The article examines the peculiarities of evaluating the vehicular engine harmful emissions in different heating modes when using thermal development system of the catalytic converter within phase-transitional thermal accumulators. The system under review uses thermal energy from different sources of the vehicular engine during its operation to accumulate it in thermal accumulators. The functional scheme of thermal development of the “vehicular engine - thermal accumulator - catalytic converter” system is shown. The functional scheme takes into account fuel consumption, mechanical energy and harmful emissions when operating the vehicular engine equipped with the exhaust gases cleaning system and the thermal development system with phase-transitional thermal accumulator.
