Tata Motors and ATFCAN in CNG Bus Demo for New Delhi

Advanced Technologies & Fuels Canada Inc. (ATFCAN) and Tata Motors have entered into a partnership to launch a lean-burn compressed natural gas (CNG) bus demonstration project in New Delhi, India.

The project will involve six buses designed for transit and intercity applications that feature new CNG engine and fuel storage systems. Work on the project will begin immediately and the demonstration buses will start rolling in January 2007.

Cummins Westport will provide the engines and Dynetek Industries will provide the lightweight compressed natural gas storage systems.

In January, Cummins Westport and Cummins India Limited (CIL) announced the production launch of CWI’s B Gas International (BGI) natural gas engine in India. With ratings from 150-230 horsepower, the B Gas International lean-burn spark-ignited natural gas engine adheres to Euro-3 emissions standards.

The replacement of current CNG and diesel engines with new lean-burn CNG engines will result into lower emissions, increased fuel-efficiency and increased reliability. The new roof-mounted cylinders are more than 60% lighter than those currently in use and will provide bus operators with extended driving range, as well as improved vehicle fuel economy.

Overall, with nearly 10,000 CNG buses in service, Delhi has the largest clean natural gas bus fleet in the world. Air quality in New Delhi has improved dramatically since a Supreme Court order in 2002 mandated the city’s entire bus fleet to convert to cleaner-burning compressed natural gas (CNG).

Tata Motors has been manufacturing and marketing CNG buses since 2000, in a step designed to improve emission standards and to offer better fuel economy. More than 60% of buses in service in Delhi are Tata Motors CNG buses. The company has introduced CNG buses also in Mumbai and Gujarat. The company is also experimenting with buses run on biodiesel in Pune.

This bus demonstration is part of CNG India: Clean Energy Works, an overall compressed natural gas project developed by ATFCAN and supported by the Government of Canada, Natural Resources Canada, and the Technology Early Action Measures Program under the Climate Change Fund.
