Definitions

  • troposphere ozone is an extremely reactive and dangerous air contaminant, condemned by the National Academy of Science and other experts, and now regulated to a limit of 0.08 part-per-million in air as an official interpretation of the Clean Air Act Amendments of 1999. At this time most states are in non-attainment, and are straining their resources to be compliant, as evident from their State Implementation Plans (SIPS), submitted periodically to the U.S.EPA. Given this background, it will be seen that the minimization of unburned fuel (VOCs) is a very important element in tropospheric ozone reduction. It will be welcomed by both regulators and environmentalists as one of the many that will ultimately lead to cleaner air.
  • VOCs unburned fuel
  • Valve tulips Carbonaceous build-ups on valve seats (valve tulips) cause loss of compression and an interference with optimum air-to-fuel ratios. Deposits in combustion chambers act to reduce the tension in compression rings. In turn, this reduces compressions, as well as engine power. Because of unbalanced piston compressions, engine vibrations will increase, causing excessive engine wear and reduced fuel mileage, plus even more emissions of unburned hydrocarbon fuel. Deposits on spark plugs also interfere with optimum fuel bum, due to the changing of their dynamic kilovoltage (KV) and millisecond pulse width. Carbonaceous deposits in the EGR valve are the cause of engine surging, rough engine syndrome and giving a check engine light.
  • KV dynamic kilovoltage
  • CSPIT Cold Spark Plug Immersion Test
  • Our invention can be employed to provide a series of synergistic liquid mixtures, each capable of dispersing and dissolving modem baked-on carbonaceous deposits from the surface of the upper cylinder area of internal combustion engines, including the spark plugs and all the other component surfaces in this enclosure. Maintaining surface cleanliness is a major element in sustaining maximum operating efficiency of these engines.
  • polar protic and dipolar aprotic solvents either independently or in blends having a dielectric constant above 25 or more, can be synergized by raising the pH value to 11 or above (at 25 deg. C.). ( See Fig. 10 , Graph No. 3 ) .
  • Methyl Formamide with a uniquely high dielectric constant in excess of 200, is unusually effective.
  • Hydrazine and certain close derivatives
  • a dielectric constant of about 53 and a pH valve of over 13 at 25 deg. C.
  • concentrated aqueous Ammonium Hydroxide Solutions typically with 28.6% ammonia content
  • having a dielectric constant of about 61 and a pH valve of over 13 25 deg. C.
  • Our invention provides three distinct techniques for cleaning the component of the upper cylinder area of internal combustion engines. These are:
  • aerosols with the desired synergistic composition and pre-determined delivery rate would be made available, together with the appropriate connector of plastic tubing and adapters.
  • Each aerosol dispenser could be sized to provide maintenance for a multiplicity of internal combustion engines.
  • Figs. 1-3 Illustrate an aerosol dispenser and adaptors for use with the invention
  • Figs. 4-7 Illustrate various means for delivering the chemical composition of the invention to approximate areas of an engine
  • Figs. 8-10 Illustrate graphs demonstrating effective use of the invention.
  • Our invention provides specific compositions of matter ideal for dispersing and dissolving dense layers of heavy, baked-on carbonaceous deposits that form on surfaces within the upper internal combustion engine chambers; wherein a polar protic or dipolar aprotic solvent is synergized with a primary, secondary or tertiary amine, up to a pH valve of a least 11 (at 25 deg. C.).
  • a polar protic or dipolar aprotic solvent is synergized with a primary, secondary or tertiary amine, up to a pH valve of a least 11 (at 25 deg. C.).
  • a polar protic or dipolar aprotic solvent is synergized with a primary, secondary or tertiary amine, up to a pH valve of a least 11 (at 25 deg. C.).
  • a polar protic or dipolar aprotic solvent is synergized with a primary, secondary or tertiary amine, up to a pH valve of
  • the synergistic cleaning compositions should have a pH of 13 (at 25 deg. C.) or higher, and a dielectric constant of 35 or higher. This high level of cleaning efficiency is required because of limits imposed on engine cleaning time by OE shops, which is usually in the range of 5 to 10 minutes.
  • the optimized upper engine aerosol formula for gasoline engines has a pH value of about 13.6 (25 deg. C.) and a dielectric constant of 32.01. When this optimized composition is blended in the order listed, (with moderate agitation) the batch temperature increases by approximately 16% after adding De-Ionized Water to N-Methylformamide and then increases another 16% when the primary alkylamine is added.
  • the blend tank should be tightly closed and maintained with slow agitation until the batch temperature returns to room temperature.
  • the blending room should be well ventilated.
  • the aerosol is made by a two stage fill. First filling the concentrate into the aerosol unit and then pressure filling with the propellant and mechanically crimping the valve onto the aerosol unit. When this composition is sprayed into a test jar, using the appropriate adapter, about 40% of the product is gassed-off, due to propellant evaporation. The remaining fluid, approximately 50 ml of liquid product will typically have a temperature of about -4 deg. F. (-20 deg. C.). (50% or more of the propellant evaporates when sprayed into the plenum of a warmed-up engine, which raises the dielectric constant of the fluid to 50 plus).
