22. You are onboard a vessel with a slow-speed crosshead type engine. The fuel just received has a significantly lower sulfur content than the previous bunkers. Which of the following would be a concern due to the reduced sulfur content?

Reduced sulfur content in fuel necessitates a reevaluation of cylinder oil base number to prevent detrimental deposits and wear, as the alkalinity required to neutralize acids formed during combustion decreases with lower sulfur levels; fuel supply system pressure, purifier gravity disk size, and fuel injection temperature are not directly affected by sulfur content.
