Injection twice/combustion
WARNING: This page is about a different car, the 2005 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
Before the camshaft position has been detected, injection will take place semi-sequentially at 180 intervals. This means two cylinders at a time in the following order:
- Cylinders 1 and 4.
- Cylinders 2 and 3.
Each injector injects fuel once per crankshaft rotation and this means that the basic duration must be divided by two.
