With the worsening energy crisis and environment pollution, a higher-efficiency internal combustion engine with lower emissions is crucial for engine manufacturers. Gas fuels like natural gas and hydrogen are currently ...

The aim of this study was to find the initial design value of turbine blade for electrical type turbocompound system generating 10 kW. Turbocompound is one of the waste heat recovery system applying to internal combustion ...

The FFV engine technology that uses ethanol is emerging as a new paradigm for an alternative energy powertrain. In this study, the combustion and performance characteristics of a 1.0 L TGDI-FFV engine were analyzed when ...

In cold start condition, the catalyst and engine control method of T-GDI engine vehicle have direct impact on NMOG(Non Methane Organic Gas) and NOx emission. Results of testing three types of catalysts with similar material ...

In this study, we investigated the effect of three-way catalyst(TWC) compositions on the conversion efficiency of exhaust emissions from a 1.4 L turbo compressed natural gas(CNG) engine for passenger cars. For this reason, ...

The configuration of intake port is a dominant of inlet air flow and mixture formation in an engine. In this study, as an available technology to optimum intake port, the flow box system using resine has been applied. So ...

With the rapid development of RF based high speed wireless communication technology, devices that can be applied to IoT networks based on RF bandwidth are rapidly spreading, nevertheless, the development speed of the RF ...

CNG engine has been used as a transportation because of higher thermal efficiency and lower CO2 and particulate matter. However its out put power is decreased due to cylinder-to-cylinder variation during the supply of ...

The turbocharger, to decrease the harmful exhaust gas(CO, HC and etc.) and CO2 emission as well as the increase of the engine output, would be an useful method for engine downsizing. Therefore the thermal endurance of ...

This study was carried out to determine an optimal lean NOx trap (LNT) regeneration condition based on a NOx storage fraction. The LNT regeneration was performed by an in-cylinder post fuel injection method. A NOx storage ...
