70% to passWhich of the listed design features is most common with a two-stroke cycle, low- speed main propulsion diesel engine?
APiston rod and crosshead construction
B90 degree 'V' configuration
CDouble acting trunk type pistons
DSingle reduction gearing
AI Explanation
The correct answer is A) Piston rod and crosshead construction. The piston rod and crosshead construction is the most common design feature for a two-stroke cycle, low-speed main propulsion diesel engine. This design allows for the transfer of power from the piston to the crankshaft while managing the high pressures and loads associated with two-stroke, low-speed diesel engines. The other options are not as commonly associated with this type of engine. The 90-degree 'V' configuration (B) is more typical of high-speed diesel engines, double-acting trunk type pistons (C) are less common, and single reduction gearing (D) is not a unique design feature of two-stroke, low-speed diesel engines.
