Alternator Drive
Lack of power at idle. It has been an ongoing issue for government vehicles, transit buses and commercial vehicles whose belt-driven alternators fail to produce the maximum power guideline for electric power during idling.
The problem: At idle, the alternator speed falls below its rated speed (the speed at which the alternator’s maximum output occurs). Sizing the pulley ratio to spin the alternator faster at idle will hurt fuel consumption by over-speeding the alternator for most driving conditions and may even cause the alternator to over-speed and fail when engine speeds are higher.
The solution: An alternator drive incorporating NuVinci® CVP technology, which can deliver the ideal alternator speed all the time – providing needed power regardless of engine speed, reducing speed when power is not needed and ultimately improving fuel economy. And it will do all this with minimal complexity, easy installation and low cost.
