Abstract
A connecting element 4 has a first inlet 2 for a fuel line and a second inlet 3 for a second fluid, preferably water, the first inlet 2 leading to a flow passage 5 which is surrounded by an annular space 31 into which the second fluid is discharged and nozzle bores at the periphery of the flow passage 5 connecting the annular space 31 with the flow passage 5; the nozzle bores being arranged at an acute angle to an axis coaxial to the flow direction of the fuel in the fuel passage 5. The outlet 12 of the flow passage 5 may be directly attached to a fuel injection nozzle 1. Preferably a nozzle insert 18 is placed in the flow passage 5 separating the annular gap 31 from the flow passage 5 and through which the nozzles bores pass. The nozzle bores may co-operate with grooves in the flow passage 5 to increase turbulence and assist the emulsifying effect. The fuel-water ratio is a function of engine operating conditions.
Description
1 J is 1 CONNECTING ELEMENT FOR THE INLET OF FUEL AND A SECOND FLUID INTO
AN INJECTION VALVE 2320060
The invention relates to a connecting element for the inlet of fuel and a second fluid, which in particular is insoluble in the fuel, into the fuel intake of an injection valve of a diesel engine having the features indicated in the preamble of Claim 1.
A connecting element of this type is known from WO 88/01019, in which it is fully integrated into the nozzle holder of the injection valve which together with the injection nozzle forms the fuel-injection valve. The connection for a second fuel discharges at an angle into the section of the fuel-intake bore to the injection nozzle provided in the nozzle holder. In addition to extensive modifications to the nozzle holder, this connecting element requires additional construction space for the connection of the supply line for the second fuel disposed radially on the nozzle holder. Depending on the installation conditions of individual engines, in this device structurally expensive modifications to the existing cylinder head and/or adjoining supply systems are required. Another disadvantage of the connection formed in the nozzle holder arises just from the inlet of the second fuel via the opening cross-section of a bore into the fuel intake. This does in fact result in interstratification of the second fuel in the high-pressure duct during the injection intervals but in this case charge lamination also takes place which in the following highpressure stages is gradually conveyed to the injection opening. It is not possible to have a supply to the injection nozzle, which is dependent on engine operation, with uniform mixing of fuel and the second fluid, independently of the metered quantities of fluid, via the intake to the injection nozzle.
DE-PS 969 853 discloses a preferably sharply tapered connecting element which is screwed into the injection 2 nozzle body. Two bores are formed in the connecting element, to which corresponding feed ducts are connected, on the one hand, and which, on the other hand, at an intersection downstream unite at an acute angle with an axially arranged main duct. The feeds for the different types of fuel to the injection nozzle are here designed to be correct in respect of flow and with the lowest possible losses. Optimum mixing of the fuels is also not provided thereby.
On the other hand, DE 44 14 488 Cl discloses an emulsifier device in which satisfactory intermixing with the liquid present therein is effected by a discharge of second fluid spaced apart over the periphery into a swirl chamber. An emulsifier device of this type is expensive in construction and is designed for the formation of an is emulsion with the most uniform possible proportions of the fluids contained therein. Mixture variations dependent on engine operation are just as unlikely to be found in such a device as individual inlet or feed to the cylinders.
Therefore, the invention set out in Claim 1 is based on the problem of feeding a mass flow of a second fluid, which is metered depending on engine operation and which is subject to large fluctuations, to an injection nozzle mixed in a uniformly satisfactory manner with the fuel intake, in a manner which is simple in respect of apparatus and which is economical.
