Cummins gets to work on natural gas engine

Cummins Jamestown Engine Plant has begun limited production of a new 12-liter Cummins Westport natural gas engine — the ISX12 G. 
“We are first to market with this heavy-duty, spark-ignited on-highway natural gas engine,” said company spokesman Jon Mills. “Natural gas is a growing part of the business, but still small in terms of Cummins’ overall business.”
Manufacturing on the engine began in April.
According to Cummins, the ISX12 G operates on 100 percent natural gas, which can be carried on the vehicle in either compressed natural gas (CNG) or liquefied natural gas (LNG) form.
Mills said natural gas engines accounts for about one percent of overall engine sales. But over time, the company anticipates strong market interest could present a significant opportunity for the ISX 12G and the Jamestown plant. He said the plant has already added jobs this year, and may add more. The headcount on the added positions was not disclosed. 
“As far as natural gas, Cummins has been a leader in natural gas engines for decades and in North America, we have about 90 percent of the market share through our Cummins Westport joint venture,” he said. “The growth of the natural gas business is dependent on the price differential between diesel fuel and natural gas, as well as the number of fuel stations nationwide.” 
Cummins anticipates that natural gas engines will account for 5 to 10 percent of the on-highway market over the next five to 10 years, and considers itself well-positioned if demand is greater. Cummins is also investing in off-highway natural gas engine opportunities.
