Description

The fuel injection control device of motor and fuel injection control system
Technical field
The present invention relates to comprise the engine control that the fuel of motor sprays, particularly utilize the fuel injection control device and the fuel injection control system of motor of raising starting performance of the motor of external force startings such as thrust for there not being storage battery.
Background technique
Because developing by leaps and bounds of electron controls technology in recent years, for the motor of installing on the vehicle in recent years that comprises two-wheel vehicle etc. (internal-combustion engine), many having reached utilizes ECU (vehicle electronics control unit) to carry out central controlled degree.
ECU is according to the testing signal from the various sensors that are configured in motor each several part and periphery thereof, motor is carried out centralized control, so that for according to the operating condition that at every moment changes, bring into play the ability of motor to greatest extent, reduce fuel consumption simultaneously, reduce the harmful gas in the exhaust as far as possible, thereby carry out optiumum control.Thereby the fuel injection control of motor is one of most important control project of ECU.
For the motor of installing on the vehicles such as small-sized two-wheel car, the bicycle of being with prime mover, snowmoblie, small-sized motor boat, can not install and make actuating motor that engine start uses and in order to make the storage battery of actuating motor rotation usefulness, and start by the external force (manpower) of use starting lever or starting rope.
Be equipped with on the vehicle that utilizes the motor that such external force starts, installed to make and comprised the power supplier that ECU uses in interior control system work, though when engine revolution, accept power supply from the generator that is connected with the bent axle of motor, the needed supply voltage of supply control system, but in motor stops, because interruption of power supply from power supplier, so after the engine start, the control program of piloting engine reads in the needed engine control data of engine control.
Engine control procedures is stored in the common nonvolatile memories such as ROM as permanent memory, engine control owing to must proofread and correct or revise the learning control that changes the characteristic variations that causes according to the timeliness of motor, therefore must deposit rewritable storage in data.But storing such engine control must be non-volatile with memory of data, even make that motor stops, having cut off the power supply supply, and the storage data do not disappear yet.As such engine control data, the optimum igniting that comprise the data or the map figure that calculate suitable fuel injection amount and use, calculates spark plug is the data of usefulness constantly, as proofreading and correct or revise the principal element of these controls, can enumerate the principal element that causes air or flow fuel characteristic variations because adhere to sludge etc. in the sparger, gas stream measuring device, air-breathing path etc. with data.
According to the requirement of environment in recent years protection, these engine control use the memory space of data owing to complicated along with the optimization of engine control, thereby also constantly increase.
Therefore, utilize in installation in the vehicle of motor of external force such as thrust starting, utilize engine start and accept the EUC of power supply voltage supplying, after engine start, need long time with data in order to read in engine control from power suppling part.
Figure 7 shows that carried out in the past utilize the engine start of external force starting the time fuel spray sequential chart for example.
As shown in Figure 7, the supply voltage that rises if utilize engine start reaches specified value, and then reset signal is removed, and after each register in the ECU etc. carried out initialization process, the control program of piloting engine read the engine control data from nonvolatile memory.By like this, begin normal fuel injection control.Thereby, till beginning to so regular fuel injection control during from engine start, do not carry out fuel and spray according to the control of ECU.
For this reason, in the past for from engine start to carry out regular fuel till spraying during, in order to ensure or improve the starting performance of motor, carried out various trials.
Patent documentation 1 is as the technology relevant with fuel supply, disclosed a kind of fuel injection system, this device is such formation, it only is provided with the starting fuel supply device that uses and utilizes the negative pressure in air-breathing path and the engine start operation detection unit that moves when motor utilizes the external force starting when starting, when utilizing this engine start operation detection unit to detect engine start, by aforementioned starting fuel supply device fueling, simultaneously to air-breathing path ejection fuel.
In addition, patent documentation 2 has disclosed a kind of fuel injection system, this device reaches running (running that utilizes ECU to control) voluntarily before at motor, not according to the control of CPU (ECU), utilize other path that Fuelinjection nozzle is supplied with operating power, thereby open this Fuelinjection nozzle, a large amount of start-of-injection fuel.
Have, patent documentation 3 has disclosed a kind of fuel injection system again, and this device is when the thrust starting of carrying out motor repeatedly, in order to prevent that the mixture strength in the cylinder from raising, motor is difficult to the situation of starting gradually, and injecting times increases more, then shortens discharge time more.
Patent documentation 1: the spy opens clear 63-170528 communique
Patent documentation 2: the spy opens clear 63-259129 communique
Patent documentation 3: the spy opens flat 6-17682 communique
Yet, the fuel injection control of such motor, all the time be starting performance for the motor that improves starting such as the external force of utilizing thrust, during of short duration after motor utilizes external force starting, since be not according to the checkout value of various sensors and engine control with data carry out regular fuel injection control during, therefore the problem that produces is, motor reaches and surpasses the high rotating speed that needs, and perhaps comprises harmful gases such as many nitrogen oxide or carbon monoxide etc. owing to partial combustion in exhaust.
And, control comprises with data and has been calculated as the optimum igniting that carries out data or map figure that the needed fuel injection amount of regular fuel injection control uses, calculate spark plug data constantly, along with this control with the increase of data, need the regular hour to the time of carrying out till the regular fuel injection control during from this engine start.
Therefore, the objective of the invention is to, in the controlling method of the motor that utilizes external force startings such as thrust, by shorten as far as possible from engine start to utilize ECU carry out till the regular fuel injection control during, thereby try hard to improve the starting performance of motor, the fuel consumption increase of inhibition motor this period and harmful gas discharge etc.
