Adaptive Engine Control Unit with Feedback Knock Signal

With application of modern programmable engine control units (ECU) an opportunity to develop more complex control algorithms appeared. Self-learning systems have been designed which adapt different engine controlling parameters in accordance with the required optimums.

Below is a description of the ECU, which supports maximum power (minimum fuel consumption) supplying the optimal spark advance (SA) in each cylinder with minimum level of knock cycles, taking account of the age, mileage and type of petrol.
