- Task 04 The spark ignition engine It is assuming to be operating on the ideal air standard (Otto) cycle. This four-cyliner engine has a swept volume of 1.5 litres and the clearance volume in each cylinder is 135 cm3. The inlet temperature of the air is 27 0C, and the maximum cycle temperature is 1965 0C . using the available information determine the relative efficiency Having determined the above efficiencies, you should review these efficiencies by comparing them with each other and comparing values with published efficiency data for these types of heat engines.Ignition delay can be considered as the duration between the start of injection and startof combustion in diesel engines.• Starting from the injection of the fuel spray, explain the events happening(physical and chemical) in the ignition delay phase. • Explain the advantage of using pilot injection in terms of diesel knockingEngine knocking is defined as self-ignition of unburnt mixture other than the spark plugpoint. Explain the engine structural parameters’ effects on engine knocking.

- (a) With the neat diagram of the Gas turbine sketch all the internal parts of the typical gas turbine used for the Electricity production. (b). List at least 8 different accessories or other important components which must be used along with gas turbine for good operation of the gas turbine. (Note :- You include the Gas turbine cooling system, Noise control system, Air filter system, Exhaust gas management or any other electrical controls to support your answer)Technician A says that during oxidation, as NOx gases pass over the catalyst, the N atoms are pulled from the NOx molecules and are absorbed by the catalyst. The released oxygen atoms then flow through the converter to the second bed. The result of NOx oxidation is pure nitrogen plus oxygen or carbon dioxide. Technician B says that during the reduction phase inside the converter, hydrocarbon and carbon monoxide molecules experience a second combustion. The result of this combustion or oxidation process is water vapor and carbon dioxide. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor BAB power engineering 1.) Illustrate the different parts of the cooling system of an internal combustion engine
