The CDI control unit (N3/9) regulates the injection quantity at every operating condition. To do this, the CDI control unit reads in information from the following components:
- Oil temperature sensor (B1) (except model 461)
- Oil sensor (oil level, temperature and quality) (B40) (model 461)
- Left hot film mass air flow sensor (B2/6) and right (B2/7) (except model 461)
- hot film mass air flow sensor (B2/5) (model 461)
- Rail pressure sensor (B4/6)
- Charge pressure sensor (B5/1)
- Camshaft Hall sensor (B6/1)
- Coolant temperature sensor (B11/4)
- Charge air temperature sensor (B17/8)
- Pressure sensor downstream of air filter (B28/5) (except model 463) or pressure sensor downstream of air filter, right cylinder bank (B28/5) (model 463)
- Accelerator pedal sensor (B37)
- Crankshaft Hall sensor (B70)
- CC [TPM] with variable speed limiter switch (S40/4) (model 203) or CC [TPM] switch (S40/4) (model 164, 209, 211, 219, 221, 251, 463)
After evaluating the input signals, the CDI control unit controls the injection quantity for each cylinder according to the injection sequence. In order to adapt the injection quantity the actuation time of the fuel injectors (Y76) is extended or shortened via the CDI control unit while taking account of the rail pressure. The injection quantity is divided into a preinjection quantity, main injection quantity and a post injection quantity.
