Development of VOC Adsorption and Odor-Eliminating Filler Derived from Scraped Sea Urchin Shells

Mizuho Nishida･Shinnosuke Okada･Toyokazu Endo (Kasai Kogyo)

In coastlines worldwide, there's an abnormal proliferation of low-edible portions of sea urchins, leading to 'sea urchin barrens'. Some companies are attempting to capture and farm these sea urchins. However, the issue arises from the shells becoming waste after extracting the edible parts, leading to concerns about their disposal as industrial waste. This paper introduces the development of repurposing sea urchin shells as functional fillers.

An Analysis of Diesel RDE NOx Emission using Driver's Accelerator Pedal Index and Distribution

Yoon Woo Lee･Ki Hyung Joo･Jay Hwee Lee･Jong Ik Chun (Hyundai Motor)

In this study, we developed the driver's accelerator pedal index that can represent the driver's manipulation of the accelerator pedal, and analyzed the correlation between the index and RDE NOx EM. In addition, we analyzed the distribution of the index through big data of actual customers so that RDE development criteria can be set.

Consideration Regarding Drag Torque Reduction of Disc Brakes

Takashi Shimizu･Naoya Miyahara･Akinori Hirashima･Takumi Inoue (Advics)

One of the characteristics of disc brakes that contributes to fuel efficiency and electricity consumption is drag torque.
The purpose of this report is to reduce dynamic drag torque during city driving.
The factors and variations in drag torque under coast-down test were investigated.
A consideration is presented on a method for predicting drag torque and a method for designing to reduce it.

Holistic Brake Development Approach under the Impact of EU7

Christof Danner･Christian Wanek-Ruediger･Sampsa Martikainen (AVL List)

Non exhaust eissions are clearly one of the focal points for the upcoming Euro 7 legislation. In real life, the final emission factor as the ultimate result of a test in influenced by inaccuracies of numerous parts of the measurement system as well as additional influences of the unit under test. This study shows these influences of the systems inherent sources if imperfection on resukt quality based on theroretical relations, simulations, measurment results and experience gathered during productive brake emission testing. In addition this study will show influencing factors out of the brake developer view, how brake development can influence brake emission factors.
