Abstract
Methods and systems are provided for actively heating pistons in combustion chambers to decrease a torque imbalance in an engine. In one example, a method for operation of an engine includes determining a variation between compression ratios in a first combustion chamber and a second combustion chamber and operating a piston heating system to apply a targeted amount of heat to a first piston assembly based on the variation between the compression ratios, the first piston assembly including a first piston positioned within the first combustion chamber.
