Cummins unveils natural-gas powered engine

Cummins is introducing a 15-liter natural gas engine that the company calls a “game changer” as an option to traditional diesel power trains for heavy-duty trucking.

The Columbus-based engine manufacturer announced the new engine yesterday. The engine is expected to offer up to 500 horsepower and 1,850 foot pounds of torque, but still weigh 500 lbs less than comparable diesel engines. It won’t require Selective Catalytic Reduction to meet California or Environmental Protection Agency emission standards.

Company officials say the new engine is also the basis for the hydrogen internal combustion engine currently being tested.

The company says that when powered with renewable natural gas, using methane collected from organic waste as the primary fuel source, the system can produce net greenhouse gas emissions at or below zero.
