In addition, various automatic chokes have been developed, by which the rotational speed of the engine is automatically increased when the yarn is cold-started. In the automatic resistance state, there is a hot wax type automatic flow blocker, which is closed by the bypass passage of the 19-throttle valve, for example (6), which can be: • At lower temperatures, the condensation condensation pulls the throttle valve (eg, valve) up to open the bypass passage. At higher temperatures, the wax expands: 阙 presses down to close the bypass passage. If the bypass channel is, the amount of intake air will increase, so the airborne fuel will control the injection of a large amount of dip, which increases the private life of her A person & ^ LiΛ..., I motive rotation speed . For the heating of the wax heater, when the heating is performed, the temperature of the wax is gradually increased at a lower temperature, and the new temperature is increased.

The heating characteristics of the different heater waxes by the reference A are approximately equal to a constant', so starting from the start of the engine to the above (4) The time required to close the bypass passage is near-heart-changing. However, when the temperature at which the engine is cold-started is different (e.g., depending on the weather is cold heat), the time required for heating also varies. There is a problem with the conventional automatic choke, that is, it is impossible to teach according to the temperature at the cold start of the engine. Also, the time required for heating varies with atmospheric pressure. For example, 'in the elevation zone where the atmospheric pressure is low' is less than the opening provided by the opening of the bypass passage of the same size, so the engine rotation speed is inevitably lowered, and it takes a longer time to heat. However, since in the conventional automatic choke, the time required before the bypass passage is closed as described above is constant, it is impossible to perform heating according to the atmosphere.

[Complex Mode] A first embodiment of the present invention is as follows. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing an overall structure of an engine for a motorcycle and a control device therefor. The engine 丨 is a relatively small displacement single-cylinder, four-stroke engine including a cylinder block 2, a crankshaft 3, a piston 4, a combustion chamber 5, an intake pipe 6, an intake valve 7, and a An exhaust pipe 8, an exhaust valve 9, a spark plug 1 and an ignition coil u. In the intake pipe 6, there is a throttle valve 12 which is adjusted to open/close according to the accelerator opening, and an injector 13 as a fuel injection device is sprayed on the intake pipe 6 from the downstream side of the flow valve 12 The gate 13 is connected to one of the fuel tanks 19, a fuel pump π, and a pressure control valve 16. A bypass passage 6a is provided in the region of the throttle valve 12 of the intake pipe 6, the bypass passage passing by the throttle valve 12, and an automatic choke 14 is provided in the bypass passage. The automatic choke 14 is of the hot wax type, wherein the bypass passage 6a is closed by the supply of the heater 23, as described above, when the engine 1 is cold-started, the condensation of the wax causes the valve (such as a The poppet valve is pulled up to open the Wan Wan channel, and when the temperature of the wax rises due to the energization of the heater 23, the expansion of the wax causes the valve to be pushed down to close the bypass passage. The heater 23 is of a so-called PTC (Positive Temperature Coefficient Thermistor) type, and its heating characteristics can be adjusted by controlling the pen value. 86605 1281530 The operating conditions of the engine 1 and the state of energy of the heater of the automatic choke 14 are controlled by an engine control unit 15, which has a processor (such as a microcomputer). As means for detecting the control input of the engine control unit 15 or the operating conditions of the engine, the apparatus provided includes a crank angle sensor 20 for detecting the angle or phase of rotation of the crankshaft 3; a cooling water temperature sensor 21 of the temperature of the cylinder block 2 or the temperature of the cooling water or the temperature of an engine body; a discharge air-fuel ratio sensor 22 for detecting the air-fuel ratio in the exhaust pipe 8; An intake pressure sensor 24 for detecting the intake pressure in the intake pipe 6, and an intake air temperature sensor for detecting the temperature or the intake air temperature in the intake pipe 6. The engine control unit 15 inputs signals detected by these sensors, and outputs control signals to the fuel pump 17, the pressure control valve 16, the injector 13, the ignition coil " and the heater 23. Now, a method of detecting the atmospheric pressure by the intake pressure detected by the intake pressure sensor 24 will be explained. For example, when the engine is operating at a relatively slow speed like idling, i.e., the engine load is very small, it is found that the intake pressure before the intake valve is about to open is approximately equal to atmospheric pressure. Therefore, in this embodiment, 'when the engine rotational speed is low, the intake valve is about to be opened (w, the atmospheric pressure can be measured by the intake pressure. When the engine operating condition is controlled by the engine control unit 15 It is also necessary to use: = air pressure 'in some cases, the atmospheric pressure detecting means is provided in the engine control unit 15 to _ atmospheric pressure, which may not be directly related to the present invention', so its detailed description is omitted. 86605 Next The process of energizing the heater performed in the engine control unit -10- 1281530 15 will be described using the flow chart of Fig. 2. The process of Fig. 2 is by _ timing every __ predetermined sampling time ΛΤ The interrupt processing (four) line, for example, ^ is set to about 1G milliseconds after the engine starts to rotate. Although the flow chart specifically transmits information steps, the information acquired by the processing is continuously updated and stored in the storage device, necessary At this time, information or a program required for the processing can be read from the storage clothing. In this processing, first, in step S1, the reading air pressure detecting means is measured by the air intake fool. The atmospheric pressure and the cooling water temperature measured by the cooling water temperature sensor or the engine temperature are used to set an energizing on = delay time D according to the control chart of Fig. 3. The horizontal axis of the control chart of Fig. 3 represents the engine temperature. , coveted two table energy supply start delay time 'atmospheric pressure as a parameter to the edge garment binding adjustment, so that at lower engine temperature and atmospheric pressure, the energy supply start delay time increases.

