摘要： A system and method for monitoring the temperature in a vehicle after-treatment system is provided. The system includes one or more temperature sensors positioned in the vehicle after-treatment system and an electronic control unit (ECU) configured by programming instructions encoded in computer readable media to execute a method. The method includes monitoring the temperature presented by the one or more temperature sensors, executing a lower oxygen combustion strategy for a slower exothermic reaction when the temperature exceeds a first threshold level, and deactivating the lower oxygen combustion strategy when the temperature drops below a second threshold level.

摘要： Aspects of the subject disclosure may include, for example, an emission control system that includes an emission control device having a plurality of passages to facilitate emission control of an exhaust gas from a vehicle engine. A controller determines a resonant frequency of a coil and generates a control signal to control induction heating of the emission control device based on the resonant frequency of the coil. An alternating current (AC) source responds to the control signal by selectively generating a power signal to the coil to facilitate the induction heating of the emission control device via the coil.

摘要： An object of the present invention is to optimally control a recirculation amount of exhaust gas flowing to an engine that includes an exhaust heat recovery device in a main exhaust pipe thereof and performs exhaust gas recirculation from downstream of the exhaust heat recovery device. An engine control device includes an exhaust heat recovery device, an exhaust gas recirculation pipe, an exhaust gas temperature acquisition unit, and an exhaust gas recirculation amount control unit. The exhaust heat recovery device is provided in a main exhaust pipe of an engine and recovers heat from exhaust gas. The exhaust gas recirculation pipe is branched from the main exhaust pipe downstream of the exhaust heat recovery device and recirculates exhaust gas to the engine. The exhaust gas temperature acquisition unit acquires an exhaust gas temperature downstream of the exhaust heat recovery device. The exhaust gas recirculation amount control unit controls a recirculation amount of exhaust gas flowing through the exhaust gas recirculation pipe based on at least the exhaust gas temperature.

摘要： An improved electrocatalytic system utilizes an Organic Rankine cycle system to take advantage of exhaust fume heat to convert a working fluid to steam used in a steam expander to generate electricity. The generated electricity is then used in electrolyzing water to produce hydrogen gases used as a supplemental fuel in an internal combustion (IC) engine. Thereby, the improved electrocatalytic system provides an efficient, less costly and retrofittable system for reducing harmful emissions and fossil fuel consumption in vehicles.
