Stryker Auxiliary Power Unit


As part of the development of the Stryker Light Armoured Vehicle for the US Army, Mechron personnel helped to develop an under-armour auxiliary power unit (APU) as part of the overall vehicle system design. The APU is an anti-idling device, powering the Stryker while the main engine is not in operation, reducing fuel consumption and maintenance requirements. The Stryker APU is a 3.8kW, 28 VDC liquid-cooled generator set designed for underhood operation in harsh environments, including temperatures from -50°C to +100°C and extreme shock and vibration. The APU is a fully integrated design, sharing its cooling system with the Stryker’s main engine. This APU is equipped with an SAE J1393 CANBUS data / diagnostics interface for remote operation and diagnosis. The design was successful and 1,400 APUs were supplied to GDLS for installation on their production line.
