ده رسم بيانى بيوضح الفرق بين الCVT و الDUAL CLUTCH فى موضوع مدى أستغلال أعلى كفاءة للموتور من الثبات و حتى الوصول إلى سرعة منتظمة على نطاق واسع من لفات الموتور
Dual clutch transmission, as the name suggests, has two clutches, one for the odd-numbered gears (first, third, fifth) and one for the even-numbered gears (second, fourth, sixth). When you shift gears, the alternate gear is already selected, and gear changing becomes faster. DCT’s approach is to raise transmission transfer efficiency in order to improve fuel efficiency. It has the same kind of mechanisms as manual transmission and, with its high transmission efficiency, in particular it can extend mileage when cruising at high speeds.
CVT skillfully uses the engine’s “best” parts
On the other hand, CVT raises fuel efficiency by using the most efficient parts of the engine. As we saw before, CVT can set the transmission gear ratio freely, and is characterized by gear changing and driving that is seamless. This transmission gear ratio can set the range of the ratio widely and whether at low speed or high speed, it is able to continue using the area that is best for mileage.
In other words, CVT tries to improve fuel efficiency by maximizing the engine’s potential. Compared to DCT, CVT is able to use the efficient parts of the engine as soon as it starts up.
CVT has also been evolving from year to year. The challenge of upgrading transfer efficiency has now been achieved, along with expanding the transfer gear ratio. It has become possible to run on the engine’s optimum rpm, with a much wider range of speed than previously.
And not only the mechanics, the software that controls CVT has also been evolving. Now it can interpret the driver’s commands through the operation of the accelerator and steering for optimal shift control. On top of improving the fuel efficiency, CVT’s capabilities are advancing to allow you to drive just as you want.
و ده هو سبب توفيره للوقود....فى نطاق معين لكل موتور يجب الوصول له لتحقيق أعلى كفاءة منه و أقل أستهلاك للوقود و ده بيحصل عادة وقت القيادة عند السرعة المثالية (حوالى 90~100 كم/ساعة) و دون تسارع...فى الCVT الكلام ده بيحصل طول فترة التسارع مش بس وقت الوصول إلى السرعة المثالية....
