BUNDLES OF WAYS TO GET DOWN TO ZERO

This article reports on Volvo's Project 2690, where a team of engineers has been testing ideas for making city trucks more environmentally friendly, safe, and efficient. When begun in February 1994, the project aimed to build within 18 months an urban 'environment concept truck' (ECT) meeting these objectives. The ECT prototype is a fascinating preview of the types of vehicles that transport engineers can expect to be managing and maintaining in the 21st century. Volvo engineers hope that its full-size working ECT will at least stimulate significant reactions for truck operators, drivers, and legislators. ECT's drive-line has: (1) an ethanol-powered gas turbine, which could also be set to run on methanol or almost any liquid or gaseous fuel; (2) a high-speed electrical generator; (3) nickel-metal-hydride batteries; and (4) an electric motor fitted to the rear axle. The 400-volt battery pack can provide about 25km of zero-emission operation in a city centre; outside city centres, the gas turbine would be used. The maximum power of the generator and batteries combined is 142kW (170hp), and the truck's maximum geared speed is 100kph. There is an 'intelligent' active suspension system, with a hydraulic cylinder at each wheel.
