Page 91: Heavy Fuel Oil (Hfo) Specification
To use any fuels, which do not comply with these specifications (e.g. crude oil), consultation with Technical Service of MAN Diesel & Turbo in Augsburg is required. Heavy fuel oils with a maximum density of 1,010 kg/m3 may only be used if up-to- date separators are installed.
Page 92 010.000.023-05 MAN Diesel & Turbo are as follows: abrasive and corrosive effects, unfavourable combustion characteristics, poor compatibility with mineral oils and, last but not least, adverse effects on the environment. The order for the fuel must expressly state what is not permitted as the fuel specifications that generally apply do not include this limitation.

The tank's ventilation system must be designed in such a way that condensate cannot flow back into the tank.
Page 100 However, a more effective solution is a high com- pression ratio and operational adjustment of the injection system to the igni- tion characteristics of the fuel used, as is the case with MAN Diesel & Turbo piston engines.

It is up to the customer to decide whether or not the use of additives is beneficial. The supplier of the additive must guarantee that the engine opera- tion will not be impaired by using the product.
