Question 34Motor Plants - Assistant Engineer
70% to passThe bore of a diesel engine cylinder describes the _______________.
Aswept volume of the cylinder
Binside diameter of the cylinder
Cpiston displacement in the cylinder
Dlength of the piston stroke
AI Explanation
The correct answer is B) the inside diameter of the cylinder. The bore of a diesel engine cylinder refers to the inside diameter of the cylinder, which is a key specification that determines the engine's displacement and power output. The bore, along with the piston stroke length, defines the volume of the cylinder and the amount of air/fuel mixture that can be combusted during each engine cycle. The other options are incorrect because they do not directly describe the bore. Option A refers to the swept volume, option C describes the piston displacement, and option D is the length of the piston stroke - none of which are the same as the cylinder bore.
