Abstract

At present, there is no theoretical equation for quantitatively calculating gas exchange losses of an internal combustion engine. In order to accurately research on change rules of the gas exchange losses during the working process of internal combustion engines, the equation for quantitative calculating the gas exchange losses should be established. This work presents a concept of Newtonian ideal airflow and an energy equation for the Newtonian ideal airflow, based on theoretical analysis. Experimental researches were also conducted by employing a LJ491QE1 gasoline engine and the gas exchange losses of the engine were calculated quantitatively by using the energy equation for Newtonian ideal airflow. The results shows that the intake loss power of the naturally aspirated port fuel injection gasoline engine make up a higher percentage of its effective output power under low load engine operating states, and the exhaust loss power of the engine make up a higher percentage of its effective output power under high load engine operating states. The theory for calculating the gas exchange losses quantitatively presented in this paper has important meaning to further research on the actual circulation loss of the internal combustion engines.
