A V-type 4-stroke internal combustion engine having 20 cylinders, having a counterclockwise or clockwise direction of rotation, comprising a crankshaft with a torsional vibration damper and a flywheel arranged on the crankshaft, wherein the crankshaft has crank throws forming a crank star, wherein in each case the piston rods of the two cylinders of a V-segment are connected to the same crank throw, wherein the crank throws C1 to C10 have one of the following angular sequences in the direction of rotation of the engine when seen from the side of the flywheel, with the crank throws numbered as C1 to C10 when starting from the side of the flywheel: (i) C1-C9-C4-C6-C3-C10-C2-C7-C5-C8, (ii) C1-C8-C5-C7-C2-C10-C3-C6-C4-C9, (iii) C1-C9-C5-C7-C3-C10-C2-C6-C4-C8, (iv) C1-C9-C7-C3-C6-C10-C2-C4-C8-C5, (v) C1-C7-C5-C8-C2-C10-C4-C6-C3-C9, (vi) C1-C9-C7-C3-C5-C10-C2-C4-C8-C6, (vii) C1-C6-C8-C4-C2-C10-C5-C3-C7-C9, (viii) C1-C5-C8-C4-C2-C10-C6-C3-C7-C9, (ix) C1-C8-C4-C6-C2-C10-C3-C7-C5-C9.
A V-type 4-stroke internal combustion engine having 20 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 10 crank throws forming a crank star, wherein in each case piston rods of two cylinders of a V-segment are connected to a same crank throw, wherein crank throws C1 to C10 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 C10 when starting from the side of the flywheel:
A firing sequence controller or software for a V-type 4-stroke internal combustion engine with 20 cylinders, wherein the engine cylinders are numbered A1 to A10 and B1 to B10, and wherein the direction of rotation and the cylinder numbering is defined in accordance with DIN ISO 1204, the firing sequence controller or software implementing at least one of the firing sequences,
A method for operating a V-type 4-stroke internal combustion engine with 20 cylinders, wherein the engine cylinders are numbered A1 to A10 and B1 to B10, wherein the direction of rotation and the cylinder numbering is defined in accordance with DIN ISO 1204, wherein the engine is operated with at least one of the firing sequences,
