Latest Patents

One of his latest patents is for a crawler construction machine. This machine features an engine and a fuel adjustment dial that adjusts the engine's speed according to the operation loads of the working equipment. The fuel adjustment dial is a rotary notchless dial that allows for continuous variable adjustment. The machine includes an adjustment position detector that detects the rotation adjustment position of the fuel adjustment dial. An engine controller, connected to the adjustment position detector, controls the engine's speed based on the adjustment position of the fuel adjustment dial. Additionally, a display device shows the percentage value of the adjustment position, with the maximum rotation position defined as 100%.

Another significant patent is for a work machine with an engine control device. This device ensures fine controllability and provides improved performance with a simple construction. The work machine includes an engine control device that manages the engine's output according to various operation modes. Operation mode selector switches allow the user to select from multiple operation modes. When a mode is selected that sets a relatively low revolution speed for the engine, the engine control device performs isochronous control to maintain a constant revolution speed, regardless of load fluctuations.
