It's not true. For a modern eight-cylinder internal combustion engine with a flywheel and a balanced, counterweighted crankshaft, there's no significant pulsation present in the output power train. If there were, it would quickly destroy the transmission and rear differential. There are a number of excellent reasons to suppress any significant pulsation in the power from an ICE, and the flywheel is the primary way to accomplish this.
