Latest Patents

One of his latest inventions is the NOx generation amount control device. This device includes a cumulative amount calculating part that calculates a cumulative NOx amount by adding together multiple NOx exhaust amounts for each prescribed time interval. It also features a specifying part that determines a target value of the cumulative NOx amount based on the movement distance of a moving body or the output value of an engine. Additionally, an estimating part predicts the NOx amount based on the engine's rotation speed and fuel injection amount. The device includes a judging part that assesses whether the sum of the predicted NOx amount and the cumulative NOx amount exceeds the target value, and a determining part that establishes a scheduled NOx exhaust amount by adjusting the opening degree of the EGR valve and turbocharger.

Another significant patent is the piston temperature state monitoring system for internal combustion engines, along with a corresponding monitoring method. This system effectively manages the history of piston temperature. It counts the number of times piston temperature suppression control is activated. If the ratio of the temperature difference to the margin width meets a predetermined threshold, a count output system generates a count signal.
