Chrysler Group LLC and U. S. Environmental Protection Agency announce new research project for hydraulic hybrid powertrain.This new business-government research project to include design and development of experimental hydraulic hybrid powertrain.hydraulic hybrid powertrain is battery-free hydraulic hybrid tech and it compresses gas to make power……..

Chrysler Group LLC and the U. S. Environmental Protection Agency (EPA) announced a partnership to determine the possibility of adapting a hydraulic hybrid system for large passenger cars and light-duty vehicles.The announcement was made at the EPA laboratories in Ann Arbor, Mich., following a meeting with Sergio Marchionne, Chrysler Group CEO and Lisa P. Jackson, Agency Administrator for the EPA.

The hydraulic hybrid system developed by the EPA‘s lab in Ann Arbor, is well known and currently used in industrial applications, including large delivery trucks and refuse trucks across the country. The technology has shown substantial increases in fuel economy when compared with traditional powertrains in the same type of vehicles. Working together both parties hope to reduce the size and complexity of the hybrid system and produce a technology that is sensitive to the needs of drivers for smooth and quiet operation.

The system produces power with engine torque driving a hydraulic pump that charges the high pressure accumulator of up to 5,000 p.s.i.he Chrysler Group has actively adopted fuel-saving technologies including cylinder deactivation on V-8 engines, a new MultiAir system that is being introduced on the Fiat 500 today and will introduce an eight-speed transmission in the 2011 Chrysler 300 that will be introduced later this year. Chrysler Group also will introduce 150 Ram 1500 trucks with a plug-in hybrid system in the coming months as part of a project with the U. S. Department of Transportation.
