Abstract

Despite significant achievements in the diesel engines starting characteristics improvement, there are still problems associated with unstable ignition, poor combustion of fuel during start-up and subsequent warm-up. For the conditions of a diesel engine’s cold start, the characteristics of the fuel burnout, heat generation, and thermal management are determined. The inaccuracy in the cylinder pressure measuring was calculated. The patterns of fuel burnup, obtained on the basis of the experimental pressure diagrams analysis, make it possible to obtain a good agreement between the calculated and experimental results. The influence of the start-up conditions, including the increase in the intake air temperature, on the magnitude of the kinetic indicators of combustion characteristics and the completeness of combustion of fuel is established.
