AFS demonstrates natural gas hybrid bus engine controllers


Alternative Fuel Systems Inc. (AFS) announced that together with its partner Advantek Fuel Systems Pvt. Ltd. (“Advantek”) the company has successfully developed sophisticated engine controller technology that was used in three natural gas hybrid buses manufactured by India’s Ashok Leyland. These “HYBUS” demonstration vehicles were used to provide transportation services for VIP’s at the recent Commonwealth Games held in Delhi. Ashok Leyland is the largest manufacturer of buses in India. They are also a major provider of heavy duty commercial trucks and specialty vehicles.

AFS President and CEO Jim Perry stated: “With Advantek, we were pleased to be contracted by Ashok Leyland to develop engine control hardware and software for their combination compressed natural gas engine / electric drive hybrid bus. The controller incorporates robust and high speed communication software that allows it to exchange information with other bus systems, including the electric drive. In this project, AFS showcased its expertise in design and manufacture of engine control systems for use in the most advanced applications.”

Mr. Perry also added: “Clean burning natural gas provides significant economic and environmental benefits compared to diesel engines. The integration of a hybrid electrical drive with the natural gas engine in these buses is an excellent approach to improve fuel economy. When these types of vehicles become mainstream products, AFS will already have a track record in the leading edge technology required.”

AFS, based in Calgary, Canada, is a leading developer and manufacturer of natural gas vehicle engine controllers and associated components.
