Please tell us about your responsibilities and missions.

My mission is to reduce market failures of turbochargers. This is an important mission for safer and more comfortable use by the user, since turbocharger failures cause engine trouble. My main task for realizing this mission is to investigate the market defects. I collect and investigate turbochargers that have failed in the market and locate the cause of trouble. The results of the investigation are shared with the design, development, and manufacturing departments to support the planning of countermeasures. Moeover, we input information on past defects to newly developed products, aiming to realize design and manufacturing processes that are less prone to defects.

What do you like about IHI's Turbocharger and why?

What I like about turbochargers is that I can handle the product by myself and see every detail of it with my own eyes. Turbochargers range in size from those that can be held in one hand to those weighing about 30 kg, and even large ones can be moved by hand. Within this size range, turbochargers are composed of a variety of material parts, including ferrous, nonferrous, and plastic parts manufactured by various technologies, such as casting and cutting. Many of the machines manufactured by heavy industries are very large and not easy to move, but I can carry and disassemble turbochargers by myself. I feel that the turbocharger is an interesting product because I can touch it with my own hands, which is a product of the state-of-the-art technology.

Please tell us what is important to you in your work and your motto with reasons.

What is important to me in my work is to "correctly grasp the reality". In our work, we identify the causes of defects based on "information on phenomena occurring in the market" and "the condition of the returned turbochargers (survey results)". Therefore, if you guess information by yourself or make a judgment based on wrong investigation results, you will not be able to identify the true cause of defects. For that reason, I believe that it is essential to correctly grasp the reality in order to truly locate the defect factors. I strive to grasp the reality correctly by way of collecting missing information to my satisfaction, and sharing clear objectives of the investigation with those involved so as to obtain reliable investigation results.
