What
is the function on the following four stroke gasoline engine parts?
Intake Valves
The intake valve
is a valve that allows intake of fluids or air through an engine during the
engines operation. In cars this is known as the internal combustion combustion
engine. Intake valves creates room for the combustion of air and fuel.
Exhaust Valves
The
exhaust valves main function is to enable air in and out of the cylinders. The
incoming air is used to enable the ignition of the fuel which in turn drives
the pistons up and down.
Valve cover
A
valve cover is used to prevent oil leakage in the upper engine. It protects the
engine and the cylinder head from leaks of oil, water and any other fragments.
Intake Port
The
intake port is part of an automobile’s air intake system that is responsible
for managing the air required by the engine cylinders to operate.
Head
The head refers to
a fitting between the engine block and the piston cylinder. The head seals the
process of combustion and prevents the engine oil from mixing with the coolant
in the combustion chamber.
Coolant
The
primary function of the coolant is to remove the heat generated by the fuel
combustion in the engine block effectively. It also prevents corrosion to
engine components
Engine Block
The
engine block is essential for the internal combustion of an engine. It provides
the structure for attaching the cylindrical bored holes, the gaskets, valves
and seals.
Oil Pump
The
oil pump is used to pump and circulate the oil which protects the moving parts
of the engine and consequently increases the lifespan of the moving parts.
Oil Pan
The
primary function of the oil pan is to form part of the crankcase. It also
contains the engine oil prior and after circulation on the engine.
Oil Sump
Surrounds
the crankshaft and has an amount of oil which collects at the bottom.
Camshaft
Controls the closing
and opening of the exhaust and intake valves in the cylinder head either in a
direct way via rocker arms, push rods and followers. Therefore, it depicts the
power characteristics of an engine.
Rocker Arm & Spring
Rocker
arms are mounted on a shaft to provide oscillation around a certain point. Its
function is to provide control of the opening and closing of the valves at
specific instant of the cycle that is correct.
Spark Plug
Supplies
spark plug that in turn ignites combustion of the air and the fuel. Proper
timing of the spark is essential for proper combustion.
Exhaust Port
Combusted
gases are moved to a central collection unit known as the collector via the
exhaust port. The basic function of the exhaust port is to move used gases.
Piston
This
is a cylindrical in shape metal that moves up and down in the cylinder
Connecting Rod
It connects the crankshaft and the
piston. Due to changes of the piston, the rod can rotate at both ends to
resemble the movements of the piston.
Overhead camshaft
Responsible
for placing the camshaft of an internal combustion engine within the cylinder
heads. It also drives the valves in a direct manner.
Crankshaft
Responsible
for turning the piston’s in an up and down motion to resemble the movement of
the crank.
