Please tell me about the VVT i engine or the i VTEC, which is better

What is the difference between V and T of the engine Which is better?

Hello <>

As for the difference between the V and T types of the hair like a smile motive, in fact, it is mainly manifested in their structure and performance. Type V refers to the V-shaped arrangement of the engine's cylinders, while T-type refers to the T-shaped arrangement of the cylinders. Due to the compact size of the V-engine, it is more space-saving in comparison.

The structure of the T-type engine is more suitable for the arrangement of engine fuel supply, power generation and other components, relatively speaking, better performance can be obtained. However, it is worth noting that which one is better depends on the specific use environment, needs and other factors. In addition:

The arrangement of the engine is divided into a variety of ways, including in-line four-cylinder, V-type six-cylinder, etc. Among them, V-type and T-type engines have been widely used in slag resistance because of their compact structure and outstanding performance. The common feature of the V-type engine and the T-type engine is that they both use a combination of cylinders similar to the V and T, which allows them to have better space utilization and performance.

Among them, the V-shaped engine has the characteristics of smaller size and lower center of gravity, and many high-performance models use the V-shaped engine; The T-engine, on the other hand, is more suitable for larger vehicles because it offers a better balance between steering performance and dynamics. In general, the selection of the engine should also be based on the use of the environment, engine power and other comprehensive considerations. <>

CVT is a transmission.

You're talking about vvt....

The i-VTEC is the equivalent of the upgraded VVTI-VTEC or the VVT-i is the intelligent variable valve timing and lift electronic control system, or the VVT-i is the intelligent variable valve timing system, which can be seen literally.

i-vTec has an additional lift adjustment that is relatively high-end in its class.

The i-VTEC is the Variable Valve Timing and Lift Electronic Control system used in Honda's engine.

The VVT-i is the Variable Valve Timing Intake system used in Toyota's motorcycles.

CVVT Continue Variable Valve Timing.

CVVT and VVT-i are just different in name, for example, BMW calls it Vanos

The difference is that the i-VTEC can change both the moment and the length of the valve opening, while the VVT-I or CVVT can only change the moment the valve is opened.

Theoretically, i-vtec is superior, but the mechanism is more complex, and there are more fault points, so the quality can only be compared by the stability of the respective system.

I think the CVT was like a continuously variable gearbox.

i-vTec is a variable timing system. Two different things, oh, the upstairs is wrong.

The i-VTEC is Honda's patented technology, and the difference from the VVT is that one is Toyota and the other is Honda.

VTec changes the angle of the valve by simply replacing it with a cam with a higher angle, while VVT simply changes the angle of the valve from the original cam.

These two do not conflict!

It is possible to coexist!

Safe and fuel-saving within 100,000 at present there is no rival The A3 2011 model that will be launched next month is DVVT (data from the Ministry of Industry and Information Technology, with CVT automatic, ESP, independent suspension.

China's No. 1 price-performance ratio.

In 2010, Chery became the first automobile company in China to fully master the four key technologies of chassis, engine, transmission and engine electronic management system (EMS).

Friend! You need to know the VVT (Variable Valve Timing) system. The system adjusts the phase of the engine cam through the control and actuation system, so that the opening and closing time of the valve changes with the change of engine speed, so as to improve the charging efficiency and increase the engine power.

The principle of variable valve timing (VVT) technology is to adjust the amount of intake (exhaust), valve opening and closing time, and angle according to the operation of the engine. It is the amount of air entering the air to achieve optimum and improve the combustion efficiency. The advantage is fuel saving and the power-to-lift ratio is large.

The disadvantage is that the torque in the middle section is insufficient.

The VVT of Korean cars is based on Toyota's VVT-i and Honda's VTEC technology in Japan, but compared with Toyota's VVT-I variable timing valve technology, VVT is only variable valve technology and lacks timing technology, so the VVT engine is indeed more fuel-efficient than the general engine, but it is not as fuel-efficient as the Toyota and Honda cars of Japanese cars.

BMW has already adopted this technology in previous generations of engines, such as Honda's VTEC, i-VTEC, and current engines; Toyota's VVT-i; Nissan's CVVT; Mitsubishi's Mivec; Suzuki's VVT; modern VVT; Kia's CVVT and other products are also gradually being used. In general, it is actually a technology, with a different name.

vvt--i

VVT Chinese means "variable valve timing", because of the use of electronic control unit (ECU) control, so Toyota has a nice Chinese name called "intelligent variable valve timing system". The system mainly controls the intake valve camshaft, and has a small tail "i", which is the code name for the English "intake". That's the literal meaning of "vvt i".

vvt—i.The system is the English abbreviation of Toyota's intelligent variable valve timing system, and the engine of the most advanced Toyota sedan has been widely installed with the VVT-I system. Toyota's VVT-i system continuously adjusts valve timing, but not valve lift.

Its working principle is: when the engine is converted from low speed to high speed, the electronic computer automatically presses the oil to the small turbine in the intake camshaft to drive the gear, so that under the action of pressure, the small turbine rotates at a certain angle relative to the gear housing, so that the camshaft rotates forward or backward within the range of 60 degrees, so as to change the moment of opening the intake valve, and achieve the purpose of continuously adjusting the valve timing.
