Abstract
A method for operating a dual-fuel engine. Embodiments include receiving sensor input information, including information representative of a temperature of the engine. A first fuel, optionally diesel fuel, and a second fuel that is different than the first fuel, optionally natural gas, are supplied to the engine during a start mode when the engine temperature is below a normal operating temperature range. The first and second fuels can be supplied to the engine during a run mode when the engine temperature is within the normal operating temperature range.
