Give a flow chart of how the inlet and exhaust valve operate in the internal combustion engine of a tractor.
abruzzese [7]

Flow chart of a system is a diagrammatic representation of how that system performs it's functions.

<h3>The flow chart of internal combustion engine</h3>

The flow chart of internal combustion engine is the diagrammatic representation of how the engine works.

The inlet valve of the engine is the valve that allows for the entry of fuel-air mixture into the engine.

The exhaust valve of the engine is the allows for the outflow of used gases from the engine.

From the attached flow chart, Intake valves are opened to allow the flow of an air/fuel mixture into the engine's cylinders prior to compression and ignition, while exhaust valves open to permit the expulsion of exhaust gases from the combustion process after ignition has occurred.
