Driving with natural gas: NGT (natural gas technology)
In terms of both ecology and economy, natural gas drive is a viable alternative to conventional drive concepts. In comparison with conventional gasoline or diesel fuels, its advantages lie in a lower carbon content and low-emission combustion. Moreover, natural gas engines run very quietly and produce less CO2 than diesel engines.
To date, natural gas vehicles still have the disadvantages of intricate fuel storage in bulky pressure cylinders and a limited filling station infrastructure. Thanks to their bivalent drive units, NGT passenger cars such as the Mercedes-Benz E 200 NGT BlueEFFICIENCY or the B 170 NGT BlueEFFICIENCY can run either on natural gas or on premium gasoline.
The Mercedes-Benz Sprinter NGT BlueEFFICIENCY with bivalent natural gas drive has also been available since 2008. The Mercedes-Benz Citaro CNG is manufactured both as a solo and an articulated bus with natural gas engine; more than 1,600 of these vehicles are already in operation throughout the world. This was the first line-service urban bus with natural gas drive to comply with the EEV (Enhanced Environmentally Friendly Vehicle) exhaust standards. The Mercedes-Benz Econic NGT likewise undercuts the Euro V and EEV limits and is characterized by low noise emissions; around 1,000 of these trucks are on the roads of Europe in municipal service, collecting, and distribution operations. 1,300 natural gas vehicles on the basis of the MT45 walk-in delivery van have been delivered since 2000 by the Freightliner Custom Chassis Corporation (FCCC). |
