Latest Patents

Saiki’s listed patents address methods for identifying engine misfires under different operating conditions.

“Misfire detecting device for engine” describes a system that monitors engine angular-speed variation and can switch from all-cylinder operation to reduced-cylinder operation. If the system detects a possible misfire during reduced-cylinder operation, it increases the number of operating cylinders. If the possible misfire continues, the system identifies an engine misfire. The invention also includes a centrifugal damping part to reduce engine-caused vibration.

“Misfire detecting system for engine” describes a vehicle system that determines whether a misfire has occurred by assessing crank-angle fluctuation against a reference value. It also uses information related to intake-air density to adjust that reference value.

Career Highlights

Saiki’s listed inventions concern engine monitoring and control, particularly the detection of misfires while accounting for operating mode and intake-air conditions. His work is associated with Mazda Motor Corporation.

Collaborations

Saiki’s listed coworkers include Kenichi Ogasawara and Hiroshi Okubo.

Conclusion

Akio Saiki’s patent contributions focus on practical engine misfire detection, combining engine-operation controls and sensor-based measurements to support reliable diagnosis.
