The document discusses the basic components and functions of a 4-stroke internal combustion engine. It explains that a 4-stroke engine converts gasoline into motion through four processes: intake, compression, combustion, and exhaust. During intake, the cylinder fills with an air-fuel mixture. In compression, this mixture is compressed to make it more combustible. Combustion ignites the compressed mixture, creating motion. Finally, exhaust releases the exhaust gases from the cylinder.

one form of energy into the other
form.
3. Heat engine is a modified form of engine
used for transforming chemical energy of
fuel into thermal energy and
subsequently for producing work.
