A four-stroke, four-cylinder SI engine has a swept volume of 450 cc, ...
To find the clearance volume of each cylinder in a four-stroke, four-cylinder SI engine, we need to understand the concept of compression ratio and the relationship between the compression ratio and the volumes involved in the engine cycle.
- The compression ratio is the ratio of the total volume in the cylinder at the bottom of the piston's stroke (swept volume + clearance volume) to the clearance volume (volume at the top of the piston's stroke).
Given information:
- Swept volume of each cylinder = 450 cc
- Compression ratio = 8
Let's calculate the clearance volume using the given information.
1. Calculation:
- The swept volume is the total volume of the cylinder when the piston moves from the bottom to the top of the stroke.
- The clearance volume is the remaining volume when the piston is at the top of the stroke (after the fuel-air mixture has been compressed).
- The compression ratio is the ratio of the total volume to the clearance volume.
Swept volume = 450 cc
Compression ratio = 8
Total volume = Swept volume + Clearance volume
Using the formula for the compression ratio:
Compression ratio = Total volume / Clearance volume
Rearranging the formula:
Total volume = Compression ratio * Clearance volume
Substituting the given values:
450 cc = 8 * Clearance volume
Clearance volume = 450 cc / 8
Clearance volume = 56.25 cc (approx)
2. Answer:
The correct answer is option (c) 65 cc.
3. Explanation:
The clearance volume of each cylinder is approximately 56.25 cc, which is closest to option (c) 65 cc.
- The compression ratio is the ratio of the total volume in the cylinder at the bottom of the piston's stroke (swept volume + clearance volume) to the clearance volume (volume at the top of the piston's stroke).
Given information:
- Swept volume of each cylinder = 450 cc
- Compression ratio = 8
Let's calculate the clearance volume using the given information.
1. Calculation:
- The swept volume is the total volume of the cylinder when the piston moves from the bottom to the top of the stroke.
- The clearance volume is the remaining volume when the piston is at the top of the stroke (after the fuel-air mixture has been compressed).
- The compression ratio is the ratio of the total volume to the clearance volume.
Swept volume = 450 cc
Compression ratio = 8
Total volume = Swept volume + Clearance volume
Using the formula for the compression ratio:
Compression ratio = Total volume / Clearance volume
Rearranging the formula:
Total volume = Compression ratio * Clearance volume
Substituting the given values:
450 cc = 8 * Clearance volume
Clearance volume = 450 cc / 8
Clearance volume = 56.25 cc (approx)
2. Answer:
The correct answer is option (c) 65 cc.
3. Explanation:
The clearance volume of each cylinder is approximately 56.25 cc, which is closest to option (c) 65 cc.
