Rated / maximal power
All given information applies to the engine at 0m sea level and a surrounding temperature of +20c°. The total capacity of the device must be reduced because of cooling issues when using the device
in higher temperatures or in greater heights (see 3.2. Derating chart).
2)
Fuel
You cannot use fuels other than regular diesel such as biodiesel, plant oil or heating oil without changing the engine! Never use fuels other than standard diesel without clearing with ROTEK
first. Your engine could be damaged! We would like to point out that in Western Europe it is mandatory to mix biodiesel into available diesel fuels. Because of this mix, the “normal” diesel
only keeps about 6 months in storage! After about 6 months microbial growth increases considerably in the diesel. These organisms further on corrosion in tank and motor, and they produce
biomass which clogs the injection nozzle, the injection pump and damages the motor over time. This is a particular problem if the engine is only used rarely. Pay attention to the date you last
refuelled and drain the tank in appropriate time intervals. Also available are types of so called "premium diesel" (SHELL© V-Power, ARAL© Ultimate, OMV© MaxxMotion, ...) which either
do not contain biodiesel at all (ex. BP© Ultimate) or contain special biodiesel made from hydrated plant oils (ex. OMV© Maxxmotion) and can therefor be stored for 2 years without worries.
