Description
What is Engine? What are Types of Heat Engines?
Definition of Engine:
Any device which converts energy from one form to another is known
as engine. Energy is in various forms like mechanical energy,
chemical energy, wind energy, flow energy, electric energy,
magnetic energy, sound energy, light energy etc.
Energy can be convert from one form to another (First law of
Thermodynamic).
Any device which convert chemical energy of fuel into thermal
energy and convert this thermal energy into mechanical energy,
known as heat engine. All automobiles engines, gas turbine engines,
steam turbine engines etc. are heat engine. We will focus only on
heat engines on this website.
Basic Types of heat Engines:
Mainly there are two types of heat engines. The first one is known
as Internal Combustion Engine (IC Engine) and the other one is
known as External Combustion Engine (EC Engine).There engines are
further classified into reciprocating engine and rotary engine.
Internal Combustion Engine:
An engine in which combustion of fuel (Burning of Fuel or
converting of chemical energy of fuel into thermal energy) take
place into a closed cylinder is known as internal combustion
engine. All automobile engines are internal combustion engine.
These engines have higher thermal efficiency low weight to power
ratio.
These engines are further classified into Rotary Engine (Wankel
engine) and Reciprocating Engine (Diesel and Petrol Engine).
Reciprocating internal combustion engines are used in automobiles,
motor cycles, boat, slow speed aircraft etc.
Engine parts
Pushrod
Pushrod is used when the camshaft is situated at the bottom end of
cylinder.
It carries the camshaft motion to the valves which are situated at
the cylinder head.
Main Parts of an Internal Combustion Engine (pushrod)
Flywheel
A flywheel is secured on the crankshaft. The main function of
flywheel is to rotate the shaft during preparatory stroke. It also
makes crankshaft rotation more uniform.
