の過熱防止装置。[Scope of utility model registration request] Detects the vehicle's running speed and internal combustion engine rotation speed,
A driving state determination circuit outputs a signal when the vehicle is at a low vehicle speed below a predetermined speed and the internal combustion engine rotational speed reaches a high revolution of a predetermined number of times or more, and an output signal from the driving state determination circuit continues to be generated for a predetermined period of time. In the overheating prevention device for an internal combustion engine, the overheat prevention device includes a delay circuit that outputs a signal when the signal is output, and an internal combustion engine stop circuit that stops the internal combustion engine when the signal is output from the delay circuit, a first delay circuit that outputs a signal when a signal continues to occur for a predetermined period of time; a warning display circuit that displays a warning when a signal is output from the first delay circuit;
a second delay circuit that outputs a signal when the output signal of the delay circuit continues to occur for a second predetermined time; and an internal combustion engine stop that stops the internal combustion engine when the signal is output from the second delay circuit. 1. An overheat prevention device for an internal combustion engine, comprising a circuit and a switch means for turning on and off a signal input to the internal combustion engine stop circuit.
