Components

Question 1

Piston

Answer 1

Converts the energy released during the combustion process into mechanical work

Question 2

Connecting rod

Answer 2

Transmits power and convert the linear motion of the piston into rotational motion of the crankshaft

Question 3

Crankshaft

Answer 3

Converts the reciprocating (up and down) motion of the pistons into rotational motion

Question 4

Gears

Answer 4

Used to transmit power and allow for a range of engine speeds and torque levels

Question 5

Camshaft

Answer 5

Precisely controls the opening and closing of the intake and exhaust valves

Question 6

Cylinder Head

Answer 6

The main task of the cylinder head is to close the combustion chamber of the engine from the top

Question 7

Fuel pump

Answer 7

Delivers fuel from the fuel tank to the engine’s fuel injectors, ensuring a consistent and reliable supply for combustion

Question 8

Rocker gear

Answer 8

Transfers the camshaft’s rotational motion into the linear motion needed to open and close the engine’s intake and exhaust valves

Question 9

Tappets

Answer 9

Commands the movement of the engine valves by limiting the gap between the camshaft and the valves

Question 10

Push rods

Answer 10

Transfers the motion from the camshaft to open and close the valves at the right time

Question 11

Turbocharger

Answer 11

Increases an engine’s power output and efficiency by forcing more air into the cylinders

Question 12

Air-manifold

Answer 12

Distributes air evenly to each cylinder, ensuring each cylinder receives the proper amount of air for combustion

Question 13

Exhaust manifold

Answer 13

Collects exhaust gases from each cylinder of the engine and directs them through a single outlet

Question 14

Air filter

Answer 14

Traps and filters out contaminants such as dirt or debris before they can enter the engine

Question 15

Main bearings

Answer 15

Holds the crankshaft in place and allows it to rotate within the engine block

Question 16

Bottom ends

Answer 16

The components located within the engine block, specifically the crankshaft, connecting rods, and pistons

Question 17

Gudgeon

Answer 17

Connects the piston to the connecting rod, and provides a bearing for the connecting rod to pivot upon as the piston moves

Question 18

Flywheel

Answer 18

To store and smooth out the power output of the engine

Question 19

Bedplate

Answer 19

Acts as the foundation, supporting the engine block, crankshaft, and other internal components, ensuring they remain in the correct position and alignment

Question 20

A-Frame

Answer 20

Provides support and stability for the engine’s main bearings

Question 21

Cylinder Block

Answer 21

Serves as the structural foundation for the engine, housing the cylinders and their components, and supporting the crankshaft

Question 22

Tie rods

Answer 22

Structural integrity and vibration control

Question 23

Crosshead

Answer 23

Converts the rotating motion of the crankshaft into the linear motion required to move the piston and piston rod up and down within the cylinder liner

Question 24

Shaft bearings

Answer 24

Reduces friction and wear between rotating parts, like the crankshaft and camshaft, and their supporting structures

Question 25

Thrust Block

Answer 25

Transfers forward or astern propeller thrust to the hull and limits axial movement of the shaft

Question 26

Reduction gearing

Answer 26

Decrease the rotational speed of an engine while increasing its torque

Question 27

Clutches

Answer 27

To engage and disengage the power transmission between the engine and the gearbox
