TL;DR: In this article, the effect of exhaust gas recirculation (EGR), compression ratio and boost pressure on cyclic variation was investigated by means of both experiments and simulation for a port fuel injection (PFI) engine.

TL;DR: In this article, an experiment was conducted on a turbocharged direct injection diesel engine, and oxygen-enriched and EGR techniques were used to produce lower NO-smoke emission than the unmodified engine under the same fuel supply rate curve and fuel supply quantity.

TL;DR: In this article, an analytical network process (ANP) is applied for measurement of the dependency among the strategic factors, which can help engineer determine their decisions, and they found that thermoelectricity technology is the most suitable method to recovery waste energy in future and the ANP technique is useful as a decision judgment tool.

TL;DR: The optimized thermo-economic approach proposed here improves the accuracy and reliability of conventional early-stage engineering design and assessments, which can be extended to other similar thermal systems that involve heat exchangers integration in similar applications.

TL;DR: In this article, a 3D numerical model for the integration structure of TEG and three-way catalytic converter (TWC) is presented, showing that the uniform temperature distribution and high output power can be obtained with TWC placed in the rear of heat exchanger.
