"Compressed Natural Gas (CNG) is an especially economical and environmentally friendly fuel. Bosch delivers bifuel injection systems with two seperate fuel circuits. The engines runs on either gasoline or natural gas. When the natural gas begins to run out the system automatically switches to gasoline operation.
The Bosch technology for CNG drives makes vehicles clean, economical, and powerful, with a long service life and original equipment quality. The Bosch CNG system reduces CO2 emissions by 25 percent compared with similar gasoline engines. The total CO2 impact of CNG vehicles can be cut by much more than 25 percent by using biomethane to power the vehicle."
