This study applies the L9 orthogonal array of the Taguchi method to find out the best hydrogen injection timing, hydrogen-energy-share ratio, and the percentage of exhaust gas circulation (EGR) in a single DI diesel engine. The injection timing is controlled by an electronic control unit (ECU)...

This study designed the processing parameters of the flat-plate collector based on the orthogonal arrays. Processing parameters of a flat-plate collector are the key factors affecting its performance. These parameters include the collector tube material, endothermic plate material, number of...

Castor beans are one of the world's top ten oil crops, with approximately 50% castor oil and 50% castor meal being obtained after a two-stage pressing process (cold and hot pressing). Nevertheless, castor meal still contains a significant amount of residual oil, due to the mechanical limitations...

The efficiencies of coal-fired CHP (combined heat and power) plants used in the district heating systems of China were analyzed with a thermodynamic model in the Hysys program. The influences of four parameters were evaluated by the Taguchi method. The results indicated that the extraction steam...
