| In this study, some important physical and mechanical properties of the hawthorn and the effect of moisture on them were investigated. The effect of moisture at two levels (64.01% and 70.1%, w.b.) on the geometric dimensions (length, width, thickness, arithmetic mean diameter, geometric mean diameter, degree of sphericity, surface area, projected area, criteria projected area, mass, volume and the apparent), true density, porosity, coefficient of static friction and coefficient of rolling on three levels (wood, glass and galvanized) and mechanical properties obtained by impact testing machine using a randomized factorial design was evaluated by software SPSS18. Results indicate that moisture has an effect on the physical properties of the hawthorn. The... |

| In this study, the effect of using biodiesel – derived from waste cooking oil – and exhaust gas recirculation (EGR) on engine performance and emissions of a single cylinder 4-stroke engine has been investigated. Three engine speeds (1800, 2100 and 2400 rpm), three engine loads (25, 50 and 75 %), four biodiesel/diesel blend (B0, B5, B10 and B15) and four EGR rates (0, 10, 20 and 30 %) have been applied to the engine. The considered emissions of the engine, measured at exhaust, were , CO, CO2, HC and smoke. The considered performance parameters were engine power, exhaust gas temperature and brake specific fuel consumption. The results of the study show that the addition of the biodiesel to the diesel fuel increases emission of the engine. The highest... |
