The English letters on the car stand for the following meanings respectively:
1. TSI
Volkswagen's TSI has different meanings at home and abroad. The foreign meaning is TwinchargerStratifiedion, which refers to the dual supercharged (turbo and mechanical supercharged) stratified injection technology. In China, T stands for turbocharging and Si stands for direct fuel injection, rather than the abbreviation of T and FSI. There is no stratified fuel injection technology, because the domestic fuel quality is average and it cannot meet the requirements of stratified fuel injection.
second, TDI
TDI is the abbreviation of English TurboDirection, which means turbocharged direct injection diesel engine.
in order to solve the inherent deficiency of SDI (naturally aspirated diesel engine), people have installed a turbocharger on diesel engines, which greatly increases the intake pressure and the compression ratio is generally above 1.
in this way, a great torque can be achieved at a very low speed, and the content of harmful particles in the emissions is greatly reduced because of more complete combustion. TDI technology makes the fuel directly injected into the cylinder through a high-pressure injector, because the piston top shape is a concave bowl design, and the fuel will form a spiral mixture in the cylinder.
vvt/cvvt/vvt-I/mivec/vtec/I-vtec
vvt/cvvt/vvt-I/mivec/vtec/I-vtec stands for engine variable valve timing technology.
the principle of engine VariableValveTiming technology (VVT) is to adjust the intake (exhaust) quantity, valve opening and closing time and angle according to the running situation of the engine, so as to optimize the intake air quantity and improve the combustion efficiency. The advantage is fuel saving, and the power-to-lift ratio is large, while the disadvantage is insufficient speed and torque in the middle section.
at present, Honda's VTEC, I-vtec,; Toyota's vvt-I; Nissan's CVVT；; MIVEC； of Mitsubishi; Suzuki's VVT；; Modern VVT；; Kia's CVVT；; VVT； of jianghuai; The VVT of the Great Wall has gradually begun to be used. Generally speaking, it is actually a kind of technology with different names.
IV. Hybrid
Hybrid stands for hybrid power.
a HybridElectricalVehicle (HEV for short) refers to an automobile equipped with two power sources at the same time-a thermal power source (produced by a traditional gasoline engine or diesel engine) and an electric power source (battery and motor).
v. Quattro
Quattro stands for full-time four-wheel drive.
the core of p>Quattro full-time four-wheel drive is Torsen central differential, which can adjust the distribution of front and rear axle forces faster than any electronic control technology. EDL (electronic differential system) transmits the extra power to the wheels when necessary to enhance the grip.
Extended information
The meaning of the English letters of the gear of the automatic automobile gearbox
P: parking gear, starting gear. When you stop, the gear is here. At this time, the wheels are locked mechanically, which can prevent them from slipping.
R: reverse gear. When reversing gear, as the name implies, when reversing this gear.
N: neutral. Use this gear when parking temporarily.
D: forward gear, driving gear. In this gear, the gearbox will automatically switch between gear 1 and gear 5 according to the speed and throttle.
S: Sport mode. When engaged in this gear, the gear can be switched freely, but the shift timing is delayed, so that the engine can maintain a high speed for a period of time, which increases the power of the car. However, this gear will increase fuel consumption.
L: low gear. In this gear, the gearbox will remain in the first gear without upshifting, which can be used on ramps and other situations. It also has a certain braking function when going downhill.

people's network-pay attention to these points, it is not a problem to drive an automatic car.
