Definitions

  • stoichiometricity is a condition where the amount of oxidant required to completely burn a given amount of fuel is supplied in a homogeneous mixture resulting in optimally correct combustion with no residues remaining from incomplete or inefficient oxidation.
  • the fuel should be completely vaporized, intermixed with air, and homogenized prior to ignition for proper oxidation.
  • Non-vaporized fuel droplets do not ignite or combust completely in conventional internal and external combustion engines, which degrades fuel efficiency and increases engine out pollution.
  • the valve may include a poppet valve.
  • the poppet valve may be biased into a closed position.
  • the controller may open the valve during a compression cycle during the engine start cycle.
  • the controller may operate to control flow of compressed air stored in the accumulator to a fuel delivery system.
  • the accumulator may include a storage tank.
  • the accumulator may hold a volume of compressed air sufficient for at least one engine firing sequence.
  • the valve may include a poppet valve opening in the cylinder that is arranged outward opening.
  • the charging system may include a solenoid configured to move the valve between opened and closed positions.
  • Another aspect of the present disclosure relates to a method of scavenging compressed air from an engine cylinder.
  • the method includes providing a valve and an accumulator, wherein the valve provides access to the engine cylinder and the accumulator is coupled in flow communication with the valve.
  • the method also includes opening the valve during an engine compression stroke, collecting compressed air from the cylinder into the accumulator while the valve is opened, and storing the compressed air in the accumulator for use in a fuel delivery system.
  • the method may also include closing the valve upon reaching a predetermined pressure condition in the accumulator.
  • the method may include closing the valve upon completion of the engine compression stroke.
  • the valve may include a valve opening directly into the cylinder, a valve seat positioned within the cylinder, and a poppet valve movable into and out of sealing contact with the valve seat.
  • the method may include biasing the valve into a closed position.
  • FIGS. 5A and 5B are cross-sectional views of an example valve assembly in accordance with the present disclosure arranged in closed and open positions, respectively.
  • FIG. 6 shows a flow diagram of an example functional strategy in accordance with the present disclosure.
  • the charge valve assembly 12 includes a valve member 40, a valve seat 42, a valve opening 44, a solenoid 46, and a biasing member 48.
  • the valve member 40 includes a stem 50 and a head 52. The head 52 seals against the valve seat 42 when the charge valve assembly 12 is in a closed position as shown in FIG. 5A.
  • Operating the solenoid 46 moves the head 52 away from the valve seat 42 to permit flow of gases (e.g. , air) through the valve opening 44 as shown in FIG. 5B.
  • the biasing member 48 biases the head 52 into the closed position of FIG. 5A.
  • the compressor 18 may be a mechanically driven or electric compressor.
  • a mechanically driven compressor 18 is typically operable after the engine 28 has started and is powered by engine 28.
  • An electric compressor may operate using power generated by engine 28 or may draw power from a different power source such as batteries that are independent of engine operation.
  • Using a mechanically driven compressor 18 may provide a low cost, low weight, simple option for providing the minimum requirements for compressed air for the fuel delivery device 26.
  • FIG. 3 shows an air charging system 200 in which the accumulator 14 is integrated as a portion or a component of engine 28.
  • the accumulator 14 is integrated as a portion or a component of engine 28.
  • other features or components of air charging system 200 may be integrated into engine 28 or combined with each other to provide, for example, a more compact, less complex system having fewer parts.
  • the air charging system 300 may further, or alternatively, include an electric compressor 332 that may be used to generate compressed air using battery power prior to the engine starting to charge the accumulator, or after the engine is started as an alternative source of compressed air if the compressor 318 or first and second charge valve assemblies 312A, 312B are not operating properly.
  • an electric compressor 332 may be used to generate compressed air using battery power prior to the engine starting to charge the accumulator, or after the engine is started as an alternative source of compressed air if the compressor 318 or first and second charge valve assemblies 312A, 312B are not operating properly.
  • One advantage associated with using the air charging systems disclosed herein is facilitating engine starting using the engine as an air pump during engine cranking, thereby eliminating the need for a separately powered air source during start up of the engine.
  • Another potential advantage is mitigating the risks associated with attempting to store compressed air for use by a fuel delivery device during start up of an engine. Dissipation of stored air may result from permeability of the storage device or leaks in the system that may occur when the engine is not running. Dissipation of the stored air charge would other inhibit operation of a dual fluids fuel delivery device.
  • the air charging systems disclosed herein may avoid reliance upon stored compressed air by collecting a volume of compressed air while cranking the engine during or just before starting.
  • a still further potential advantage relates to the added functionality provided by the air charging system with relatively little or no increased reciprocating mass, parasitic load or inertia.
