Abstract

To prevent the amount of cooling water from reducing in a cooling water circulation between a radiator and a water jacket, and stabilize the temperature of the cooling water in a water-cooled engine with the water jacket for circulating the cooling water in a space toward the radiator in an engine body. A control unit 75 controls an engine control means 76 to reduce the output of the engine E responding to the detected temperature by a temperature detector 74, which detects a temperature representing the water temperature in the water jacket 62, reaching the set temperature set to a value corresponding to the boiling temperature of the cooling water in the water jacket.

Description of the invention (1) [Technical field to which the invention belongs] = Ming Shi is equipped with a water jacket for the engine host. T] When the water jacket circulates the cooling water between the radiator and the radiator , Can stabilize the temperature of the water. "History [Knowledgeable Technology] In the past, the water-cooled type double double 6462 No. 1 showed in the past, 1D Japanese Patent Unexamined Publication No. Hei 3 combined the test results to make the temperature of the cooling water of the electric fan rise . Force the fan to turn to prevent the temperature of the cooling water from increasing. [The problem to be solved by the invention] However, because the cooling water temperature in the cooling water circulation circuit calculated by the electric fan is above θ, the evaporation between the radiator and the water jacket runs out. If the amount is increased, scattered ::: too? The amount of cooling water from the radiator cover will be reduced, because the cooling water in the 7 suites is circulated back to the cooling water temperature according to the radiator; the known method is only difficult to correctly detect the cooling water reduction: if the fan is turned and controlled 'Second round = In this case, for. Cooling By reducing the amount of cooling water in the circuit, 75 provides a temperature stabilization device for water, which is more stable and stable than a fire-type engine. The purpose is to make the temperature of the cooling water tend to [the means to solve the problem], Κίΐΐΐ :: II.

The aforementioned temperature detector 74 is shown in Fig. 7, It is installed on the cylinder head 27a in the engine host 24 to directly detect the water temperature in the water jacket 62, and it can directly detect the water temperature in the bottom of the water jacket 62. Next, the function of this example will be explained, and the water jacket 62 Set the temperature ts to the value corresponding to the boiling temperature of the cooling water. If the detection temperature of the temperature detector 74 reaches this value, At a constant temperature, the control unit 75 lengthens the interval of the ignition timing to reduce the vehicle's walking speed. In this way, the ignition device 76 is controlled to reduce the output of the engine E. Therefore, the continuous boiling of the cooling water in the water jacket 62 can be prevented, and the cooling water can be suppressed. Evaporation from the radiator 5 8 'prevents the cooling water in the cooling water circulation circuit between the radiator 5 8 and the water jacket 6 2 from decreasing, thereby stabilizing the temperature of the engine E cold. The temperature detector 74 is installed in the engine host 24. The cylinder head 27a can directly detect the water temperature in the water jacket 62, so it can quickly detect the cooling water in the cooling water circulation circuit between the radiator 5 8 and the water jacket 62, and because

The cooling fan 59 is connected in a spiral manner, so that the heat dissipation capacity of the radiator 58 can be increased by connecting the heat through the shaft 25. Therefore, under normal conditions, the cold and long-lasting engine will not occur, and the cooling water circulation circuit ^ A II can be correctly detected to prevent the boiling of the cooling water in the water jacket 62; Xia reduces the amount of cooling water in the water circulation circuit, and ϋ 2 'prevents the stabilization of the cold temperature.

In addition to the control method of extending the output of E, it can also be used to reduce the engine's segmental complete burning, which is different from the front fire. With the step fork, "The King of the Woods fires, and the number of rotations of the engine is reduced to a set number of rotations of the device 52.
