Description of the Invention (1) [Technical Field to which the Invention belongs] The present invention relates to a fuel injection control device for a single-cylinder engine, and particularly relates to a four-cycle single-cylinder engine. Fuel injection control device for a single-cylinder engine with improved startability. [Know-how] A fuel injection control method for improving the startability of a four-cycle multi-cylinder engine, for example, a four-cycle four-cylinder engine has been proposed in the past, such as Japanese Patent Publication No. 63-14174. A 4-cycle 4-cylinder engine is used as a rotation detector of the engine. Generally, a crank angle detector showing a specific crank angle during 2 rotations (crank angle 720 °) of the crank shaft, and output fuel injection start timing Timing detector. According to the fuel injection control method of the aforementioned publication, as shown in FIG. 9, only at the first fuel injection timing (time t 1) immediately after the engine is started (time t 0), from # 1 to 4 (Ν ο · 1 ~ 4) All the injectors inject the required and sufficient amount of fuel to each cylinder, that is, simultaneous injection, and then after the crank shaft 2 rotates, that is, after each cylinder completes one ignition burst stroke (time t 2) to move to the normal fuel injection sequence. According to this method, the fuel injection is performed even if the timing of the injector immediately after the start cannot be specified, and the startability is improved. In recent years, fuel injection has been increasingly required in locomotives, and multi-cylinder engine vehicles have begun to be adopted. On the one hand, single-cylinder engines are often used in practical locomotives with small displacements. In this single-cylinder engine, many paper sizes are applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm)- ---------- Clothing ------- Order --------- Line (Please read the precautions on the back before filling in this page) -4- 487780 Ministry of Economy Wisdom A7 printed by the Consumer Cooperative of the Property Bureau _; __ B7_ V. Description of the invention (2.) Those who are using 4 cycle engines. Therefore, fuel injection may be used in the four-cycle single-cylinder engine in the future. However, when the aforementioned start-time control is applied to the four-cycle single-cylinder engine, there are the following problems. [Problems to be Solved by the Invention] (1) In a multi-cylinder engine such as a 4-cylinder engine, there is a cylinder B that is offset by 1 rotation (360 °) from a certain cylinder A. Therefore, especially in the initial stage of rocking (the initial stage of the rising edge of the control system), the control stage that divides the crankshaft 1 rotation at pulsation intervals should be allocated to the cylinder A, even if the crankshaft 1 rotation is actually staggered (3 6 0 ° ), By injecting fuel into cylinder A and cylinder B in the same manner, it is possible to complete the explosion on the side of cylinder B, and as a result, the startability will not be reduced. In addition, within a few rotations after the start of the explosion, cylinder A and cylinder B will be able to be identified by the crank angle sensor output. Therefore, at this time, there is no need to shift the crank rotation angle and stagger the distribution of the stages. The stage is not from cylinder A, but from cylinder B. However, in a single-cylinder engine, of course, because cylinder B does not exist, if the control stage is staggered by 1 rotation (360 °) from the actual crank shaft rotation angle, it will be difficult to continue the explosion in a stable manner. As a result, the startability of this multi-cylinder engine is poor. In addition, when the allocation of the detected levels is staggered, it is necessary to quickly correct all the levels previously allocated. (2) Although a single-cylinder engine is important because of its low cost due to its structure, the same crank angle detector and timing detector as the multi-cylinder engine are provided with the fuel injection system.

Description of the invention (3) The cost increase rate is relatively large for single-cylinder engines, and it will damage the original advantages of single-cylinder engines problem. (Please read the notes on the back before filling this page) The purpose of the present invention is to provide a single-cylinder engine that has a better startability and can be realized at a low cost in view of the previous technology. Fuel injection control device. [Methods for solving problems] Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs In order to achieve the aforementioned purpose, the present invention is a fuel injection control device for a single-cylinder engine, which is provided between the rotation of the crank shaft 1 of the engine to generate The majority of the crank angle pulsations at equal intervals and the crank angle pulsations at unequal intervals. The motion generating device, and the pulsation signal generated from the start of the pulsation according to the aforementioned pulsation generating device, are assigned as a temporary level of injection control for each pulsation interval, And the internal pressure of the intake pipe of the engine is measured in accordance with the above-mentioned injection control temporary stage, and the internal pressure of the intake pipe is measured most often during the two rotations of the crank shaft, and the internal pressure of the intake pipe is measured according to the multiple times Alas, the injection control official stage which is shifted from the foregoing injection control temporary stage is characterized in that the initial injection is performed by the number of pulsations occurring within the rotation of the crank shaft 1 according to the pulsation signal from the start of the aforementioned swing, and In accordance with the aforementioned injection control temporary stage and injection control official stage, the second injection and ignition are performed. According to the present invention, the crankshaft 3 can be rotated and moved to the normal control, which can provide a better startability of the cylinder than that of the multi-cylinder engine. In addition, since the cam pulsator included in the multi-cylinder engine is not required, it can be constructed inexpensively.

