Nissan judge, new teknoligi is an important step to improve the work efficiency of conventional engines (motor fuel).
Irit 10 Percent
This new Xtronic CVT can improve fuel efficiency to 10 percent compared with the CVT is used today (compared with the same vehicle). Another advantage, gear ratio can be made to 7.0 and friction is reduced to 40 percent.
Incorporate new Nissan Xtronic stretcher with Adaptive Shift Control (ASC) or the gearshift settings adjusted to the driver's style and road conditions. The result, this new transmission more responsive acceleration plus the increasingly fierce. The car is also more stable accelerated at high speed and reduce noise.
Planned, this transmission will be introduced first time in Nissan model to be marketed in the United States in 2012.
7.0 Comparison
To get a comparison of 7.0, a smaller diameter pulley shaft coupled with a belt (belt) the results of the latest engineering. Range comparison between the two pulleys are increasing but still small axial distance increments. The result, comparison of rotation of the engine displacement to the "output" transmission can reach 7.0, especially on the 2.0 liter engine. Nissan to assess this, first achieved accomplishments in the world.
Friction Down 40 percent
For this, Nissan uses a smaller oil pump. This method can be carried out for oil leaks that can occur dicegah.Tekanan oil can be deducted because of friction between the surface of the pulleys and the belt has to be reduced.
Furthermore, used oil with a special formulation, which is a low viscosity. Friction was reduced. For this, 60 percent of the oil pump components are modified.
Shift Control (ASC)
ASC constantly monitors the movements of the driver through the acceleration (pressing the gas pedal) and vehicle speed. ASC then selecting the optimal gear ratio according to the driver's working conditions. Amazingly, the driver can determine the engine speed and the speed of the car when berakseleasi.
Hybrid Cars
Nissan also considered, the new CVT technology is ideally suited for hybrid cars with front wheel motion, both in terms of cost and packaging. Combined electric motor, two new-generation Xtronic CVT clutch, lithium-ion and 2.5-liter supercharged engine, can be packaged in a compact. It is not necessary to design a special body, it can even accommodate a 3.5-liter.
