[ASSY Case] Engine Parts

[ASSY Case] Engine Parts

Assembly of components used in engine parts through in-house integrated production! We also accept OEM production.

We would like to introduce a case of assembly (ASSY) of materials used for engine parts through in-house integrated production. Breathers are components that have the function of pressure regulation between the internal pressure of the engine and the external atmospheric pressure. The pipes are secured against tube pull-out through bulge processing, and the connection between the pipes and the plates is guaranteed for airtightness through our unique press-fitting method, rather than brazing. Additionally, we also accept OEM production, so please feel free to make inquiries. 【Examples of Engine Parts Assembly】 ■ Control Panel ■ Decompressor ■ Governor-related ■ Rocker Arm, Flyweight, Decompressor *For more details, please refer to the PDF materials or feel free to contact us.

Circular economy of automobiles, construction machinery, and railway components.

Circular economy of automobiles, construction machinery, and railway components.

The circular economy involves the development of recycling technologies and channels.

Japan Engine is participating in Aichi Prefecture's "Circular Economy Promotion Plan (10-year plan starting from 2022)" and is working on the circular economy. Japan Engine is a rebuilt automotive engine company with 75 years of history. "Rebuilt" refers to the process of disassembling, processing, cleaning, replacing parts, assembling, and inspecting used machinery to restore it to like-new condition. In the circular economy, an important aspect alongside regeneration technology is the establishment of channels for resource circulation. The traditional recycling economy is an economic activity focused on "repairing and regenerating when broken," which has proven inefficient due to the inability to standardize regeneration processes, resulting in the prioritization of "mass production and mass disposal" as the "efficient" economic activity. By collaborating with manufacturers and large users, a more efficient resource regeneration system can be established, contributing to the circular economy's environmental goals. Our company has also obtained SBT certification and believes we can help reduce CO2 emissions across the entire supply chain (clarifying the amount of reduction). If you are considering the circular economy, please feel free to contact us.
