ProPulse®
Hybrid Diesel-Electric System with Export Power
Power. On the move.
Designed for the performance demands of heavy-duty vehicle applications, the Oshkosh® ProPulse® hybrid diesel-electric system dramatically improves fuel economy up to 20 percent and serves as an on-board generator with enough output to power an entire airfield or hospital.
Performance Capabilities
Allows compact, lighter weight vehicle designs
On-board generator delivers up to 120 kW of AC power for external operations
Already proven effective on the Oshkosh® Heavy Expanded Mobility Tactical Truck (HEMTT) A3 and Medium Tactical Vehicle Replacement (MTVR), ProPulse technology uses a modular series-hybrid arrangement to simplify the transmission of power to the wheels. Its diesel engine powers a large electric generator distributing power to each axle module, which is driven independently by a dedicated motor controlled from its own power converter. And life-cycle costs are dramatically reduced because the full electric system lowers torque throughout the drivetrain and regenerative braking increases brake life.
Fuel Economy
% Fuel Economy Improvement Over Conventional Driveline Vehicle*
+35% at 20 mph (32 kph) cruising speed
+20% at 60 mph (96.5 kph) cruising speed
+30% start/stop (0-25 mph; 0-40 kph)
*Preliminary Oshkosh internal test data
ProPulse hybrid diesel-electric system enables significant fuel economy because of a tailored engine control strategy.
