New description: [New technical field] This creation is about an engine idle speed automatic flameout device, especially a wide range of engine idling automatic flameout devices for carburetor type. [Prior Art] The exhaust gas emitted by the locomotive is the main factor causing air pollution and the greenhouse effect. The concentration of exhaust gas emitted by the locomotive during idle (such as the red light at the crossroads) is several times that of normal driving. To effectively prevent the locomotive from emitting exhaust gas at idle speed, the best way is to turn off the engine. In addition, due to the increasingly stringent requirements of environmental protection regulations, environmental protection related units in various countries have gradually required steam and locomotives to wait for traffic lights, traffic jams, and roadside suspensions, etc., that is, when the idle speed exceeds a certain period of time (such as 2 minutes), it must be mandatory. The engine is off. Therefore, how to control the engine to automatically extinguish the flame at idle speed, suppress the gas emissions of steam and locomotives, and reduce the consumption of gasoline fuel is indeed an issue that every vehicle manufacturer is eager to solve. Generally, the locomotive starting and extinguishing methods mostly use the key to turn the locomotive lock head. Please refer to Figure 1 for a schematic diagram of the circuit of the engine starting and extinguishing system. Generally speaking, when starting the carburetor type engine (not shown), riding The driver must first turn the locomotive lock with the right-hand key. First, the power switch 74 is activated to connect the battery 73, and then the brake switch 75 is activated by the left hand. At this time, the brake light 76 will be bright, that is, the brake circuit must be turned on before the engine can be started. In order to avoid the explosion, the right hand presses the start switch 77, through the start control switch 79, the start of the horse violation 78 and then through the capacitor discharge igniter (CDI: Capacitive Discharge 3 M443770

The rider needs to reverse the key to cut off the power. Because of &, for the locomotive rider, 5' in the engine is turned off and the money is turned on, and both hands must move back and forth between the handlebar and the lock of the locomotive. The operation is very complicated and inconvenient, which is not ideal. Yes, the locomotive that was only sold in recent years uses the electronic control unit (ECU) of the jet engine to detect whether the handle of the locomotive is not gripped according to the engine speed, speed and grip sensor. The message is to determine if the engine should be turned off. Referring to Fig. 2, there is shown another system architecture diagram of the engine speed-extinguishing system. The system architecture mainly includes a grip sensor 91, a vehicle speed sensor 92, a timer 93 and a control unit 94. The grip sensor 91 is used to measure whether the handle of the locomotive is gripped, the speed sensor 92 is used to measure the speed of the locomotive, and the timer 93 is used to measure the duration that the handle is not held, the control unit 94 is electrically connected to the gripper sensor 91, the vehicle speed sensor 92, and the timer 93. When the engine 95 of the locomotive is in the starting state, the gripper sensor 91 detects that the handle is not gripped, the timer 93 measures that the duration of the handle is not held reaches a predetermined value, and the vehicle speed sensor 92 measures the locomotive. When the vehicle speed is zero, that is, the locomotive system is in idle speed, the control unit 94 outputs a signal to control the locomotive engine 95 bonfire. Although this method can judge and help the rider to complete the automatic flameout action, it needs to install multiple sensors to measure a variety of different and necessary interpretations', so that the number of components increases, and the cost of the overall locomotive increases. It is very ideal, there is still room for improvement. M443770 The creator of this is because of this, in the spirit of active invention and creation, thinking about an engine that can solve the above problems, the idling automatic flameout device has been researched and completed to complete the creation. [New content] The main purpose of this creation is to provide an engine idle speed automatic flameout device, which can utilize the existing sensing components of the locomotive and the engine, and can automatically ignite the flame without adding a grip sensor or other additional sensing components. No, it only saves costs, and it also avoids the cumbersome inconvenience of operation. In order to achieve the above objectives, the engine of the present invention is set on a locomotive with a carburetor engine with a capacitor discharge igniter, including: a vehicle speed sensor, an engine speed sensor, and a timing. , an idle speed switch, an idle stop control switch and an idle stop control unit. The speed sensor is used to measure the speed of the locomotive. The engine speed sensor is used to measure the speed of the engine of the locomotive. During the duration of the test, the idle stop switch is used to select the control mode of the locomotive. • f idle automatic stop or no idle automatic stop state, while the idle stop control unit is electrically connected to the vehicle speed sensor, engine speed sensor, timer, and forbearance. Speed bonfire switch and idle bonfire control switch. Wherein, when the engine is in the starting state and the idle stop switch is in the idle automatic stop mode, and the vehicle speed measured by the vehicle speed sensor is zero and the duration of the timer measuring engine is less than the predetermined speed exceeds a predetermined time The idle speed control unit determines that the locomotive is at the stage 5 M443770 speed, and will output a signal to the idle stop control switch, and then control the capacitor discharge igniter to control the engine to stall. The predetermined time for the above locomotive idle speed can be set to 1 minute, 2 minutes, 3 minutes or other time 'visible local environmental protection regulations, and the predetermined time can be stored in the memory or other equivalent storage medium in the idle reduction control unit . The predetermined speed of the above engine can be set to 2 rpm, rpm, 1600 rpm or other number of revolutions, which can be set according to the performance of the engine, and the predetermined speed can be stored in the idle speed