Abstract
The invention relates to a fuel injection device for an internal combustion engine having at least two inlet valves (19), comprising an air flow path for supplying combustion air to the inlet valves (19), having two flow channels (24) that are separated from each other, each leading to one of the inlet valves (19), and one fuel injection valve (25), injecting two fuel streams (26) that are offset from one another at an angle, and directed to an injection valve (19). In order to achieve a uniform fuel/air mixture distribution to the two inlet valves (19), each of which is associated with one cylinder (11) of the multi-cylinder combustion engine, despite of the cost-saving use of only a single injection valve for both inlet valves (19), the two fuel streams (26) injected from the injection valve are guided in separate injection channels (27), which have a channel end (271) disposed in one of the flow channels (24).
Description
Technical field
The present invention relates to the fuel injection system of internal-combustion engine that is used to be provided with at least two suction valves according to the preamble of claim 1.
Background technique
Knownly be used to have the fuel injection system (DE 38 08 396 A1) that two suction valves and each suction valve dispose to the internal-combustion engine of one of two combustion cylinders and have a Fuelinjection nozzle that comprises two spray-holes, acute angle of the mutual clamping of its axially bored line obtains two fuel beams that penetrate in different directions thus when fuel distributing.Fuel is injected into combustion air is directed in the sucking pipe on the suction valve, and this sucking pipe branches out the oblique angle breeches pipe in tip side.Each fork of oblique angle breeches pipe props up and is connected on the inlet passage that is formed in the cylinder head, and this inlet passage is sealed by one of two suction valves in tip side.Fuelinjection nozzle be placed into the tube wall of the sucking pipe of oblique angle breeches pipe opposition in so that the spray-hole axis roughly with the axial alignment of fork and thus the fuel beam on the direction of fork, be injected in the volume of air that flows through sucking pipe.
At one also is knownly to be used for the fuel injection system (DE 101 08 541 A1) that its every combustion cylinder is equipped with the internal-combustion engine of two suction valves and to go up the cylinder head that Fuelinjection nozzle is placed into cylinder.The latter has an inlet passage that is connected on the sucking pipe, and this inlet passage has two by a partition wall that extends in wherein towards the firing chamber of combustion cylinder and enters the hole.Each enters Kong Youyi suction valve control.Fuelinjection nozzle is inserted in the cylinder head hole, in acute angle of the passage axis clamping of its axially bored line and inlet passage and the feeding inlet passage.Carry out the insertion of Fuelinjection nozzle in the case like this, promptly last the and fuel beam of a distance that is arranged in before the partition wall that extends in inlet passage of the spray-hole of Fuelinjection nozzle is directed symmetrically towards partition wall with a big injection angle of spread.Fuel is injected in the mixing volume of inlet passage in the partition wall front when Fuelinjection nozzle is opened, and fuel air mixture is inhaled into by the there when INO.
Summary of the invention
Fuel injection system with feature of claim 1 according to the present invention has its advantage, promptly by in the injection channel that separates, two fuel beams that gone out by fuel injection valves inject directly being imported in the fluid passages separately, make under the condition of avoiding leading to the air-flow coupling between the fluid passage of injection valve, to make fuel be positioned at the front of injection valve.Can guarantee on the one hand that thus fuel quantity is assigned on two suction valves extremely equably and is assigned to two equably by in the combustion cylinder of suction valve control and eliminated on the other hand: cause air and fuel to be assigned to the reason of two combustion cylinders unevenly on the known fuel injection system that is provided with the single injection valve that is used for two suction valves, i.e. vibration by air column in two fluid passages is crosstalked the air between the fluid passage.Each fuel beam is ejected in the fluid passage that independent and another fluid passage separates airtightly, occurs the fluid proportional and the injection proportion that are reached as under the situation to an injection valve of a suction valve configuration thus.Although therefore on cost advantageously two combustion cylinders for an internal-combustion engine with multi-cylinders used single injection valve, also can reach same internal combustion engine operation stability and same little internal-combustion engine noxious gas emission.
The favourable further configuration and the improvement of the fuel injection system that can obtain in claim 1, providing by described in other claims measure.
According to an advantageous embodiments of the present invention, two injection channels converge to the grafting chamber that is used for Fuelinjection nozzle with its end of carrying channel outlet.Grafting chamber and injection channel are molded over and comprise an annex that is used for the spliced eye of Fuelinjection nozzle, and this annex is presented in the inlet air flow path in this wise, so that the heart contact is on a leptoprosopy that makes the partition wall that two fluid passages separate in its end face that comprises channel outlet, and can enter receiving chamber from the outside of inlet air flow path.Can make to require separately and make thus to make by such annex and optimize and cost is reduced to the validity of Fuelinjection nozzle and to the difference of the tolerance of mounting point.
Annex is sinking on the mounting point on the end face edge of the section that two partition walls between the fluid passage are exposed, and then annex makes two fluid passages airflow breakaway and two air leakage between the fluid passage are reduced fully again after the installation.Being preferably columniform annex can and both can be installed in the hole that provides in advance accordingly in the sucking pipe by plastics or metal manufacturing and also can be installed in the cylinder head hole.
