The distance between the drums is controlled by the engine vacuum in the inlet manifold and engine RPM, through centrifugal weights inside the drums. Between the two pulleys runs a drive belt. As a result of the change in the distance of the conical drums in both pulleys, the diameters and so also the reduction ratio changes continuously. [2]
This design was patented for Fiat and was used in the engines of the 128 and 130, and even the Ferrari/Fiat Dino V6 engine was converted to this system. Fiat was a pioneer in engine development during the time period, using toothed rubber belt driven camshafts and aluminium alloy heads. Earlier Fiat Twin Cam engines were actually O.S.C.A. designs.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
The NuVinci CVT system has a small number of parts. [5] [6] Most CVTs have lower mechanical efficiency than competitive conventional transmissions.Since any CVT may allow a power plant, human or motorized, to operate at (or closer to) its speed of optimal efficiency, output torque or output power, the NuVinci CVT may improve a system's overall efficiency or performance compared to a ...
A cam engine is a reciprocating engine where instead of the conventional crankshaft, the pistons deliver their force to a cam that is then caused to rotate. The output work of the engine is driven by this cam. [1] A variation of the cam engine, the swashplate engine (also the closely related wobble-plate engine), was briefly popular. [2]

Three-speed sliding-gear non-synchronous transmission Non-synchronous "crash" gearbox; commonly used today in semi-trucks and tractors, and formerly used in automobiles pre-1950s. A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require ...
