Deere diesel engines' efficiency to improve

Deere has manufactured a new diesel engine that is more efficient and complies with Tier 4 standards.

An efficiency enhancer has been developed for diesel engines, John Deere Power Systems announced.

A fan drive that operates at variable speeds and was installed in the factory soon will be available for the complete lineup of Interim Tier 4/Stage III B off-highway and gen-set diesel engines.

"This component further enhances the line of simple, fuel-efficient and field-proven technologies we're using to meet the more stringent Interim Tier 4/Stage III B emissions requirements," according to Doug Laudick, manager of product planning at John Deere Power Systems. "The variable-speed fan optimizes performance and minimizes operating costs, making it valuable for most mobile and stationary applications."

Owners of John Deere farm equipment will capitalize on being able to save money with the upgrade.

"In fact, our research shows that the payback period for variable-speed fan technology is short," Laudick said. "Based on a fuel cost of $3 per gallon, the payback period is approximately 400 hours on a 9.0L engine operating at a 60 percent load factor in OEM applications. That is a significant return on an investment that already benefits emissions, performance and durability."
