The method of controlling combustions of an engine having three or more pistons of cylinders per crankshaft includes causing simultaneous combustions of two cylinders among the three or more cylinders, the two cylinders having the same crank phase angle, causing a combustion of at least one -other cylinder, and in the process of said combustion offsetting a crank phase angle by a first crank phase angle, and repeating from the combustions of the first two cylinders further offsetting the crank phase angle by a second crank phase angle from the first crank phase angle.
