Description

In the diesel engine, pre-injection carried out just before the main injection was effective in combustion noise reduction. On the other hand, the pre-injection spray can affect the smoke emission through the interaction with the main injection spray. Therefore, the spray to spray interaction and smoke emission were analyzed by simultaneous visualizing of the spray drops and smoke with laser extinction method.
