1 10. AFTER-LIFE COMMUNICATION PLAN Even though the FIE system is not mature enough to be evaluated in a field test, the technology, together with the redesigned low pressure fuel system, will be utilized in a DME concept vehicle, which will be displayed in seminars by Volvo during August- October 2007 as one of seven CO2 free vehicles [2]. The Volvo Group is studying and assessing all of the renewable fuels that could conceivably be used for Volvo products. The seven alternatives that are being evaluated are; biodiesel, synthetic diesel, DME, methanol/ethanol, biogas, biogas+biodiesel, hydrogen+biogas. The DME presentation given in the seminars is presented in Annex 11.

3 DME Dimethylether DME Dimethylether Technical presentation Arne Ohlsson Annika Carlsson Volvo Trucks 2007 DME Dimethylether Objectives Minimise CO 2 emission levels Retain diesel engine performance Offer good fuel economy Limited cost for vehicle adaptation Volvo Trucks

4 DME Dimethylether Characteristics DME is an excellent compression-ignition fuel Low formation of particulate emissions Handled and stored as a liquid similar to LPG Aerosol propellant Volvo Trucks 2007 DME Dimethylether Challenges Low viscosity and lubricity High compressibility DME dissolves most rubber and plastic materials Limited action range 55% Volvo Trucks

5 DME Dimethylether Technical solution Standard diesel engine technology Fuel system adapted to viscosity, lubricity and vapour pressure Tank solution similar to LPG vehicles Special sealing materials Adapted electronic control technology Volvo Trucks 2007 DME Dimethylether Fuel system Low pressure system Fuel tank High pressure system Back pressure rail Pressure governor Fuel cooler Common rail High pressure pump Feed pump Control valve Injector Volvo Trucks

6 DME Dimethylether Benefits Diesel efficiency and performance High torque at low engine speed Low CO 2 emissions from bio sources Reduced noise levels Simplified exhaust after-treatment systems Potential for good fuel economy Volvo Trucks 2007 DME Dimethylether Potential Useful for local transport work as well as long haulage Concept vehicle with great potential Resources to take it to the market When the infrastructure is there Volvo Trucks
