Research on direct carbon dioxide capture technology from motorcycle exhaust gas

Momona Hirao･TORU UENISHI (Kitami Institute of Technology)

The feasibility of capturing carbon dioxide directly from motorcycle exhaust gas was examined in this study. A device was built to capture carbon dioxide from the tailpipe of a motorcycle that uses a two-cylinder gasoline engine, and we evaluated its performance. By comparing the capture performance with that of a fixed-bed flow device that simulates the exhaust gas composition of a motorcycle, we were able to clarify the system development guidelines.

The feasibility of a system that captures carbon dioxide from motorcycles and converts it into fuel was examined in this study. A model was developed to capture carbon dioxide from a motorcycle's tailpipe and convert it into fuel, and we identified it using a fixed-bed flow reactor. Using the constructed model, we evaluated the performance and clarified the guidelines for system development.

CO₂ separation and capture from combustion engine exhaust gas using physical adsorption method
-Impact of engine types on CO₂ adsorption and desorption characteristics-

Tadanori Yanai (Shizuoka Institute of Science and Technology)

A CO₂ separation and capture system using a physical adsorption method with zeolite for internal combustion engines has been developed. In this study, impact of the difference between the two engine types (gasoline engine and diesel engine) on the CO₂ adsorption and desorption characteristics were investigated.

We have developed an after-treatment system for removing particle number (PN) and hydrocarbon (HC) using non-thermal plasma and HC adsorption .
Electrification of vehicle leads to lower exhaust gas temperature and constraint　on onboard space.
To overcome those matter, we have developed a compact and low temperature dependence system, and investigated the PN and HC removal performance under cold start condition.

Enhancement of reaction by molecular diffusion in Three-way Catalyst Porous Particles Membrane Filter

Mariko Watanabe (Sophia University)･Katsunori Hanamura (Japan Science and Technology Agency)

An effect of porous structure on enhancement of reaction was investigated by numerical simulation for a single agglomerated Three-way catalyst porous particle and its stacked porous particles as a thin membrane layer, including Knudsen diffusion in the element structure of a single porous particle.

Development of DPF Model Compatible with Whole Vehicle Model and Study on Regeneration Control (Second Report)

Kenta Hasegawa (Tokyo Denki University)･Norifumi Mizushima (AIST)･Taichi Kimura･Hiroyuki Yamada (Tokyo Denki University)

A diesel particulate filter (DPF) model that can be incorporated into a vehicle model developed with OpenModelica has been updated. In former model, exhaust gas temperature was estimated from table data, resulting serious discrepancy with experiments with transient condition such as a worldwide-harmonized light vehicles test cycle (WLTC).In this report, A simplified turbocharger and diesel oxidation catalyst (DOC) thermal model were developed and implemented to the vehicle model to more accurately predict the exhaust gas temperature behavior at the DPF inlet. By using the developed model, the effects of various DPF regeneration methods on post injected fuel consumption were investigated.
