Definitions
- the invention relates to a fuel injector according to the preamble of
- Such a fuel injector is known from DE 10 2006 049 830 A1
- the injector has, within an injector housing, a control chamber in which the end of a nozzle needle opposite an injection opening is inserted.
- the control chamber is formed via an inlet channel designed as an inflow bore with a
- the control chamber is used in a known manner to the opening and closing movement of the
- Nozzle needle is injected into the combustion chamber of the internal combustion engine depends inter alia on different fuel properties.
- Fuel properties in turn depend on the type of fuel and the environmental conditions. For example, the viscosity of both the type of fuel (winter diesel, summer diesel, mixtures of various
- the viscosity of the fuel is usually higher than when the engine is at operating temperature. This has the consequence that, without influencing the injection parameters during the cold start, too little fuel is usually injected into the combustion chamber. It is therefore necessary or desirable, during the warm-up phase of the engine or the internal combustion engine, the fuel quantity during an injection process of a relatively high value due to the low
- inlet bore into the control chamber is shown as an elongated bore, in practice, however, within the diameter / length ratio of approximately 1: 2.5 having inlet bore to influence the flow rate, a flow constriction in the form of a diaphragm is formed. This diaphragm causes the fuel flowing out of the high-pressure chamber into the control chamber to continue to flow turbulently after passing through the diaphragm. From the
- the present invention seeks to further develop a fuel injector according to the preamble of claim 1 such that during a Einspritztaktes a
- Injector valve member in particular during the warm-up phase of the internal combustion engine, a target injection amount despite different Viscosities of the fuel at different temperatures in the
- Combustion chamber of the internal combustion engine can be achieved with the least possible effort. In particular, it should be achieved that even at a relatively high viscosity, i. at a relatively low temperature of the fuel, the desired injection quantity is achieved.
- Inflow channel via which a post-flow of fuel from the high-pressure chamber takes place in the control chamber of the fuel injector, is formed to form a laminar flow.
- the invention is based on the finding that in the presence of a laminar flow the
- Flow rate through the inflow channel is viscosity-dependent.
- a flow which is reduced compared to a lower viscosity is made possible. This has the consequence that the pressure in the control chamber when opening the Abiaufbohrung falls faster or faster, since the inflowing over the inflow channel fuel with less
- Flow rate (per unit time) flows through the inflow channel.
- the at least one inflow channel at least two, preferably a constant diameter having first
- throttle bores in the element wherein the diameter / length ratio of the at least two throttle bores is less than 1: 5, preferably about 1:10.
- the diameter / length ratio should be about 1: 15.
- control chamber is usually formed by an annular circumferential wall portion of a valve piece, or by a voltage applied to a throttle plate in the axial direction control chamber sleeve. Both the minimum wall thickness of the control chamber sleeve and the valve piece is given for pressure or strength reasons and is usually chosen as small as possible. Now to the desired
- Control chamber sleeve to effect the desired throttle function and on the other hand, for example, in full load operation to take into account that enough fuel can flow into the control chamber, that is, the fuel! Njektor has a desired high dynamics.
- the at least two throttle bores are arranged at regular angular intervals from one another.
- the at least one inflow channel comprises at least one groove formed in the injection member between the control chamber and the high-pressure chamber on the lateral surface of the injection member whose width / depth ratio is smaller 1: 10, preferably about 1: 20.
- Throttle bore dispensed with these and instead of a targeted
- Fuel causes from the high-pressure chamber in the control room.
- This solution has a constructive extent in that the strength of the valve piece or the control chamber sleeve is not weakened by throttle bores, and that on the other hand by the usually relatively long in the axial direction of the injection member formed guide a single groove is sufficient to the viscosity-dependent throttling effect of To realize inflow channels.
- Section passes, which has a smaller diameter compared to the first section.
- the at least one inflow channel has one in the
- Injection member formed second throttle bore comprises, wherein the
- Diameter / length ratio of the throttle bore is less than 1: 5, preferably about 1:10.
- This variant supplies the fuel via a throttle bore formed, for example, in the longitudinal axis of the injection member (nozzle needle), which is then connected to the high-pressure chamber, for example via a transverse bore.
- the injection valve member may have a substantially constant diameter or that no mechanical processing is required on the peripheral surface of the injection valve.
