Numerical Study on the Flow Characteristics in Coolant Passage of the Homogeneous Charge Compression Ignition Engine

摘要

The characteristics of pressure drop and cooling performance of coolant passing through surroundings of each cylinder have been studied on a linear 4-cylinder 4-valve 2 liter diesel engine using a commercial CFD code. The results on coolant flow rate per gasket hole show that the 48% of total coolant flow rate flows through exhaust port regions while the remaining 52% flows through intake port regions.
