COOLING SYSTEM AND METHOD OF COOLING AN INTERNAL COMBUSTION ENGINE WITH EGR DISCHARGE

摘要

"cooling system for an internal combustion engine with exhaust gas recirculation (egr)". The present invention relates to a refrigeration system that pumps refrigerant through parallel connections to a crankcase and an egr chiller in an exhaust gas recirculation (egr) internal combustion engine. A crankcase supply duct connects a refrigerant pump to a refrigerant channel formed by the crankcase. The refrigerant channel is connected to a refrigerant chamber formed by the cylinder head. an egr chiller supply duct connects the egr chiller to the refrigerant pump. The egr chiller is connected to the refrigerant chamber. refrigerant flows from the refrigerant pump into the crankcase supply duct and into the chiller supply duct egr at essentially the same time and at essentially the same temperature. refrigerant circulates from the refrigerant pump through the refrigerant channel and into the refrigerant chamber. refrigerant circulates from the refrigerant pump through the egr cooler into the refrigerant chamber. the refrigerant returns to the refrigerant pump from the refrigerant chamber in the cylinder head.
