John Deere Offers New Engine Ratings
John Deere Power Systems has announced new ratings for several of its marine engines.
“As the marine market evolves, so do our customers’ needs,” said Heather Balk, marine market planner at John Deere Power Systems. “Keeping that in mind, we are committed to providing the marine engines and power ratings they need to be successful. John Deere continues to expand our portfolio for specific markets and offer additional ratings to comply with a wide array of emissions regulations.”
As many customers are beginning to introduce hybrid power in their vessels, Deere has announced the upcoming release of a PowerTech 6090SFM85 rating for hybrid vessels with diesel power.
The variable speed rating will be 242 kw. (325 hp.) at 2,000 rpm., 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. This rating is ideal 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.
To address the market-specific needs of inland waterway applications, John Deere will offer two marine generator drive ratings that are EU Stage V compliant on the PowerTech 4045TFM85 and 6068AFM85 models. The 4.5-liter rating will be 61 kwm. prime at 1,500 rpm., and the 6.8-liter rating will be 117 kwm. prime at 1,500 rpm. Both prime ratings include a 10 percent overload capability and conform to ISO 8528 prime power.
The 4.5- and 6.8-liter engines feature a water-cooled exhaust manifold and turbocharger, both of which create a cool and quiet environment for passengers and crew. Both engines are type approved by the following marine classification societies: ABS, BV, CCS, DNV-GL and LR.
The EU Stage V 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 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.
All John Deere marine power solutions are available through authorized John Deere marine engine distributors and marine dealers.
