Fuel System - N16: Notes

The 4-cylinder N12/N16 gasoline engine works with an individual-cylinder, fully sequential fuel injection. The individual-cylinder, fully sequential fuel injection has the following advantages:

• Optimized fuel preparation for each individual cylinder
• Adaptation of the fuel injection period to suit the engine's operating condition (engine speed, load, temperature)
• With changing loads, cylinder-selective injection correction (during an intake stroke, the fuel injection period can be corrected by a later injection, an extension or shortening)
• Cylinder-selective cutoff (e.g. when an ignition coil is defective) is possible
• Diagnosis of each individual fuel injector is possible.
