Definitions

  • the present finding regards a system suitable for allowing the ignition of an internal combustion engine through compressed air.
  • a suitable device which makes them rotate at a sufficient speed, so that the carburation or the injection takes place in a sufficiently regular manner to allow the ignition of the engines themselves.
  • the life-cycle of a normal lead-acid battery for starting up automobile engines is about 3-4 years.
  • such a storage battery fundamentally consists of materials which are toxic-poisonous (lead), as well corrosive (sulphuric acid), which determine a very high environmental cost.
  • lead-acid battery Another disadvantage of the lead-acid battery consists of its substantial weight, which goes against the requirements of vehicle designers, who try in all possible ways to lighten the overall mass of the vehicles themselves, to reduce the specific fuel consumption and therefore atmospheric pollution. Moreover, such batteries are never completely watertight (both with free acid technology, and with this technology combined with valve regulation); there is therefore the possibility that, particularly in the case of overturning of the vehicle, the corrosive sulphuric acid can spill out from the battery, causing corrosion by contact and environmental pollution.
  • Another disadvantage of the lead-acid battery consists of the possibility of exploding in the case of internal constructive defects.
  • the purpose of the present invention is that of foreseeing a compressed air starter system for vehicles with internal combustion engines, which is also capable of operating without a battery, which allows the drawbacks described above to be avoided.
  • FIG. II a schematic view of the reversible group which functions as a compressor and as an engine/starter, respectively, used in the system according to the finding is illustrated.
  • Such an element 2 with a starter function, locks through a pinion 4 to the sprocket 5 of the flywheel of the engine; the pinion 4 is moved by an air piston 6 controlled by a pneumatic valve 7; when the engine is started up the valves 3 and 7 deactivate and the pinion 4 unlocks from the sprocket 5 and the element 2, which functions as a starter, is intended to shut down.
  • the pinion 4 locks to a rotation reducer/inverter 8, which is connected to the drive shaft through a clutch 9 and begins functioning as a compressor inverting the motion to pump the compressed air into the tank.
  • a pressure limiting valve 10 is foreseen which avoids the formation of an overpressure in the tank, as well as energy wastage by the compressor.
  • the function of supplying the on-board services is carried out by a small specialised battery of the watertight type, for example of the Nickel-Metal-Hydrate type or of the Lithium Ions type (this type of battery is already used for some time in the field of mobile phones, as well as for supplying camcorders and the like).
  • a small specialised battery of the watertight type for example of the Nickel-Metal-Hydrate type or of the Lithium Ions type (this type of battery is already used for some time in the field of mobile phones, as well as for supplying camcorders and the like).
  • Such a small battery 11 is charged by a small alternator 12.
  • This specialised battery which is made independent from the engine starter system allows the entire electrical unit of the vehicle to be redesigned at a substantially greater voltage than the usual 12 Volts (for example 24 or 48 Volts).
  • the Lithium Ions battery is small in size, light, watertight and much more environmentally friendly, since it contains absolutely no toxic-poisonous materials.
  • valve 3 is opened which connects the compressed air tank to the starter/compressor element 2, which in fact replaces the electric starter.
  • the element 2 pumps air into the tank through the aforementioned valve itself, actually refilling the air tank, until it reaches a maximum pressure level, in correspondence with which the pressure limiting valve 10 closes, preventing the further filling of the tank and thus reducing the stress of the air/compressor engine which rotates idle, without taking energy away from the internal combustion engine.
  • the size of the tank and the operation of the valve must guarantee an amount of air such as to be able to operate, with the vehicle shut down, more than one ignition, without discharging completely.
  • the tank can be realised with a particular shape, so as to also satisfy a second function, for example linked to the passive safety of the vehicle.
  • the tank in a racing car or off-road car can have the shape of a tubular frame of the roll-bar type.
  • the tank can have the shape of a front or rear bumper, according to the type of traction of the vehicle.
  • the tank of compressed air is capable of carrying out the following functions:
  • element 2 capable of functioning as a compressor (fig. 2), when it turns in one direction, and as an air engine/starter (fig. 3), when it turns in the opposite direction, in a preferential embodiment it is based upon the operating principle of the rotational volumetric compressor which is self-lubricated thanks to the presence of graphite blades.
  • the rotor has three or more blades 15 which protrude radially and adhere to the stator biased by opposite radial springs 16.
  • stator On the stator two pipes 17 and 18 are formed which function, alternatively, as an air intake and output pipe, respectively.
