Latest Patents

Kumagai's latest patents include an in-vehicle exhaust gas analysis system, an inspection system for this analysis system, an inspection method, and an inspection program. The in-vehicle exhaust gas analysis system features a flowmeter and an exhaust gas analyzer designed to analyze the concentration of specific components in exhaust gas. This system incorporates a standard gas supply mechanism that provides a standard gas containing a predetermined component to both the flowmeter and the exhaust gas analyzer. Additionally, it includes a detected mass calculation section that computes the detected mass of a predetermined component using the flow rate from the flowmeter and the concentration from the exhaust gas analyzer. A supply mass acquisition section is also present to obtain the supply mass of the predetermined component from the standard gas supply mechanism, while a mass comparison section compares the detected mass and the supply mass.

Another notable patent is the exhaust gas analyzer verification system. This system utilizes a reference gas supply part that can supply reference gas instead of exhaust gas, allowing for verification of the consistency between the supplied reference gas and the measured value from an analyzer. The system also features a control part that calculates the target supply amount of the reference gas based on setting flow rate and analysis range signals, ensuring accurate measurements.
