Question 45Motor Plants - Assistant Engineer

The correct answer is B) Diesel. The diagram MO-0036 illustrates the Diesel cycle, which is characterized by the compression of air and the subsequent injection of fuel at the point of maximum compression. This results in the fuel-air mixture being ignited by the high temperature and pressure of the compressed air, rather than by an external ignition source as in the Otto cycle. The other options are incorrect because the Otto cycle uses an external ignition source, the Gas Turbine cycle uses continuous combustion, and the Rankine cycle is a thermodynamic cycle used in steam power plants, not internal combustion engines.
