Cummins Westport Co., Ltd. announced that it will develop ISB6.7G, 6.7 liters of medium-sized natural gas engines to meet the growing demand for the automotive market. These vehicles are low-cost, cleaner, and use rich natural gas as fuel.
At the same time, our company has established an advanced CAD/CAM/CAE system and a centralized management system to realize the sharing and high-speed transmission of information resources within the company, which greatly improves the integration process of mold design and processing, and provides a variety of high, precise, The design and manufacture of tip molds provide a strong guarantee. The company produces 600 sets of molds annually.

The ISB6.7G natural gas engine to be developed will use the Cummins ISB 6.7 litre diesel engine as the main engine, using the Cummins Westport spark plug ignition (SI) stoichiometric cooling exhaust gas recirculation technology. The exhaust gas aftertreatment is a simple, maintenance-free cost of three. The meta catalyst achieves the use of compressed natural gas in the engine, but can be stored in the form of LNG and compressed natural gas. ISB 6.7G is expected to achieve production in 2015 and meet the emission standards of the EPA and the California Air Resources Board.
Jim Arthurs, president of Cummins Westport, said: “There are already 16,000 units of the 8.9-liter ISLG engine at West Port of Cummins. The 11.1-liter ISX12G engine will also start production in 2013. The development of the ISB 6.7G engine will further improve the product line of high-performance natural gas engines. For customers to choose natural gas engines for vehicles to provide a wider choice of space."
