Abstract: A method for jumping cylinder deactivation (“CDA”) modes to avoid a primary powertrain resonant frequency in a six-cylinder diesel engine-powered machine comprises operating an engine between an idled condition and a first engine speed limit in one of a two-cylinder CDA mode or a four-cylinder CDA mode. The method operates the engine between the first engine speed limit and a second engine speed limit in a three-cylinder CDA mode. The first engine speed limit is an engine speed below which the two-cylinder or four-cylinder CDA mode causes the machine to operate below a primary powertrain resonant frequency and also above which the three-cylinder CDA mode causes the machine to operate above the primary powertrain resonant frequency, thus avoiding the primary powertrain resonant frequency during operation. A CDA mode can be selected above the second engine speed limit to operate the machine above the primary powertrain resonant frequency.
