MAT 101 DrG flashcard 9. Engine displacement and Compression ratio

Front

What is the formula for calculating the volume of a cylinder?

Back

Volume = π × r² × h, where r is the radius and h is the height.

Front

How do you convert diameter to radius?

Back

Radius = Diameter / 2.

Front

What is engine displacement?

Back

Engine displacement is the total volume of all the cylinders in an engine, typically measured in liters or cubic centimeters.

Front

How do you calculate engine displacement using the formula?

Back

Engine Displacement = π × r² × h, where r is the radius of the cylinder and h is the height (or stroke) of the cylinder.

Front

What is the significance of engine displacement in automotive engineering?

Back

Engine displacement affects the power output and efficiency of an engine; larger displacement generally means more power.

Front

What is the relationship between stroke and bore in an engine?

Back

Stroke is the distance the piston travels within the cylinder, while bore is the diameter of the cylinder.

Front

If the stroke is 3.75 inches and the bore is 4.25 inches, how do you find the engine displacement for 8 cylinders?

Back

Use the formula: Engine Displacement = (π × (bore/2)² × stroke) × number of cylinders.

Front

What is the volume of a cylinder with a height of 10 cm and a diameter of 5 cm?

Back

The volume is 196.35 cm³.

Front

What is the volume of a cylinder with a height of 10 cm and a radius of 5 cm?

Back

The volume is 785.40 cm³.

Front

How do you calculate the volume of a cylinder with a given height and radius?

Back

Use the formula: Volume = π × r² × h.
