All units are in g/hp-hr and are EPA D2 cycle values.
Emission levels of the engine may vary as a function of ambient temperature, barometric pressure, humidity, fuel type and
quality, installation parameters, measuring instrumentation,
etc. The data provided are laboratory results from one engine
representing this rating. The data was obtained under controlled environmental conditions with calibrated instrumentation
traceable to the United States National Bureau of Standards
and in compliance with US EPA regulations found within 40 CFR
Part 89. The weighted cycle value from each engine is guaranteed to be below the US EPA Standards at the US EPA defined
conditions.
// // // // Materials and specifications subject to change without notice.
Ambient capability factor at 984 ft (300 m). Consult your
local MTU Onsite Energy Power Generation Distributor for
other altitudes.
Standby ratings apply to installations served by a reliable
utility source. The standby rating is applicable to varying
loads for the duration of a power outage. No overload capability for this rating. Ratings are in accordance with
ISO-3046/1, BS 5514, AS 2789, and DIN 6271.
Prime power ratings apply to installations where utility power
is unavailable or unreliable. At varying load, the number of
generator set operating hours is unlimited. A 10% overload
capacity is available for one hour in twelve. Ratings are in
accordance with ISO-8528/1, overload power in accordance
with ISO-3046/1, BS 5514, AS 2789, and DIN 6271. For
limited running time and base load ratings, consult the
factory.
Deration Factor:
Altitude: 2% per 1,640 ft (500 m) above 3,281 ft
(1,000 m)* at 77°F (25°C).
Temperature: 1% per 9°F (5°C) over 113°F (45°C) at
328 ft (100 m).
*Contact factory for deration above 6,562 ft (2,000 m).
