Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Conspicuity issues on motorcycle at night time have always been a big concern as it is frequently observed motorcycle ridden without its light functioning and motorcyclist donning low conspicuous attire. This somehow has contributed to high percentage of motorcycle crashes at night time especially at junction road and rural area. This study aims to propose ways to improve the side conspicuity of motorcycles traveling on Malaysian roads at night through brighter appearance of motorcyclist and new intervention using retroreflective tapes on the side body of motorcycle. 38 drivers with average age of 34.8 years (SD=7.95) participated in a video experiment to detect a motorcycle presence on the road. Multiple motorcycle configurations with conspicuity measures of helmet color, attire color, presence of motorcycle light and retroreflective tapes were included in the experiment. The results indicate that a motorcycle without any conspicuity aid can be detected at average 33 meters from its side. The use of conspicuity aids of bright helmet, attire, presence of motorcycle light and retroreflective tapes have resulted in better motorcycle detection distance with the use of retroreflective tapes have helped motorcycle to detect furthest and quickest. Brighter motorcyclists’ and motorcycle’s appearances have improved motorcycle detectability at night time. Furthermore, the addition of retroreflective tapes on the side body of motorcycle have significantly improved motorcycle conspicuity and this suggested that the use of retroreflective tapes can help in reducing motorcycle conspicuity related crashes at junction road area at night time
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
