Laser Ignition (LI) is a new, innovative technology which overcomes several limitations of conventional spark ignition; it presents many potential advantages for engine dynamic control, especially for Gasoline Direct Injection (GDI) Engine. This paper highlights a new approach, using Principal Component Analysis (PCA) of the Pressure Curve, to dynamically control Multiple Pulse Laser Ignition (MPLI); and reports on the effectiveness of Multiple Pulse Laser Ignition (MPLI) in lean combustion. Experimental test data is presented; and these results indicate how the control of MPLI improves the performance of the engine. This work is part of an EPSRC funded research project which is to investigate how optimized control strategies, including multiple stratified fuel injection (MSFI); MPLI and Multiple Positions Laser Ignition (MPsLI), can help to improve the stability of leaner operation and reduce the emissions. The possible future of LI dynamical control strategies (DCS) is discussed.
