Definitions
- the invention relates to a fuel injection device according to the preamble of the main claim.
- Fuel injectors are e.g. B. for Diesel engines both in stationary systems and in Ship area used. These are fuel injectors with a fuel supply connected and introduce an injector accurately measured amount of fuel under pressure.
- Injection piston pumps are known, for example driven by the camshaft of an engine and where a quantity control, for example via a control edge.
- a quantity control for example via a control edge.
- Rotation of the pump piston with the one arranged on it Control edge over a rule linkage, and this The type of control has proven to be very robust.
- a disadvantage of this injection pump is that failure of the electronic control of the pistons the pump element from an operating position in an emergency position must be turned, the mechanical regulation exclusively in this Emergency position works.
- transitioning from the Normal position to the emergency position is a regulation of Injection pump not possible and it can happen that the adjustment of the piston positioning in an emergency does not work because e.g. B. the Piston adjustment mechanism jams or gets stuck since it has not been operated for a long time.
- the invention is therefore based on the object To create fuel injection system for engines which is an electronic control and a mechanical one Control allowed, the mechanical system of the electronic control system is superior, so that z. B. in the event of failure of the electronic system Transition from electronic to mechanical Stepless control, d. H. immediately, without additional measures or devices required are.
- a fuel injector suggested that normally electronic control of the fuel supply to the fuel injector, being the electronic control system but always a mechanical control system is higher and therefore in the event of a failure of the electronic control without any delay the actual control of the fuel injection quantities makes.
- This fuel injector consists of essentially from a first piston 1, a second piston 2, the first and second pistons 1 and 2 movably arranged in a cylinder 3 or 3A are.
- the first piston 1 is a first fuel inlet 4 assigned and the second piston 2 is a second Associated with fuel inlet 5; at the liquid inlet 4 it can be a supply line, about the z. B. fuel the workspace of the Cylinder 3 is supplied. However, it can also another liquid to the working space of the cylinder 3 are supplied, this liquid advantageously better lubricating properties and has hydraulic properties than the known ones Fuels.
- an appropriate Liquid with better lubricating properties and hydraulic properties is, the mechanical load of the Piston 1, cylinder 3 and control edges 11 of the piston 1, in particular the cavitation on the control edge 11. This will make it usable and extended life of these components.
- the piston 1 is controlled via a Cam 8, which is arranged on a camshaft 9 is, the stroke of the cam 8 for example one shown only schematically in the drawing Push rod 10 is transmitted.
- a control edge 11 is formed on the first piston 1, the one for regulating the amount of fuel is used, and the piston 1 together with the control edge 11 is represented by a schematically Control linkage 12 moves to thereby control to allow the fuel flow.
- the first piston 1 has one with the reference symbol 14 marked stroke and the outlet of the by the first piston 1 is applied amount of fuel made by a control valve 15.
- the control valve 15 is controlled electronically, the open or the closing of the control valve 15 of a computer or microcomputer 21 is regulated, d. H. the computer determines the time when the control valve 15 opened or closed again can be. Through this electronic Control of the control valve 15 is an optimal Regulation of the fuel supply to the Injector 7 allows.
- a check valve 20 arranged so that fuel in the lower area of the Cylinder 3 is supplied only via the 1st fuel inlet 4 can be.
- an overflow valve 22 is arranged so that the Feed pressure over the piston 1 is guaranteed.
- the second piston 2 Downstream of the first piston 1, i.e. H. in the direction the injection nozzle 7, the second piston 2 is arranged, the one indicated by reference numeral 16 Hub executes. As mentioned above, is above of the second piston 2, a second fuel inlet 5 provided, the one located at top dead center second piston 2 by a spring 17 again is pushed down into its starting position.
- the second piston 2 on other Place as arranged from the drawing emerges, for example, it is possible the second Piston 2 with a corresponding cylinder in to arrange the injector 7 or in the fuel line 6. It is also possible to build pressure in the fuel line 6, and thus the delivery rate, to be influenced in time by special Piston designs 2.
- Fuel injector In normal operation, the mode of operation is as shown Fuel injector as follows:
- the pressure in the fuel supply system 4, 5 is relative low.
- the pressure at which the relief valve 22 opens, is slightly higher than the fuel supply pressure, however much less than that of Piston 1 generate pressure.
- control linkage 12 In the operating state shown there is the control linkage 12 is always at the maximum position Performance unless due to a impending overspeed or a so-called "Back-up" operating situation the rule linkage a lower power is set.
- the rule linkage 12 is from an external speed controller and / or a maximum controller set.
- Control valve 15 which can be a solenoid valve, automatically close and would also be in the further course of the different operating states closed. In this state it would be above the moving piston 1 form a fuel column, when moving the first one back and forth Piston 1 a corresponding lifting of the piston 2 would cause. If the piston 2 on his top dead center, the piston 2 is due the spring 17 pressed down again and at a new lifting of the first piston 1 and the amount of fuel above is forced the movably mounted piston 2 is raised again. In the displacement above the piston 2 still through the second fuel inlet Fuel supplied, which then via the nozzle 7 in the combustion chamber of the engine is injected.
- the proposed System even then an injection of Allows fuel, even if the electronics is not functional. If the Electronics becomes fuel injection only by the mechanically controlled injection piston pump carried out and controlled. If however the electronic system is functional, is by the control of the control valve 15th the start of funding and the Delivery rates of the injector controlled, each according to engine and operating conditions, and due to this computer-controlled control of fuel injection times and quantities become special favorable consumption values of the drive motor reached.
- An advantage of the proposed invention is that a relatively simple and inexpensive retrofit from conventional systems to the proposed System is possible because of structural changes essentially only the addition of the second Piston 2 and the addition of the control valve 15 is required. There is no need for elaborate Arrange devices around the piston from one operating position to the other operating position to twist and it is not necessary against the piston cylinder of the first pump element to replace correspondingly trained components.
- Another advantage of the proposed system is that when using a liquid with good Lubrication properties of the piston 1 together with the Control edge 11 before aggressive and abrasive Fuel is protected and therefore a longer one Lifetime has than the known injection pumps.
- Another advantage of the proposed invention is that the principle described is also used can be used for fine control at Control of the intake and exhaust valves of the engine in order Emission values and performance have a positive impact can.
- fuel instead of fuel, one can Liquid for actuating a valve via the proposed device are promoted, wherein also in this case the mechanical position of the Piston 1 electronically by means of the control edge regulated state.
- Control is regulated electronically.
- At this electronic control can be the same or one additional calculator or computing element used be, as for the injection device described above.
- For the actuation of a valve it is also possible to remove a pestle directly from the Actuate or operate piston 2 to the Transfer movement of the piston 2 to the valve. It is understood that when using the proposed device for controlling the Valve movement the control edge 11 of the piston 1 in their training the special requirements for Valve control corresponds.
