What do the T4 or T6 stickers on the back of Volvo vehicles mean

2018-05-08 12:48:46

The "T" in the rear T4 or T6 of Volvo vehicles refers to turbocharging technology, and the number behind represents the power of the engine, the larger the number, the stronger the power parameters. 1, Volvo 2.0T model, T4 refers to the car equipped with the engine is B4164T, 2, the new Volvo XC90 all use a 4-cylinder engine, but because of the configuration of turbocharged plus supercharged, so it is named "T6". 3, the tail mark can distinguish the horsepower of Volvo models, for example: T4 refers to the engine power of 150 ~ 200 horsepower, T5 is 200 ~ 250 horsepower, T6 is 250 ~ 300 horsepower. 4, the first in this series of array of engines B refers to the gasoline engine, that is, the engine uses gasoline as fuel or diesel or other, and B refers to the gasoline fuel engine. The second refers to the number of cylinders, four is four cylinders, five is five cylinders. The third and fourth places refer to the displacement of the engine. 16 refers to 1.6 emissions and 20 refers to 2.0 emissions. The fifth T is for turbocharging. The last number refers to the special mark given by the engine manufacturer. 1. TSI: In TSI, T (Twinscharger) refers to double supercharging (turbocharged + supercharged), S (Stratified) refers to stratification, and I (Injection) refers to injection. In a strict sense, TSI technology is a combination of dual pressurization and layered direct injection technology, but the technical requirements are very high. In 2005 Volkswagen first introduced a 1.4L TSI engine system. Volkswagen's TSI technology represents a different meaning outside, foreign cars with the TSI logo indicate that it is equipped with dual supercharged (turbocharged + supercharged) fuel stratified direct injection motor, with high power, high torque, low speed characteristics; In the TSI often represents only turbocharged engines, its power and economy are better than the same displacement of naturally aspirated engines, and mechanical supercharging is not reflected in the engine. 2. TFSI: T stands for turbocharging, and FSI (Fuel Stratified Injection) is a fuel stratified injection technology, so TFSI can be said to be a combination of the two. It's similar to Volkswagen's TSI, which is what half of Audi's models are called. 3, Hybrid: Hybrid models are generally referred to as HEV, the car is marked with hybrid, meaning that it is equipped with two power sources at the same time, traditional fuel engine and electric power supply. Now, under the influence of national policies, hybrid vehicles have been rapidly developed. The advantage of hybrid vehicles is that they can be flexibly regulated according to different working conditions, which not only protects the environment but also reduces fuel consumption. 4. DM: DM is short for Dual Mode. It is a technology that combines pure electric vehicles (EV) and hybrid electric vehicles (HEV). DM dual-mode electric vehicles, as the name suggests, are vehicles with both pure electric and hybrid modes. This technology can combine the engine and the electric motor to realize a variety of energy supplement methods that can be charged and refueled. The technology is used in many of BYD's models. 5, VVT, CVVT, DVVT, etc. : These are called variable timing valve technology, the basic principle is small, in order to highlight the high-end, the name of each brand is different. Such as Honda's VTEC, i-VTEC, Toyota's VT-I; Nissan's CVVT; Mitsubishi's MIVEC; Suzuki VVT; S-VT from Mazda, VVT from JAC and Great Wall. 6, 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 big, but AWD in the wet road, bad weather and slight off-road road can provide better traction, BMW's xDrive, Mercedes-Benz's sDrive is actually a full-time drive system, the name is different. Quattro is the full-time drive system of Audi, Audi is the first to use four-wheel drive device in the great success of the car, and the mention of Audi Quattro will recall the Torsen differential, which is the core of the Quattro system. This system ensures that even if all three wheels of the car miss the ground, 100% of the power will be transferred to the wheels that have not lost the grip.
