41. The fishing industry factory ship to which you are assigned has a main propulsion engine of the type shown in the illustration. In terms of piston action, operating cycle, and piston type, what statement is true concerning this engine type

The engine features two pistons within a single cylinder, combustion occurring between their crowns, and utilizes ports for intake and exhaust, indicating a single-acting, two-stroke cycle, opposed-piston design. This configuration distinguishes it from engines with cylinder heads, crosshead pistons, or double-acting mechanisms, and the presence of ports and a blower confirms the two-stroke cycle.
