Abstract: Spark plugs are disclosed that include electrode arrangements to improve the charge flow into and out of the annular volume around the insulator nose and a pre-chamber volume of a pre-chamber device, thus directing a purge of exhaust gases trapped in the annular volume to a space formed by the exterior of the spark plug body and the interior of the pre-chamber device.

Abstract: Control of an internal combustion engine system in response to a condensation condition associated with a charge air cooler is disclosed. One or more operating parameters of the internal combustion engine are monitored to the control charge air cooler coolant inlet temperature to keep the charge temperature above the estimated dew point to reduce or prevent condensation upstream of the intake manifold.
