Read the text and do the tasksEngine Components Cylinder: It is the space in which the piston makes a reciprocating motion. The varying volume created in the cylinder during the operation of the engine is filled with the working fluid and subjected to different thermodynamic processes.Piston: It is a cylindrical component fitted into the cylinder forming the
moving boundary of the combustion system. It fits perfectly into the cylinder providing a gas-tight space with the piston rings and the lubricant. It
forms the first link in transmitting the gas forces to the output shaft.Combustion Chamber: The
space enclosed in the upper
part of the cylinder, by the cylinder head and the piston top
during the combustion process,
is called the combustion clamber. The combustion of fuel
and the consequent release of
thermal energy results in the
building up of pressure in this
part of the cylinder.Inlet Manifold: The pipe
which connects the intake system to the inlet valve of the
engine and through which air
or air-fuel mixture is drawn
into the cylinder is called the
inlet manifold.Exhaust Manifold: The pipe which connects the exhaust system to the
exhaust valve of the engine and through which the products of combustion
escape into the atmosphere is called the exhaust manifold.Inlet and Exhaust Valves: They are provided either on the cylinder
head or on the side of the cylinder for regulating the charge coming into the
cylinder (inlet valve) and for discharging the products of combustion (exhaust valve) from the cylinder. Spark Plug: It is a component to initiate the combustion process in
spark ignition engines and is usually located on the cylinder head.Connecting Rod: It interconnects the piston and the crankshaft and
transmits the gas forces from the piston to the crankshaft.Crankshaft: It converts the reciprocating motion of the piston into useful rotary motion of the output shaft. The crankshaft is enclosed in a crankcase.Piston Rings: Piston rings, fitted into the slots around the piston, provide a tight seal between the piston and the cylinder wall thus preventing
leakage of combustion gases.Gudgeon Pin: It forms the link between the small end of the connecting
rod and the piston. Camshaft: The camshaft and its associated parts control the opening and
closing of the two valves. This shaft also provides the drive to the ignition
system. The camshaft is driven by the crankshaft through timing gears. Cams: These are made as integral parts of the camshaft and are designed
in such a way to open the valves at the correct timing and to keep them open
for the necessary duration.Flywheel: The net torque imparted to the crankshaft during one complete cycle of operation of the engine fluctuates causing a change in the
angular velocity of the shaft. In order to achieve a uniform torque an inertia
mass in the form of a wheel is attached to the output shaft and this wheel is
called the flywheel. The variation of net torque decreases with increase in
the number of cylinders in the engine and thereby the size of the flywheel
also becomes smaller. This means that a single cylinder engine will have a
larger flywheel whereas a multi-cylinder engine will have a smaller flywheel.Are the statements true or false?1. The piston moves in a circular motion within the cylinder.
