Latest Patents

One of Tsuji's 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 significant patent is the "Internal combustion engine abnormality diagnosis device." This device is designed for internal combustion engines equipped with a supercharger. It includes a blow-by gas passage that connects a portion of the intake passage to the crankcase, along with a PCV pressure sensor that detects pressure in the blow-by gas passage. The device identifies specific periods of fluctuations in the intake air amount and calculates the fluctuations in PCV pressure to determine any abnormalities in the blow-by gas passage. Notably, the determination air amount is adjusted based on the crankshaft's rotational speed.
