  • To explain modern developments in IC engines

16.1 Introduction

In the previous chapter, we studied vapour power cycles, particularly Rankine cycle and its modifications. The working fluid considered was a vapour which underwent a phase change during the cycle of operation. Also, in the Rankine heat engine, heat was supplied from the surroundings during one part of the cycle and rejected ...
