estimated ROI · USD · AI analysis
ROI Calculation Logic

This technology could improve fuel efficiency by approximately 20% and reduce maintenance costs by 15% due to fewer parts compared to existing reciprocating engines. For example, for equipment with estimated annual fuel costs of ~$335K (AI est.) and maintenance costs of ~$65K (AI est.), the direct cost savings could be calculated as (~$335K 
× 0.2) + (~$65K × 0.15) = ~$67K + ~$10K = ~$77K per year (AI est.).

Speed to Market
3× faster than in-house development
This technology could shorten time-to-market by approximately 2.0 years compared to in-house R&D from scratch. The patent specification thoroughly details the mechanical control mechanism of the eccentric blade, the constraint by blades and grooves, and the design of each region in the combustion cycle. This significantly reduces the need for basic design verification and initial prototyping phases, enabling a smoother transition to the design and manufacturing process.
