Marine engine pretreatment desulfurization control and monitoring system

A pretreatment desulfurization control and monitoring system for a marine engine, the system comprising:

• a pretreatment desulfurization agent tank for storing a liquid-phase pretreatment desulfurization agent;
• a fuel injection amount sensor installed on a fuel supply line between a fuel tank and a marine and configured to detect an injection amount of fuel;
• a pretreatment desulfurization agent injection amount sensor disposed between the pretreatment desulfurization agent tank and a downstream fuel supply line installed downstream of the fuel injection amount sensor;
• and
• a control panel connected to the sensors in a bi-directionally communicable manner and configured to control and monitor the injection amount of the pretreatment desulfurization agent such that the pretreatment desulfurization agent is mixed with the fuel in a predetermined mixing ratio.
