Abstract
Multiple-injection strategy widely used in modern diesel engines can control the in-cylinder mixing process and adjust the combustion process to fit the engine operating conditions. This study uses a one-dimensional spray model with improved injection velocity calculation and determination of spray tip to simulate the diesel spray with multiple-injection. Then the calculated spray penetrations are compared to the experimental data to validate the developed spray model. Analysis is performed on mixing process of diesel spray with multiple-injection using entrainment rate, equivalence ratio, velocity over cross-section, with the spray-to-spray interaction revealed and the entrainment wave effects on spray-to-spray interaction discussed.
