• SPARK PLUG
• FUEL TANK
• STARTER
INTRODUCTION
• A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes
a power cycle with two strokes (up and down movements) of the piston during one power cycle,
this power cycle being completed in one revolution of the crankshaft. A four-stroke
engine requires four strokes of the piston to complete a power cycle during two crankshaft
revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the
compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions
occurring at the same time.
• Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow
range of rotational speeds called the power band. Two-stroke engines have fewer moving
parts than four-stroke engines.
TWO STROKE ENGINE
• A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that
completes a power cycle with two strokes (up and down movements) of the piston
during one power cycle, this power cycle being completed in one revolution of the
crankshaft
WORKING PRINCIPLE
• Overall, a two-stroke engine contains two processes: Compression stroke:
The inlet port opens, the air-fuel mixture enters the chamber, and the piston
moves upwards compressing this mixture. A spark plug ignites the
compressed fuel and begins the power stroke
CARBURETTOR
• A carburetor or carburettor is a device
that mixes air and fuel for internal
combustion engines in an appropriate
air–fuel ratio for combustion. The term
is sometimes colloquially shortened to
carb in the UK and North America or to
carby in Australia
WORKING PRINCIPLE
• The carburetor works on Bernoulli's principle: the faster air moves, the
lower its static pressure, and higher the dynamic pressure is. ... The speed of
this flow, and therefore its (static) pressure, determines the amount of fuel
drawn into the airstream
SPARK PLUG
• A spark plug (sometimes, in British
English, a sparking plug, and,
colloquially, a plug) is a device for
delivering electric current from
an ignition system to the combustion
chamber of a spark-ignition engine to
ignite the compressed fuel/air mixture by
an electric spark, while containing
combustion pressure within the engine.
WORKING PRINCIPLE
• A spark plug is an electrical device that fits into the cylinder head of some
internal combustion engines and ignites compressed aerosol gasoline by means
of an electric spark. Spark plugs have an insulated centre electrode connected
by a heavily insulated wire to an ignition coil or magneto circuit on the outside,
forming, with a grounded terminal on the base of the plug, a spark gap inside
the cylinder.
• The spark plug has two primary functions:
• (1) To ignite the air/fuel mixture
• (2) To remove heat from the combustion chamber
FUEL TANK
• A fuel tank (also called a petrol tank or
gas tank) is a safe container for
flammable fluids. Though any storage
tank for fuel may be so called, the term is
typically applied to part of an engine
system in which the fuel is stored and
propelled (fuel pump) or released
(pressurized gas) into an engine
WORKING PRINCIPLE
• The engine functions the same way as a gasoline engine. Natural gas is stored
in a fuel tank, or cylinder, typically at the back of the vehicle. ... Finally, the
fuel is introduced into the intake manifold or combustion chamber, where it is
mixed with air and then compressed and ignited by a spark plug
STARTER
• A starter (also self-starter, cranking
motor, or starter motor) is a device used
to rotate (crank) an internal-combustion
engine so as to initiate the engine's
operation under its own power. Starters
can be electric, pneumatic, or hydraulic.
The starter can also be another internal-
combustion engine in the case, for
instance, of very large engines, or diesel
engines in agricultural or excavation
applications
WORKING PRINCIPLE
• The starter works on the fact that the torque is
proportional to the square of the starting
current, which in turn is proportional to the
applied voltage. Thus, the torque and the
current can be adjusted by reducing the voltage
at the time of starting the motor. ... This is also
known as Time Voltage Ramp System.
