Alternative Fuels for Alternative and Conventional Diesel Combustion Systems

In this paper, results from conventional, Homogeneous Charge Compression Ignition (HCCI) and Split Combustion (SC) combustion processes in combination with alternative fuels are discussed.

First the results of the conventional combustion and Diesel fuel as reference are shown; thereafter the results of a blend of Diesel, Rapeseed Methyl Esther (RME) and ethanol and two blends of Diesel and butanol are described.

Second the same fuel and blends are used with the (partially) homogeneous combustion systems to evaluate the possible reduction of emissions and fuel consumption. In addition to the limited emissions some measurements of the particle size distribution are carried out.
