    Question is Not If But When the Demand Will Materialize
    As Big-Engine Customers See Need for More Public Fueling

    Cummins has placed development of its 15-liter spark ignition engine on hold for at least six months, having decided in December that it’s not sure when the market for the 450-horsepower dedicated natural gas product will materialize.

    “Around mid-year we’ll take a look at it again,” says Roe East, on-highway natural gas business GM at Cummins, Inc. The firm remains committed to natural gas, he says.
    The diesel-fueled Cummins ISX15 is the basis for the spark-ignition 15-liter engine to come.

    The difference from the now commercial, 11.9-liter ISX12 G with Cummins Westport and the new engine – call it the ISX15 G – is the public infrastructure requirement, he says.

    “Reality and Confidence in Reality’

    “My gut feeling is that most of the people buying the 12-liter today have dedicated fueling,” East says – or run regular point-to-point routes. “The customer base demanding the 15-liter engine is more likely to run variable routes,” he says. “They need to be confident that they can stop at a public station.”

    Infrastructure for both liquefied natural gas and compressed natural gas is being built. But according to East, “Reality and confidence in reality are two different things.”

    That’s why the six-month program hiatus could be extended another six months, he told F&F, when Cummins revisits the issue in mid-2014
