What are the two principal classes of heat engines?

What is the main function of the flywheel in an internal combustion engine?

What material is typically used for the cylinder block in heavy-duty engines?

What is the term for the opening in the cylinder head that connects to the inlet valve?

What is the term used for the system of pipes connecting the inlet ports of various cylinders to a common air or air-fuel intake for the engine?

What is the term used for the system of pipes connecting the exhaust ports of various cylinders to a common exhaust pipe?

The piston in an internal combustion engine is typically made of aluminum alloy.

What is the purpose of the connecting rod in an internal combustion engine?

What is the term used for the main body of the engine to which the cylinders are attached, containing the crankshaft and bearings?

What is the main function of the crankshaft in an internal combustion engine?

The ratio of the cylinder volume to the clearance volume is referred to as the compression ratio.

Which type of engine configuration is commonly used in passenger cars?

What type of engine configuration is often used for heavy hauling and vocational work?

Oversquare engines are commonly used in cars with spark ignition (SI) systems.

The inside diameter of the cylinder is called the ...?

What is the term for the distance that the piston travels from its topmost to its bottommost position in the cylinder?

What is the term for the volume swept by the piston as it moves between the top dead center and the bottom dead center?

What is the term for the volume confined in the cylinder above the piston when the piston is at top dead center?

What is the term for the ratio of the cylinder volume to the clearance volume?

Higher compression ratios generally lead to improved engine efficiency and power output.

What happens when the compression ratio is too high?

A short stroke engine is also known as an oversquare engine.

A long stroke engine is also known as an undersquare engine.

What is the most common type of engine configuration used in passenger cars?

Which type of engine configuration is preferred for heavy-duty applications like trucks?

Oversquare engines excel in high-speed operation.

The engine block serves as a foundation for the engine, providing a mounting point for the cylinders and other engine components.

The crankshaft is responsible for converting the rotational motion of the pistons into linear motion for the vehicle's wheels.

The connecting rod connects the piston to the crankshaft, transferring the force of the piston's motion to the crankshaft.

The flywheel serves to store energy during the power stroke and releases it during other strokes, smoothing out the engine's rotation.

Aluminum alloys are commonly used for pistons due to their high strength and light weight, making them suitable for high-performance applications.

Which of the following is NOT a type of engine configuration?

An engine with a longer stroke than its bore is considered an undersquare engine.

An engine with a shorter stroke than its bore is considered an oversquare engine.

The term 'bore' refers to the distance the piston travels within the cylinder.

An engine with a bore and stroke of the same length is referred to as a 'square engine'.
