IdlePro Extreme 350-, 420 amp alternators offered on Blue Bird rear engine diesel, CNG school buses

Prestolite Electric has been awarded standard position by Blue Bird o supply IdlePro Extreme alternators from Leece-Neville Heavy Duty Systems. Blue Bird All American rear engine (RE) diesel and CNG-powered school buses will be offered with IdlePro Extreme 350- and 420-amp alternators as standard and optional equipment for models utilizing a Cummins 2021 engine.

The Cummins 2021 engine designs found on Blue Bird All American RE diesel and CNG-powered buses require a specific approach to its corresponding charging systems, Prestolite Electric noted in a press release. This particular bus model and engine combination utilizes electric fans cooling the radiator that are powered by the IdlePro Extreme alternators.

For applications utilizing a Cummins L9 or B6.7 300-horsepower engine using a six-fan cooling system and the lower horsepower engines of the same design with A/C will be offered with the IdlePro Extreme 350-amp alternator as standard. For the bus models running a 2021 Cummins L9N engine, the IdlePro Extreme 420-amp alternator will be standard equipment.

Features of the IdlePro Extreme 12V alternators, as noted by the manufacturer, include:

  • 12-volt, 280-, 325-, 350- and 420-amp outputs available in a brushless design.
  • Minimum of 90% of a unit’s rated maximum output at engine idle, in certain applications.
  • Remote Sense capable—returns battery to full charge between stops and reduces overall charging time.
  • Auxiliary Draft Cooling design—fan and front housing design and integration for temperature control of the front bearing. Front bearing is kept 10°C cooler as compared to traditional external fan designs.
  • Rated up to 125°C—ideal for the high-temperature environment commonly found in school bus applications.
  • E-coated heavy-duty design offers reduced corrosion and improved vibration resistance.
  • Isolated Ground Technology reduces stray voltage currents traveling through the engine, helping to reduce component wear and eliminate potentially severe electrolytic damage.
  • Assembled in America.
  • No core.
