CNG bus, CNG Truck, CNG Vans manufacturer
Most compressed natural gas (CNG) buses(or trucks, vans) are equipped with a diesel engine modified to a spark-ignition engine that is optimized for the use of natural gas. Gas cylinders are installed that can be refueled at gas stations with compressed natural gas. Such engines can be of two basic types:
- Stoichiometric - this type enables the use of a three-way catalytic converter as in common gasoline cars.
- Lean burn (high air/fuel ratio) - this type is 10-20% more fuel efficient than stoichiometric engines, but also has higher NOx emissions. A three-way catalytic converter is unsuitable, but oxidation catalysts can be employed. The great majority of heavy-duty natural gas engines are of this design.
In general, CNG buses(or trucks, vans) are between 17% and 41% less fuel efficient than conventional diesel buses. They have a substantially lower driving range than diesel buses - e.g. in CNG buses are described as having a driving range of about 300 miles (of course depending upon the capacity of the gas cylinders) compared to a little more than 400 miles for diesel buses.
