VANCOUVER, BC – Westport Innovations Inc. (TSX:WPT / NASDAQ:WPRT), engineering the world's most advanced natural gas engines and systems, today is unveiling its newest proprietary technology that has shown a significant breakthrough on dual fuel performance, Westport gas enhanced methane diesel (Westport GEMDi™). Westport GEMDi technology enables engine original equipment manufacturers (OEMs) to offer a fully integrated, high performance engine optimized for dual fuel operation.
Westport GEMDi technology has been co-developed with Tata Motors on their next generation 5L engine that is targeted for medium-duty trucks and buses in India. This technology provides fuel flexibility, ideal for regions where natural gas infrastructure is emerging, such as India, and is designed to meet Euro IV and V emissions standards.
"Westport GEMDi is an innovative, low-cost, fully integrated solution with advanced dual fuel performance," said Thomas Rippon, Executive Vice President of Westport. "Westport GEMDi is the right solution for engine OEMs, such as Tata, 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," said Rajendra Petkar, Head Power Systems Engineering, ERC of Tata Motors. "With Westport GEMDi technology, we are pioneering the next generation natural gas product that will be efficient, economic, and flexible in fuel, enhancing customers' driving range."
A dual fuel engine typically relies on conventional diesel engine hardware. Modifications to the base diesel engine allow operation with natural gas fuel. Under dual fuel operation, natural gas is introduced at low pressure and mixed with the intake air. Diesel fuel is introduced directly into the combustion chamber near the end of compression stroke and is used to ignite a lean mixture of natural gas and air (i.e. no spark plugs are required). Since dual fuel engines are closely configured based on a diesel engine, it allows them to provide higher performance (torque and power) and efficiency on natural gas fuel as compared to a traditional spark ignited natural gas engine. Based on Westport analysis, typically a dual fuel vehicle would operate at about 60% average fuel substitution ratio (i.e. fraction of total fuel energy contributed by natural gas), with the remaining coming from diesel fuel. Higher fuel substitution ratios are possible through improved engine design and control. Dual fuel engines are capable of reverting back to 100% diesel operation over the entire engine operating range if required.
Tata's 5L natural gas engine featuring Westport GEMDi was displayed at India's Auto Expo in New Delhi, India, from February 7 to 11. Upon successful completion of the development phase, commercialization with Tata Motors is expected to follow, with Westport supplying key natural gas engine components.
India is one of the world's largest truck and bus markets. Its total annual medium- and heavy-duty truck and bus sales are projected to reach over 289,000 units in 2014 and 478,000 units in 2022, according to the Natural Gas Trucks and Buses report published by Navigant Research at the end of 2013. Tata's 5L engine with Westport GEMDi technology is primarily targeted for medium-duty trucks and buses running on dedicated routes in India. According to Navigant Research and Westport analysis, India's medium-duty natural gas truck and bus population is projected to be over 12,000 units in 2014, representing a 5% market penetration, and is expected to quickly grow to more than 60,000 units in 2022, reaching a 15% market penetration in the medium- and heavy-duty truck and bus market.
