Question

Quizplus · Accepted Answer

Technician A is incorrect because a "slipper" skirt piston is actually a type of piston with sides cut away to reduce weight, not a full skirt piston used on long stroke engines. Technician B is also incorrect because a piston skirt cut away on its sides to clear the crankshaft counterweights is known as a "slipper" skirt, not a "trunk" skirt.
