Definitions
- the present invention relates to a fuel injection device for a diesel engine that performs fuel injection into a combustion chamber of the engine using a common rail in fuel injection of the diesel engine.
- an injection pump and a nozzle are integrally configured, and the fuel injection nozzle (unit) is mounted on a cylinder head for each cylinder.
- a relatively high-pressure fuel is stored in the common rail, which is a pressure chamber, using a toy injector, and this fuel is further boosted by the booster piston that forms the fuel injection pump.
- a common rail system is used to inject fuel from the fuel injection nozzle.
- the fuel in the fuel tank 11 is pressurized by the fuel supply pump 3 and the pressure is adjusted by the pressure control valve 10 controlled by the controller 13 as shown in Fig. 3. It is stored in the common rail 4 which is the accumulator.
- the fuel in the common rail 4 is injected into the combustion chamber 15 from the fuel injection nozzle 6 via the fuel pipe 5 and the solenoid valve 14. Adjustment of the injection amount and injection timing of this fuel injection is performed by inputting signals from various sensors 12 The control is performed by controlling the opening and closing of the solenoid valve 14 by the controller 13.
- the fuel pipe 5 connecting the discharge port 7 of the common rail 4 and the fuel injection nozzle 6 is provided to prevent the pressure response of the fuel injection nozzle 6 from fluctuating. It is necessary to make the length of all the fuel pipes 5 uniform so as not to disturb the fuel.
- the fuel supply pump 3 and the common rail 4 are connected to the cylinder head. It is arranged in a plane on the upper surface without overlapping.
- this fuel pipe 5 in order to supply fuel at a constant pressure to the fuel injection nozzle 6, this fuel pipe 5 must be aligned with the longest pipe length in order to make the response of loss and pressure uniform. Therefore, the entire fuel pipe 5 becomes long, and the work during assembly and maintenance becomes complicated. In addition, since the length of the fuel pipe 5 from the common rail 4 as the pressure source to the fuel injection nozzle 6 becomes longer as a whole, there is a problem that the responsiveness of the injection pressure is reduced accordingly. For these fuel pipes 5, it is necessary to use thick high-strength metal pipes that are arranged in the vibrating engine 1 and that can withstand high pressure and vibration in order to send high-pressure fuel. When the length of the fuel pipe 5 is increased, there is a problem that the weight of the fuel pipe 5 as a whole is not negligible.
- the present invention has been made in order to solve the problems of the conventional engine, and an object thereof is to eliminate the need for a bracket structure for a common rail and a fuel supply pump, In addition, by arranging the common rail so that the fuel piping is shortened as a whole, the fuel injection device of the diesel engine with a small space, a small number of parts, a light weight, and easy maintenance is provided. To provide.
- the fuel of the diesel engine of the present invention is In the fuel injection device, a common rail is mounted on the cylinder body, and a fuel supply pump is mounted on the common rail. The fuel is then injected into the fuel chamber of the cylinder.
- the longest distance between each discharge port of the common rail and the fuel injection nozzle arranged in the combustion chamber of each cylinder is reduced. Since the length can be shortened, the length of the fuel pipe corresponding to the longest distance can be shortened.
- piping can be symmetrically arranged not only in the longitudinal direction but also in the lateral direction. The number of parts can be reduced.
- FIG. 1 is a schematic configuration diagram of a common rail system showing an embodiment of the present invention, in which (a) is a plan view and (b) is a front view.
- FIG. 2 is an assembly explanatory view showing attachment of a common rail and a fuel supply pump according to the embodiment of the present invention.
- FIG. 3 is a configuration diagram showing an outline of a common rail system.
- FIG. 4 is a schematic diagram showing an example of a conventional common rail system.
- FIG. 5 is a schematic diagram showing another example of the common rail system of the prior art.
- the fuel injection device for a diesel engine according to the present invention is mounted on a cylinder body 2 by bolts 8a.
- a common rail 4 is mounted, and a fuel supply pump 3 for pumping fuel to the engine is mounted on the common rail 4 to assemble a multilayer structure with a bolt 8b. Then, the fuel pumped by the fuel pump 3 is accumulated in the common rail 4 and then supplied to the individual fuel injection nozzles 6 to be injected into the combustion chamber 15 above each cylinder. Make up.
- the common rail 4 itself also serves as a bracket for mounting the fuel injection pump 3.
- the common rail 4 may be provided with a pressure control limiter, a temperature sensor, a pressure sensor, and the like, if necessary.
- FIG. 2 only two outlets 7 that lead from the common rail 4 to the fuel injection nozzle 6 are shown for the sake of simplicity.
- the piping between the common rail 4 and the common rail 4 is also omitted, but it goes without saying that the number of the discharge ports 7 is provided in accordance with the number of cylinders, and the fuel supply pump 3 and the common rail 4 are connected to each other. A pipe between them will also be provided.
- the shape of the fuel supply pump 3 is also schematically illustrated, the fuel supply pump 3 has a driving force from the crank shaft at its longitudinal end, for example, at the near side in FIG. It is configured by providing a cutting mechanism etc.
- the common rail 4 is arranged at a position where the longest distance of the pipe length between the discharge outlet 7 and the fuel injection nozzle 6 provided in the combustion chamber above the cylinder 9 is reduced. Specifically, it is located at the center of Engine 1 in the longitudinal direction.
- the common rail 4 is positioned at the center of the engine 1 in the longitudinal direction. And at the center of the V-knock, that is, at the center in the width direction of the cylinder block.
- the fuel pipe 5 is symmetric not only in the longitudinal direction but also in the width direction, and the number of fuel pipes 5 that can be commonly used is increased. Can be reduced.
- the common rail 4 is directly mounted on the cylinder body 2, and the common rail 4 itself is used as a bracket of the fuel supply pump 3 to supply fuel. Pump 3 is mounted on common rail 4. Therefore, both the brackets for the common rail 4 and the fuel supply pump 3 can be omitted.
- the work of assembling and maintaining the common rail 4 and the fuel supply pump 3 to the cylinder body 2 can be simplified, and the workability during assembly and maintenance of the engine 1 can be improved. Can be.
