Characterization of diesel injection processes by laser Mie scattering
The heterogeneous combustion process of liquid fuel, e.g. in diesel engines, is significantly affected by the quality of the mixing process. The mixing process depends strongly on spray penetration inside the combustion chamber. Investigation of spray penetration by measuring spray tip penetrations and cone angles inside a research engine has failed to establish a sufficient description of the process by means of empirical or theoretical equations for high speed diesel engines. Systematic investigation of the injection process with injection durations of approximately 0.5 ms is necessary in order to derive new equations from existing equations or from new statements. An extended comparison has been made between measurements performed inside a Volkswagen DI diesel engine using laser Mie scattering and models described in the literature. Differences are discussed in detail. Additionally, the planned Mie scattering experiments for the derivation and validation of new equations are described.
