CVolumetric efficiency
-
DRelative efficiency
Answer
Correct Answer: Volumetric efficiency
Explanation
GivenRatio: (Volume of charge at NTP) / (Swept volume).
ConceptThat ratio quantifies how effectively the cylinder is filled compared to its displacement and is called volumetric efficiency.
Final AnswerVolumetric efficiency.
