Eaton Hybrid System to power fuel efficient IC school bus16 February 2011

Navistar's IC Bus CE Series hybrid electric school buses, claimed to run at 30% better fuel economy than diesel engine equivalents, is now being equipped with Eaton's hybrid electric power systems.

The power plant, which has more than 100 million miles of real-world driving under its belt, also emits up to 35% less NOx and 85% less diesel particulates. And it features Eatonk's hill start assist.

"We are pleased to incorporate Eaton's proprietary hybrid system to improve fuel economy by up to 30% and significantly reduce greenhouse gas emissions," says John McKinney, president of IC Bus.

Eaton worked with IC Bus to develop its hybrid system for school buses. It now combines the MaxxForce DT with MaxxForce Advanced EGR (exhaust gas recirculation), coupled with a 44kW electric motor.

Regenerative braking is used to charge the lithium-ion batteries, while also reducing wear and tear on the brakes, and Eaton matches the system to an automated six-speed Eaton transmission.

Dimitri Kazarinoff, vice president and general manager for Eaton's Hybrid Power Systems Division, says that maintenance is simple, requiring only a normal coolant check and battery compartment filter replacement at regular maintenance intervals. And IC Bus and Eaton back up the entire hybrid system with a five-year unlimited mileage warranty.
