More Information
Summary:A hybrid cooling system for an engine is provided. The system comprises a block oil cooling circuit, a head coolant cooling circuit, the head and block circuits having a common heat exchanger. The system also includes a flow device in the head cooling circuit for preventing coolant flow in the head cooling circuit at least during a first phase of a warm-up phase of the internal combustion engine, a delivery device in the block cooling circuit which delivers engine oil constantly under pressure through the block cooling circuit to bearing points in a cylinder block and to bearing points in a cylinder head, and a control element arranged in a control line to reduce the delivery capacity of the delivery device through the block cooling circuit at least during the first phase of the warm-up phase. In this way, heat transfer in the common heat exchanger may be substantially prevented.
