Question 1: Connecting Rod

Answer:

a mechanical component that connects the piston to the crankshaft.

Question 2: multi-valve cylinder head

Answer:

is a type of cylinder head that has more than two valves per cylinder. Multi-valve cylinder heads can have three, four, or more valves per cylinder, depending on the engine's design.

Question 3: Wrist pins are responsible for ___

Answer:

transmitting the reciprocating motion of the piston to the connecting rod, which in turn rotates the crankshaft to generate mechanical energy.Question 4: Engines can have multiple cylinders, and the number and arrangement of cylinders impact ___

Answer:

the engine's performance and characteristics.

Question 5: The connecting rod is an important component of ___

Answer:

the engine's bottom end and is subjected to significant stresses and forces during operation.Question 6: Camshaft: overhead valve (OHV)

Answer:

In an OHV engine, the camshaft is located in the engine block, and pushrods are used to actuate the valves in the cylinder head

Question 7: single overhead cam (SOHC) engine

Answer:

has one camshaft that operates all the valves

Question 8: What are the two types of strokes?

Answer:

upward (also called compression stroke) and downward (expansion or power stroke)

Question 9: How does a connecting rod work? (regarding motion)

Answer:

converts the reciprocating motion of the piston into rotary motion of the crankshaft, which is used to drive the vehicle's wheels.

Question 10: An internal combustion engine works by ___

Answer:

burning fuel inside the engine to produce heat, which is then converted into mechanical energy

Question 11: The cylinder head plays a critical role in ___

Answer:

controlling the flow of air and fuel into the engine and exhaust gases out of the engine.

Question 12: Intake Valve

Answer:

a mechanical component that allows the air-fuel mixture to enter the engine's combustion chamber.

Question 13: Camshaft: timing belt/chain

Answer:

a component that connects the camshaft to the crankshaft and ensures that the valves open and close at the correct time.

Question 14: Cylinder

Answer:

The cylindrical chamber is where the air-fuel mixture is compressed and burned to produce heat energy, which is then converted into mechanical energy.

Question 15: The engine block contains passages for

Answer:

coolant, oil, and other fluids and is designed to withstand the high pressures and temperatures of the combustion process.

Question 16: Where is the crankshaft located?

Answer:

in the engine block and is connected to the pistons via the connecting rods.

Question 17: cylinder head

Answer:

is a component that sits on top of the cylinder and seals the combustion chamber.

Question 18: Piston rings are ___

Answer:

small metal rings that fit into grooves on the piston's outer surface. They provide a seal between the piston and the cylinder wall, which prevents the air-fuel mixture and combustion gases from leaking past the piston

Question 19: Cylinder heads typically contain ___

Answer:

intake and exhaust valves, which are operated by the camshaft, and other components, such as the spark plug and fuel injector.

Question 20: Wrist pins

Answer:

are small, cylindrical components that connect the piston to the connecting rod.

Question 21: What is an engine block typically made of?

Answer:

typically made of cast iron or aluminum and is responsible for supporting the engine's weight and providing a rigid mounting point for the various engine components

Question 22: Wrist pins are typically made of

Answer:

of steel or other high-strength materials

Question 23: This refers to the number of camshafts in an engine.

Answer:

single and double arrangements

Question 24: A "stroke" refers to

Answer:

the movement of the engine's piston inside the cylinder during each phase of the cycle.

Question 25: In a car, the engine is typically ___

Answer:

an internal combustion engine

Question 26: engine block

Answer:

is the main structural component that houses the cylinders, pistons, and other components.

Question 27: Piston rings help regulate ___

Answer:

the amount of oil that enters the combustion chamber to lubricate the cylinder walls, ensuring smooth operation and minimizing wear and tear.
