2. Ignition sequence
2.1 Ignition sequence and crankstar
The second key parameter in multi-cylinder engine architecture is the choice of ignition sequence. The sequence of cylinder ignitions during an engine cycle is a decisive parameter for characterizing the excitation of internal combustion engines. For standard configurations up to 6 cylinders in-line and 12 cylinders V-shaped, the number of possible ignition orders is still reasonable and sufficiently covered in the literature. However, this number increases proportionally with the factorial of the number of cylinders, making the selection of an appropriate ignition order increasingly difficult as the number of cylinders increases. Table 3 summarizes the formulas to be used to determine...
