Disclosed herein are a fuel supply system for ships and a fuel supply method using the same. The fuel supply method includes: 1) supplying an excess amount of liquefied gas as fuel to an incompressible fluid-fueled engine (E); 2) cooling unconsumed fuel discharged from the engine (E) through heat exchange with liquefied gas discharged from a storage tank (T); 3) returning the unconsumed fuel discharged from the engine (E) and having been cooled through heat exchange in step 2) to the storage tank (T); and 4) supplying the liquefied gas discharged from the storage tank (T) and having been used as refrigerant for heat exchange in step 2) to the engine (E). The fuel supply method can prevent cavitation in the engine (E) by supplying the excess amount of liquefied gas sufficient to accommodate variation in load of the engine (E) as fuel to the engine (E).

A method for controlling an internal combustion engine cooling system includes pumping coolant in an engine cooling loop with a coolant pump, pumping the coolant in an air cooler loop that includes a liquid-to-liquid heat exchanger with the coolant pump, and receiving a condition signal indicative of at least one condition associated with the internal combustion engine. The method also includes, based on the condition signal, adjusting a position of a flow control valve to modify a flow of coolant to the liquid-to-liquid heat exchanger.

Methods and systems are provided for reducing ice formation in a charge air cooler. In one example, a method includes, operating a radiator fan of a vehicle in a first direction to cool an engine of the vehicle, and reversing a direction of rotation of the radiator fan to blow heated air towards a charge air cooler, the charge air cooler arranged proximate a radiator of the vehicle. Operating the radiator fan in a first direction may be based on the engagement of one or more gears of a transmission of the vehicle while operating the radiator fan in the reverse direction may be based on an engine temperature condition, one or more ambient weather conditions, and an engine idle condition.
