... emissions and low thermal efficiency, particularly at low loads. The objective of this study is to achieve dual-fuel engine thermal efficiency and emissions better than those of a diesel mode while utilizing alternative fuels. A new approach consisting of a combined strategy using dimethyl ether (DME...

... geometries and nanostructured thermoelectric materials have been investigated over the last decades in order to improve the thermal efficiency of the TEGs. In this paper, a numerical study on the performance analysis of a nanomaterial-based (i.e., p-type leg composed of BiSbTe nanostructured bulk alloy and n...

... are determined using ASTM standard test methods. Among all blends, the D+50AN showed a maximum improvement of about 5.9% in brake thermal efficiency (BTE) and remarkable reduction in NO x , smoke, HC, and CO as 15.6%, 22.34%, 31.82%, and 13.79%, respectively, at maximum rated power output. The compression...

..., the injection timing is retarded by 2.2 °CA and the injection duration is extended by 0.8 °CA. Accordingly, the ignition delay and the combustion duration are extended by 0.7 °CA and 4.0 °CA, respectively. The cylinder peak pressure is decreased by 5.4%. As a result, the effective thermal efficiency...

... efficiency is found to be more than that of the generator efficiency on the power output while it is reverse in the case of thermal efficiency. It is also found that there is an optimum relation among the various heat capacitance rates at which the cycle attains the maximum performance. 30 08 2003...
