Westport Innovations and India’s Tata Motors Limited have launched a new spark-ignited (SI) natural gas 3.8L turbocharged engine featuring the Westport WP580 Engine Management System (EMS). Designed to support many engine configurations, the Westport WP580 EMS is also scheduled to be applied to Tata's 5.7L engine targeting medium-duty applications in late 2014.
"By combining our unique technology and Tata's leadership in India's commercial vehicles market, we are able to introduce new natural gas products and target the mainstream transportation markets in one of the world's fastest growing markets for natural gas vehicles," said Thomas Rippon, executive vice president of Westport. "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."
The Westport WP580 EMS is a highly configurable system that has been specifically developed for spark ignited, dedicated natural gas engine applications and can be integrated with a wide range of proprietary Westport fuel system components for flexible vehicle design and production, according to the companies. Its advanced 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. Westport has also set a new benchmark with the WP580, with industry leading price performance and value, allowing natural gas vehicles to be competitively priced with petroleum-based vehicles.
Key features of the Westport WP580 EMS include:
- Unique engine control strategies: The Westport WP580 EMS is specifically tailored to maximize the performance of the base engine. Key benefits include reduced fuel consumption and emissions, increased vehicle load carrying capabilities with launch torque, and integrated vehicle functionality.
- Compatible and cost-effective design with natural gas components: With proven OEM track record, these natural gas components such as electronic control units and spark plugs have been fully validated for the application and manufactured to automotive industry quality standards resulting in high levels of reliability and lower cost.
- Meeting current and future emissions profile: The system is designed to meet Euro VI emission standards.
