Carbon neutrality is becoming the latest global environmental paradigm, and biogas power generation aligns with this trend by converting methane gas into electrical energy. However, impurities in can corrode intercooler, thereby reducing efficiency. Consequently, it imperative to modify both material design of generator intercooler enhance corrosion resistance cooling This study employs Computational Fluid Dynamics (CFD) analyze thermal characteristics materials proposed changes. As a...
A diesel particulate filter (DPF) is an after-treatment device designed to capture and store exhaust matter emitted by vehicles. DPFs are damaged owing complex reasons, such as regeneration processes loads generated during driving. While can be damaged, they also manipulated, especially with hollow damage. In cases, the filtration performance deteriorates significantly, excessive amounts of smoke ash driving, resulting in environmental pollution. this study, DPF damage types were observed...
As environment problem became a worldwide issue, countries are tightening regulations regarding greenhouse gas reduction and improvement of air pollution problems. With these circumstances, one the renewable energies produced from biomass is getting attention. Bio-ethanol, which applicable to SI engine, showed positive effect on PFI (Port Fuel Injection) type. However, Ethanol has in homogeneous mixture formation because it high latent heat vaporization characteristics GDI (Gasoline Direct...
Emergency generators normally use diesel engines. The need to conduct weekly no-load operation inspections ensure stable performance in emergency situations. In particular, the with large engines mainly rectangle-type filter substrates. To minimize hazardous emissions generated by generators, optimizing reduction efficiency through computational fluid dynamics (CFD) analysis of flow characteristics particulate matter (PM)/NOX system is important. this study, we analyzed internal CFD, which...
The diesel particulate filter of a engine is an after-treatment device that removes matter from exhaust emissions by filtering and oxidating them through regeneration process. When the damaged, vehicle inspection usually performed; if cause not found using on-board diagnostics, then removed, visual test conducted. However, it easy to find exact being takes long time as substrate covered canister. In this study, computed radiography X-ray imaging technique, images were taken after placing...
Carbon neutrality is emerging as the latest global environmental paradigm, and biogas power generation fits this trend because it converts methane gas into electrical energy. However, impurities in corrode intercooler reduce efficiency. Therefore, necessary to change material design of generator improve its corrosion resistance cooling In study, thermal characteristics materials changes are analyzed using CFD. As a result, an optimal that maximizes efficiency while ensuring developed.
Aircraft reciprocating engines have been in operation over the past 100 years, which is a testament to their high levels of reliability and stability. Compared turbine engines, are at disadvantage when it comes high-speed flight. Nevertheless, they widely used mainly for small aircraft thanks specific power or power-to-weight ratio. Considering that propulsion systems account approximately 40% price, lightness performance key attributes achieve longer endurance. With advantages offered by...
