A HEV system with engine exhaust aftertreatment and exhaust heat recovery system is simulated under various scenarios, including warm and cold start. Optimal strategies are derived from Pontryagin Minimum Principle (PMP). The concept of fuel equivalent of thermal energy variations – similar to the equivalence factors for battery energy of standard Equivalent Consumption Minimization Strategy (ECMS) – is introduced. The PMP-based strategies are compared with a heuristic, rule-based strategy. The benefits in fuel economy and reduction of pollutant emissions that are obtained for several scenarios are very promising. 4 Oil and Gas Science and Technology 67 ARTICULO Merz, F. 53161 Sciarretta, A. 43442 Dabadie, J.C. 53162 Serrao, L. 53163 187682 187682 0 0 0 0 255501 BAAB BAAB 2026-03-06 200059824 0 200059824 2026-03-06 00:17:39 2026-03-06 ARTICULO
