Definitions
- the invention relates to a device for injecting fuel for a reciprocating piston internal combustion engine according to the preamble of claim 1 and a reciprocating internal combustion engine with such a device.
- EP-A 0 690 222 describes a device for injecting fuel described having a metering piston by a fuel pump Fuel under high pressure up to 2,000 bar and one Contains control piston, which has guide elements for the fuel.
- the Control piston is powered by a hydraulic system between two End positions shifted, which is regulated electrically.
- the fuel will Via the guide elements from a fuel pump to the dosing room or from Dosing chamber of the injector of a cylinder one Reciprocating internal combustion engine supplied.
- the guiding elements are like this arranged that in none of the end positions a connection at the same time to both the fuel pump and the injector of a cylinder consists.
- the invention has for its object a device for injection of fuel for a reciprocating internal combustion engine to create a individual control of the injection nozzles.
- control valves is used to control the Injectors for register and stutter injection and / or shutdown enables one or more injection valves of an engine cylinder. At the The machine can fail all the injection nozzles of an engine cylinder be driven with the remaining cylinders at partial load.
- Injection volume can be kept constant. If the distance measurement fails the injection is time-controlled. Becomes an ignition pressure measuring device applied, the ignition pressure to the permissible value can be regulated, so that always the cheapest Fuel consumption is achieved.
- the injection device contains a pressure booster 1 and one Control slide 2, which are displaceable between two end positions and a control valve 3 and a hydraulic-electrical device 4.
- the Pressure booster 1 is designed as a stepped piston, the two pistons 7, 8 with has different diameters.
- the pistons 7, 8 are each in one Chamber 9, 10 slidably arranged, the chamber 9 for the Larger piston 7 via a channel 11 with the spool 2 in Connection is established and the chamber 10 for the smaller piston 8 a channel 12 with the control valve 3 and via a channel 13 with a Arrangement 14 for supplying fuel, e.g. Diesel fuel or Heavy oil is related.
- In the chamber 9 there is an elastic means 15 arranged, which holds the pressure booster 1 in an end position.
- the end position is the connecting channel 11 to the control slide 2 completed and the connecting channels 12 and 13 to the control valve 3rd or to the arrangement 14 for supplying fuel open.
- the Control slide 2 is arranged in a cylindrical chamber 21, the one Feed channel 22, the consumer channel 11, which leads to the pressure booster 1 and a drain channel 24 and a channel 25 on the end faces Has pressure medium and a channel 26 for the leak.
- the spool 2 is cylindrical and has two control edges 32, 32 to control the flow to control a medium.
- the control valve 3 has an on / off function and has a valve body 41 with a seat, a feed channel 42 for Fuel, a return channel 43 and a consumer channel 44, one Valve slide 45 with a valve cone 46 and a known drive 47 for the valve slide.
- the hydraulic-electrical device 4 comprises several hydraulic pumps 51 (only one shown), one accumulator 52, Pilot valves 53, 54 for the control slide 2 and the control valve 3, an angle encoder 55, both the angle of rotation and the Crankshaft position indicates means 56 for sensing the position of the pressure booster and control electronics 57, which with the Pilot valves 53, 54, the angle encoder 55 and the device 56 is connected to transmit signals.
- the device 56 is advantageous as inductive measuring system. It is also possible to use other measuring systems, e.g.
- lines 61 branch off from the accumulator 52, each for a cylinder of a reciprocating piston internal combustion engine are provided, the cylinder being one or more injectors can have.
- the line 61 is connected to the feed channel 22 of the Control spool 2 and the pilot valves 53, 54 connected.
- a line 62 is provided for each Exhaust valve (not shown).
- pressure booster 1 is connected to the control valve 3.
- control valves 3 with the pressure booster 1 be connected.
- the pressure booster does two jobs, one Dosage and an increase in fuel pressure for everyone Injection process.
- the fuel is dosed by means of Means 56 that continuously determine the path of the shift and as Apply signals to control electronics 57. From the cross-sectional area of the smaller piston 8 of the pressure booster 1 and from the covered The displaced volume is determined and thereby a volumetric one Injection realized.
- Control electronics cause fuel injection into one Suppress cylinder with damaged injector and if necessary to reduce the total engine load and / or the error with one Display device to display.
- the hydraulic pumps pump up control oil a pressure of about 100 to 300 bar in the accumulator 52.
- the in this Energy contained in oil is used to operate the items in question here Device used.
- the figure shows the device in the state before an injection, at which the arrangement 14 supplies the pressure booster 1 with fuel which is under a pressure of approx. 10 bar and the injection can use, which proceeds as follows.
- the control oil flows into the larger chamber 9 of the pressure booster 1 and moves the step piston, so that in the smaller chamber 10 existing fuel is displaced.
- the little one Chamber 10 on the one hand by a check valve in the arrangement 14 and on the other hand, is closed by the closed control valve 3 a pressure built up that corresponds to the area ratio of the stepped piston corresponds.
- the Valve slide 45 actuated and the control valve 3 opened, so that the Fuel flows to the injector.
- the injection process is quickly ended.
- control slide 2 After completion of the injection process, the control slide 2 is in the Rested position so that the control oil from the larger Drain chamber 9 of pressure booster 1 via channels 11 and 24 can. This provision is from the means 15 and the new in the smaller chamber 10 of the pressure booster 1 flowing fuel supported.
- the device contains a metering piston, which acts as a pressure booster (1) a stepped piston is configured to set a fuel quantity and bring to injection pressure and at least one control valve (3) to to supply one or more injection nozzles (5) with fuel.
- the Pressure booster (1) and the control valve are electrically regulated hydraulic system operated by a pump with working oil at a much lower pressure than the injection pressure is applied.
- the control valves (3) create an individual Injection enables.
