The present invention comprises a V-type 4-stroke internal combustion engine with 16 cylinders, having a counter-clockwise direction of rotation, comprising a firing sequence controller that fires the cylinders A1 to A8 and B1 to B8 in at least one of the following firing sequences, wherein the direction of rotation and the cylinder numbering is defined in accordance with DIN ISO 1204: a) A1-B7-A2-B6-A3-B5-A5-B1-A8-B2-A7-B3-A6-B4-A4-B8 b) A1-B7-A2-B6-A6-B4-A5-B1-A8-B2-A7-B3-A3-B5-A4-B8 c) A1-B7-A2-B5-A4-B3-A6-B1-A8-B2-A7-B4-A5-B6-A3-B8 d) A1-B4-A4-B6-A3-B7-A2-B8-A8-B5-A5-B3-A6-B2-A7-B1 e) A1-B5-A5-B3-A6-B2-A7-B1-A8-B4-A4-B6-A3-B7-A2-B8. and further shows a corresponding engine having a clockwise direction of rotation, comprising a firing sequence controller that fires the cylinders A1 to A8 and B1 to B8 in at least one of the following firing sequences: a) B1-A7-B2-A6-B3-A5-B5-A1-B8-A2-B7-A3-B6-A4-B4-A8 b) B1-A7-B2-A6-B6-A4-B5-A1-B8-A2-B7-A3-B3-A5-B4-A8 c) B1-A7-B2-A5-B4-A3-B6-A1-B8-A2-B7-A4-B5-A6-B3-A8 d) B1-A4-B4-A6-B3-A7-B2-A8-B8-A5-B5-A3-B6-A2-B7-A1 e) B1-A5-B5-A3-B6-A2-B7-A1-B8-A4-B4-A6-B3-A7-B2-A8.
A V-type 4-stroke internal combustion engine with 16 cylinders, having a counter-clockwise direction of rotation, comprising a firing sequence controller that fires the cylinders A1 to A8 and B1 to B8 in at least one of the following firing sequences, wherein the direction of rotation and cylinder numbering is defined in accordance with DIN ISO 1204:
A V-type 4-stroke internal combustion engine with 16 cylinders, having a clockwise direction of rotation, comprising a firing sequence controller that fires the cylinders A1 to A8 and B1 to B8 in at least one of the following firing sequences, wherein the direction of rotation and cylinder numbering is defined in accordance with DIN ISO 1204:
A V-type 4-stroke internal combustion engine having 16 cylinders, having a counter-clockwise or clockwise direction of rotation, comprising a crankshaft, a torsional vibration damper and a flywheel arranged on the crankshaft, wherein the crankshaft has 8 crank throws forming a crank star, wherein in each case piston rods of two cylinders of a V-segment are connected to the same crank throw, wherein the crank star is of a lengthwise symmetric or lengthwise quasi-symmetric type, wherein the crank throws C1 to C8 have one of the following angular sequences in the direction of rotation of the engine when seen from a side of the flywheel, with the crank throws numbered as C1 to C8 when starting from the side of the flywheel:
