OVERVIEWThe G Build engine is specifically designed as a Power generating engine suitable for use in unregulated emissions territories. It is durable, reliable and easy to maintain with oil and filter changes up to 250 hours, dependant on operational conditions. It is designed for continuous operation in ambient temperatures up to 45°C (113°F) and a cold start capability down to -25°C (-13°F).

Note:This engine does not comply with Harmonised International Regulated Emissions Limits.

* Optional items standard on most builds.

RATING DEFINITIONSTO ISO 3046ISO Standard ConditionsBarometric pressure 100 kPaRelative humidity 30%Ambient air temperature at the inlet manifold 25°C

Fixed Speed: Continuous Power (ICN)The power in kW which the engine is capable of delivering continuously at the stated crankshaft speed, under ISO 3046 standard conditions, measured at the flywheel without powerabsorbing accessories, provided that the engine is overhauled and maintained in good operating condition and that fuel to BS EN 590 Class A1 or A2, and lubricating oils to the correct performance specification and viscosity classification as recommended by Lister Petter Power Systems Limited are used.

Fixed Speed (Fuel Stop):Overload Power (ICXN)The maximum power in kW which the engine is capable of delivering intermittently at the stated crankshaft speed for a period not exceeding one hour in any period of twelve hours of continuous running, immediately after working at the continuous power, under ISO 3046 standard conditions and with the provisions specified for continuous power in item (1) above, but with the fuel limited so that the fuel stop power cannot be exceeded.

DeratingFor non-standard site conditions, reference should be made to relevant BS, ISO & DIN standards.

Notes: 1. Power ratings are measured at the flywheel end.2. Power ratings and fuel consumption figures apply to a fully run-in, non-derated engine without a radiator and fan fitted, and without power-absorbing accessories or transmission equipment.
