In a cylinder leakage test, what does a higher percentage indicate?

• A. Better engine performance
• B. Worse sealing of the cylinder
• C. Improved fuel efficiency
• D. Increased power output

Answer: (B)

In a cylinder leakage test, a higher percentage indicates worse sealing of the cylinder. This test measures the amount of air that escapes from the cylinder when it is pressurized. If the percentage of leakage is high, it means that there are significant leaks present within the cylinder. When the cylinder seals are compromised, this can lead to a loss of compression, affecting the engine's overall performance. Poor sealing can arise from worn piston rings, damaged cylinder walls, or faulty valve seats. As a result, the engine will likely experience a decrease in power, efficiency, and overall functionality. In contrast, a lower leakage percentage signifies better sealing, allowing for more efficient compression and improved engine performance. Therefore, it is critical to interpret the results of a cylinder leakage test accurately: a higher leakage percentage is detrimental, indicating that the engine may require repairs to restore its function.
