The HyTrans project is a collaborative development of a micro hybrid demonstrator vehicle based on an urban delivery van. The project partners consist of Ricardo, Ford, Gates and Valeo and the project is co-funded by the UK Energy Savings Trust under the New Vehicle Technology Fund. A concept study analysis has been performed for an urban delivery van in order to identify the impact of different cost efficient belt driven micro hybrid concepts on fuel consumption performance over representative real world delivery driving conditions.

An emissions programme has been undertaken to gain information on the effect of selected fuel parameters on gasoline direct injection (G-DI) vehicle technology(1) with respect to exhaust emissions. Seven fuel parameters, namely aromatic, methyl-tertiary-butyl ether (MTBE), sulphur and olefin content as well as 3 distillation parameters covering the whole boiling range, were independently investigated. It was found that, overall, the fuel effects on regulated (THC, CO, NOx), particulate (Pm), and CO2 emissions were relatively small.
