The Otto Cycle
Objective: To provide
information of the Otto
cycle, examples, and
applications
Johnny Lee
What is it?
• A cycle involving the
conversion of energy created
by the combustion of an
explosive gas to mechanical
energy
• A 4 stroke cycle involving the
suction of an explosive gas,
compression, ignition, and
expulsion of products from the
combustion