Description of Invention (6) Jetting. Moreover, the initial injection is not limited to η = 3, and it only needs to be (the number of pulsations for the first injection) $ the number of pulsations for the rotation) / 2. Because the timing of the initial injection is too late, when the engine stops in the middle of the exhaust stroke, the crankshaft rotates within 180 ° of the crankshaft from the start to enter the intake stroke, and the mixture cannot be drawn into the combustion chamber, which reduces the start. The reason for the improvement effect. In addition, the injection width, that is, the injection amount, of the initial injection may be determined depending on the temperature of the engine. Moreover, as shown in Fig. 4, when viewed from the direction of rotation, the pulsations just before the missing pulsations (M e 1, M e 1 0, etc.) 'correspond to the dead points above the piston (Dc). When the judgment of step S3 becomes affirmative, that is, when the missing gear 1 rotates, the ECU3 will perform the processing of step S4 and detect the missing position (two N). The detection is based on Me (n)-Me (n + 1) > {Me (n ^ 1) -Me (n + 2)} x S (here, any of 1 < S < 4 (Number) holds, Me (n) is determined as the missing position N. In addition, although it is known from this process that the top dead center (TDC) of the piston is in the range of Me (η-1), it is unknown whether the top dead center is in the compression stroke or the exhaust stroke. It is detected and the following processing is performed. In step S5, the ECU 3 uses the aforementioned missing position (= N) to determine the temporary level N 0 · (= m). The temporary level No. (= m) will be determined by m = (15-N). In the case of FIG. 4, since η = 2, ^ 1 = 13. Next, the determination of steps S 6 to S 1 1 will be performed. That is, it will be judged whether the temporary NO.m is 3, 4, 10, 12, 13 This paper size applies the Chinese National Standard (CNS) A4 specification (210x 297 mm) -------- ------------- Order --------- Line * (Please read the precautions on the back before filling out this page) Printed by the Consumer Consumption Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 ___ 5. One of the invention description (7) and 18. This is because when the temporary level NO · m becomes the above-mentioned number, it has been determined in advance that the processes described below will be performed. Here, when referring to FIG. 4, the judgment that the temporary level NO · m at the time of startup is 1 3 'will be affirmative in step S 1 〇, and the process proceeds to step S 1 2' to determine whether it is read into the suction tube. Press pb 1 and Pb 2. If the determination is negative, the process proceeds to step S 1 3 and fuel is injected in an amount determined in accordance with the throttle opening degree and the engine rotation number N e. In this system, it is determined in advance that fuel injection will be performed at the temporary level N 0 · m = 1 3. Thereafter, it proceeds to step S 1 1. In step S 1 1, it is determined whether the temporary level No.m = 11.8 is satisfied. If the judgment becomes negative, the process proceeds to step S 1 5, the temporary level No.m is increased by 1, and the process returns to FIG. 2. Step S 6. The processes of steps S 6 to S 1 1 and S 1 5 are repeatedly performed, and the temporary levels N 0 · m are each increased by 1 to become temporary levels N 0 · m = 1 8. When the judgment of step S 1 1 becomes affirmative , The process proceeds to step s 1 6, the temporary level NO · ηm is reset to 0, the process proceeds to step S17, and the first suction tube internal pressure Pbl is read. It should be noted that the minimum value of the internal pressure Pb of the suction tube is held until the reading is completed. The timing at which 値 of the suction pipe internal pressure P b becomes the minimum ， obviously corresponds to the suction stroke of the engine. Next, proceeding to step s 1 5, the temporary level NO · m is increased by one. Furthermore, the processing of steps S6 to S 1 1 and S 1 5 described above is repeated. The judgment of step S 6 becomes affirmative (m = 3), and it will proceed to step S 1 8 'issue the ignition plug 5 for the first time. Ignition command. At this point, the fuel tank has been supplied with full fuel and will be completely detonated.

