Multiple pulse laser ignition in GDI lean combustion

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 engine. This paper highlights a new approach, using principle component analysis of the pressure curve, to dynamically control multiple pulse laser ignition (MPLI). In the results, experimental data presents how the control of MPLI improves the performance of the engine and demonstrates the effectiveness of MPLI in lean combustion. This work is part of an Engineering and Physical Sciences Research Council funded research project which is to investigate how optimised control strategies, including multiple stratified fuel injection (MSFI); MPLI and multiple location laser ignition (MLLI), can help to improve the stability of leaner operation and reduce the emissions. The possible future of LI dynamical control strategies is discussed.
