Bosch Long Haul Extreme alternator offers fuel savings
Robert Bosch LLC has launched the new heavy duty Long Haul Extreme alternator. Bosch says it is designed to provide superior power output on the road and at idle, with an advanced electronics and design that ensure trouble-free operation, increased battery life and significant fuel savings.
“By optimizing brushed alternator technology and state-of-the-art electronics and components, Bosch is able to eliminate the need for brushless technology and provide a compact, lightweight, rugged 170- or 200-amp alternator highly suited for the severe operating conditions in today’s commercial vehicles,” said Fred Padgett, group Article manager, Starters and Alternators for Bosch. “The use of advanced technology in the new Long Haul Extreme brushed alternator (AL9920LL, AL9921LL, and AL9922LL) produces ‘extreme’ long life while exceeding the performance of brushless alternators. Furthermore, it weighs up to 34 percent less than brushless alternators.”
- Intelligent Battery Sense
- Extreme Multifunction Regulator
- Optimized Brush Composition
- Thermal Protection
- Extreme Bearing Technology
“These features allow the Bosch alternator bearings to run 10 to 15 percent cooler. When run at 6,000 alternator rpm, the Bosch bearings operate at less than 120 degrees Celsius, while the closest competitor is 125 degrees, with some as high as 140 degrees,” Padgett said.
