The relevance of this work is due to the need of preliminary engineless assessment of performance factors for diesel engines working on alternative fuels. The aim of the work is a development of programmed techniques for performance characterization of a diesel engine. The work was carried out according to a standard methodology for determining combustion procedure performance factors developed by the Central Research Diesel Institute and Bauman Moscow State Technical University. The authors suggested performance calculation algorithms for preparatory and master phases of the combustion procedure in a diesel engine cylinder working on composite fuel and emulsions doped with aliphatic alcohols and plant oils. A calculation and a comparative assessment of precision of measurements in design and experimental data of an ignition delay period, cycle peak pressure and combustion procedure inflexibility were performed. Based on the results of the research, conclusions were drawn on the possibility of a preliminary performance assessment of diesel engines working on alternative fuels and potential effect of suggested research methods. Using the suggested makes it possible to forecast the performance of a diesel engine working on liquid alternative fuels. The results of the research can be applied to developing new kinds and compositions of alternative fuels as well as to assessing necessary remodeling of diesel engines in their practical application.
