To quantify environmental advantages of gas technology, the Flemish Institute for Technological Research (VITO) carried out measurements of different bus technologies. Fuel consumption, emission of nitrogen oxides, carbon monoxides and hydrocarbons of 8 buses were measured in the Brussels traffic. Three technologies from the early 1990's were taken as a reference: the Euro-1 diesel, the current Brussels public transport company natural gas bus, and a LPG bus. Comparisons were made with the modern diesel bus (Euro-2) and the newest buses on natural gas and LPG. To achieve minimal emissions, the best available technology for buses on natural gas or LPG is multipoint injection, the constructors of engines for heavy-duty traffic are changing from carburetor to fuel injection. The best available gas technologies has emissions that can be 50 to 95 per cent lower than the most modern diesel bus. Users mentioned problems at the introduction of vehicles on gas, such as lower reliability and availability. The cost price continues to be a disadvantage of buses and trucks on gas. The purchase price of the vehicle remains higher and the workplace must be adjusted for maintenance and repairs of vehicles on gas.
