| A motorized thresher and a treadle cowpea thresher were evaluated in terms of threshing efficiency (%), throughput capacity (kg h-1), cleaning efficiency (%), mechanical damage (%) and percentage loss (%) for three commonly grown cowpea varieties in Nigeria. The three varieties were 994, IAR48 and TVX. The cylinder concave clearances were fixed at 13, 12 and 11 mm based on the major diameter of each cowpea variety. The investigation was conducted at three levels of moisture contents (12.5%, 15% and 17% wet basis). Evaluation results indicated that for motorized thresher threshing efficiency varied from 71.4 to 82.86%, 73.56 to 87.14% and 77. 63 to 88.57% while for treadle thresher threshing efficiency varied from 20.50 to 24.29%, 21.50 to 25.71% and... |

| The objective of this study was to investigate the effects of castor biodiesel and its blends on the emission characteristics of a compression ignition engine. The research work was carried out on a single cylinder, four-stroke, water cooled, direct injection diesel engine by using biodiesel made from castor oil, compared with conventional diesel. The fuels used in the analyses are B5, B10, B15, B20, B25, B50, B100 and convectional diesel. The compression ignition engine was operated by varying the loading conditions (0 – 6kW) in a step of 1kW. Based on the parameters measured, detailed analyses were carried out on five regulated exhaust emissions i.e. NOX, CO, CO2, O2, and HC. The results clearly indicated that the engine running with biodiesel and their... |
