This article describes Volvo's experimental compressed natural gas (CNG) trucks, which were developed as part of Volvo's general environmental research and development programme. Volvo is introducing 30 CNG trucks for municipal work into its home city of Gothenburg, Sweden, and is developing 20 biogas-powered vehicles. The trucks are being used in urban areas, because they have a limited range, due to the bulk and weight of their gas tanks, and because there is not yet a Europe-wide CNG supply network. Although CNG produces lower emissions of nitrogen oxides (NOx) and particulates, it produces about four times as much hydrocarbon pollution as diesel. CNG is cheaper to produce than diesel, but more expensive to handle. A CNG truck is much more expensive to construct than a diesel truck. The trial trucks are all FL10s with various chassis configurations; their CNG engines typically replace 7l diesel engines, and are less powerful than modern 96.l diesel engines. They are turbo-intercooled, with an electronically controlled waste-gate, and have an oxidation catalyst in the exhaust system, which is very important for controlling emissions. The truck's electronic control system has a range of sensors for various monitoring functions.
