Processes dynamic characteristics in the intake system of piston internal combustion engine

Abstract

The experimental studies of gas dynamic and heat exchange characteristics of processes in the intake system were carried out on the full-scale model of a piston engine. The experimental setup and the instrumentation and measurement base for this study are briefly described. The experimental data on the dynamics of changes in airflow velocity and instantaneous local heat transfer in the intake system of a piston engine are presented in the article. The amplitude–frequency analysis of the considered flow parameters is carried out. It is shown that the intensity of local heat transfer in the intake system in a pulsating flow is much lower than for a stationary flow, and this difference reaches 2.5 times.
