اعلى قوة حصااان للموتور بتبقى على عدد لفاات عالى زى 6000rpm وكلنا متفقين على كدة طيب انا عربيتى منوال لما باجى احرق عشاان اجرى بجيب اخر ال rpm او قبل اخرة بشوية عشان يبقى بيرفكت شيفت طبعا مش ريد زوون طيب حد بيقى يفهمنى ال cvt دة عشااان الى انا لسة شايفة امبارح مع واحد صاحبى معاة لانسر 2007 ان ال rpm مبيطلعش لفووق خااالص كان بيسبت عند 4 rpm والعربية بتحاول تجمع اكتر على نفس ال rpm دة طب ما انا كدة مش باخد كل قوة الموتور وبرضوا نفس الكلام دة فى الصور الى هنا ! فين بقى الافضل فى كدة ياريت حد يفهمنى

Top Tec ATF 1400,CVT Technology
CVT transaxles of this type use a very specific type of lubricant to combat the high friction / heat generation and then heat dissipation to the case and transmission cooler. I am not aware of any heat related issues, only belt breakage. New Generation XTRONIC CVT Many people find the CVT disconcerting at first because of the way cars with CVTs sound. When you step on the accelerator, the engine races as it would with a slipping clutch or a failing automatic transmission. This is normal -- the CVT is adjusting the engine speed to provide optimal power for acceleration. History of the CVT Leonardo DaVinci sketched the first CVT in 1490. Dutch automaker DAF & VOLVO first started using CVTs in their cars in the late 1950s, but technology limitations made CVTs unsuitable for engines with more than around 100 horsepower. In the late 80s and early 90s, Subaru offered a CVT in their Justy mini-car, while Honda used one in the high-mileage Honda Civic HX of the late 90s. Improved CVTs capable of handling more powerful engines were developed in the late 90s and 2000s, and CVTs can now be found in cars from Nissan, Audi, Honda, Ford, GM, and other automakers. The Benefits of CVT Technology هنا ! فين بقى الافضل فى كدة ياريت حد يفهمنى
The lightweight build of Nissan’s Xtronic CVT and its ability to instantly accelerate makes for a fast ride that even those with the ultimate need for speed can appreciate. As a standard automatic engine shifts gears the engine’s RPMs rise and fall, performing in less than optimal ranges; but the CVT’s technology controls the output of the transmission to make sure that the engine’s parts are always moving at the perfect rate for maximum efficiency and speed. This optimum efficiency erases the transmission’s need to ‘downshift’ allowing acceleration to take place instantly. The Future of Nissan and the Continuously Variable Transmission الافضل فى كده! As part of Nissan’s continued commitment to deliver eco-friendly cars to consumers the auto giant is dedicated to fully implementing the CVT system. After introducing the use of the Xtronic CVT in 2002, Nissan began the first widespread distribution of the transmission in America by implementing CVT technology in their 2003 Nissan Murano SUVs; and by 2006 they were integrating the transmission into almost all of their model’s engines. Nissan has said they will continue to invest in CVT technology and research the most fuel-efficient, eco-friendly engine mechanics. To prove their dedication to better-performing vehicles and their customers Nissan has doubled their warranty on their Xtronic Continuously Variable Transmission from five years or 60,000 miles to 10 years or 120,000 miles. For those who have already spent money on transmission repairs Nissan is offering reimbursements and working with certified mechanics to reduce the cost of repairs. Top Tec ATF 1400 Top Tec ATF 1400 is a high performance automatic transmission fluid of the new generation based on synthetic technology. It was developed specifically for use in CVTs with thrust link belt or a gear chain made of steel. The basis of modern base oils and select additives offer the best possible anti-froth protection, which is necessary for CVTs. It also features a very good stability against aging and oxidation. Top Tec ATF 1400 is tried and tested, most notably in the Mercedes-Benz A-Class and B-Class Autotronic transmissions and in continuously variable automatic transmissions (Multitronic) in Audi vehicles. For the new generation of CVTs with thrust link belt or a gear chain made of steel. The specifications and instructions from the unit or vehicle manufacturer must be followed. Optimum effectiveness is only possible when the product is used unmixed. التعديل الأخير تم بواسطة cars admire ; 21-10-2011 الساعة 02:34 AM |
