The diesel engine was invented during the industrial revolution by a German engineer. Rudolf Diesel grew up in France but then left for England during the Franco-German war. ... By studying thermodynamics, Diesel found he could make a smaller, internal combustion engine that would convert all heat into work.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
3. BRIEF INTRODUCTION
• A diesel engine is an internal combustion
engine.
• It converts gasoline into motion
• It is the most common car engine type
• It is relatively efficient
• It is relatively inexpensive
• The engine works on the principle
of diesel cycle
4. HISTORY
Rudolf Christian Karl Diesel (March 18,
1858 – September 29, 1913) was a
German inventor and mechanical engineer,
famous for the invention of the 4-stroke diesel
engine.
RUDOLPH DIESEL
5. Working of Four Stroke Diesel Engine
Following are the four strokes:-
1 – Intake/Suction stroke
2 – Compression stroke
3 – Expansion stroke
4 – Exhaust stroke
6. 1. Intake Stroke
In suction stroke piston starts at Top
Dead Center (TDC) of the cylinder and
moves to the Bottom Dead Center
(BDC).
Outlet valve will be closed
and inlet valve will be open to allowing
the fresh charge of mixed fuel & air
into the cylinder.
7. 2 . Compression stroke
In compression stroke, Once piston
reaches BDC & moves back TDC, inlet
valve will be closed. As the piston
moves towards TDC. It compress air
inside the cylinder & compression takes
place. Hence it is called compression
stroke.
8. 3. Power Stroke
In expansion stroke, Both the valves
are closed. When piston reaches top
of its stroke. the fuel is sprinkled by
the Fuel Injector and the fuel mixture
is ignited due to high temperature &
pressure generated inside the cylinder
& push down the piston to BDC.
Hence it is known as Power or
expansion stroke. The Power
generated in this stroke is stored in
the flywheel for its furthur utilisation
in the other strokes.
9. 4. Exhaust stroke
In this stroke exhaust valve is opened
when piston reaches to BDC & moves
to upward.
Piston pushes out the burnt gases to the
atmosphere through the exhaust valve.
Hence called exhaust stroke & the
engine is ready to begin the cycle again.

12. BASIC COMPONENTS USED
1. ENGINE BLOCK
2. Crankshaft
3. Cam shaft
4. Cylinder head
5. Piston
6. And many more…
13. DETAILED VIEW OF THE COMPONENTS
1. ENGINE BLOCK
– Cast in one piece. The basis for most of the parts
of the engine.
– ‘V’ Shape
– 2 Sides
• Generator Side
• Free Side
14. 2. CRANKSHAFT
– Singular costliest item in diesel engine.
– Medium of transforming reciprocating motion to
rotary motion.
– Balance weights can be either bolted up or welded.
15. 3. CAM SHAFT
– Performs the vital role of opening & closing inlet &
exhaust valves.
– Allow timely injection of fuel inside the cylinder.
– Usually 3 cams for each cylinder-
2 outer cams for exhaust & inlet valves
1 central cam for fuel injection.
16. 4. CYLINDER HEAD
– CH is held on the cylinder liners by 7 hold down
studs.
– Subjected to high shock stress & combustion
temperature at the lower face.
– Complicated casting where cooling passages are
cored for holding water.
– Space had been provided for passage of inlet air &
exhaust gases.
– Space for fuel injection nozzles, valve guides &
valve seat.
17. 5. PISTON
–Compresses the air to required pressure &
temperature
–Receives the thrust of expanding gases &
transmits the force through connecting rod.
–With the help of piston rings, prevents
leakage of gas from combustion chamber.
18. 6. SOME OTHER PARTS
– PISTON RINGS
• Seal the combustion chamber
• Prevent blow by of air & high
temperature combustion gases.
– CONNECTING ROD
• Connects piston & crank shaft
• Medium of converting reciprocating
motion to rotary motion.
– LINERS
• Forms the wall of the combustion chamber.
• Guides the movement of piston.
19. ADVANTAGES
• More efficient.
• More reliable.
• More durable.
• Release less amount of harmful fumes.
• Easily turbo-charged.
• Produce minimal carbon monoxide.

CAN ACCEPT SYNTHETIC
FUELS
NO HARMFUL EMISSIONS
20. DISADVANTAGES
• More expensive.
• Occasionally servicing can be more costly.
• Parts tend to be more expensive.
• The cost of diesel at the pump is higher.
• Contribute to Greenhouse effect.
• Generally more noisy.
EXPENSIVE
A BIT NOISY
21. • Diesel Engine relies upon compression ignition.
• Compression ratio lies b/w 16:1 and 25:1.
• Temp. increases to 700C to 900C.
• Piston approaches TDC, fuel is injected.
• Ignition instantly occurs, causing a rapid increase in
cylinder temperature & pressure.
• Piston is driven downward with great force, pushing
on the connecting rod & turning the crankshaft.
• Exhaust gases are expelled then.
