Yanmar America Corp. recently launched its 4TN86DHT engine series, featuring three models designed to meet diverse industrial equipment application requirements. The new lineup includes the base 4TN86DHT-XNYEM model, alongside optional power pack models, such as the 4TN86DHT-XNYEM-PIH-P and the 4TN86DHT-XNYEM-PIH-S.
The 4TN86DHT series features robust four-cylinder, 2.09-liter (127 cubic inch) displacement engines, delivering 59 horsepower (44.0 kW) output while maintaining increased fuel efficiency at 3.37 gallons per hour (12.8 liters/hour). Operating at a rated speed of 2,500 RPM, the engines utilize turbocharged and intercooled aspiration, combined with common-rail direct-injection fuel delivery, for increased performance across a wide range of operating conditions.
Built on Yanmar’s TNV design foundation, these engines incorporate advanced Final Tier 4 and EU Stage V emission control technology without compromising reliability and torque, according to the company.
“The 4TN86DHT represents our commitment to delivering sustainable solutions that meet tomorrow’s environmental standards today,” said Frank Johnson, division manager, industrial engines division. “We’ve proven that operators don’t have to sacrifice performance for compliance. Through advanced vibration reduction and high-strength construction, these engines handle demanding applications while our combustion technology delivers better fuel control, reduced emissions and improved efficiency to help meet our customers’ needs.”
The additional models with power packs include the 4TN86DHT-XNYEM-PIH-P with a pusher fan and a 4TN86DHT-XNYEM-PIH-S with a puller fan. A puller or pusher fan combined with the diesel engine helps improve cooling efficiency. Puller fans benefit from equipment running at lower speeds and higher temperatures, while pusher fans are more effective at higher speeds. These models are available for different equipment designs depending on the application.
As with all Yanmar engines, industrial equipment manufacturers who choose the 4TN86DHT can benefit from Yanmar’s engineering services which will collaborate to customize engines according to the specific machinery requirements and product vision of the original equipment manufacturer (OEM).
The 4TN86DHT-XNYEM and models with power packs are available for purchase today.
