The characteristics of the ambient gas entrainment into an evaporating diesel spray were analyzed by using the results of the distributions of fuel vapor concentration and droplets density, which were measured by the new technique developed in this study. It was found that the characteristics of the ambient gas entrainment was strongly affected by the ambient gas temperature and impingement distance. The total mass of the ambient gas entrained into the evaporating spray impinging on a flat wall was grater than that of the free spray at the same time from when the injection started. In the case of the impinging spray, the optimum impinging distance exists for facilitating the entrainment of the ambient gas.
