Definitions

  • the present invention relates to a cleaning and conditioning system. More particularly, the cleaning and conditioning system is intended for use with combustion engines burning liquid hydrocarbon fuels and utilising lubrication systems.
  • the cleaning and conditioning system of the present invention has as one object thereof to overcome substantially the above problems associated with the prior art, or to at least provide a useful alternative thereto.
  • a cleaning and conditioning system for a combustion engine characterised by the method steps of cleaning or purging a fuel delivery system of the engine and of cleaning the lubrication system of the engine.
  • the system further comprises the cleaning of any fuel tanks feeding the fuel delivery system.
  • an oil conditioner is added to the oil fed to the engine's lubrication system.
  • the purge or cleaning of the fuel delivery system is preferably achieved by running a purge fluid through the fuel delivery system whilst the engine is running.
  • the cleaning of the lubrication system is achieved by running an oil product through the engine whilst the engine is running.
  • This lubrication system cleaning step preferably comprises the staged filtering of the dialysis fluid.
  • the cleaning of the fuel delivery system and the lubrication system is achieved, at least in part, simultaneously.
  • Figure 1 is a schematic representation of the cleaning and conditioning system of the present invention shown in relation to an engine and fuel tank.
  • FIG. 1 there is shown a cleaning and conditioning system 10 for a combustion engine 12. Associated with the engine 12 is a fuel tank 14. A fuel line 16 is provided between the fuel tank 14 and a fuel injection system 18 associated with the engine 12. A fuel pump 20 is further provided in the fuel line 16.
  • a fuel tank treatment step 22 is shown in association with the fuel tank 14.
  • a fuel system purge step 24 is shown to feed a purge fluid into the fuel line 16 by way of line 26.
  • the purge fluid line 26 feeds into the fuel line 16 at a point "upstream" of the fuel pump 20, as is clearly shown in Figure 1.
  • a line 28 is provided extending from a fuel recirculation outlet of the engine 12 returning purge fluid to the purge step 24.
  • the lubrication system of the engine 12 is cleaned using an engine lubrication dialysis step 30.
  • the dialysis step 30 comprises a dialysis fluid being fed by a line 32 into the lubrication system of the engine 12 by way of the oil filler cap, whilst a line 34 returns dialysis fluid from the engine 12, by way of the sump drain plug, to the dialysis step 30.
  • the fuel tank treatment step 22 comprises the use of an apparatus in which is provided each of a pump, a water trap and a filter means.
  • a line 36 is used to transfer fuel from the apparatus 10 to the fuel tank 14.
  • the fuel is cycled through the fuel tank 14 and returned to the fuel tank cleaning apparatus by line 38. This step removes water and particulate materials from the fuel tank 14.
  • the purge step 24 acts to clean the fuel delivery system to the engine 12.
  • the fuel delivery system comprises at least a portion of the fuel line 16, the fuel pump 20, the fuel injection system 18 and the fuel return line.
  • the fuel delivery system may further comprise a water-fuel separator and a fuel filter in known manner.
  • the purge fluid is applied whilst the engine 12 is running.
  • the purge fluid acts to dissolve gums, lacquers, varnishes, wax and carbon which may have been deposited in various parts of the fuel delivery system and engine 12, including fuel lines, the fuel pump, fuel rails, fuel injectors, valves, pistons and cylinder walls.
  • the purge fluid comprises a mixture of fuel and a hydrocarbon based fuel conditioner.
  • the mix of fuel to conditioner is variable so that at start-up the ratio of fuel to conditioner is high. As the engine 12 warms up the ratio can be decreased to increase the cleaning action of the purge fluid.
  • the dialysis fluid of the dialysis step 30 utilises two distinct dialysis fluids in turn.
  • the first fluid is a kinetic flushing oil and the second fluid is a static stabilising oil.
  • These dialysis fluids are respectively used in turn and are fed through line 32 into the lubrication system of the engine 12.
  • the dialysis fluids are pumped into the various parts of the engine 12 that are typically lubricated by engine oil, including the timing gear, crank shaft, crank journal, crank pin, cylinder bore, piston ring, piston pin, rocker arm shaft, rocker arm, cam shaft, bell stems and all internal galleries, after which the dialysis fluids collect in the oil pan or sump, from which it is returned via line 34 to the dialysis step 30.
  • the kinetic flushing oil is used for cleaning of the engine components whilst the static stabilising oil is used for removal of the kinetic flushing oil.
  • the dialysis step 30 utilises dialysis apparatus comprising a filter bank and a pump.
  • the pump typically moves about 9 to 12 litres per minute and forces the dialysis fluid through a series of three staged filters, the first filter passing 25 ⁇ m, the second filter passing 10 ⁇ m and the third filter passing 5 ⁇ m.
  • the line 32 passes the dialysis fluids to the oil filler cap in the rocker cover of the engine 12.
  • the dialysis step is run for about 30 minutes, as is the purge step 24. It is envisaged that the dialysis step 30 may be run in as little time as about 15 minutes. The inventors have determined that no significant benefit is obtained running the dialysis step 30 beyond 30 minutes.
  • an oil conditioner may be used in the lubrication system of the engine 12 to further ensure the benefits of the cleaning and conditioning system of the present invention are maintained.
