Obviously today diesel is a much cleaner fuel than before, but still maintains high concentrations of impurities. Gas oil is basically born as a resultant fuel during oil refining, so we can say that diesel is a refining by-product. It is advisable to make a brief reference to the type of fuel that we take into consideration in this article: Diesel fuel for motor vehicles. All this has a price from a technical point of view, that is the need to replace the lubricant regularly so that it does not lose its lubricating properties. The result is a continuous, albeit slight, thermal excursion of the oil which, being preheated, manages to maintain the optimum viscosity in the event of start-up. Pre-heating operation is regulated by a thermostat that activates and deactivates the system based on the temperature reached. In both cases the preheating systems keep the engine warm and ready to start in any season. Preheater is installed on the coolant circuit or under the oil sump. The emergency generators are (depending on the application) equipped with an engine preheater.

Paradoxically, a generator in an emergency network service may need to replace the engine oil in an equal way or even greater than that of a generator set in "prime" operation, that is, it works continuously. The functioning of the oil depends on its chemical properties, therefore an oil of a proven quality, which respects the specifications of the engine, can withstand maintenance intervals higher than a lower quality lubricant, but this does not drastically limit the need to replace it. The engine lubricant does its job of adjusting the friction between the moving parts of the engine and preventing overheating of one or more parts. Is there any reason why we can voluntarily afford the luxury of "deactivating" our kidneys? Not even for a dream, we know that it would lead to death in a short time.Įven the engine, whether it is diesel, petrol or gas, cannot work or simply be ready to run without a proper maintenance, even when it is "sleeping", that’s to say when it is off!Įven the best synthetic oil must be replaced. When in carrying out its work, the Blood needs to be filtered, which is regularly done by the "Kidneys".ĭo the kidneys stop working when we sleep? No. To answer this question, let us take as an example the Human Body, an extraordinary machine that uses a very complex system of transporting oxygen and other vital elements to operate, such as "the blood". Why should the engine of a switched-off generator need to have filters and lubricating oil replaced? Maintenance is to be carried out following the instructions of the manufacturer who usually prescribes the same at "n" hours of operation or every year, whichever comes first. The generators in emergency service based on the hours totalled would not reach maintenance time even after 5 years, in fact it is rare to find an emergency generator that has worked for hundreds of hours! The common place is to check the number of total hours of operation and to assess based on whether the time has come to do maintenance. The commonplace is to check the number of total hours of operation and to assess based on whether the time has come to do maintenance.
What some users, and also some technicians, still fail to accept, is the need to perform maintenance of the generator installed for emergency service which is also called "stand-by": that type of generator that starts only in case of mains failure. This question has an intuitive answer, in fact it is known that in general maintaining something preserves its functionality, therefore the maintenance of an engine, including the replacement of all filtering elements, serves to keep the engine running and therefore the whole machine. Why is it so important to replace engine filters? To these you can also add pre-filters that are installed depending on the case and the different applications. Water filter, also called separator filter When we mention the filters, we usually refer to the most common ones, in fact the generator’s engine, usually has four types of filters:Ĥ.
