Gasoline Engine Performance with Laser-Induced Breakdown Ignition

Abstract

Laser-induced ignition offers the potential benefit of improved internal-combustion engine performance compared with conventional spark ignition. Since the ignition point can be chosen arbitrarily, laser ignition is non-intrusive, and heat loss and radical quenching at the wall can be reduced. In this report, the results of laser-ignition experiments on gasolineengine performance under lean-burn and high-dilution conditions are introduced, along with the results of multi-point laserignition experiments.
