SV Technocrats India is India's leading engine cut section model manufacturing company from Pune. SV Technocrats India's Cut section model of single cylinder two stroke diesel engine helps learners to understand its integral parts and functionality. A cut section model of a single-cylinder four-stroke diesel engine would reveal the internal components and illustrate how the engine operates. Here's a detailed description of the key parts that would be visible in the cut section model:

Key Components of a Single Cylinder Four-Stroke Diesel Engine Cut Section Model

1. Cylinder:

o Description: The chamber where the combustion process occurs.

o Function: Contains the air-fuel mixture and the combustion process.

2. Piston:

o Description: The moving component within the cylinder.

o Function: Moves up and down to compress the air, and convert combustion energy into mechanical energy.

3. Crankshaft:

o Description: The rotating shaft that converts the piston's reciprocating motion into rotational motion.

o Function: Drives the connected machinery or vehicle.

4. Connecting Rod:

o Description: The rod that connects the piston to the crankshaft.

o Function: Transmits the motion from the piston to the crankshaft.

5. Fuel Injector:

o Description: The device that injects fuel into the combustion chamber.

o Function: Provides the precise amount of fuel needed for combustion.

6. Intake Valve:

o Description: The valve that allows air to enter the cylinder.

o Function: Opens during the intake stroke to let air in and closes during compression and combustion.

7. Exhaust Valve:

o Description: The valve that allows exhaust gases to exit the cylinder.

o Function: Opens during the exhaust stroke to let burnt gases out and closes during intake and compression.

8. Camshaft:

o Description: The rotating shaft that operates the intake and exhaust valves.

o Function: Timed precisely to open and close the valves at the correct intervals.

9. Cylinder Head:

o Description: The top part of the engine that houses the intake and exhaust valves, and the fuel injector.

o Function: Seals the top of the cylinder and contains the combustion chamber.

Working Principle

First Stroke (Intake)

• The intake valve opens, and the piston moves down from top dead center (TDC) to bottom dead center (BDC), drawing air into the cylinder.

Second Stroke (Compression)

• The intake valve closes, and the piston moves up from BDC to TDC, compressing the air in the cylinder.

• Near the end of the compression stroke, fuel is injected into the compressed air, causing it to ignite due to the high temperature and pressure.

Third Stroke (Power)

• The fuel-air mixture combusts, causing an explosion that forces the piston down from TDC to BDC.

• This stroke provides the mechanical energy that powers the engine.

Fourth Stroke (Exhaust)

• The exhaust valve opens, and the piston moves up from BDC to TDC, expelling the burnt gases from the cylinder.

• The cycle then repeats with the next intake stroke.
