Latest Patents
One of his latest patents is the "Removal determination device for exhaust gas purification device." This innovative device accurately determines the removal of an exhaust gas purification device from an exhaust pipe. It includes an input temperature sensor that detects the temperature at the upstream side of the casing and an output temperature sensor that measures the temperature at the downstream side. Additionally, it features an engine stop time collector that measures the time period from the inactivation of the engine to its startup. The determiner assesses the presence of the exhaust gas purifying device based on the input and output temperatures, particularly when the time period meets a predetermined threshold.
Another notable patent is the "Abnormality diagnosis device for internal combustion engine." This device includes a setting unit connected to the intake passage, which defines a reference value for pressure in the gas flow passage. It also has an accumulating unit that integrates the difference between the reference value and the actual pressure when it falls below the reference value. The diagnosis unit then diagnoses any abnormalities in the passage based on the cumulative value. The setting unit adjusts the reference value based on the state of the internal combustion engine, ensuring accurate diagnosis.
