Question 51Motor Plants - QMED
70% to passIn a naturally aspirated diesel engine, the volume of air intake is directly associated with engine _______________.
Acompression ratio
Bdisplacement
Cfuel pressure
Dcylinder clearance volume
AI Explanation
You are correct, the answer is B) displacement. In a naturally aspirated diesel engine, the volume of air intake is directly associated with the engine displacement. The displacement refers to the total volume swept by the pistons as they move from top dead center to bottom dead center. This directly determines the amount of air that can be drawn into the engine, as the pistons create a vacuum that pulls air into the cylinders. The other answer choices are incorrect because they are not directly related to the volume of air intake. The compression ratio, fuel pressure, and cylinder clearance volume do not determine the amount of air drawn into the engine in a naturally aspirated system.
