Description
Technical field
The invention belongs to the controlling method of motorcycle fuel delivery, particularly a kind of motorcycle plateau self-adapting control method according to altitude and atmospheric pressure control engine oil amount.
Background technique
The oxygen supply amount of motorcycle engine is the major parameter index of control engine oil igniting, and the oxygen supply amount of motorcycle engine is mainly from the ambient air of outside.As everyone knows, the oxygen-supplying amount in the atmosphere can reduce with the increase of altitude, and simultaneously, the atmospheric pressure of environment also can reduce with the increase of altitude.Oxygen-supplying amount in atmospheric pressure and the atmosphere becomes an inevitable proportional relation.According to the oxygen supply amount standard of plains region, the engine oil igniting for plateau section work will cause oil inflame insufficient because of the oxygen-supplying amount deficiency, the phenomenon of motorcycle over-emitting black exhaust; According to the oxygen supply amount standard of plateau section, be the engine oil igniting of plains region work, will reduce the service behaviour of motorcycle.
Now, the choke valve back at a lot of motorcycle engine suction port places all is equipped with pressure transducer and detects atmospheric pressure, as shown in Figure 1, the force value waveform of atmospheric pressure is the shape of similar sine wave herein, variation along with the engine load size, have the detected air pressure waveform of pressure transducer to change, as shown in Figure 2, the crest of waveform can be scabbled gradually, engine load is big more, the aperture of choke valve is just big more, and the distance of the section of scabbling is just long more, after choke valve is opened fully, waveform develops into the waveform of a line-like gradually, only remain with the part trough a little, the atmospheric pressure value that obtained this moment also is the most stable, and is opposite, if but engine load is less, the choke valve aperture is not enough, gathers the sinusoidal wave force value of being obtained and occurs deviation easily, and influence detects effect.
To this, a lot of manufacturers design the detecting method of multiple atmospheric pressure value, a kind of atmospheric pressure detector of internal-combustion engine is disclosed as the patent document of publication number CN1476515A, the speed probe that utilization is installed on motor, be used for four stroke two cycles (every the degree in crank angle of 30 degree) of motor are detected several suction pressure values P, two cycles obtains 24 pressure value P data altogether, compare wherein maximum value and minimum value again, and draw the difference DELTA of maximum value and minimum value, again predefined reference value among difference DELTA and the central electronic control unit ECU is compared, after crest is scabbled, the difference DELTA of maximum value and minimum value just can meet the detection requirement less than predefined reference value.
But the shortcoming of this detection mode is: A, the data volume of obtaining are more, and data operation quantity is bigger, takies the resource space of ECU, and a lot of computing is to flog a dead horse; B, when motorcycle is in high height above sea level, difference DELTA between air pressure maximum value and the minimum value can be less than normal, when being in low height above sea level, difference DELTA can be bigger than normal, and predefined reference value is an inflexible target among the ECU, can influence the testing precision of pressure value P.
Summary of the invention

The scope of described engine speed reference value B: less than 7000 rev/mins, if engine speed data, then satisfies second condition that atmospheric pressure is gathered less than engine speed reference value B.
Step 3 is obtained the atmospheric pressure value at engine intake place;
Setting pressure sensor behind the choke valve at motorcycle engine suction port place, obtain the pressure diagram of current location, after two conditions of described step 1 and step 2 satisfied simultaneously, ECU read currency P on the described pressure diagram at the specified position of engine operation cycle;
Step 4 is determined the motorcycle fuel delivery;
The prestore relation table of atmospheric pressure value P and motorcycle fuel delivery m of ECU inside according to current atmospheric pressure value P, is determined the fuel delivery that motorcycle is current.
The specified position of engine operation cycle is to run to preceding 10 °-50 ° of compression top center at motor.
The acquisition condition of the rotary speed data of the aperture data of choke valve and motor as atmospheric pressure value is set, and all carry engine load sensor 1 and speed probe 2 on the existing motorcycle, ECU has obtained these data automatically, and ECU has only carried out the comparison of throttle opening data and reference value A; The comparison of engine speed data and reference value B; And any some values in preceding 10 °-50 ° of compression top center just can obtain current atmospheric pressure value P, utilize former promising ECU that the pressure transducer of motorcycle load data is provided, and for ECU provides atmospheric pressure value P, have saved the resource space of ECU.
Remarkable result of the present invention is: with a pressure transducer, except that detection load, also cooperate a kind of motorcycle plateau self-adapting control method, comprehensive atmospheric pressure value, the aperture data of choke valve, engine speed data, the air pressure collection point at selection engine intake place, rationally avoid other disturbing factors, the detection of energy high height above sea level of self adaption and low height above sea level needs, and dynamically controls the motorcycle fuel delivery, guarantees testing precision, can also reduce the operand of ECU, save the resource space of ECU.
