Abstract
Separate from the vehicle's engine, a self-contained internal combustion engine supplies hydraulic power to drive a product pump on a bobtail. The self-contained engine, which can itself run on propane, is provided as part of a preassembly which includes the hydraulic pump, the hydraulic fluid tank, a heat exchanger, and a solenoid controlled start-up valve. The preassembly is mounted as a unit to the side of the bobtail in front of the rear wheels, powering the product pump at the rear of the bobtail while the vehicle's engine is off.
