The company’s newest proprietary technology is the first generation of enhanced spark-ignited (ESI) natural gas system, and is designed to provide vehicle and engine original manufacturers (OEMs) with a “downsized” NGV solution that is cost competitive while providing similar levels of power, torque, and fuel economy to a larger diesel engine. Using 100% dedicated natural gas (CNG or LNG), it optimizes the combustion and thermal efficiencies of the engine by taking advantages of the positive properties of natural gas.
Developed to meet the highest level of OEM quality standards, Westport’s new combustion system and components have been undergoing testing and offer ready integration into OEM applications globally. Its durability and reliability levels are expected to meet an OEM’s extensive engine development program. The Westport™ ESI combustion system is targeted at sub 9L engines for Class 6 and 7 trucks applications and is also adaptable for sub 2L applications for use in automotive and non-automotive applications.
“As gasoline and diesel engines progress, it is critical that OEMs offer natural gas engines that retain their expected performance while providing the environmental and economic benefits of natural gas,” said Jack Keaton, Westport VP of Global Spark Ignited Direct Injection. “Westport is taking its technology leadership to the next level by introducing a long term technology solution that allows improvements in engine performance and fuel economy, thus offering highly attractive operating costs and low emissions profile.”
Expected to meet the most rigorous emissions levels, Westport ESI is designed to meet the latest emission regulations including Euro VI and U.S. EPA 2014 standards. Westport is currently in various stages of development and negotiation with several vehicle and engine OEMs for ESI applications in medium-duty truck and automotive applications.
