Introduction
Combustion is a chemical reaction in which certain elements of the fuel like
hydrogen and carbon combine with oxygen liberating heat energy and
causing an increase in temperature of the gases.

The Operational Amplifier
Usually Called Op Amps
An amplifier is a device that accepts a varying input signal and
produces a similar output signal with a larger amplitude.
Usually connected so part of the output is fed back to the input.

Why do we study about Fuel for IC Engine?
Because fuel properties affect the combustion process in engine
and its operation
Engines are designed to run on fuels that meet certain standards
