Circuit monitoring state of combustion in internal combustion engine |
| 摘要 |
The circuit includes a circuit (5) that applies a polarisation potential to the spark plug and a circuit (21) to detect ionisation current in the cylinder. A signal processing circuit (24-27) produces a decision signal if the ionization current levels indicate detonation is occurring in the engine.
