Methods for Assessing the Thermodynamic Characteristics of the Combustion Process Using the Indicator Diagram in Spark-Ignition Engines

摘要

The paper deals with the evaluation of the thermodynamic characteristics of the combustion process according to the experimentally obtained indicator diagram of pressure in spark ignition engines.The proposed method allows to determine the main characteristics of the combustion process(change in internal energy,heat generation characteristic,speed and intensity of combustion processes in the flame front,volume of the burned mixture,volume of unburned mixture)using the experimental indicator diagram of pressure obtained for a spark ignition engine.
