Westport Promotes New Dual Fuel and Spark-Ignition Engines
Targeting Enormous Potential Market with India’s Tata Motors
Westport is promoting two new engines, developed with India’s Tata Motors, targeting “one of the world’s largest truck and bus markets.” The first is a 5-liter natural gas-diesel dual fuel engine using a proprietary technology Westport calls GEMDi, for gas enhanced methane diesel. The second is a 3.8-liter turbocharged spark-ignition employing an engine management system dubbed Westport WP580. updated February 18
GEMDi dual fuel provides fuel flexibility, Westport says, “ideal for regions where natural gas infrastructure is emerging, such as India.” It is designed to meet Euro IV and V emissions standards.
GEMdi provides “an innovative, low-cost, fully integrated solution with advanced dual fuel performance,” Westport executive VP Thomas Rippon said in a release. It “is the right solution for engine OEMs, such as Tata,” he said, “that are committed to offering sustainable products utilizing natural gas as a primary fuel, while maintaining diesel-like performance and efficiency.”
“Natural gas trucks and buses are gaining traction in India as national natural gas fueling infrastructure continues to develop,” Tata power systems engineering chief Rajendra Petkar says in the Westport announcement. “We are pioneering the next generation natural gas product that will be efficient, economic, and flexible in fuel, enhancing customers’ driving range,” he said.
“The elements of this technology in principle could be applied to other engines too,” says Westport technology R&D director Sandeep Munshi. The 5-liter engine being offered as a GEMDi dual fuel is part of a larger family of common rail diesel engines, he told F&F.
The 3.8-liter spark-ignition engine with Westport WP580 EMS is aimed at light duty applications.
“India has one of the largest natural gas light-duty vehicle fleets in the world,” Petkar said. “We see an enormous opportunity.”
“The Westport WP580 offers breakthrough price, performance, and flexibility for OEMs allowing them to use this advanced technology even in cost-effective markets such as China and India,” Rippon said.
5.7-Liter Spark Later this Year
The WP580 EMS is designed to support numerous engine configurations, Westport says. Its combustion control technology “can optimize the engine for class leading fuel economy, torque, and power while meeting existing and future emissions and onboard diagnostic requirements.” It is to be applied to Tata’s 5.7-liter engine later this year.
Citing work by Navigant Research, Westport cites India as “one of the world’s largest commercial vehicles markets” – annual light-duty vehicle fleet and commercial sales are projected to exceed 204,000 units in 2014, while medium- and heavy-duty truck and bus sales will top 289,000 units.
