Definitions

  • FUMIGATION DEVICES FOR SUPERCHARGED DIESEL ENGINES Inventors: Maurice G. Brille; Yves-Marie E.
  • the present invention relates to devices for atomizing fuel into the induction manifold of supercharged Diesel engines, which are generally referred to as fumigating devices.
  • This invention is applicable more particularly to compression-ignition or Diesel engines comprising a crankcase containing engine lubricating oil circulated by an oil pump, a feed pump supplying liquid fuel to an injection pump, and a volumetric pump having its input orifice connected to a direct air supply pipe or to the delivery pipe of a turbo-compressor driven from the engine exhaust gas and having its output orifice connected to an engine air induction pipe.
  • the object of the atomization of fuel into the induction air pipe is to promote the starting of the combustions in Diesel or compression-ignition engines.
  • Fumigation devices which supply about percent of the necessary fuel by means of a carburetor disposed upstream of the air induction pipe of the engine and associated with a conventional injection system supplying the residual fuel in the proportion of about 80 percent.
  • This volumetric pump constitutes a correcting apparatus driven in a variable manner from the engine and acts now as a pressure-reducing device under high power-output conditions, now as a compressor under reduced engine load conditions, the reduction in the volumetric ratio permitting the use of very high supercharging rates.
  • Engines of this character have been described in the U.S. Pat. No. 3,595,013 by the same applicants.
  • the device according to the present invention is characterized in that the pipes supplying liquid fuels and liquid additives to the engine open into the delivery pipe upstream of the volumetric pump, this volumetric pump being of the gear type and acting jointly as a pump and as an atomizer.
  • the gear compressor constitutes a very efficient atomizer capable of producing a liquid-air mixture and a mist sufficiently homogeneous to ensure a proper distribution thereof among the various cylinders of a multicylinder engine.
  • the powerful and very efficient atomization at all engine speeds is attended by an incipient fuel oxidation promoting the ignition.
  • the device according to this invention operates under constantoutput conditions.
  • the engine operates at idling speeds simply by means of the fumigation mixture, by self-ignition, without resorting to its conventional injection system. In this manner, these engines operate at idling speeds with considerably reduced noise levels, which makes these engines as silent as gasoline engines.
  • any liquid possibly deposited at the bottom of this manifold is collected and re-injected into the suction pipe of the gear-type compressor.
  • this recovery path constitutes a bypass corresponding to a slight leakage of the compressor. Therefore, the inlet or outlet passage of this by-pass is of nearly capillary size, thus reducing the air leak to a negligible value and promoting the flow of liquid therethrough when a condensation takes place.
  • FIG. 1 illustrates diagrammatically in cross-section a supercharged Diesel or compression-ignition engine equipped with a device according to this invention
  • FIG. 2 is a longitudinal view of the same engine, as seen in the direction of the arrows IIII of FIG. 1.
  • the Diesel engine 1 is supercharged by means of a turbocompressor 2 scavenging air into the gear pump 3 driven at a variable speed from the pulley 4, through an endless belt 5 and another pulley 6.
  • the volumetric pump may be driven from the engine crankshaft via a variable-speed transmission causing the pump to produce an output to volume ratio now greater, now smaller, than the engine cylinder capacity.
  • variable-speed drive is not illustrated, since it may consist of any suitable and known arrangement such as a V-belt drive, or a hydraulic pump and motor of the barrel-cylinder type, inter alia.
  • the engine is equipped with a lubricating oil pump 7, a fuel feed pump 8 and an injection pump 9.
  • the delivery pipe 10 connects the turbo-compressor 2 to the gear pump 3 and extends through a heat exchanger 11 of which the other circuit receives water from the engine cooling system at a regulated temperature.
  • Pipes l3, l4 and 15 provided at their outlet ends with jets 16, 17 and 18 respectively, opening into said delivery pipe 10 very close to the inlet of pump 3.
  • Pipe 13 is connected directly to the fuel feed pump 8 and pipe 14 is connected to the lubricating oil pump 7.
  • Pipe 15 of very small cross-sectional passage area is connected to the lower portion 19 of the general induction manifold 20 communicating with the cylinder head through pipes 21.
  • valve 22 Inserted in pipe 13 are a valve 22 and a nonreturn valve 23.
  • valve 24 and downstream thereof a branch pipe 25 equipped with a valve 26 are inserted in pipe 14.
  • the fuel feed pump 8 delivers fuel under a pressure of about 35 psi, which in general is higher than the pressure prevailing in pipe 10, notably when the engine loads and speeds are of medium or low values.
  • the fuel flows through the jet 16 into the compressor with a certain output and is delivered in a perfectly atomized condition into the manifold 20.
  • the fuel mist just produced is distributed among the pipes 21 and facilitates the combustion by tending to reduce the ignition time.
  • the normal injection takes place simultaneously through the conventional injectors (not shown) from the injection pump 9.
  • the fuel output flowing through said jet 16 depends of course on the cross-sectional passage area thereof, and also on the pressure differential between the fuel pump 8 and pipe but not on the engine speed.
  • the proportion of fuel caused to fumigate decreases with the engine speed and even with the engine load for the higher the load, the higher the pressure in pipe 10. This is in conformity with the desired operating conditions.
  • This fumigation device not only facilitates the normal operation of the engine with gasoil, but also permits a multi-fuel operation, it being understood that the heat exchanger 1 1 is adapted to regularize the air temperature upstream of compressor 3 at a value approximating that of the engine water regulation temperature.
  • the valve 24 may be used for controlling the time periods during which it is desired to obtain this intermittent supply of additional oil mist.
  • an electrical or mechanical timing control system may be provided for operating this valve 24.
  • the same jet 17 may be used for introducing another type of oil or additive independent of the engine lubricating oil circuit, valve 24 being closed and valve 26 open in this case.
  • the pipe 15 may be used for returning to the jet 18 the liquid collected at the bottom of manifold 20.
  • a device for atomizmg a liquid fuel and at least intermittently a liquid additive into Diesel engines comprising a crankcase containing engine lubricating oil which is circulated by means of a lubricating oil pump, a fuel feed pump delivering liquid fuel to an injection pump and a volumetric pump connected through its input orifice to an air supply pipe fed by a turbo-compressor driven from the engine exhaust gas, and through its output orifice to an engine air induction pipe, the device further comprising a plurality of separate jets opening into said air supply pipe upstream of said volumetric pump, and a plurality of pipes for supplying liquid fuel and additive through said jets, said volumetric pump being a gear pump operating simultaneously as a pump and as an atomizer.
  • a device characterized in that a pipe for returning any liquid condensed and accumulated in the bottom of the engine air induction pipe opens into the air supply pipe upstream of said volumetric pump, the cross-sectional passage area of at least one of the orifices of said return pipe being such that it provides a liquid output corresponding substantially to the maximum quantity of liquid likely to condense on the walls of said air induction pipe.
  • a device wherein one of said pipes is for supplying additive liquid and is connected to the lubricating oil pump, a first valve being interposed in said oil supply pipe.
  • valve is of intermittent and pre-adjusted opening type.
  • a device wherein a pipe for supplying an additional liquid additive is connected through a second valve to the oil supply pipe downstream of the first valve.
  • a device wherein one of said supply pipes is connected to a duct connecting the fuel feed pump to the injection pump, a stop valve and non-return valve are disposed in said pipe, said non-return valve being upstream of said stop valve, and the jet of said supply pipe has a specific cross-sectional passage area for providing a constant liquid output from said jet.
