Definitions
- the present invention relates to a fuel-supply system for an internal-combustion engine.
- fuel-supply systems of the diesel-cycle type comprise a high-pressure pump that supplies fuel to a common rail, which has a predetermined volume for accumulating fuel under pressure and supplies, in turn, a plurality of injectors associated to the engine cylinders.
- the latter must be brought up to a very high pressure, in the region of 1600 bar, in the conditions of maximum power of the engine.
- the pressure of the fuel required in the common rail is in general defined by an electronic control unit as a function of the operating conditions of the engine.
- a by-pass solenoid valve set on the delivery pipe of the high-pressure pump, is controlled by the control unit for causing recirculation of the fuel that is in excess with respect to the fuel injected by the injectors, towards the usual fuel tank, before said excess fuel enters the common rail.
- the capacity of the high-pressure pumps is directly proportional to the engine r.p.m. and is calibrated so as to meet the maximum requirements in every operating condition of the engine.
- the flow of excess fuel which is discharged into the tank by the by-pass solenoid valve, is very high. Consequently, this embodiment presents the drawback of involving a waste of part of the compression work of the high-pressure pump.
- Variable-capacity high-pressure pumps have been proposed in such a way as to reduce the amount of fuel pumped when the engine functions at reduced power.
- the intake pipe of the high-pressure pump is provided with a restriction having a passage cross-section the area of which is continuously variable.
- Said passage cross-section is defined by a solenoid valve controlled by the electronic control unit as a function of the pressure required in the common rail and/or of the operating conditions of the engine.
- the restriction in the intake pipe is supplied with a constant pressure difference, equal to approximately 5 bar, determined by an auxiliary pump, or low-pressure pump, set in the tank.
- a constant pressure difference equal to approximately 5 bar, determined by an auxiliary pump, or low-pressure pump, set in the tank.
- the aim of the invention is to provide a fuel-supply system for an internal-combustion engine, which will enable limitation or elimination of the drawback set forth above in a simple and inexpensive way.
- a fuel-supply system for an internal-combustion engine 2 for example a four-stroke diesel engine.
- the engine 2 comprises a plurality of cylinders 3, for example four cylinders, which co-operate with corresponding pistons (not shown), which can be actuated to turn a drive shaft 4.
- the common rail 6 is supplied with fuel under high pressure by a high-pressure pump, designated as a whole by 7, via a delivery pipe 8.
- the high-pressure pump 7 is supplied by a low-pressure pump, for example, an electric pump 9, via an intake pipe 10 of the high-pressure pump 7.
- the electric pump 9 is in general set in the usual fuel tank 11.
- a discharge pipe 12 gives out into the tank 11 for causing recirculation of the excess fuel of the supply system 1.
- the common rail 6 is provided with a discharge solenoid valve 15, which is in communication with the discharge pipe 12 and performs a safety function in the case where there were to be an overpressure in the common rail 6.
- Each injector 5 is designed to inject, into the corresponding cylinder 3, an amount of fuel that ranges between a minimum value and a maximum value, under the control of an electronic control unit 16, which can be formed by the usual microprocessor control unit for control of the engine 2.
- the control unit 16 is designed to receive signals indicating the operating conditions of the engine 2, such as the position of the accelerator pedal and the r.p.m. of the drive shaft 4, which are generated by corresponding sensors (not shown), as well as the pressure of the fuel in the common rail 6, detected by a pressure sensor 17.
- the control unit 16 controls the instant and duration of actuation of the individual injectors 5.
- the control unit 16 controls opening and closing of the discharge solenoid valve 15. Consequently, the discharge pipe 12 conveys towards the tank 11 both the discharge fuel of the injectors 5 and the possible excess fuel in the common rail 6, discharged for safety reasons by the solenoid valve 15.
- the piston 21 is actuated by an eccentric 22 carried by an actuation shaft 23 of the high-pressure pump 7.
- the two pumping elements 18 are coaxial and opposite to one another, and are actuated by a single eccentric 22.
