A big number of on-site power generator systems are connected with diesel-fueled engines. Generally, the diesel fuel is stored inside generator tanks that are either above the ground or under the ground. Due to restrictions on the engine’s fuel capacity, normally a “day tank” is needed to use as an immediate substitute for fuel supply. The day tank’s short distance to the engine allows the fuel pump to draw fuel smoothly.

A day tank can be stand-alone or a sub-base type design installed on the base of the generator, just underneath the engine. In either case, fuel supply to the engine is conjoined with the day tank and other piping networks.

What are the common problems?

One of the most common circulation issues in diesel engines is their nature of burning more fuel than needed for the combustion process. However, the extra fuel consumed is not wasted as it helps the engine remain cool and lubricated. The notable thing here is that the excess fuel is automatically returned to the generator tanks after a certain cycle.

Nowadays, engine ...
... manufacturers label their products specifying the maximum temperature needed to achieve maximum output. For example, some engines may decrease fuel density and lubricity in the engine by 1% for every 10 Fahrenheit increase in temperature. At a certain exceeding temperature, some engines may automatically turn off by their protection features.

What are the solutions?

Generators are well-defined as emergency power backup systems for residential, commercial, and industrial needs. They are widely used for commercial purposes such as in malls, hospitals, and manufacturing plants where consistent power supply is necessary. Whether we talk about boat gas tanks or for car fuel systems, they can only run the respective application for a certain amount of time. An efficient fuel supply unit should ensure that the engine will be able to operate for this maximum timeframe.

Solution 1

One of the perfect solutions for preventing fuel temperature from increasing is using a radiator-mounted fuel cooler. The cooler will work effectively in reducing the excess heat from the fuel and will prevent it from reaching a hazardous level. Some EPSS installation may come with specifications elaborating how the returning fuel to the engine should be treated.

Solution 2

The other solution is to design a fuel circulation system in a way that the engine’s return fuel pours off back to the primary storage boat gas tanks. Return generator tanks are designed to get return fuel from the motor and when connected with a pump, it can lead the hot fuel to the bulk storage system, where it can dissolve with the larger volume of fuel.
