ASSIGNMENT 1

Students are asked to complete the below listed questions and submit on or before 13.09.2024. 1. Explain in details about the construction and working principle of SI engine with neat sketch. 2. Distinguish between two and four stroke engines. 3. A single-cylinder, four-stroke engine has a cylinder bore of 0.1 meters and a stroke length of 0.12 meters. The engine operates at 3000 RPM with an average effective pressure of 800 kPa. Calculate the indicated power of the engine. 4. An engine has an indicated power of 75 kW. It consumes fuel at a rate of 0.015 kg/s, and the fuel has a calorific value of 44,000 kJ/kg. Calculate the indicated thermal efficiency of the engine.

Combustion, Combustion camber Design, Emissio

1. Demonstrate the combustion process in spark ignition and compression ignition engines. 2. Explain the design differences and significance of combustion chambers in diesel engines. 3. Apply the principle of exhaust gas recirculation and its effectiveness in reducing exhaust emissions in both SI and CI engines. 4. Apply the role of three way catalytic converter in an internal combustion engine emission control with a neat diagram and discuss the chemical reactions that occur within the converter. 5. Elaborate the BS VI and euro emission norms in details.