Description of Invention (8.) When affirmative (m = 4), the judgment of step S 1 9 is performed. That is, it will be judged whether or not P b 1 and p b 2 of the suction tube internal pressure P b have been read. At present, Pb 2 'is not read, so it will be a negative judgment. Next, if the determination of step S 8 is affirmative (m = 1 10), the process proceeds to step S20, and the second suction tube internal pressure Pb2 is read. Next, when the determination of step S 9 becomes affirmative (m = 1 2), the process proceeds to step s 2 1 and the second ignition is instructed. At this time, it is actually an exhaust stroke, and no fuel is supplied in the combustion chamber, so no fuel explosion will occur. Next, when the determination in step S 1 0 becomes affirmative (m = 1 3), the process proceeds to step S 1 2 and it is determined whether the first and second suction tube internal pressures P b 1 and Pb 2 have been read. When the determination is affirmative, the process proceeds to step S 2 2 to determine whether P b 1 > P b 2 is true. In this specific example, the judgment will be negative, so it will proceed to step S 2 3, and the temporary level X0 · m = 1 13 is confirmed as the formal level No. 13. As a result of this processing, the dead point (T D C) above the temporary level of Nom · m = 1 3 is the dead point above the exhaust stroke. In step S25, immediately after the formal level No. 13 is determined, fuel injection will be performed in accordance with the number of engine rotations Ne and other parameters. In addition, after step S25, the process proceeds to step S26, where a formal level process is performed, and fuel injection is performed at the injection time and amount read from the MP according to the level calculation. This fuel injection is performed approximately between steps No. 4 to 11. Small-displacement locomotive engines will be used at high rotation speeds and require injection from an early stage. And, it will be ignited at the ignition timing read from M A P according to the stage operation. The ignition will approximately apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) at this paper size. ------------------- Order ----- ---- Line ^^ (Please read the notes on the back before filling out this page) -11-487780 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of Invention (9) No. 1 ~ 3 of Time was carried out. As described above, in the specific example in FIG. 4, starting from the engine, when the crankshaft 2 rotates (720 °), the fuel will be completely detonated, and normal operation will be started. Therefore, it can provide the start of the Bimeiduo cylinder engine. Sex. Next, the operation starting from the top dead center of the exhaust or suction stroke will be described with reference to Figs. This specific example corresponds to a case where the phase difference is 360 ° from the fourth case. The operations up to steps S 1 to S 5 in FIG. 2 are the same as those in FIG. 4, and the temporary level NO. M becomes 13 in step S 5 is also the same as that in FIG. 4. Since the temporary level No.m is 1 3, first, the determination of step S 1 0 will become affirmative, and the process proceeds to step S 1 2, the determination becomes negative, and the fuel injection of step S 1 3 is performed. At this time, because the engine is at the top dead center (T D C) of the compression stroke, fuel will not be supplied into the combustion chamber. Next, the determination of step S 1 1 becomes affirmative, and the processing of step S 1 7 will be performed, which will also be read into the first suction tube internal pressure P b 1. At this time, since 尙 has not passed through the inhalation stroke, the internal pressure of the suction pipe P b 1 is 値 which shows the degree of atmospheric pressure. Furthermore, although there is an intake stroke immediately after the engine is started, the number of revolutions of the engine does not increase at this time, so the internal pressure P b of the intake pipe does not decrease. Next, the determination in step S6 becomes affirmative, and ignition is performed in step S18. However, at this time, since the fuel is not supplied in the combustion chamber, the fuel will not burst by the aforementioned ignition. Next, when the judgment of step S7 becomes affirmative, the judgment of step S19 is performed, but since the internal pressure Pb 2 of the second suction pipe is not read, the judgment becomes negative.

Description of the invention (ι〇) When the judgment of step S 8 becomes affirmative, it will proceed to step S 2 0, and read the 2nd inspiratory tube pressure P b 2. Because the internal pressure P b of the suction tube during the inspiratory stroke, that is, the minimum 値 has been maintained, the second internal pressure P b 2 of the suction tube will become smaller than P b 1. When step S9 becomes affirmative, the process proceeds to step S21 and an ignition command is issued. At this time, because the fuel injected at the aforementioned time t 2 is in the intake stroke and is inhaled in the combustion chamber after the temporary stage No.m = 4, the fuel is completely detonated and the engine is started. That is, 'will be started normally. Next, when the determination in step S 1 0 is affirmative, the process proceeds to step S 1 2 and it is determined whether or not the second suction tube internal pressures P b 1 and Pb 2 have been read. When the determination is affirmative, the process proceeds to step S22, and it is determined whether P b 1 > P b 2 holds. In this specific example, since this judgment will be affirmative, the process will proceed to step S 2 4 and the temporary level No. m 2 13 will be determined as the formal level No. 4. In this case, it is determined from the judgment of step S 2 2 ′ that the top dead point (Dc) of the temporary level No.m = 1 3 is the dead point above the compression stroke. Thereafter, it will proceed to step S2, and the fuel will be injected at the injection time and amount read from M AP in accordance with the formal-level calculation as before.

