文摘

Laser plasma ignition is applied to a direct injection Diesel spray, compared with auto-ignition. Critical local fuel/air ratio for LIP provoked ignition is obtained. The LIP system is able to stabilize Diesel combustion compared to auto-ignition cases. Varying LIP position along spray axis directly affects Ignition-delay. Premixed combustion is reduced both by varying position and delay of the LIP ignition system.
