Second generation biofuels have the potential to contribute to the reduction of overall C02 emissions from traffic without entering an ethical contradiction to food production. Within the presented project the suitability of preselected 2"d generation biofuels for engine cornbustion is investigated experimentally. A distinctive feature of the project is the investigation of the fuel supply into the internal combustion engine in three different ways. Next to the common direct injection of diesel-biofuel blends. the biofuel is also fed via intake manifold injection parallel to direct diese! Injection into the combustion chamber. In addition. a thermo chemical recuperation system is investigated, where hat exhaust gas is used to support biofuel reforming reactions to combustible syngas (H2, CO). The generated syngas is injected into the intake manifold and is then ignited via diese! pilot injection. The reforming of biofuels is investigated experimentally in a separate reactor on a synthesis gas test bed. In this paper the results with ethanol and butanol as alcoholic biofuels are presented.
