Definitions
- the present invention relates to a fuel valve for large turbocharged two-stoke diesel engines, in particular to en electronically controlled fuel valve for the large turbocharged inflow two stroke diesel engines with cross heads.
- These engines are typically provided with two or three fuel valves arranged in each cylinder cover.
- the fuel valve is provided with a spring biased axially movable valve needle that acts as a movable valve member.
- a preset pressure typically 350 Bar
- a conventional nozzle has a longitudinal axis that is arranged roughly at an angle of 10 to 15 deg to the direction of the movement of the piston in the cylinder of the engine and the nozzle is provided with a central bore and a plurality of nozzle bores that direct the fuel away from the cylinder walls and into the combustion chamber.
- the nozzle bores are directed to inject the fuel with the flow of the swirl although some of the bores may be directed to inject the fuel against the flow of the swirl.
- a known fuel valve of this type is the MAN Diesel slide fuel valve that has a design with a minimized sac volume of residual fuel.
- This known fuel valve has two positions: open with all nozzle holes in use or closed.
- the position of the axially movable valve needle is controlled by a pressure chamber in the valve housing above the axially movable valve needle.
- the pressure chamber is permanently connected to a high pressure fluid source via a throttled connection, and to a drain via a closable throttled connection. This construction causes substantial drain loses during valve open time and causes relatively slow closing and opening speeds of the fuel valve.
- the high pressure fluid for controlling the needle valve is the fuel oil.
- WO 2008/071187 discloses such a fuel valve corresponding to the preamble of claim 1.
- a conventional fuel valve for a large two stroke uniflow diesel engine with cross-heads the opening and closing of the valve needle of the fuel valve is controlled via a pressure chamber arranged in the fuel valve housing at an end of the valve needle that is opposite to the nozzle.
- the valve needle is slidably and sealingly received in a bore in the fuel valve housing with the pressure chamber forming the end of the bore.
- the pressure in the pressure chamber is controlled by a throttled connection to the high pressure fluid inlet port and another throttled connection to the tank port.
- the connection to the tank port can be opened and closed by an electrically controlled solenoid valve that typically is a solenoid controlled ball valve.
- the throttled connection to tank is less restricted than the throttled connection to the fuel port, and therefore pressure drops in the pressure chamber when the solenoid valve opens the connection to the tank port.
- the speed with which the valve needle opens and closes is determined by the restrictions, and both the opening and closing movement of the valve needle is inherently slower than desired.
- the solenoid valve is open during a fuel injection event.
- the flow through the restricted connections when the solenoids valve is open represents a large leak flow and the energy loss associated with this leak flow is quite substantial since the pressure at the fuel inlet is very high, typically 300 bar or higher.
- US 7 249 591 discloses a fuel injection apparatus for an internal combustion engine with a pressure intensifier for intensifying pressure of fuel from a fuel injection pump, a fuel injection nozzle for injecting fuel having intensified pressure into a cylinder of the internal combustion engine, a solenoid valve for performing control of intensifying pressure of the pressure intensifier or control of opening or closing the fuel injection nozzle, a first fuel discharge path through which fuel flowing out of the pressure intensifier or the fuel injection nozzle bypasses the solenoid valve to return the fuel to a low pressure side of a fuel system, and a second fuel discharge path through which fuel flowing out of the solenoid valve bypasses the first fuel discharge path to return the fuel to a low pressure side of the fuel system.
- the fuel valve in this known fuel injection apparatus for a normal size diesel engine e.g. this fuel valve is not suitable for large turbocharged two-stroke diesel engines with crossheads because it does not have a nozzle with a closed end and has a nozzle hole arrangement that would result in spraying fuel onto the cylinder walls and on the top of the piston if it were fitted in a large two stroke diesel engine without modification and because this known valve is not provided with a cut-off shaft moving in unison with the valve needle, and an arrangement without a cutoff shaft would in a large two-stroke diesel engine due to the size of the nozzles lead to inacceptable amounts of residual fuel entering the combustion chamber prior to the planned injection event.
- the fuel valve disclosed in US 7 249 591 is not generic. The same applies to the fuel injection apparatus disclosed in DE 10 2008 043 985 A1 .
