About this file
This document is an Engine Performance Curve specification sheet for a 9.0L Marine Generator Engine Model by John Deere. The engine is rated at 60 Hz and delivers 298hp (222kW) at 1800 RPM, designed for marine applications with EPA Marine Tier 3 and IMO Tier II compliance. The performance data includes prime power of 244-255 kVA with a 10% overload capability, and the engine is specifically intended for constant speed operation in power generation or auxiliary applications such as generators and hydraulic pumps.
The technical specifications detail reference conditions including air intake restrictions, exhaust back pressure, and precise operating parameters at 77°F air inlet temperature and 104°F fuel inlet temperature. The performance data table provides a comprehensive breakdown of engine performance across different load percentages (25% to 110%), showing power output, crank torque, fuel consumption, and brake-specific fuel consumption (BSFC). Key notes emphasize that the marine generator rating allows for an unlimited number of hours per year in commercial applications, with an average 24-hour load not exceeding 67% of the prime rating.

Notes:
Marine Generator: The Marine generator engine rating is the power available under normal varying electrical load factors for an unlimited number of hours per year in commercial applications.
This rating incorporates a 10% overload capability, and conforms to ISO 8528 prime power. Average load over a 24-hour period shall not exceed 67% of the prime rating, of which no more than 2 hours are between 100% and 110% of the prime rating.
Constant speed engines are not certified for constant speed propulsion applications (i.e. variable pitch proppeller, hybrid porpulsion system).
Possible applications: This rating is used for applications that require constant speed operation in power generation or auxiliary applications such as generators and hydraulic pumps.
