Question 1
A. Rotating components: BY applying proper grease on the components to make it more
slippery and smooth (Schelfaut, et. al, 2019).
B. Hot components: By applying a low-pressure grease gun on the hot components.
C. Engine oil: By placing it far from flammable items and use it only for oiling purpose.
D. High energy and charging system: Charging system needs a proper system of transmission.

Question 4
Component Function
Cylinder block Largest single part of the engine which is responsible for connecting all
other parts in a way or another.
Combustion
chamber
It is an enclosed space which is placed on the back part of the engine and
furnace.
Air-Fuel Ration
(AFR)
A mechanism consisting of valves, rocker arms, pushrods, litres and
camshaft used to control the amount of air and fuel entering the
combustion chamber.
Cylinder head It covers the internal system of the combustion system.
Axel-fuel mixture The component is responsible for letting air and fuel mixture into the
cylinder.
Gudgeon pins A pin containing piston rod which connecting together.
Piston and piston
rings
The component is responsible for sealing the combustion chamber to
prevent loss gases and regulating engine oil consumption.
Timing gear The timing gear is a tool which connects the chain
Reciprocating
motion
The component is responsible for converting the linear motion of the piston
into rotary motion of the crankshaft.
Valvetrain Component of the valve train that has the function of controlling the
opening and closing of the valve at the appropriate times.
Cylinder It is basically a power unit of an engine.
Piston and
connecting rod
Components are responsible for transferring force from expanding the gas
in the cylinder to the crankshaft via a connecting rod.
Exhaust valve The exhaust valve is placed at the top of the cylinder head.
Torsional Damper The component used to control torsional vibration in the crankshaft.
Gudgeon pins A pin holding a piston rod and connecting rod with each other.
Flywheel A mechanical device specifically designed to efficiently store rotational
energy and smooth out the flow of power.

Ports and reed
valves
Mainly used for the purpose of extending the performance of the two-
stroke engine.

Question 5
All the parts are interrelated to the transmission and gearbox. The interlinked of these parts can
bring more consistency.
10

Question 6
With the help of engine oil and hot grease, the engine can bring the high performance of engine
and consistency in the engine.
