The characteristics of gasoline spray after wall impingement from a high-pressure gasoline direct injection injector were investigated. To examine the effects of various factors on the impingement development, experiments were conducted at different injection pressures, ambient pressures, wall distances and angles. The impinging spray development, spray height, spray radius, and spray growth rate were measured. Experimental results show that the spray penetration increases with the increase of injection pressure, wall distance and angle. The penetration decreases with the increase of ambient pressure. High injection pressure and low ambient pressure increased the fuel contact area and accelerated the evaporation. The predicted penetrations with the empirical equations in all cases agree with measurements, to a certain extent.
