Hydraulic Hybrid Systems and Equipment Maintenance Innovators Announce Partnership Two Colorado companies will manufacture and distribute hydraulic hybrid systems for fleet vehicles Loveland, Colorado (September 3, 2009) — Hydraulic Hybrid Systems, LLC (HHS), a subsidiary of Lightning Hybrids Inc., today announced a partnership with Equipment Maintenance Innovators (EMI-Global) to distribute its hydraulic hybrid retrofit systems. This partnership brings together two Colorado companies to manufacture and distribute fuel-efficient hydraulic hybrid technology for light and medium duty fleet vehicles. The hydraulic hybrid systems are designed to save fleets millions of dollars a year in fuel costs by providing fuel mileage increases of over forty percent and greatly reducing greenhouse gas emissions compared to a vehicle’s fuel mileage prior to the retrofit. |

The HHS solution involves inserting a high-efficiency, light-weight hydraulic propulsion system within the driveline of a vehicle. This system is designed and engineered to be installed in fourteen hours, including all controls and wiring harness, by a certified installer. The system has been successfully tested by the EPA and at various state sponsored university technology incubators including a program at Colorado State University. Successful installations have been on vehicles from the Ford Excursion to Class 8 vocational trucks.
In this very simple and effective configuration a hydraulic pump is coupled to the driveline via a belt and clutch. This parallel hybrid system can deliver over 40 percent improvement in fuel economy, depending on the amount of braking seen during a normal drive cycle. The pump and accumulators store braking energy, and upon acceleration, the pump becomes a motor that uses the stored energy in the accumulators(s) to provide torque to power the wheels. The large fuel efficiency gains are achieved by regenerating the braking energy that is normally lost to heat, and using this energy instead of (and in addition to, if needed) the internal combustion engine for acceleration.
The hydraulic hybrid system includes a heavy-duty Eaton hydraulic pump and motor, an ASTM certified high pressure accumulator tank, a low pressure reservoir, a valve block, HHS control system, brackets and associated certified hoses. System operation is seamless to the operator.
In addition to serving the high-efficiency market through improved fuel mileage, the HHS solution serves the green tech market currently driven by federal and state mandates, as well as swelling consumer sentiment, by dramatically improving emissions. This retrofit solution reduces carbon emissions by more than 40 percent, depending on the engine technology and age that it is mated with. |
