Abstract
Described herein is a closed-loop electronic control system for controlling combustion in a diesel engine operating with highly premixed combustion, in which an injection system is designed to obtain at least two injections of fuel per engine cycle, the injections comprising at least one pilot injection and a subsequent main injection. The system is provided with sensors designed for measuring or calculating quantities characteristic of the process of fuel combustion, and a closed-loop control block, which provides a control of the modality of fuel injection based upon the measured or calculated value of the quantities by regulating at least one of the following parameters: the distance in time elapsing between the execution of the pilot injection and the main injection; and the amount of fuel injected by means of the pilot injection.
