It is important to note that although some cycles have a typical combustion location (internal or external), they often can be implemented with the other. For example, John Ericsson developed an external heated engine running on a cycle very much like the earlier Diesel cycle. In addition, externally heated engines can often be implemented in open or closed cycles. In a closed cycle the working fluid is retained within the engine at the completion of the cycle whereas is an open … main financial bankWebQ L equals the amount of heat transferred between the device (heat engines, refrigerators, and heat pumps) and a thermal reservoir of low temperature T L.
