An innovative ignition system was evaluated for its suitability for EGR-diluted GDI engine. The energy measurements showed the ultra-high power ignition system could provide about 12 kW power and generated a strong shock wave captured by a high-speed photography. The 2000 r/min@0.44 MPa BMEP engine test showed a 10% EGR ratio limit extension and the enhanced flame kernel and flame propagation helped to raise the thermal efficiency by 5.5% relatively.
