Integrated Ionization Control System

Ionization systems utilize the ignition coil as both an actuator for ignition and a sensor for measuring the ionization current across the spark plug gap in every cylinder to continuously monitor and interpret the quality of combustion.

Visteon's Integrated Ionization Control System integrates electronics into the ignition coil. This unique solution delivers a cost-effective approach to ionization and signal-to-noise ratio comparable to an instrument grade device. The exceptional signal-to-noise ratio is essential to enabling full range inaudible knock detection and for running continuous closed loop spark control. Visteon proprietary algorithms ensure maximum benefit is drawn from interpretation of the signal.

Benefits

• Reduces complexity by combining multiple sensors and signals into a single system that combines knock, misfire and cylinder identification sensing with ignition coil functionality.
• Improves reliability, serviceability and warranty by offering full range OBD II compliance for misfire, including partial burn algorithms to avoid misdiagnosis.
• Increases torque and fuel economy through continuous operation (at borderline knock) for high compression ratio engines.
• Reduces variability cylinder-to-cylinder, engine-to-engine, and over time for higher long-term reliability and emissions performance.
