ICE Vehicle Challenge toward Zero Emissions: Future Technology Harmonization in Electrified Powertrain System 2019-01-2217
BEVs and FCEVs are getting more popular since they can contribute to reduce the concern of global warming and the environmental pollution, especially in urban area, they do not emit exhaust gas emissions. In other words, the expectation of a Zero emission society increases. On the other hand, HEVs and PHEVs which have internal combustion engines have realized a drastic reduction of fuel consumption and exhaust gas emissions thanks to optimal power management of the motor and the engine. They already achieved a great contribution toward CO2 reduction in global level. In order to realize emission free society, this research addresses “Zero-Emissions challenge” of PHEV exhaust gas emissions (to be able to consider equal to BEV in well to wheel), contributing to the global environment pursuing new value for the internal combustion engine. In this investigation, the possibility of the emissions achievement of the 1/10 level of SULEV30 was confirmed by harmonizing new technologies such as optimized combined control of engine and motor, catalyst development, and model based prediction control, which achieved reduction of emissions and catalyst deterioration at the same time.
