« There was a power failure, the generator
was working as normal.
And then, suddenly, the generator broke down
because of contaminated fuel. »
By becoming more frequent, cut-outs in electricity and voltage drops highlighted the importance of having a reliable emergency generator.
How long have we had this need for diesel ?
It is a question that we have heard thousands of times. In the past, you could store diesel for 20 years with no issues. How is it that modern diesel needs to be treated?
To answer this in simple terms, it is because of caring about the environment. Every country is trying to reduce the environmental impact of fossil-fuel combustion. These efforts, on one hand, have given rise to the introduction of biodiesel blends and, on the other hand, to a stricter control on emissions.
From this point forward, the fuel that we buy is a blend of petrochemical diesel and FAME, a biological element which reduces the pollution caused by fuel combustion. Since 2007, diesel has contained 7% FAME, and this proportion will continue to increase.
Biodiesel is a great invention for the environment, but a problem for those who store fuel. It contains production-phase water and is hygroscopic during storage. Water is a real enemy of clean fuel:
- Water is a real contaminant ;
- It favours the growth of microbes, known as « diesel microbes » ;
- It accelerates contamination for solids like rust.
Standards concerning emissions
Europe has been strengthening the control of emissions on diesel engines since the introduction of the Euro 1 standard in 1992. From this point on, new engines are subject to the Euro 6 standard, which authorises a lower quantity of emissions than ever before.
To adhere to these standards, modern engines almost need clean fuel. Dirty fuel clogs up or damages sensitive components such as injectors and pumps. And old fuel – whether petrochemical or biodiesel – contains colloidal carbon as well as other contaminants, likely to smother or damage modern engines.
The Diesel Service fuel-treatment programme eliminates any kind of contamination, thus ensuring your critical equipment works reliably.
