BB00.40-P-0141-00A Diesel Fuel For Industrial Engines

Diesel fuels should be used for industrial engines that comply with the quality requirements as under Sheets 131.0, 132.1 and 132.3.

In special instances direct-injection engines may be permitted to use diesel fuel with a different grade, if such a fuel fulfills the following minimum requirements:







The increase in sulfur content which these grades normally exhibit, requires shorter oil change intervals.

Particularly where diesel fuel with a high sulfur content is used it is very important to ensure that only tested and approved engine oils as under sheets 228.0/.1/.2/.3 /.5 are used. The higher the grade of oil the easier it is to compensate for the negative effect exhibited because of the sulfur content.

If the fuel has a high viscosity it may be necessary to conduct a fuel preheating operation.

If the density of the diesel fuel is greater than 0.86 g/ml at 15 °C, the injection quantity is to be reduced as follows:







To this end the injection pump should be removed and readjusted on the injection-pump test bench taking the fuel-quantity reduction into account. This work must be conducted by skilled personnel only.

The fuel precleaner and fuel filter should be checked and cleaned on a more regular basis. In some cases it may be necessary for such diesel-fuel grades to undergo a centrifuging operation beforehand.

It should be pointed out that the use of unfavorable diesel fuel grades will exert a considerable influence on the engine output as well as its service life. If such unfavorable diesel-fuel grades are used it is impossible to achieve the same results as when using excellent diesel-fuel grades. These special cases, i.e. the use of the above fuel grades, must be previously clarified with the Abteilung Betriebsstoffe EP/MOR (EP/MOR Operating Fluids department).
