Modern engines depend directly on the effectiveness of lubricating systems in terms of reliability and efficiency. An engine lubrication system does have the functions of reducing the friction between the bearing surfaces of moving parts and of heated emission and cleaning up the engine parts with the elimination of carbon and other foreign matter in order to be effectively operational. The lubrication system for these functions is the forced lubrication system in nearly all modern internal combustion engines. Although lubrication systems for internal combustion engines are subject to many variations, their components and operational methods are virtually identical. The lubrication industry strives to create environmentally friendly lubrication options for internal combustion engines, given the continuous environmental legislation. To tackle this challenge, lubricants that comply with environmental standards while maintaining high lubrication performance are required. This paper reviewed the performance of various types of engine oils after different types of modification applied, showing that a great many available references demonstrate that lubricant technologies have a strong potential to develop modern engines. The techniques for the nanofluid stability parameters were reviewed to perform a better comparison to the unmodified engine oils. In conclusion, current researches on engine oil efficiency still have some problems and challenges to take into account in terms of mechanisms to improve heat transfer, the practical use of engine oil for vehicles and further progress
This review evaluates on the concept and essential of bio composite and the synthetic composite fabric positioned over the years from the previous studies. The sorts and features of matrix and fiber filler reinforcement materials in composites also are discussed. The main findings in this review show that the center of composite relies on the natural fiber against synthetic and the roles of interplay lamination. Therefore, the contemporary hybrid compound for synthetic fiber and bio composite fiber in a composite shape is anticipated performing higher in the issue of mechanical energy in particular within the application of high impact, besides decreased dependency on artificial fiber. The table and figure previous results are comparing the experimental parameters available inside the literature review. This paper goes over the present advancement structure and development procedures included and related works on upgrading low and high impact energy captivation and upgrading the mechanical tenacity for high impact resistance applications
In recent years, the natural fibre such as kenaf fibre have been studied extensively. In this study, an experimental investigation was conducted to explore the effect of stitching technique of plain woven kenaf fabric on 3D hemisphere pressure clamped test. There were eight types of stitching patterns applied to the kenaf fabric. These patterns were divided into two categories that were single and double stitch patterns. Single stitching includes Vertical, Horizontal, Tilt 30° and Tilt 60°. Double stitching includes Box, Tilt 45°/90°, Tilt 30°/30° and Tilt 60°/60°. The radius of the hemispheric punch was 40 mm and the compression hemisphere displacement was fixed to the woven kenaf fabric by 40 mm. The clamps were placed on the plane plate, where the pressure was transformed from the hemisphere punch to the specified position on the stitching fabric with two supporting clamping tools. Box stitched pattern was found to indicate the highest compressive load of about 1.43 kN compared to other stitching patterns. Double stitching has a significant effect on 3D hemisphere pressure clamped test performance which enables an average improvement of 50 percent above the unstitched sample. This is due to the double cross stitch of the design of the box, the stress is distributed equally at 90° and 0°In recent years, the natural fibre such as kenaf fibre have been studied extensively.

There are a wide variety of software packages for designing and sizing of solar PV system. However, all of them are at the commercialized level which is more sophisticated and costly. This paper presents a simplified designing tool for array configuration of the grid-connected solar photovoltaic (GCPV) system. A simple, free and user-friendly tool known as PV.xls was developed to determine the array configuration of a GCPV system which can be applied for green housing. This tool was created for educational purposes to assist those with a limited technical background to design and size the system. The tool uses a basic simple Microsoft Excel spreadsheet. Database of PV modules, inverters, and simplified sizing procedure for the calculation of array configuration is embedded in the spreadsheet. The calculation is based on Malaysia Standard MS1837:2010
This research is aimed at mapping the subsurface structures such as fracture, weathered basement and fresh basement for groundwater investigation at Oke-Odo, Iwo, Osun State, Nigeria using combined geoelectric and statistical approach. Six (6) vertical electrical resistivity sounding data are collected based on schlumberger electrode arrangement configuration and maximum current electrode spacing of AB/2 along 100m within the study area. The vertical electrical sounding (VES) results presented as resist graph revealed the range of values for all the VES stations respectively. The depth ranges from (0.9–37.5 m), thickness ranges from (0.9 – 35.1 m) and resistivity ranges from (27.3 – 3353.4 ohms). These results were later used to generate 2-D geoelectrical maps of the subsurface study area, which revealed that the fractured-weathered basement varied, leading to diversity in groundwater prospects. A descriptive statistic was computed for resistivity, thickness and depths values respectively from the resist graph. The normality of the data was examined using the Shapiro- Wilk’s test while test of homogeneity of variance was carried out using the Levene’s test. Resistivity between layers were compared using the ANOVA followed by Duncan’s test for Post Hoc comparison while thickness and depth between layers were compared using the independent t-test. The modeled geoelectric and statistical approach on the groundwater potential revealed that groundwater yield was recorded in areas with large concentrations of fracture and weathering with the bedrock
