Methods and systems are provided for detecting hydrocarbon ingestion into an engine based on the simultaneous monitoring of cylinder imbalance and an elevated exhaust exotherm. Crankshaft acceleration data is monitored during steady-state and transient engine conditions while exhaust temperatures are estimated during non-regeneration conditions. Engine speed and load is limited to reduce further hydrocarbon ingestion.

Method and system for engine unburned hydrocarbon control

An internal combustion engine includes a head gasket positioned between a cylinder block and a cylinder head. The cylinder block has first and second cylinders separated by a block bore bridge, and a block cooling jacket with a first passage and a second passage intersecting a block deck face. The cylinder head has first and second chambers separated by a head bore bridge, and a head cooling jacket with a third passage and a fourth passage intersecting a head deck face. The gasket forms a slot positioned adjacent to at least one of the block bore bridge and the head bore bridge to fluidly connect the first and fourth passages to cool the at least one of the block bore bridge and head bore bridge.