  • the plug To conduct the spark plug cleaning test, the plug must be lowered very slowly into the very cold liquid. This will cause some boiling, but will avoid an excessive boil-out and loss of some liquid. Use a stopwatch or other timer and wait for two (2) minutes; then lift out the plug. The test solution is then slowly poured into the standard 250 ml cylinder and brought to 250 ml with De-ionized Water, taking care not to have an excessive final boil-off of propellant. Stir until uniform. Transfer some of this solution into the Orbeco-Hellige glass tube and insert into the colorimetric test unit. Under these very cold conditions the scale reading will typically show 3.4, indicating that about 35% of the baked-on carbonaceous deposit has been dispersed and dissolved.
  • the optimized formula for preventative maintenance is packaged as a 7.5 ounce (212 grams) filled in an aerosol container, which is then attached to the upper engine plenum by the use of a special adapter ( Fig. 1 ). It is important to assure that the product is delivered into the plenum in form of a mist of finely divided particles. To do this we have selected two capillary type extension tubes; one with a 0.033" (0.84 mm) and one with a 0.042" (1.07 mm) inside diameter. [See Fig. 4 , Product part No. 610000 (0.042 I.D.) and Product Part No. 640000 (0.033 I.D.)].
  • capillary tubes are inserted into a Locking Actuator Cap.
  • the O.D. of the capillary tube is 0.102" (02.59 mm) and the I.D. of the tube housing which protrudes from the Locking Actuator Cap is 0.107" (2.718 mm) and narrows to 0.100" (2.54 mm) at the center of the Actuator. [See Fig. 5 A ].
  • the capillary tubes are pressed firmly toward the center of the Actuator and extend out ward 30" to 40", (this long adapter lets the user place the aerosol unit away from the hot vehicle engine during the cleaning process).
  • a clear PVC tube is placed over the capillary tube for protection and pressed fitted over the protruding tube-housing on the Actuator and then a multi-adapter is inserted into the other end of the clear PVC tube, so this can be attach to the air intake vehicle plenum, (See Fig. 6 , clear PVC tube.) and (See Fig. 7 , multi-adapter for the vehicle plenum).
  • the capillary tube will protrude approximately one inch (1") out of the multi-adapter, so that the synergistic spray mist goes directly into the plenum.
  • Using the 0.033" (0.84 mm) capillary tube adapter gives a product delivery rate of about 0.50 grams per second and will last approximately seven minutes.
  • the 0.042 (1.07 mm) capillary tube adapter delivers about 0.90 gram of product per second and will empty the aerosol unit in approximately four (4) minutes. The lower delivery rate works best for small gasoline and diesel engines.
  • a preferred use of this product is to attach the over-cap actuator onto the aerosol valve stem and mounting cup, and then position the other end of the eductor tube, protruding through the variable diameter plenum adapter, into the upper engine plenum. Then slowly depress the actuator pad until a mechanical feature locks the valve in an "open" position. The aerosol unit will then spray until it is empty.
  • the discharge rate is normally four (4) to seven (7) minutes depending on the size of the capillary I.D. selected. Since there is no operator present, in the event that the engine should stall, the aerosol will continue to spray until empty.
  • This controlled spray mist will not cause any harm to the stalled engine, because this capillary adapter prevents the possibility of discharging the synergistic mixture as a heavy wet spray or liquid stream that would tend to run down the plenum wall to the closest intake runner. It would then accumulate behind a single intake valve, or if that valve was open, it would then leak down upon the top of the piston. If these things happen, when the operator attempts to start the engine, there will be the risk of hydraulically locking it, cracking the top of the piston or bending a piston rod, thus severely damaging or even destroying the engine.
  • the optimized Diesel mist formula ( Table Four), Formula 526 also requires the use of this same adapter, which will deliver a finely particled mist into the center of the intake air flow, after the air filter has been removed, and when the diesel engine is at idle speed.
  • a different formula (Table Four),Formula 525 can utilize this same adapter without the capillary inner tube and without a lock-down aerosol valve actuator. (This is illustrated in Fig. 2 ).
  • the adapter for this assembly is designed to deliver a heavy, wet, residual spray into the plenum of a gasoline engine and adjust the engine speed to about 1500 rpm. The mechanic will then shake the aerosol dispenser, using a spray and release technique until the aerosol is empty.
  • This spray technique requires the mechanic to fully actuate the aerosol dispenser for about 5 to 10 seconds, this will produce a flooding action in the upper engine which will cause the speed to decrease to about 500 rpm. The mechanic will then shut off the spray and this will allow the engine to recover its original speed of about 1500 rpm. The procedure is repeated, until the aerosol is less than about 5% full. At this point, the aerosol should be actuated until the engine stalls, after which the dispenser can be sprayed for a few more seconds until the can is empty.
  • the mechanic will then let the engine “soak” for ten (10) to fifteen (15) minutes. Then he should crank the engine very slowly until it has made one complete revolution, after which regular cranking can be initiated until the engine starts.
  • the engine is brought to about 3000 rpm, then snapped to about 5000 rpm briefly, to blow out any loose carbonaceous fragments.
  • the vehicle should be driven for 3 to 5 miles, to fully exhaust the combustion chambers and catalytic converter.
  • Formula 525 can be effectively used to "soak" cylinders, to clean entire combustion chambers, cylinder domes, piston heads and to release compression rings that have been frozen into place by hard carbonaceous depositions.
  • This cleaning technique requires the use of a unique adapter 360 degree tip (illustrated in Fig. 3 ), attached to a standard plenum adapter, by replacing the multi-adapter tip with the 360 degree brass spray tip.