- the present demand for lower emissions and improved specific fuel oil consumption require faster reacting fuel valves and reduced energy losses through leak oil
- the present invention defines a fuel valve for injecting fuel into the combustion chamber of a large two stroke diesel engine, with a resiliently biased and axially movable valve needle cooperating with a valve seat, an electronically controlled pilot valve connected to a closing chamber for urging the needle valve to its seat for selectively, e.g. alternatingly, connecting the closing chamber to a tank port or to a fuel inlet port.
- the solenoid valve is a solenoid controlled ball valve. This construction allows for the use of an off-the shelf type solenoid valve to control the position of the spool.
- the restricted connection to the tank port is located inside the valve housing.
- the restricted connection to the tank port is located extends through the spool of the spool valve.
- the nozzle is a nozzle with an axial bore and a closed front and the valve needle moves in unison with a cut-off shaft moving in unison with the valve needle and received axially displaceable in the central bore in the nozzle for opening and closing the nozzle holes.
- the fuel valve 1 according to an exemplary embodiment illustrated in Fig. 1 has an external housing 10 which at its rearmost end has a fuel inlet port 16 and a fuel outlet port or tank port 18.
- the inlet port 16 is to be connected to a source P of high pressure fuel such as fuel oil, heavy fuel oil from a fuel pump or from a common fuel rail.
- the outlet port 18 is to be connected to a return line to tank T.
- the fuel valve 1 may in a known manner be mounted in the cylinder cover of a large two-stroke turbocharged uniflow diesel engine with cross-heads and be connected with a fuel pump, not shown.
- the fuel inlet port 16 is in flow connection with a duct 17.
- Duct 17 extends to the seat of a valve needle 20 that is axially displaceable in an axial bore in the valve housing 10.
- the valve needle 20 is biased to its seat 22 by a closing spring 23.
- the foremost part of the valve housing 10 holds a nozzle 30 that projects from the valve housing 10 and into the combustion chamber of the engine cylinder (not shown) when the fuel valve 1 is mounted on the cylinder cover.
- Fig. 1 shows the valve needle 20 resting on the valve seat 22. In this position, fluid flow of fuel from the fuel oil inlet port 16 to the nozzle 30 is blocked. A chamber 25 above the valve seat 22 is connected to duct 17 to receive pressurized fuel.
- the valve needle 20 carries a foremost cut-off shaft 40 that is thinner than the rearmost section of the valve needle 20 and the cut-off shaft 40 projects into a central bore 33 in the nozzle 30.
- the cut-off shaft 40 is axially displaced in the central bore of the nozzle 30.
- the nozzle 30 is further provided with a plurality of nozzle holes 35 through which the fuel is injected into the combustion chamber from the central bore 33. Thus, during a fuel injection event a jet of fuel comes from the nozzle holes 35.
- the cut-off shaft 40 is in an exemplary embodiment made as one piece of material with the valve needle 20.
- the cut-off shaft 40 is hollow and the hollow interior of the cut-off shaft 40 connects to the space downstream of the valve seat 22. Thus, when the valve needle 20 is lifted from its seat the flow path extends all the way from the fuel oil inlet 16 to the hollow interior of the cut-off shaft 40.
- a duct 19 is connected to the outlet port 18 and the duct 19 collects the return oil flow as will de explained in greater detail hereafter.
- the foremost part of the cut-off shaft 40 is cylindrical and fits exactly into the central bore 33.
- the upper (upper as in the drawings) part of the valve is a substantially cylindrical section 43 with an enlarged diameter and this section 43 that is slidably received in an axial bore 45 in the valve housing 10 so that the section 43 can act like a piston in the valve housing 10.
- a closing chamber 46 formed in the upper part (upper as in the drawing) of the valve housing 10 is disposed above the actuation section 43.
- the spring 23 for urging the valve needle 20 onto its seat 22 is received in the closing chamber 46, and acts on the top of the actuation section 43.
- the pressure in closing chamber 46 acts on the valve needle 20 to urge the latter in the closing direction with an effective surface area A1.
- Opening chamber 70 for urging the valve needle 20 in the opening direction is located under section 43 and connected via bore 72 to duct 17. Opening chamber 70 is therefore always pressurized when the fuel inlet port 16 is connected to a source of pressurized fuel (such as a fuel pump). The pressure in opening chamber 70 acts on the valve needle 20 to urge the latter in the opening direction with an effective surface area A2.
