“…These thermocouples were positioned in locations where, on the basis of earlier flow visualization studies, boiling is most likely to occur [4]. Eight thermocouples were embedded in each of the three instrumented cylinders.…”

“…Results of an earlier study that involved coolant flow visualization in a full-scale transparent model of the cylinder head were useful in estimating the coolant flow rate at each location in the cylinder head. Figure 2 details the flow in the valve bridge region as revealed by this study [4]. The coolant enters the "upstream" valve bridges, flows around the injector and through the "downstream" bridges.…”

An investigation aimed at identifying the heat transfer regimes present in the valve bridge coolasu passages of a diesel engine cylinder head is reported. An inverse heat conduction method utilizing experimental results along with a finite-element model was developed and applied. The sensitivity of lhe results 10 uncertain boundary conditions is discussed and found to be minimal. Locations where local boiling occurs were identified.

Oil-coolers are necessary components in high performance diesel engines. The heat removed by the cooler is a component in the total heat rejection via the engine coolant. Oil-cooler absorbs the heat rejected during the piston cooling and engine rubbing friction power loss. During flows of both coolant and engine oil via the oil-cooler, some flow resistances occur. The aim of the study is to determine values of the flow resistance coefficient for oil going through the cooler at various temperatures. The test stand was developed to determine time needed to empty tanks from liquids flowing through oil-cooler. The flow model was elaborated to study the mentioned flow resistance coefficient with respect to changing liquid temperature. The 20 °C increase in liquid temperature resulted in a flow resistance coefficient decrease of 30% for coolant and of the much more for engine oil. It was found that better results would be achieved with flows forced by means of pumps instead of using gravitational forces on the test stand.
