Fig. 2, Fig. 3 are the biopsy cavity marker devices plan view and the side view of expression embodiment of the invention suction unit.This example is for using the air-breathing structure example of being in charge of of 3 cylinder engines of the present invention, make be connected throttle valve body 2 outflow sides air-breathing be in charge of 4 and near the mounting point of injection valve 6, buckle, and branch becomes to the linearly extended radially air-breathing 4A of being in charge of of motor 5 each cylinder, 4B, 4C.Formation is arranged on three throttle orifices on the injection valve 6 towards the structure of motor 5 each cylinder suction mouth 5A, 5B, 5C.
Fig. 4, Fig. 5 are expression one embodiment of the invention Fuelinjection nozzle 6 nozzles figure nearby.The body of Fuelinjection nozzle 6 is the side importing type that fuel is imported from the body sidepiece.Enter the fuel of injection valve 6, be by by the movable valve 63 of electromagnetic force knee-action be arranged on 3 throttle orifices on the nozzle 64, and promptly the 1st cylinder measures with throttle orifice 63c with throttle orifice 65b, the 3rd cylinder with throttle orifice 65a, the 2nd cylinder and sprays.Make 3 throttle orifice 65a, 65b being arranged on the Fuelinjection nozzle 6,65c structure for making the fuel distributed uniform, making towards the intakeport of each cylinder of motor 5.
Fig. 6, Fig. 7 are the time diagram of explanation fuel injection timing.In example shown in Figure 6, an injection valve 4 is simultaneously to the three cylinder engine burner oil, and motor per two changes only injection once.As injection timing, the 2nd cylinder that is exactly position, centre placed in the middle in three cylinders when the position of suction stroke A, from 3 throttle orifice 65a, 65b, 65c simultaneously to each cylinder injection.Make in addition zone become the position of prohibition of fuel injection, make the fuel that sprays into air suction way from Fuelinjection nozzle, in air suction way one side with suck air mixing and simultaneously offer motor 5.At this moment, the spray flow of fuel is subjected to the influence of each cylinder because of inhaled air flow path directions such as suction strokes.According to the example of Fig. 6, fixing on the suction stroke of the 2nd cylinder that is positioned at middle position three cylinders to the timing of air suction way burner oil, distribute injection to each cylinder from the throttle orifice of a fuel valve from Fuelinjection nozzle 6.Make zone in addition become the prohibition of fuel injection position.In view of the above, the fuel that sprays in air suction way from a Fuelinjection nozzle 6 is always had towards being in suction stroke and being positioned at the directivity of the 2nd cylinder of central authorities, and the either side about not being partial to.Therefore, can make the spray direction of fuel directly keep stable, its result, the fuel partition characteristic of multi-cylinder engine improves.Because the difference of A/F does not exist between each cylinder, the service performance in the time of making the transition operation especially improves.
In the example of Fig. 7, the cylinder that is arranged in three cylinder two ends: promptly the suction stroke of arbitrary cylinder of the 1st, the 3rd cylinder is as the prohibition of fuel injection position, and make in addition regional A, B become the position that to carry out the fuel injection, an injection valve 4 is simultaneously to three cylinder engine burner oils, and motor per two changes only injection once.The partition characteristic of each cylinder fuel is improved.In this example, during low-speed running,, requiring to have the acceleration of good partition characteristic, when running up, also can be formed in regional A burner oil at regional A or B burner oil.
Fig. 8 is an another embodiment of the present invention, and to four-banger 5, sucking pipe 6 is divided into 4 sucking pipe 6A, 6B, 6C, 6D.Fuelinjection nozzle 6 is simultaneously and equably to these sucking pipe burner oils, only changes at motor per two and sprays once.
Fig. 9 is the time diagram of explanation four-banger fuel injection timing.For this four-banger, also be simultaneously to each cylinder injection fuel from an injection valve 4.As injection timing, spray when being the suction stroke A of the 2nd, the 3rd cylinder in the middle of being positioned in four cylinders.Zone in addition is the prohibition of fuel injection position.Like this, can make and spurt into fuel in the air suction way from a Fuelinjection nozzle 6 and always have towards being in suction stroke, and the directivity of the 2nd, the 3rd cylinder in the middle of being positioned at, and not be partial to arbitrary cylinder one side at two ends, the left and right sides.Therefore, can make the injection direction of fuel keep stable always, its result, because multi-cylinder fuel partition characteristic is improved, the difference of A/F does not exist between each cylinder, the service performance in the time of making transition operation especially improves.
In the example of Figure 10, and when three cylinders all are non-suction stroke (A, B, C, but D) make fuel injection position, zone in addition is as the prohibition of fuel injection position.In addition, concerning real engine, have the situation of the discharge time that can not guarantee during beyond the suction stroke of whole cylinders to fill part, thereby also can consider as shown in Figure 9, on being added to during this during a part of suction stroke, act as a fuel between injection period.For example, also can make when low-speed running the arbitrary area spray fuel in regional A and even D, and when requiring to have the acceleration of good partition characteristic or running up, at regional A burner oil shown in Figure 9, in this embodiment, the fuel partition characteristic of each cylinder also can improve.
In the example of Figure 11, injection timing is the suction stroke that is positioned at the 2nd cylinder in the middle of three cylinders position that benchmark moves some after again shown in Figure 11 (a) usually, and promptly the position A till comprising from later half exhaust stroke to later half suction stroke sprays.The later half suction stroke B of the 2nd cylinder is partly utilized as inserting broadening.For example, when high speed rotating or accelerated service,, can guarantee necessary fuel, not make required service performance impaired by additional insertion broadening (A+B).When high speed rotating, by increasing fuel feed, can not only guarantee service performance, can also reduce the generation that combustion temperature suppresses NOX.When accelerated service, shown in Figure 11 (b), change interlock by making with the unlatching of throttle valve, the fuel feed that increases sharply, thereby just can improve the accelerated service characteristic.In addition because by advanced injection, can be in cylinder fueling make and produce cylinder suction wall deposited fuel limitedly, thereby make the air fuel ratio suitable, (raising exhaust purification performance) is improved runnability.
In the example of Figure 12, as injection timing, the specified time limit behind the overlapping period of Aspirating valves that is positioned at the 2nd cylinder in the middle of three cylinders and outlet valve, the position A that promptly comprises till preceding half compression stroke carries out burner oil.In this way, can make whether correct exhaust gas purification characteristic and the runnability that determines is improved by air fuel ratio control.In addition, in the time of can also preventing that outlet valve from opening fuel to exhaust one side leak, because of the catalyzer burning forms non-normal temperature, and make the generation of catalyst damage situation.
Only can provide with an injection valve to many cylinder injection fuel according to the present invention, fuel distributed uniform between each cylinder, engine running characteristic are improved, the toxic gas discharging is reduced, and the fuel injection system that reduces of manufacture cost.