The setting of the 菘 energization start delay time D is such that the delay time D increases when the engine temperature and the atmosphere 昼 are low. As described above, when the engine starts to rotate, the heating time required for the lower engine temperature and the lower atmospheric pressure with respect to the intake air amount is longer. Because &, if the energization start delay time D can be set based on these parameters, it can be heated according to the engine temperature and atmospheric pressure. π, the book describes a second embodiment of the automatic flow blocking control device of the present invention. Although the general structure of the engine of this embodiment is the same as that of the embodiment, in this embodiment, the heating: the following is the occupancy ratio control 'in the engine control unit There is a 4 Wei (pulse width modulation) driving circuit in the 15th, which is adjusted so that the duty ratio control signal of the processor (such as a microcomputer) is converted into a pulse modulation driving signal of the controller 23. This duty ratio is the ratio of the operating state of the pulse signal, which is known to us. In the specific embodiment, the processing of the heating benefit supply control performed in the engine control unit 15 has been changed from the sound to the flow chart shown in Fig. 5. Figure 2, the second; in the heart time ΔΤ by the timer 疋 in the mother - the predetermined sampling is after the engine starts to rotate about i: milli, for example, 'ΔΤ set a special transfer information step, by the process ^ by L flow chart The information is not updated and stored, and the information is stored in the storage device 86605 ^ 仗 储存 储存 . . . . . 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 In this process, first, in step S11, the intake pressure detected by the air pressure detecting means is read to obtain atmospheric pressure, and the cooling water temperature or the engine temperature is measured by the cooling water temperature sensor for control according to FIG. The graph sets the duty cycle energy rate of the heating state 23, which is related to the elapsed time since the engine began to rotate. The control chart of Fig. 6 includes two graphs, one of which is a graph in which an achievable duty ratio D/T〇 is set to be associated with the measured atmospheric pressure atm, and the other graph is still in the graph. In the figure, a duty cycle rate is set to be related to elapsed time using the achievable duty ratio D/TG and engine temperature. The control map of Figure 6a is designed such that the achievable duty cycle can increase as the atmospheric pressure atm increases. The control diagram of Figure 6b is designed to saturate the duty cycle to the achievable duty cycle d/Tq as time elapses, while allowing the component duty rate to increase as the engine temperature increases. That is to say, the higher the engine temperature and the higher the atmospheric pressure, the higher the duty ratio energy. Then, the process proceeds to step S12, in which the energy supply state of the heater 23 is controlled by the duty ratio by the duty ratio energy set in the step su. Under the heater energization control, for example, if the achievable duty ratio D/T0 is 100%, that is, if the atmospheric pressure is high and the engine temperature is low, the drive signal to the heater 23 is reached after the engine starts to rotate. The rate of vacancy rate increases gradually, as shown in Figure 7a (the time axis is shortened). After a certain period of time, it reaches the king, "big evil. It is well known to us because the duty ratio control can control the current value, so - a larger duty cycle suppresses a larger current value for the heater, and a smaller duty cycle produces a smaller electrical charge 86605 - 13-1281530 for the heater 23. This indicates that the duty cycle allows control The heating characteristics and control 23 control the temperature of the achievable wax. For example, if the current engine temperature, the engine or idling speed is characterized by the virtual & τ force velocity time in Fig. 7b, ..., if the engine speed follows < π P When the engine is powered immediately after the start of rotation, the characteristic of the engine's rotational speed as a function of time is as shown in Fig. 7b"= When the power is supplied to the heater 23: the duty ratio or the duty ratio is reduced. &gt A ^ ^ A H Zhai 23 slows down the heating characteristics of the wax, and the sub-allowing of the automatic choke is slow,

