In the past, the recovery of rice straw needs a lot of manpower. also need to be equipped with a vehicle, most of bundling machine were traction type bundling machine in domestic, secretary was inefficient, this greatly increases the cost of recycling, and the recovery of straw caused two compactions of soil, so that farmers will burn a lot of straw, cause pollution of the environment. Therefore, this study is based on the whole feeding rice combine harvester. added the straw bale device, One-time finished the rice harvesting, threshing cleaning and warehousing and Rice straw compression, bale and other processes. Improve the recovery efficiency of rice straw, reduce the cost of straw recovery, reduced the number of mechanicals going in the fields.

In particular, PM2.5 penetrates deep into the lungs, providing the cause of lung cancer. Recently, the Euro 6 regulation is proposed and regulated to reduce the emission source emitted from automobiles, but due to the increasing number of vehicles, it is only suggested as a temporary measure. Not only the pollution sources emitted from automobiles, but also the increase of fine dust emitted from thermal power generation or fine dust introduced from outside by wind is very serious. In addition, the generation of fine dust in narrow spaces, for example subways, has a serious effect on human activities. Although research and development is conducted to collect such fine dust, it is not easy technology in reality. Currently, the fine dust collection technology is collected through the filter, but the collection performance depends on the pore size of the filter. The smaller the pore size, the higher the collection performance, but seriously affects the engine performance because the back pressure increases. Therefore, it is important to optimize the pore size, structure or material of the filter to minimize the influence on the back pressure. In addition, if the back pressure increases due to the filter, the engine performance is deteriorated, and a regeneration device that removes the collected PM is required. Such a filter regeneration device is an essential device especially for automobile engines. This paper aims to develop a technology to apply metal diesel particulate filter to a heavy-duty diesel engine for commercial generators to secure the optimization technology for occurred back-pressure satisfying emissions (PM, CO, HC) environmental regulations for regeneration strategy of diesel particulate filter in near future.","PeriodicalId":287189,"journal":{"name":"International Journal of Computer-aided Mechanical Design and Implementation","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132507152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, as the consumption of lighting energy is second to only cooling and heating, a wide variety of research and technology development is being performed to resolve this problem. The light-shelf is a type of natural daylighting system that introduces outdoor natural light deep into the room, and various studies have been carried out in recognition of its efficiency. In particular, a previous study that combined a PV with a light-shelf was significant in terms of producing energy through the light-shelf. However, the previous study introduced the case in which the integrated PV and light-shelves attached the PV to the reflector of the light-shelf. In this way, the light-shelf and the PV operated at the same angle, which resulted in low daylighting and concentration efficiency. Therefore, the purpose of this study is to propose a movable light-shelf system with a built-in PV which operates at independent angles. The conclusions are as follows. The light-shelf system with a built-in PV proposed in this study consists of a structure where the light-shelf is installed at the bottom with the PV on top. In particular, the upper section has a hole to allow natural light to flow into the light-shelf at the bottom for daylighting. In addition, we enhanced the effectiveness of this study by suggesting control measures to operate the light-shelf system with a built-in PV. However, this study has limitations as it did not evaluate the performance of the light-shelf system with a built-in PV. Therefore, additional studies need to be performed in the future to evaluate and verify the performance.","PeriodicalId":287189,"journal":{"name":"International Journal of Computer-aided Mechanical Design and Implementation","volume":"470 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114460913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
