Question: A 1500 cc IC engine working on a 4-stroke Otto cycle has a compression ratio of 11. Estimate the efficiency, peak pressure, and peak temperature

A 1500 cc IC engine working on a 4-stroke Otto cycle has a compression ratio of 11. Estimate the efficiency, peak pressure, and peak temperature if the output is 40 kW when running at 3000 rpm. If the engine is to run on a Diesel cycle, estimate the compression ratio, cut off ratio, efficiency, and output at 3000 rpm when peak pressure and peak temperature remains the same. (Ambient pressure and temperature are: 1 bar and 300 K respectively.)
