What is variator system?
Variator is a system for varying the valve opening of an internal combustion engine. This allows the engine to deliver high power, but also to work tractably and efficiently at low power.
What does a Polini variator do?
The main feature of all the Polini variator is the increase of the variator range. Usually it is possible to modify the pulley ratio on the belt obtaining in this way a short gear for the starting and a longer gear exploit the maximum speed of your scooter.
What is a clutch variator?
On modern twist and go scooters, a variator drive system gives the optimum gear ratio between the engine and the rear wheel. This enables the engine to work at the best RPM in comparison to road speed and conditions. The variator works upon the ratio of the diameter of the front and rear drive belt pulleys.
What is a variator on a motorcycle?
A typical feature of motor scooters is the variator, an ingeniously simple means of achieving continuously variable power transmission. Proper maintenance and correct adjustment of the variator will improve the road performance of your scooter.
What does a performance variator do?
A variator itself is the main driving part of a continually variable transmission (CVT). Where a gearbox has gears, each with a fixed gear radio, a CVT smoothly transitions through its gearing range. Variators are used in scooters, and even some modern cars for a couple reasons.
What is a camshaft variator?
What is a camshaft variator and what does it do? The camshaft variator is part of the Variable Valve Timing System (VVTS.) This system alters the timing of the valve lift in order to improve gas mileage, lower harmful emissions, and ensure high performance whenever you drive.
How do I stop my scooter from dragging?
The panacea for dragging hard parts may initially sound simple. Slow more before the corner, use a path of travel that reduces the need for lean angle, and try to be on the throttle near the apex of the corner so that we are raising our suspension to increase ground clearance when we need it the most.
How do I increase my CVT speed?
By changing your CVT stock rollers to a lighter weight, you can increase acceleration off the mark, and by adding weight, you can increase top speed.
How does Nissan VVT work?
Variable valve timing works by changing the timing interval for fuel and air injection into the combustion chamber in order to maximize burn rates, thus lowering fuel usage. Most VVT engines can dynamically change these ratios and the timing of those injections at multiple RPM rates.
What do lighter rollers do on a scooter?
Do heavier rollers increase top speed?
Characteristics of the Weight Rollers Generally, if you choose a lighter weight, the setting will emphasize low speed; if you choose a heavier weight, the performance will show more on high speed.
What is the cause of dragging?
Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag.
What do the rollers do on a scooter?
Almost all modern scooters feature a CVT or centrifugal clutch (Automatic). A major drive force inside this clever type of clutch is the roller weights that move inside the roller cage which directly determine how quickly the gear ratio moves from slow to fast during acceleration.
What is variator in CVT?
A variator (CVT) is a continuously variable transmission that, within a certain range, allows you to achieve the most smooth change in the gear ratio. The main difference between the variator gearbox and its analogues is the rather efficient use of the internal combustion engine power.