control. Memory in the unit or other equivalent storage medium. The above-mentioned idle stop switch can be a push switch or other equivalent component. The operation mode of the locomotive is the automatic speed stop or the automatic stop of the idle speed, that is, the rider can freely choose Do not automatically turn off the heart speed, just change it by pressing the switch. ▲ When the Outfield engine is in the starting state and the idle stop switch is in the operation mode of the automatic idle stop, the speed sensor will measure the speed of the vehicle and the speed of the measuring engine will be less than the pre-(four) speed. At the time, the 怠(4) fire control fresh element does not output any signal to control the flameout. That is, at this time, the rider sets the locomotive's operation mode to automatically ignite without idling. The relay type is a normally closed relay. The above idle speed control switch can be one or other equivalent components. Table: Speed M443770 The speed limit is automatically turned off, which can be displayed on the indicator light. This allows the rider to see it quickly and clearly. The locomotive may further include a starter motor, the starter motor is electrically connected to a start control switch, the idle stop control unit is electrically connected to the start control switch, and when the locomotive is to be started again in the idling stop, only the start switch may be pressed. There is no need to manually start the brake switch as in the prior art, because the brake circuit has been electrically connected to each other by the idle control unit and the start control switch of the starter motor. [Embodiment] Please refer to FIG. 3 and FIG. 4 , which are respectively a system architecture diagram and a circuit diagram of a preferred embodiment of the present invention. The engine idle speed automatic flameout system of the embodiment is set up to have a carburetor type. One of the engine 1 locomotive includes a vehicle speed sensor 21, an engine speed sensor 22, a timer 23, an idle stop switch 24, an idle stop control switch 26, a meter indicator 25, and a The capacitor discharge igniter 28 and an idle stop control unit _30. The 'speed sensor 21 is used to measure the speed of the locomotive, the engine speed sensor 22 is used to measure the speed of the engine 10, the timer 23 is used to measure the duration, and the idle stop switch 24 can provide the rider. The operation mode of the control locomotive is idling automatic igniting or automatic igniting, and the idling stop control unit 30 is electrically connected to the vehicle speed sensor 21, the engine speed sensor 22, the timer 23, and the idle idling switch 24 With the idle stop control ^ off 26. When the engine 10 is in the starting state and the idle stop switch 24 is in the stage, the 7 M443770 speed automatic extinguishing operation mode, the vehicle speed sensor 21 measures the vehicle speed to zero and the timer 23 measures the engine 1 speed to be less than the predetermined speed. When the predetermined time is exceeded, the idle reduction control unit 30 rotates a signal to the idle reduction control switch 26, thereby controlling the capacitive discharge igniter 28 to control the engine 10 to extinguish. In addition, when the engine 10 is in the starting state and the idle stop switch 24 is in the operating mode in which the idle speed is automatically turned off, the vehicle speed sensor 21 measures the vehicle speed to zero and the timer 23 measures the duration of the engine 1〇 is less than the predetermined speed. When the predetermined time is exceeded, the idle stop control unit 3 does not output any control of the engine 10, that is, the rider is set to operate. The operation mode of the fixed locomotive is automatic ignition without idling. In the example, the 'predetermined time is set to 2 minutes, and the engine 1〇 pre-twisted speed sighs to 2000 rpm (rpm) 'Idle speed bonfire switch 24 is a push switch, which is convenient for the locomotive rider to control the locomotive. The operation mode is automatic speed stop or automatic idle bonfire. The operation mode of the idle speed switch 24 is displayed on the indicator light 25 of the locomotive, so that the rider can quickly and clearly know the operation mode to decide whether to switch the change operation mode. As shown in FIG. 4, the step of starting the engine 1 is: the rider first activates the power switch 14 to connect the battery 13 ' and then manually activates the brake switch 15 , at which time the brake light 16 will be on, that is, the brake circuit must be turned on first. The engine 1 can be started to avoid the explosion, and the start switch 17 is pressed again. After the start control switch 19 is turned on, the starter motor 18 is turned on, and then the engine 10 can be started via the capacitor discharge igniter 28 and the ignition coil 12. M443770 In addition, when the locomotive is in idle speed, that is, the engine 1 〇 is in the starting state and the idling switch 24 is in the idling automatic flameout mode, the vehicle speed sensor 21 measures the vehicle speed to zero and the timer 23 measures the engine. When the rotation speed of less than 2000 rpm is more than 2 minutes, the idle reduction control unit 30 outputs a signal to the idle reduction control switch 26, and the idle reduction control switch 26 receives the signal outputted by the idle reduction control unit 3 Thereafter, the electric valley discharge igniter 28 can be controlled to control the engine 1 bonfire without the need for the rider to turn the power by hand to turn off the power as in the prior art. In the zero example of the present embodiment, the idle reduction control switch 26 is a normally closed relay. In addition, as shown in FIG. 4, in the present embodiment, since the idle stop control unit 30 and the start control switch 19 of the starter motor 18 are electrically connected, when the locomotive is in an idle stop command to be restarted, only the start switch needs to be pressed. 17 can be 'no need to pull the brake switch 15 as in the prior art, because the brake circuit has been electrically connected to each other by the idle stop control unit 30 and the start control switch 19. Therefore, the present embodiment can utilize the existing sensing components of the locomotive and the engine, and does not need to add a grip sensor or other additional sensing elements as in the conventional technology, and can automatically ignite the flame, which not only saves cost, but also It can avoid the cumbersome inconvenience of operation.
