An Analysis of Diesel Fuel Spray Characteristics with Higher Injection Pressure
Higher injection pressure is one way to improve exhaust performance on diesel engines. The momentum transition of diesel fuel spray from the nozzle was measured, and the injection velocity was calculated. The injection velocity was also measured by observing spray penetration using a high-speed camera.

A study of exhaust performance improvement with higher injection pressure on diesel engine
Higher pressure injection on diesel engines contributes to increasing spray momentum and improving spray atomization. Higher momentum and fine atomization promote fuel-air mixing resulting in soot reduction. we measured exhaust gas characteristics by combustion tests using a single-cylinder engine. Actual measurement results show soot reduction with fuel injection pressure increasing.

Social Acceptance of Autonomous Driving Based on Safety Assurance
Social acceptance of autonomous driving is a challenging problem whereas the international rulemakings regarding a safety assurance of the autonomous vehicles (AVs) are undergoing. An issue of evaluating the social acceptance is how to make realistically imaginable survey when the new technology would change everyday life of users. Another issue is how to distinguish between “agree” and “agree in general but disagree in case of my risk,” known as a Not-In-My-Backyard (NIMBY) problem. To address these issues, this paper investigated the social acceptance of AVs by conducting user survey based on foreseen accidents of AVs from the safety assurance points of view.

Development of Damage Evaluation Procedure for Various Materials Using MSE Method
We examined the application of the MSE method to predict degree of damage in resin coatings for sliding bearings and metal bonded materials. As the result of trial, it was suggested that the MSE method could be applied to predict the aggregation of additives in resin coating and the damage of intermetallic components at the metal bonded surfaces.

Improved accuracy of theoretical prediction of drive shaft strength
To contribute to the miniaturization and weight reduction of parts, it is necessary to consider the strength to determine whether the plastic region has been reached. As a method to achieve this, we performed a strength analysis that reflects the hardness distribution that affects the plasticity obtained from the heat treatment analysis. We will introduce the results of the consistency check between the above analysis results and experiments.

A study on the effect of vertical asymmetric vibrations on ride comfort and physiological responses during automobile driving
In this study, the effect of vertical vibration during vehicle driving were investigated on occupant comfort and physiological responses (heart rate, breathing, muscle stiffness, etc.). In particular, this paper considered the correlation between vertically symmetrical and vertically asymmetrical vibrations when exposed to occupants in bench tests.

Noise analysis and improvement verification in seat ventilation
In future vehicle interior climate control, maximizing the use of seat ventilation is necessary. However, the demand for sound quality of operating noise, especially in BEVs (Battery Electric Vehicles), is becoming stricter. Therefore, to achieve more comfortable operating noise, we clarified the current situation and the ideal state, and conducted verification to achieve our target.

The Role of Explainability in Shape Generative Models for Aerodynamic Car Design
Deep generative models have demonstrated potential in accelerating aerodynamic design via reduced simulation cost during car development. However, their practical adoption is limited by a lack of interpretability; this challenge obscures decision-making process and complicates the model integration into development workflows. Here, we introduce a technique for visualizing the influence of geometric features on the latent space of shape generative models, offering a pathway towards more interpretable and actionable generative design tools.
