What is the definition of a Piston?

• A cylindrical component that moves up and down inside the engine cylinder.

• A rotating shaft that transmits power to the wheels.

• A device used to cool the engine.

• A part that stores fuel for the engine.

What is the function of a Piston?

• Converts the pressure from combustion into mechanical motion to drive the crankshaft.

• Stores fuel for the engine.

• Controls the flow of coolant in the engine.

• Generates electrical power for the vehicle.

What is the definition of a Fire Ring?

• The topmost piston ring, also called the top compression ring.

• A type of spark plug used in engines.

• A circular gasket used to seal oil pans.

• A ring used to secure the crankshaft in place.

What is the function of a Fire Ring?

• Seals combustion gases within the combustion chamber, preventing them from leaking.

• Cools the engine by circulating coolant.

• Acts as a spark plug to ignite the fuel-air mixture.

• Filters air entering the combustion chamber.

What is the definition of a Compression Ring?

• A ring located below the fire ring.

• A ring used to seal oil in the engine.

• A ring that connects the piston to the crankshaft.

• A ring that controls the flow of coolant.

What is the function of a Compression Ring?

• Maintains compression pressure and prevents gas leakage into the crankcase.

• Regulates the flow of coolant in the engine.

• Acts as a filter for engine oil.

• Controls the timing of the spark plug.

What is the definition of an Oil Ring?

• A ring with slots/grooves located below the compression rings.

• A ring used to seal the cylinder head to the engine block.

• A ring that connects the piston to the crankshaft.

• A ring that controls the flow of fuel into the combustion chamber.

What is the function of an Oil Ring?

• Scrapes excess oil from the cylinder walls and returns it to the oil pan.

• Provides cooling to the piston by circulating coolant.

• Seals the combustion chamber to prevent gas leakage.

• Controls the movement of the crankshaft.

What is the definition of a Piston Pin (Gudgeon Pin)?

• A hollow shaft that connects the piston to the connecting rod.

• A device used to measure engine temperature.

• A part that controls the fuel injection timing.

• A valve that regulates air intake.

What is the function of a Piston Pin (Gudgeon Pin)?

• Transfers motion and force from the piston to the connecting rod.

• Regulates the flow of fuel into the combustion chamber.

• Controls the opening and closing of engine valves.

• Acts as a seal to prevent oil leakage from the cylinder.
