The concept of the paper stems from the premise that the process of “heat release” in engines involves in essence the evolution and deposition of exothermic energy generated by combustion-events that can be governed promptly by a feedback, adaptive micro-electronic control system. The key to its realization is the principle of
DISC (Direct Injection Stratified Charge) engine, implemented by a multi-jet system. The background and the salient features of such a system, referred to as a
CCE (Controlled Combustion Engine), have been described in a companion paper (SAE
951961). Presented here are fundamental aspects of the model of the exothermic process and the intrinsic properties of its control system.
