ENERGY EFFICIENCY IMPROVEMENT AS A TOOL FOR INFLUENCING FUTURE ENGINE TECHNOLOGY. ENERGY EFFICIENCY IN LAND TRANSPORT. PROCEEDINGS OF A SEMINAR ORGANISED BY THE COMMISSION OF THE EUROPEAN COMMUNITIES, DIRECTORATE GENERAL FOR ENERGY, LUXEMBOURG, MAY 16-18, 1988

This paper describes two basic fuel economy measurement test procedures which are mandatory in the USA and Europe. Measurements of selected engine/transmission concepts are compared with real life fuel consumption and evident differences are discussed. The fleet averages of different car manufacturers in the USA and Europe are provided and the influence of individual technical measures and environmental prerequisites such as emissions legislation or fuel prices are demonstrated. A selection of technical measures for improving fuel economy in real life are explained. These include automatic engine shut off; energy mode; reduced energy mode using an inertia benefit system; and internal engine modification for producing a variable compression ratio. Methods to reduce fuel consumption by regulating traffic flow are also described briefly. For the covering abstract of the conference see IRRD 824263.
