Cummins Kicks Off Natural Gas Theme at MATS With New Engine

LOUISVILLE, Ky. — Engine maker Cummins Inc. told reporters here that the company is moving forward with spark-ignition natural gas engines with a heavy-duty 12-liter engine now, and a 15-liter model in two or three years.

The engines will work with compressed or liquefied natural gas or biomethane, the independent Columbus, Ind., manufacturer said here on the eve of the Mid-America Trucking Show, which officially opens on Thursday.

Cummins, which will also offer 6.7- and 9-liter engines for medium-duty trucks, said it will supply natural gas engines made by its joint venture with Westport Innovations to most North American heavy-duty truck manufacturers, making natural gas propulsion an early theme of MATS.

Cummins also said it will update its diesel engines for next year, incorporating both onboard diagnostics and lower emissions of greenhouse gases.

The changes are necessary to comply with federal emissions regulations and the company said it would be better to batch both changes together rather than spread them out over two years.

Cummins, the market share leader in North American heavy-duty engines, also unveiled a new oil filter featuring nanotechnology.
