One of the most powerful engines in the world, the Wartsila-Sulzer RTA96, is yuuuge! The gargantuan 2-stroke diesel engine is almost the width of an American football field and about 4 stories high. This engine powers one of the largest container ships in the history of mankind, the Emma Maersk. Useful Specs for analysis of the Wartsila-Sulzer RTA96 diesel engine: cylinder bore: 96 cm cylinder stroke: 2.5 m! maximum cylinder volume: 1.86 m a. What is minimum cylinder volume, the displacement volume and compression ratio? b. The engine is designed to operate with surroundings at STP conditions with a cutoff ratio of 3 for the cycle. Model the cycle as an ideal Diesel cycle with the cold air standard and create a table listing the pressure, temperature and volume (extensive) for the working fluid at each stage. The Wartsila-Sulzer is a 2-stroke engine. number of cylinders: 14 nominal RPM: 102 c. What is the extensive work output per cylinder during combustion (using our model assumptions)? d. What the mass of the working fluid per cylinder (using our model assumptions)? e. What is the extensive heat input per cylinder during combustion per cylinder? f. The energy density of diesel fuel is 48,000 kJ/kg. What is the mass of diesel required to supply the heat input for one cycle per cylinder of the Wartsila-Sulzer RTA96? g. What is the rate of heat input to the whole engine at the nominal RPM if the combustion process occurs once per cycle, there are 2 strokes per cycle and 2 strokes per revolution? h. What is the mass of diesel fuel required to run the entire Wartsila-Sulzer RTA96 engine at the nominal RPM for 1 hour (using the above assumptions)? i. What is the extensive heat rejection per cylinder per cycle? j. What is the net work output per cylinder per cycle? k. What is the thermal efficiency for the Wartsila-Sulzer RTA96 engine? 1. What is the power output for the entire Wartsila-Sulzer RTA96 engine at the nominal RPM if there is 1 power stroke per cycle, 2 strokes per cycle and 2 strokes per revolution?
