Question 129Motor Plants - Assistant Engineer

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.