At this time, the duty ratio set in the control chart of the private = = for the lower engine temperature and = 2 2:00 to make the engine rotation speed or idling speed drop the slope of the mouth, 'love, so the moon is enough to heat according to the engine temperature That is, when the temperature of the motive is low, the heating time can be increased. In the field, the other side, see the control chart of the figure & the lower the atmospheric pressure, the smaller the duty ratio. For example, as shown in Fig. 8 from Fig. 8a, the graph shows that the heater drive signal does not increase when the atmospheric pressure is low, even after the lapse of time. Yeah, the wax is controlled by the expansion state of the heater so that the bypass passage is kept slightly open, so it can be maintained - relative

For example, if the engine's desired rotational speed or idling speed is indicated by the dotted line in Figure 8b and the low-altitude high-altitude area, due to the aforementioned intake air volume, The problem is that even the same size of the bypass passage opening can not be provided - high engine rotation speed 86605 -14 1281530 J 丨 open the private 丨 丨 to the heater Μ when fully powered, if the engine rotation speed, that is, the engine The variation of the rotational speed with time is shown by the double dotted line in Fig. 8b. In this specific embodiment, as shown by the solid line in Fig. 8b, the duty ratio or work is reduced immediately after the heater is energized. The state ratio is used to reduce the engine rotation speed or the descending slope of the empty speed home, so that the achievable duty ratio is reduced to increase the achievable speed of the machine or the idling speed that can be achieved, so that the speed of the engine (4) can be changed with time. The desired idle speed characteristic. This makes it possible to heat up according to atmospheric pressure and to properly control the engine speed in the idling state. In the automatic choke control device already described, the delay start energy supply time method is adopted, and in the second L real = the control duty ratio is selected, but these functions can also be combined at the beginning, when When the engine temperature is low or the atmospheric pressure is low, the door, the initial energy supply time, and then the output – the engine control signal. brain. $ Various kinds of processors to replace the micro-electricity [The effect of the present invention] According to the patent application scope control device, when the engine wave is low in the automatic blocking oxygen of the present invention, The delay time for starting the energy supply. ^ 曰口士一一灭灭器开,. This is the case when the engine smuggler starts to turn to off - # & The bypass channel can be used to generate M, w, and tens of kilograms, and the time will increase, and the temperature of the engine will be heated. In addition, according to the application for the second section of the patent park 86605, each automatic blocking control -15-1281530 clothing, when the atmospheric pressure is low, the delay time can be increased. Therefore, the atmospheric pressure ^ heater starts to supply energy. When the vehicle is low, the engine starts to rotate from the engine to the atmospheric pressure for heating. Therefore, it can correspond to: the automatic resistance of the invention of the invention patent, when the engine temperature is low and the atmospheric pressure is low, the heating state starts to supply the delay time. Because of the 牟 ', too tempered to kill the soil and the low temperature of the motives and the lower cradle is lower, starting from the engine;:::r plus, one - should be launched in the second installment patent Fan Park item 4 In the automatic choke control of the present invention, when the temperature of the motive is low, the operating state ratio is reduced. Therefore, I:::::, the time required from the start of the engine rotation to the closing of the road will increase and heat. Therefore, 4 corresponds to the engine temperature to be strong: according to the invention, the automatic choke control of the invention according to the fifth aspect of the patent application: set, when the atmospheric pressure is low, the working state ratio is reduced. Therefore, when the pressure is low, the rotation from the engine to the closing_throttle bypass: = the time will increase, so it can be heated corresponding to the atmospheric pressure, and / / enough: after the heat 'in the idling state The engine rotational speed is appropriately controlled by controlling the throttle bypass and opening. Further, the step: the automatic choke "clothing" according to the invention of claim 6 is reduced when the engine temperature is low and the atmospheric pressure is low. Therefore, when the engine temperature is low and 86605 -16-128153 〇 from the start of the engine to the time required to close the bypass valve bypass passage, the force is increased, so it can be heated corresponding to the engine temperature and atmospheric pressure, and this is enough After heating, the engine rotational speed is appropriately controlled by controlling the opening of the throttle bypass passage in the to-rotation state.
