Volvo gets first order for biogas buses
The order includes the Volvo 8500 intercity bus model and the fleet will begin running in July next year.
The buses consist of a conventional diesel-powered vehicle containing gas tanks attached to the roof. These tanks inject gas into the engine, producing a combination of air and fuel.
The diesel engine will utilise minimal levels of either conventional diesel or biodiesel, however if the gas tank is empty the engine can still operate on diesel only. The gas will be stored in the tanks in a gaseous state.
