Description

Editorial Note 2001100579 Page 2 of the specification is the claims page.
Page 1 11-11-2001 Patent for Diesel Fuel Injection Pump Rack Position Controller Specification Description: 1. The Diesel Fuel Injection Pump Rack Position Controller is a device that is connected to the original diesel engine Injection pump rack. By mechanical (cable, linkage, hydraulic, air assisted or direct coupling) and/or electronic or a combination of mechanical (cable, linkage, hydraulic, air assisted or direct coupling) and/or electronic systems that constantly monitors and/or controls the position of the original diesel engine fuel injection pump rack.
The device works in conjunction with an ECU (Electronic Control Unit) and one, some or all of the following engine sensors. Air intake temperature, fuel pressure, fuel temperature, exhaust temperature, engine coolant temperature, engine revs per minute, camshaft position, throttle position, intake manifold pressure and lambda to control the position of the diesel rack and override the original diesel pump mechanical governor system to deliver the optimum amount of fuel for any rpm and load condition the engine can operate at.
2. From data supplied by the engine sensors the ECU calculates the correct fuel required for every engine rpm and load condition and the diesel fuel injection pump rack position controller positions the diesel pump rack accordingly to optimise fuel economy and emissions. The ECU also controls the gas injectors and diesel pump rack position and therefore the diesel fuel delivery in a dual fuel (LPG, LNG, CNG and diesel) engine.
3. The Diesel Fuel Injection Pump rack Position Controller can either be mounted directly to the original diesel Injection pump or mounted in any convenient position and connected to the diesel pump rack by cable or linkage (as shown in the attached drawings numbers The Diesel Fuel Injection Pump Rack Position Controller overrides the original diesel Injection pump governor that would control the distribution rack position in a normal diesel fuel injection pump.
4. The invention is a means of electronically monitoring and/or controlling the diesel fuel pump rack piston with a direct link to the diesel fuel injection pump rack which is located inside the diesel fuel pump. This will electronically vary the amount of fuel delivered to the engine dependant upon rpm and load conditions. The normal method would be for the diesel fuel pump rack to be positioned via the throttle cable or linkage and the governor assembly within the diesel fuel pump.
The device is a cylindrical shaped electronically controlled linear motor with a moveable steel shaft fitted inside the length of the motor. The position of the shaft can be varied by altering the electrical current to the electrical circuit in the main body of the electronic motor. Included in the electrical circuit of the device is a position sensor that is used to register the position of the shaft.
6. The Diesel Fuel Injection Pump Rack Position Controller can be used on diesel engines with any number of cylinders.
Page 3 Explanations of drawings and functions: Drawing number PD-001 (Figure 1) Original Diesel Fuel Injector Pump showing the original governor system and connection between the throttle lever and the diesel distribution rack. The governor is a mechanical device made up with levers, springs and weights that are mounted on a rotating shaft in the pump. As the speed of the engine increases so does the diesel injection pump shaft speed increase and centrifugal force moves the governor weights which are connected via linkage to the diesel distribution rack.
The position of the diesel distribution pump rack determines how much diesel fuel is delivered to the engine.
The diesel injection pump distribution rack position is not actually controlled by the throttle lever but by a combination of the throttle lever position, engine speed and the governor position.
Drawing number PD-002 (Figure 2) The same as drawing number PD-001 (Figure 1) except the original rack governor position is different (because the centrifugal weights have been moved as a function of increased revs of the engine) and accordingly the diesel distribution rack position is also different and therefore delivering a different amount of fuel to the engine.
Note: The position of the throttle lever remains unchanged from drawing number PD-001 (Figure This shows the position of the distribution rack is controlled by a combination of the governor (which is influenced by engine rpm) and the throttle lever.
Drawing number PD-003 (Figure 3) Illustrates an alternative method of mounting connecting the Diesel Fuel Injector Pump Rack Position Controller to the diesel pump and diesel distribution rack. This method shows the original diesel governor device has been removed and a direct linkage to connect the throttle lever to the distribution rack fitted, with the Diesel Fuel Injector Pump Rack Position Controller connected to the throttle lever the diesel distribution rack and the Diesel Fuel Injector Pump Rack Position Controller are directly linked together. When the throttle lever position is changed the diesel distribution rack position is also directly changed.
Drawing number PD-004 (Figure 4) Illustrates an alternative method of mounting connecting the Diesel Fuel Injector Pump Rack Position Controller to the diesel pump and diesel distribution rack. This method shows the original diesel governor device remains and the Diesel Fuel Injector Pump Rack Position Controller is connected using linkage direct to the end on diesel distribution rack. The Diesel Fuel Injector Pump Rack Position Controller overrides the original diesel governor directly controls the diesel distribution position.
Page 4 Drawing number PD-005 (Figure Illustrates an alternative method of mounting/ connecting the Diesel Fuel Injector Pump Rack Position Controller to the diesel pump and distribution rack. This method shows the Diesel Fuel Injector Pump Rack Position Controller connected direct to the diesel distribution rack.
The Diesel Fuel Injector Pump Rack Position Controller overrides the original diesel governor and directly controls the diesel distribution rack position.
Drawing number PD-006 (Figure 6) Illustrates an alternative method of mounting connecting the Diesel Fuel Injector Pump Rack Position Controller to the diesel pump and distribution rack. This method shows the Diesel Fuel Injector Pump Rack Position Controller connected by linkage to the diesel distribution rack. The Diesel Fuel Injector Pump Rack Position Controller overrides the original diesel governor and directly controls the diesel distribution rack position.
Drawing number PD-007 (Figure 7) Illustrates an alternative method of mounting/connecting the Diesel Fuel Injector Pump Rack Position Controller to the diesel pump and distribution rack. This method shows the Diesel Fuel Injector Pump Rack Position Controller connected by cable to the diesel distribution rack. The Diesel Fuel Injector Pump Rack Position Controller overrides the original diesel governor and directly controls the diesel distribution rack position.

Claims (6)

1. By electronically controlling the Diesel fuel injection pump Rack Position in the diesel fuel pump and being able to vary the rack position the device can be used as a diesel flow limiting device.
2. By using the Diesel Fuel Injection Pump Rack Position Controller to electronically control the diesel rack position it is possible to add LPG, LNG or CNG to the engine through an additional set of injectors operated sequentially to create a very low emission dual fuel gas and diesel engine.
3. By using the Diesel Fuel Injection Pump Rack Position Controller in conjunction with the ECU and sensors. It is possible to convert an engine with a mechanical type of diesel injection pump to either an electronically controlled fuel delivery system or to convert it to a dual fuel engine with the benefit of both improved fuel consumption and improved emissions.
4. The Diesel Fuel Injection Pump Rack Position Controller can be used on either a dedicated diesel engine or a dual fuels diesel and dedicated gas engine. The Diesel Fuel Injection Pump Rack Position Controller can be used to electronically position the diesel Injection pump rack.
This will prevent over fuelling of the engine during acceleration and after gear changes therefore decreasing the subsequent puff of black smoke emitted from a diesel engine therefore reducing emissions and decreasing fuel consumption.
6. The Diesel Fuel Injection Pump Rack Position Controller controls the position of the diesel pump distribution rack (in conjunction with the ECU) in a direct relationship to throttle position and therefore continuously optimises fuel delivery for every engine rpm and load condition.
