▼a Engine efficiency improvement can help combustion powertrains, which include conventional, hybrid, and plug-in hybrid systems, to meet the strict emissions standards and the increasing demand from customers for performance, drivability, and affo |

▼a This thesis identified opportunities to improve efficiency in internal combustion engines by high EGR dilution SI combustion by using thermodynamics-based approaches. This goal has been achieved by using fuel reforming in a thermodynamically-fav |

▼a The concept and the system to use one cylinder to serve as a committed fuel reformer without spark ignition is first demonstrated. The committed in-cylinder reformer engine system achieves 8% brake thermal efficiency improvement through EGR and |

▼a The novel catalytic EGR-loop reforming integrated engine system was designed and tested. The experiments and thermodynamic equilibrium calculations reveal that the suppression of H2 and CO caused by the enthalpy limitation could be countered by |

▼a The results demonstrate fuel injection during NVO can extend the dilution limit, improve brake specific fuel consumption (BSFC), and reduce CO and NO x emissions on the engine modified with the capability of variable intake and exhaust valve tim |
