Abstract
A GDCI engine control system includes a fast electric heater located within a pocket in a cylinder head. The pocket is in fluid communication with multiple intake ports. A heater control system includes a capacitor that is configured to provide a voltage that is greater than battery voltage to more quickly heat the intake air during a cold start. Subsequently a lower voltage can be supplied to the heater.
