Latest Patents

Hamaguchi's latest patents include a competence diagnosis system for a urea water temperature sensor designed to prevent misdiagnosis when urea water is replenished in a urea tank. This innovative system features a urea water level condition determination unit that stores the urea water level measured by a level sensor before key-off. It then compares this stored level with the current urea water level after key-on, allowing for accurate diagnosis through temperature comparison when the level difference is within a predetermined threshold value.

Another significant patent by Hamaguchi is a competence diagnosis system that limits diagnosis during a cold start. This system utilizes a cold start condition determination unit that measures various temperature differences immediately after engine starting. It ensures that diagnosis is only allowed when these temperature differences are within a predetermined threshold value, thereby improving the accuracy of the system during cold starts.
