Calculate The Total Engine Capacity In Liters Of A Four-cylinder Engine If The Clearance Volume Is $30 \, \text{mL}$ And The Swept Volume Is $230 \, \text{cm}^3$.
Introduction
In the world of engineering, understanding the intricacies of engine capacity is crucial for designing and optimizing internal combustion engines. Engine capacity, also known as engine displacement, refers to the total volume of air and fuel that an engine can draw in and process in a single cycle. In this article, we will delve into the calculation of engine capacity, specifically for a four-cylinder engine, and explore the factors that influence this critical parameter.
Understanding Engine Capacity
Engine capacity is typically measured in liters (L) or cubic centimeters (cm³). It is calculated by multiplying the swept volume of the engine by the number of cylinders. The swept volume, also known as the displacement volume, is the volume of the space inside the engine's cylinders that is swept by the pistons as they move up and down. The clearance volume, on the other hand, is the volume of the space inside the cylinders that is not swept by the pistons.
Calculating Swept Volume
To calculate the swept volume of the engine, we need to convert the given volume from cubic centimeters (cm³) to milliliters (mL). Since 1 cm³ is equal to 1 mL, the swept volume of 230 cm³ is equivalent to 230 mL.
Calculating Engine Capacity
Now that we have the swept volume, we can calculate the engine capacity by multiplying it by the number of cylinders. In this case, we have a four-cylinder engine, so we will multiply the swept volume by 4.
Formula: Engine Capacity = Swept Volume x Number of Cylinders
Engine Capacity = 230 mL x 4 Engine Capacity = 920 mL
Converting to Liters
To express the engine capacity in liters, we need to convert the volume from milliliters (mL) to liters (L). Since 1 L is equal to 1000 mL, we can divide the engine capacity by 1000 to get the volume in liters.
Formula: Engine Capacity (L) = Engine Capacity (mL) / 1000
Engine Capacity (L) = 920 mL / 1000 Engine Capacity (L) = 0.92 L
Clearance Volume
The clearance volume is given as 30 mL. To calculate the total engine capacity, we need to subtract the clearance volume from the swept volume.
Formula: Total Engine Capacity = Swept Volume - Clearance Volume
Total Engine Capacity = 230 mL - 30 mL Total Engine Capacity = 200 mL
Converting to Liters
To express the total engine capacity in liters, we need to convert the volume from milliliters (mL) to liters (L). Since 1 L is equal to 1000 mL, we can divide the total engine capacity by 1000 to get the volume in liters.
Formula: Total Engine Capacity (L) = Total Engine Capacity (mL) / 1000
Total Engine Capacity (L) = 200 mL / 1000 Total Engine Capacity (L) = 0.2 L
Conclusion
In conclusion, the total engine capacity of a four-cylinder engine with a swept volume of 230 cm³ and a clearance volume of 30 mL is 0.92 L. This calculation is essential for designing and optimizing internal combustion engines, and it highlights the importance of understanding the intricacies of engine capacity.
