This document provides an overview of internal combustion engines, including their introduction, working, nomenclature, cam mechanisms, classifications based on strokes, fuel, ignition systems, cylinders, applications, advantages, and disadvantages. Key classifications discussed include two-stroke vs four-stroke engines and spark ignition vs compression ignition engines. Applications mentioned include use in transport vehicles, prime movers, agriculture machinery, and earth moving equipment. Advantages include simplicity and lower costs, while disadvantages include lower cooling rates and need for water maintenance in water-cooled engines.
