Abstract: Compression ignition engines are an essential part of automotive transportation and even marginal improvements can bring significant benefits in terms of costs and environmental impact. Exhaust gas recirculation (EGR) is used on an extensive scale for these power units, and monitoring their performance continuously would ensure improved procedures for ensuring longer lifetime and better efficiency. Within this context, the current work evaluated the heat transfer performance of a cooled EGR module in view of developing a dedicated sensor. This device should provide enough information on heat exchange and flow performance of the recirculation unit, while being able to integrate the acquired information within the vehicle communication network. Apart from the minimal requirement of identifying failures, the new component goes beyond current virtual-sensor based approaches and will ensure better efficiency of EGR valves and more precise maintenance intervals

Abstract: A new solar-absorbing Façade Panel has been developed in this government-funded project to cope with the urgent needs on building sustainability research, in particular the renewable energy applications. In this paper, two related inventions, namely the water-filled glazing with submerged heat exchanger and the heat-pipe-ring embedded curtain walling, are described. With the use of validated self-developed simulation programs, the energy performance of the glazed and opaque areas of the panel are assessed separately. Performance comparisons were made with the conventional curtain walling. The findings support that with an appropriate coverage of the new Façade Panel on the building envelope, as well as the appropriate area ratio of the glazed to opaque surfaces, this innovative Façade is able to reduce significantly the solar transmission and to generate adequate hot water with promising thermal efficiency.
