Crema de leche. Meaning cream or milk in Spanish. It is whole milk pasteurized. It is a substance that is greasy, and has a yellowish, white color to it. It is used on fruits, salads and ice cream. It is also used in pastry shops, used to make a paste for soups or creams.
A continuously variable transmission (CVT) (also known as a single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a twist-and-go) is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios.
Automatic transmissions that use gears need to switch between gear positions, while CVT does not. Since power from the engine is continuously fed to the tires, the ride is smoother. With CVT, diameters of the areas where the two pulleys meet the belt can be infinitely varied (Figure 1). Each pulley consists of two conical plates facing each other, which by moving closer or further apart, changes the diameter of the area meeting the belt (Figure 2).
