The identification of PM parameters in compression ignition engines


Keywords: , ,

The paper discusses the possibility of a synthetic approach to the parameters of PM generated by Diesel engines. The authors felt compelled to realize the task following the obtainment of positive results of the PM parameters research under different operating conditions of combustion engines. The continuation of the topic is a new approach towards the use of the values characterizing engine operation and vehicle driving conditions for the identification of the PM parameters in compression ignition engines. For the description of the engine and vehicle operating conditions time density characteristics have been used that combined the engine speed and engine load (or the vehicle speed and acceleration) with its operating time under such conditions. The result of the actions is a proposal of a mathematical model that describes the basic properties of the PM (their mass, number and diameter) under different engine operating conditions (stationary and dynamic). The proposed mathematical models, including the experiment planning, that served to identify the PM in terms of their mass, number and diameter, have been developed based on the results of the emission measurement and engine parameters under stationary and dynamic conditions.
