High Efficiency, High Power Density Small Hybrid System

摘要

The engine system concept disclosed in this proposal meets or exceeds each of the goals stated in Solicitation DARPA 08-010. Our hydraulic hybrid concept will provide extremely high efficiency while reducing weight and increasing power density. The core of this new concept is a standard four-cycle internal combustion engine power cylinder. However, the power cylinder interfaces with a hydraulic system that sends power to a hydraulic hybrid power unit. The goals of high efficiency and low weight are met in three ways: through variable geometry; through elimination of heavy components; and through hybrid operation.
