Fuel Injection Strategy for Internal Combustion Engine Having Dedicated EGR Cylinders

A method using exhaust gas recirculation (EGR) in an internal combustion engine. The engine has at least one “dedicated EGR cylinder”, whose entire exhaust is recirculated back to all the engine cylinders.

This post injection method overcomes flammability limits of a dedicated EGR cylinder, and increases the hydrogen (H2) and carbon monoxide (CO) in its exhaust.

Ignition control system for internal combustion engine and ignition control method

This ignition device for an internal combustion engine (1) has an overlap voltage generation circuit (47) which, after the start of discharge by a secondary coil, applies a discharge voltage and an overlap voltage of the same direction between the electrodes of an ignition plug (29) and continues a discharge current, and creates overlap discharge in an overlap discharge region corresponding to a high exhaust gas recirculation rate. When the engine load decreases and moves from the overlap discharge region with high exhaust gas recirculation rate to an overlap discharge stopping region with low exhaust gas recirculation rate, a delay period ΔT is provided for stopping the overlap discharge. After an exhaust recirculation control valve closes, the exhaust gas recirculation rate temporarily increases due to the decrease in fresh air, but misfires can be prevented since the overlap discharge is continued during the delay period ΔT.
