On which cycle does marine diesel engine work? Explain the cycle.

THEORETICAL HEAT CYCLE

Marine diesel engine works on dual combustion cycle.

DUAL COMBUSTION CYCLE : The behaviour of many slow-speed engines is more correctly represented by a mixed-cycle or dual-cycle. This was achieved by the “blast injection principle”. Today, diesel (HFO for marine engines) is universally used for reciprocating engines in which heat as induced by the compressed air in the cylinder, ignites a finely atomized spray of fuel. Thus, the theoretical cycle on which modern diesel engine works is presented by the dual cycle illustrated in the diagram below:
