Rapid Compression Expansion Machine (RCEM) <for research, universities, and student experiments>
Introducing a device that features a one-time combustion! It allows experiments to be conducted without being affected by residual gas!
The "Rapid Compression Expansion Machine (RCEM)" is a device designed for measuring and visualizing compression and expansion in engines. The engine is rotated by a motor, and compression and combustion can be performed once at any desired timing, allowing experiments to be conducted without the influence of residual gases. An encoder attached to the crankshaft captures the angle, enabling free setting of valve closing timing, fuel injection start timing, fuel injection duration, and ignition timing. 【Features】 ■ Engine Structure - Yanmar diesel engine L70V with the head removed - Extended piston and specially designed cylinder - Cylinder head is installed ■ The valve is dual-purpose for intake and exhaust, held open by a stopper ■ The extended piston has a φ58 quartz glass window for visualization ■ Images reflected by a mirror between the extended pistons can be captured using high-speed cameras, etc. *For more details, please refer to the PDF document or feel free to contact us.

Company information
FC Design is a company that independently develops, produces, and sells equipment related to engine control and development. In addition to products for motorcycles, eco-run products, and dynamometer products, we also develop custom equipment related to the development and measurement control of small engines. The company is originally composed of engineers who excel in engine design and development as well as electronic control design and development, aiming to discern the essence and eliminate waste in design. Our development and design policy has been cultivated through experiences in the eco-run team that has been active since before our establishment, and it has not changed from the custom equipment developed at the beginning to our current products. Manufacturing is not just about making things; it involves evaluating, improving, and achieving goals. We aim to actively develop and explore products to assist in educational and research settings, as well as individual creative activities. By shaping various ideas that arise in our daily work, from the requests of our customers to the experiences of each employee in manufacturing and education, we create new products. Enjoying the process of manufacturing ourselves and proposing the joy of development is the essence of FC Design's activities.
