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

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

1. Cylinder Block

oDescription: The main structure containing four cylinders where the pistons move.

oFunction: Houses the cylinders and provides structural support.

2. Cylinders

oDescription: The chambers where the combustion process occurs.

oFunction: Contain the fuel-air mixture and the combustion process.

3. Pistons

o Description: Moving components within each cylinder.

o Function: Move up and down to compress the fuel-air mixture and convert combustion energy into mechanical energy.

4. Crankshaft

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

o Function: Drives the connected machinery or vehicle.

5. Connecting Rods

o Description: The rods that connect each piston to the crankshaft.

o Function: Transmit the motion from the pistons to the crankshaft.

6. Spark Plugs

o Description: Devices that ignite the fuel-air mixture in each cylinder.

o Function: Provide the spark necessary for combustion.

7. Intake Valves

o Description: Valves that allow the fuel-air mixture to enter each cylinder.

o Function: Open during the intake stroke to let the mixture in and close during compression and combustion.

8. Exhaust Valves

oDescription: Valves that allow exhaust gases to exit each cylinder.

oFunction: Open during the exhaust stroke to let burnt gases out and close during intake and compression.

Working Principle

First Stroke (Intake)

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

Second Stroke (Compression)

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

Third Stroke (Power)

• Process: The spark plug ignites the compressed air-fuel mixture, causing an explosion that pushes the piston down from TDC to BDC, providing the power to the crankshaft.

Fourth Stroke (Exhaust)

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

SV Technocrats India supplies these equipment for CSR activities of corporates.
