Deere’s New Global Marine Engine Ratings
By Mike Osenga30 October 2019
John Deere Power Systems (JDPS) has announced new global marine diesel ratings, including ratings for China, as well as a brand-new hybrid rating.
With many in the marine markets considering a hybrid power solution, John Deere is announced the upcoming release of a PowerTech 6090SFM85 rating for hybrid vessels with diesel power (pictued here). The variable speed rating will be 325 hp (242 kW) at 2000 rpm and will meet U.S. Environmental Protection Agency Marine Tier 3 and International Maritime Organization Tier 2 emissions standards and will be certified to E3 propulsion test cycle for commercial applications used with variable pitch or electronically coupled propellers.
JDPS said this rating is applicable for hybrid vessels that require a variable-speed generator drive engine to develop electrical power for any combination of electric propulsion, energy storage, hotel load and auxiliary electric loads.
For inland waterway applications, John Deere will offer two marine generator drive ratings that are EU Stage 5 compliant on the PowerTech 4045TFM85 and 6068AFM85 models. The 4.5L rating will be 61 kWm prime at 1500 rpm and the 6.8L rating will be 117 kWm prime at 1500 rpm. Both prime ratings include a 10% overload capability and conform to ISO 8528 prime power.
The 4.5L and 6.8L engines feature a water-cooled exhaust manifold and turbocharger. Both engines are type approved by the following Marine Classification Societies: ABS, BV, CCS, DNV-GL, and LR.
The EU Stage 5 generator drive ratings below 130 kW are anticipated to be available to order later this year, with production set to begin in early 2020.
Keeping its global customers in mind, John Deere said it is prepared to meet China Stage I marine emissions standards. These standards apply to new marine engines at or above 37 kW that are registered in China for operation in Chinese territorial waters.
John Deere will release new emission label options for 50 Hz generator drive ratings for the PowerTech 4045TFM85, 4045AFM85 and 6068AFM85 engines, which will comply with China Stage I marine emissions standards. The new emission label options are expected to be available in early 2020.
“As the marine market evolves, so do our customers’ needs. Keeping that in mind, we are committed to providing the marine engines and power ratings they need to be successful,” said Heather Balk, marine market planner at John Deere Power Systems. “John Deere continues to expand our portfolio for specific markets and offer additional ratings to comply with a wide array of emissions regulations.”
