ACIS uses a high-energy, high frequency electrical field to produce repeatable, controlled ionization, creating multiple streams of ions to ignite the fuel mixture throughout the combustion chamber. Conventional spark ignition creates only a small arc in the gap between the electrodes of a spark plug.Optimized for ease of implementation, the two-piece igniter architecture allows engine manufacturers to replace traditional coil and plug systems with no adverse impact on engine design or assembly.This advanced system technology:Enables advanced combustion strategies leading to fuel economyCO2 improvements higher than 10% over a wide speed load rangeLarger ignition source: Multiple 25 mm long streamers vs. single 1 mm arc in sparkHigher dilution (EGR) tolerance: 35% vs. 25%Extended lean limit combustion stability = 1.8 vs. 1.5Robust combustion initiated in as little as 30 sFaster burnless delay: 5 less ignition advance than sparkEnhances HCCI capabilityAdvanced controls (Ignition Optimization System) to enable consistent corona operation through entire speed-load rangeCompatible with existing gasoline engine architecturesProven materials and design strategies to speed readiness for volume productionPatent pending