- the shaft 23 is connected to the drive shaft 4, via a motion-transmission device 26, such that the eccentric 22 controls a compression stroke of a piston 21 for each injection of the injectors 5 into the respective cylinders 3 of the engine 2.
- the fuel is at atmospheric pressure.
- the electric pump 9 compresses the fuel to a low pressure, for example in the region of just 2-3 bar.
- the high-pressure pump 7 compresses the fuel received from the intake pipe 10 so as to send the fuel at high pressure, for example in the region of 1600 bar, to the common rail 6, via the delivery pipe 8.
- the capacity of the high-pressure pump 7 is controlled exclusively by a solenoid valve 27 arranged on the intake pipe 10.
- the solenoid valve 27 is of the on-off type and has an effective passage cross-section that is relatively wide so as to supply fuel without causing any drop of pressure when it is open.
- the solenoid valve 27 (partially illustrated) comprises a casing 28 and a plate-like portion 31, which is coupled in a fixed position to the casing 28, for example via an externally threaded ringnut 31a screwed to a side wall 36 of the casing 28.
- the plate-like portion 31 has a hole 32, which extends along an axis 33 and defines an inlet for the fuel that arrives from the delivery of the pump 9.
- the chamber 37 houses an open/close element 40, which is defined by a ball or by a spherical portion, in the particular example shown.
- the open/close element 40 is subject to the opposite actions of a spring 42 and of an electric actuator 43.
- the actuator 43 is defined by an electromagnet comprising: a magnetic core 44 fixed with respect to the casing 28; and an armature 45, which impinges upon the open/close element 40 so as to keep it in a closing position when the electric actuator 43 is not energized, transferring onto the open/close element 40 the elastic force of the spring 42.
- the open/close element 40 is spherical, the travel allowed for the armature 45 is of a small amount so that there is no possibility for the open/close element 40 to be able to displace radially.
- the spring 42 has a pre-load and a stiffness such as to exert an action of axial thrust that tends to bring the armature 45 into a lowered position and, hence, the open/close element 40 into the closing position.
- the open/close element 40 engages in a fluid-tight way a valve seat 47 defined by a conical surface provided on the plate-like portion 31 around the hole 32 so as to close the hole 32 itself.
- the spring 42 is housed in the magnetic core 44 and acts directly on the armature 45.
- the magnetic core 44 When the magnetic core 44 is electrically supplied, it causes axial translation of the armature 45 into the raised position, and hence causes displacement of the open/close element 40 into an opening position.
- the hole 38 In the opening position, the hole 38 communicates with the hole 32 through the space or volume of the chamber 37 for supplying fuel from the pump 9 to the intake valves 25 of the high-pressure pump 7.
- FIG 3 is a partial illustration of a variant of the solenoid valve 27, the components of which are designated by the same reference numbers used in Figure 2 , wherever possible.
- the guide element 36a is a casing portion that is defined by the prolongation of the wall 36 towards the actuator (not illustrated in Figure 3 ) and is slidably coupled directly to the wall 40b of the open/close element 40.
- the wall 36 is provided with at least two radial holes 38, which are set in diametrally opposite positions with respect to one another.
- the plate-like portion 31 is fixed to the wall 36 underneath holes 38 for interference fit, for example via drive fit, and has a plane face that is orthogonal to the axis 33, faces the wall 40a, and defines the valve seat 47.
- the spring 42 is at least partially housed in the open/close element 40, is coaxial with respect to the wall 40b, and acts directly against the wall 40a.
- the wall 40a comprises an annular projection 46, which is coaxial to the hole 32, is set in a more internal position with respect to the holes 48 and has the purpose of guaranteeing fluid-dynamic sealing against the valve seat 47 so that the sealing area has the mean diameter of the projection 46.
- the open/close element 40 comprises a projection 49, which is set along the perimetral edge of the wall 40a, i.e., in a position more external respect to the holes 48 and to the projection 46, and has radial passages not visible in Figure 3 .
- the invention applies both to systems where the solenoid valve 27 is controlled in a way synchronous with the rate of rotation of the pump and to systems where the control of the solenoid valve 27 is asynchronous.
