KIT-Kalaignarkarunanidhi Institute of Technology: Continuous Internal Assessment (CIA)

This document is a test for a Continuous Internal Assessment (CIA) in the course Internal Combustion Engines. It contains two parts - Part A with 7 short answer questions worth 2 marks each and Part B with 3 long answer questions worth 12 marks each. Part A questions assess different concepts related to IC engines like types, operation of 2-stroke and 4-stroke engines, fuel properties, stoichiometric ratio and knocking. Part B questions require explaining in detail the working principles of 2-stroke and 4-stroke engines, fuel properties, and construction and working of a Solex carburetor or fuel injection systems in SI engines. The test aims to evaluate students' understanding of key concepts and principles of internal combustion