- a bore 52 is formed in the valve housing. In figure 1 the bore is oriented axially. However, other orientations for bore 52, such are radially or tangentially or orientations there in-between are also possible.
- a spool or slide 53 is slidably received in the axial bore 52 and the position of the spool 53 determines the flow to- and from three ports that open into the axial bore 52.
- One of the ports connects via a conduit 57 to duct 17 that is connected the source of pressurized fuel via fuel inlet port 16.
- Another port is connected to duct 19 by a conduit 58 and the third port is connected to closing chamber 46 via a control conduit 59.
- a reduced diameter section 55 of the spool 53 connects the control conduit 59 with conduit 57 in the lower (lower as in the drawing) position of the spool 53 and connects the control conduit 59 to conduit 58 in the upper (upper as in the drawing) position (shown in Figure 1 ) of the spool 53.
- closing chamber 46 is connected to the outlet port or tank port 18 (drain) and in the lower position of the spool 53 the closing chamber 46 is connected to the source of pressurized fuel (high pressure).
- the upper (upper as in Figure 1 ) section of the spool 53 is formed as a piston section 73 with a diameter that is larger than the diameter of the rest of the spool 53 (in other embodiments the diameter of the upper section 73 of the spool 53 is equal or smaller than the diameter of the rest of the spool 53).
- a pressure chamber 75 above acts on the spool 53 in the downward (downward as in Figure 1 ) direction to urge the spool 53 to the position where closing chamber 46 is connected to the source of pressurized fuel (high pressure) P.
- a restricted connection 82 e.g. in the form of a conduit with an orifice 84 that acts as a throttle connects pressure chamber 75 to duct 19 and thus to the tank port 18 (drain).
- the restricted connection can be opened and closed by a ball valve 85 that is connected to a spring biased solenoid 88.
- the spring of the ball valve 85 urges the ball valve to its seat.
- Activation of the solenoid 88 causes the ball to be lifted from the seat against the action of the spring 89.
- a restricted connection e.g. in the form of a conduit with 83 an orifice 86 that acts as a throttle connects pressure chamber 75 to duct 17 and thus to the fuel inlet port 16.
- the position of spool 53 is controlled by fuel oil pressure and the balance between the orifices 84 and 86.
- valve seat of the ball valve 85 When the solenoid 88 is activated the valve seat of the ball valve 85 is opened and pressure chamber 75 is connected to the outlet port 18 (drain) via the orifice 84.
- the fuel oil pressure in the pressure chamber 75 will drop because the flow area of orifice 86 is smaller than the flow area of orifice 84.
- the decrease pressure in pressure chamber 75 will cause the spool 53 to move upwards under influence of the pressure in pressure chamber 77 and closing chamber 46 will be connected to duct 19 and the outlet port 18 via control conduit 59.
- a ring chamber 93 below the piston section 73 is connected to duct 19 via a conduit 95 and hence to the tank port. Thus, no force will act on the annulus area of the piston section 53.
- the spool 53 acts as a 3/2 way valve, hence the spool 53 can be replaced by ball valve or a seat valve.
- the spool 53 is replaced by a ball valve and in another embodiment the spool 53 is replaced by a seat valve.
- the solenoid 88 can in an embodiment be connected to an electronic control unit 50, such as the electronic control unit of the engine. Hence the electronic control unit 50 determines if the solenoid 88 is active or not and thereby the electronic control unit 50 controls the start and end of a fuel injection event.
- the spool 53 is connected directly to an electronic actuator and then controlled according to the movement of the actuator.
- Figure 2 shows an embodiment of the invention that is essentially identical to the embodiment of figure 1 , except that the valve needle 20 is not provided with a cut off shaft.
- the construction of the nozzle 30 and the valve needle is more simple than in the embodiment of Figure 1 .
- the sac volume in the nozzle 30 is larger than in the embodiment of Figure 1 .
- One advantage of the teaching of this disclosure is that it provides for a fuel valve for a large two-stroke diesel engine that allows for precise control of a fuel injection event. It is another advantage of the present fuel valve that it reduces leak oil losses. It is yet another advantage of the of the present fuel valve that it provide for a faster response of the valve needle on control signals.
