All heat data are based on standard conditions according to Annex 0.10. Deviations from standard conditions may change the values in the heat balance and must be taken into account in the layout of the cooling circuit/equipment (intercooler, emergency cooling, etc.). In the specifications, in addition to the general tolerance of ±8% on thermal output, an additional reserve of +5% is recommended for determining the cooling requirements.

Technical parameters

All data in the technical specification are based on full engine load (unless stated otherwise) at the specified temperatures and methane number, and are subject to technical development and modification.

All pressure values must be measured and read with gauge pressure gauges (psi.g.).

[1] At nominal speed and standard ICFN conditions according to ISO 3046-1

Efficiency values are based on a new unit (immediately after commissioning). The effects of deterioration during normal operation can be mitigated through regular service and maintenance work. Reference value --> 65% CH4 / 35% CO2

[3] Average value between oil change intervals according to the maintenance schedule, excluding the oil change quantity

[4] At p.f. = 1.0 according to VDE 0530 REM / IEC 34.1 with relative tolerances, all direct-driven pumps included

[7] As an indicative value at p.f. 0.8, valid only for (engine, generator, TCM). Other peripheral equipment is not considered.

* Standard conditions – if the turbocharger design is rated for an intake air temperature > 30°C without derating, the 1st stage intercooler heat must be increased by 2%/°C starting from 25°C. Deviations between 25 and 30°C are covered by the standard tolerance.

* Hot Country application (V1xx) – if the turbocharger design is rated for an intake air temperature > 40°C without derating, the 1st stage intercooler heat must be increased by 2%/°C starting from 35°C. Deviations between 35 and 40°C are covered by the standard tolerance.

The ignition system of the gas engines complies with the radio interference levels of CISPR 12 and EN 55011 class B (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.

Net brake power that the engine manufacturer declares the engine is capable of delivering continuously at the stated speed between the normal maintenance intervals and overhauls required by the manufacturer. Power determined under the operating conditions of the manufacturer's test bench and adjusted to standard reference conditions.

Barometric pressure: 1000 mbar (14.5 psi) or 100 m (328 ft) above sea level. Air temperature: 25°C (77°F) or 298 K
