Delhi Transport Corporation (DTC) has ordered 3,125 natural gas buses equipped with Cummins Westport Inc.’s (CWI) B Gas Plus engines. The 5.9-liter, six cylinder 230 hp (172 kW) B Gas Plus engines, powered by compressed natural gas (CNG), are licensed by CWI and manufactured by Cummins India Ltd. (CIL).
The order of more than 3,000 engines is CWI’s largest single order to date.
New Delhi began an aggressive natural gas vehicle program ten years ago, beginning with the conversion of approximately 60,000 auto rickshaws to CNG for fuel. A Supreme Court order in 2002 mandated the city’s entire bus fleet to convert to cleaner-burning CNG. A government report showed that while the number of vehicles on the road has doubled, the pollution rate has halved.
Outside of New Delhi, ten other major Indian cities also have aggressive natural gas vehicle conversion programs.
DTC is one of the main public transport operators of Delhi and operates more than 3,000 CNG buses on 773 routes throughout Delhi and surrounding areas. Delhi operates one of the largest CNG bus fleets in the world.
