at the same time. The traditional fuel engine and electric power source. Now the impact of national policies, hybrid vehicles have been rapidly developed, and hybrid power is relatively high. The advantage is that it can be flexibly controlled according to different conditions, which not only protects the environment but also reduces fuel consumption.
DM
DM is the abbreviation for DualMode. It is a combination of pure electric vehicle (EV) and hybrid (HEV) technology. DM dual-mode electric car is the name suggests is a pure electric and hybrid mode coexisting car. This technology can combine the engine and the motor Take advantage of this to achieve a variety of energy supplements that can be recharged and refueled. Many BYD models use this technology.
VVT, CVVT, DVVT, etc.
These are called variable timing valve technologies and their 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
The 4WD is a four-wheel drive system, and the AWD is a full-time four-wheel drive system. The difference between the two is not significant. The only difference is that the AWD is on wet roads, and bad weather and light off-road pavement can provide better traction. BMW's xDrive, Mercedes-Benz sDrive Actually it is also a full-time drive system.
Quattro is Audi's full-time drive system. Audi is the first car manufacturer to use four-wheel drive in the rally. It will be remembered by Audi's Quattro. This is the core of the Quattro system. To ensure that even if the three wheels are not gripped, the car will deliver 100% of its power to the wheels without losing its grip.