Invention Description ( 11) At 3600, the fuel will be completely detonated and normal operation will be started. "Receiver" describes the operation of the missing portion 'piston stopped' in the middle of the expansion stroke with reference to Figs. 2, 3 and 6. Moreover, in locomotives, etc., although the piston will continue to move from inertia when the engine is stopped, the compression stroke of the crankshaft is the largest. It is likely that the piston will stop during the expansion stroke, and the start of the next engine will start from The expansion stroke starts halfway. Now, suppose that at time t 0 in FIG. 6, the engine starts to start, and the operations of steps S 1 to S 3 in FIG. 2 are performed in the same manner as described above. When the number of counted pulses η in step S 2 becomes 3, Proceeding to step S 1 4, the ECU 3 outputs a command to the injector 4 to inject a predetermined amount of fuel. As a result, a predetermined amount of fuel will be injected at time t 1. When the judgment of step S3 becomes affirmative and the process proceeds to step S4, the position where the missing position N is 9 is detected, and at step S5, the temporary level Nom · m is determined to be 6. Therefore, the temporary level will start from No. 6. As a result, first, if the determination in step S 8 is affirmative (m = 1 0), the process proceeds to step S 2 0 and the first suction tube internal pressure P b 1 is read. At this time, it will be read into the hold of the suction stroke, so it will become a small one. Next, when the determination of step S 9 is affirmative (m = 2 1 2), the process proceeds to step S 2 1 and an ignition command is issued. At this time, since the fuel injected at the aforementioned time t 1 is sucked into the combustion chamber in the subsequent intake stroke, the engine will be completely detonated and started. Next, when processing is performed and the temporary level No.m is increased by 1 to m = 1 3 and the determination of step S 1 0 is affirmative, the process proceeds to step S 1 2 'whether it is judged whether it has been read for the second time.

At present, since the second intake pipe internal pressure Pb 2 has not been read, the process proceeds to step S 1 3 and fuel injection is performed in an amount corresponding to the number of revolutions N e of the engine. When the temporary level No.m is incremented by 1, and the judgment of step S 1 1 becomes affirmative (m = 1 8), it proceeds to step S 1 6 to divide 淸 into 0, and at the same time proceeds to step S 17 and read the 2nd internal pressure of the inspiratory tube P b 2. Obviously, the second internal pressure of the suction tube P b 2 is larger than the first internal pressure of the suction tube P b 2 and is about the same as the atmospheric pressure. Next, when the determination of step S 6 is affirmative (m = 3), the process proceeds to step S 1 8 to be ignited. However, because of this, the fuel has not entered the combustion chamber and will not burst. When the determination in step S7 is affirmative (m = 4) ', the process proceeds to step S19, and it is determined whether or not the first and second intake pipe internal pressures Pb1 and Pb2 are read. This time, the determination becomes affirmative, and the process proceeds to step S27. In this step S27, it is judged whether P b 1 > P b 2 is true. In this specific example, since the judgment is negative, the process proceeds to step S 2 8. In step S 2 8, temporarily, level No.m = 4 is determined as the formal level No.13. In this system, the judgment of step S 2 7 has determined that the top dead point (TDC) of the temporary level No.m = 4 is the dead point above the exhaust stroke. When step S 2 7 is affirmative, the process proceeds to step S 29 and the temporary level NO.m = 4 is determined as the formal level No.4. After that, the process proceeds to the aforementioned step S26, and fuel is injected at the injection time and amount read from M AP in accordance with the normal-stage calculation as described above. Approximately, it is performed between stages No. 4 to 11.

Description of Invention (13) Use engine ' Will be used at high spins, so spray from early. And, it will be ignited at the ignition timing read from M A P according to the official calculation. Approximately 'will be performed between stages No. 1 ~ 3. According to this specific example ', as in the first specific example, when the crankshaft 2 is rotated (720 °) when the engine is started, the fuel is completely detonated and normal operation can be started. Furthermore, although in the foregoing description, when the missing gear 1 rotates the crank shaft 1 ', 9 pulses including missing pulses will be output, but the present invention is not limited to this, and may be more or less than nine. [Effects of the Invention] As described above, according to the present invention, the crank shaft 3 can be completely exploded at least once between the rotations of the crank shaft 3, and the crank shaft 3 can be rotated to move to the normal control. Therefore, it will be able to provide a better startability of the Biedor cylinder engine. In addition, since the cam pulsator included in the multi-cylinder engine is not required, it can be constructed inexpensively. In addition, since each pulsation of the crankshaft will generate a large number of pulsations, the smaller the number of cylinders, the larger the song will become ------------ · ----- --Order --------- Line · (Please read the precautions on the back before filling this page) Printed shaft C + T print control by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs厶 ΠΕ ΠΙΠΠ Mingfa's version of this book shows that the 1st explanation is the 3rd table of the single picture and the simple picture.
