Abstract

A method for testing an ignition device (90) associated with a cylinder (26) of a dual fuel engine is disclosed. When the dual fuel engine is operating in a liquid fuel mode, an injection timing of the ignition device (90) is first retarded to a timing that is later than an injection timing of the main injection system. Then, the injection timing is advanced to a timing that is earlier than the injection timing of the main injection system. A combustion parameter is measured for the retarded and advanced injection timings, and it is determined based on a comparison of the measurements whether the ignition device (90) is functional. When the injection devices of all cylinders are functional, operation of the dual fuel engine is switched from the liquid fuel mode to the gas mode.
