Definitions

  • the present invention relates to a diesel piston engine of a new type, at least one cylinder of which can be used at will, sometimes as an engine, sometimes as an air compressor.
  • a device is provided more particularly, although not exclusively, for the diesel engine of a vehicle such as a truck or a bus.
  • the object of the present invention is to avoid these drawbacks by producing a diesel piston engine in which at least one cylinder is capable of operating, as desired and reversibly, either as an engine or as a compressor with sufficient efficiency to allow d '' supply compressed air storage bottles.
  • At least one intake valve of an engine or compressor cylinder is connected by hydraulic intake means to one of the cams of the engine timing camshaft to open this intake valve during all or part of what would be the expansion time if this cylinder operated as an engine, while the starting of these hydraulic intake means is engaged by the switching means when they are in the position so that the targeted cylinder functions as a compressor.
  • Fig. 1 is an axial section view schematically showing two cylinders of the same diesel engine according to the invention.
  • Fig. 2 is a diagram illustrating several operating diagrams of the cycle in motor and in compressor.
  • An oil pump 16 takes lubricating oil from a storage case 17, to supply the main lubricating pipe 18 of the engine.
  • two hydraulic pipes 19 and 20 are connected in parallel to the pipe 18, each provided with a starting throttle 21, 22.
  • a return spring 34 keeps the valve 33 closed as long as the hydraulic pressure in the receiving cylinder 31 does not prevail over the setting of the spring 34.
  • the cylinder head 9 Downstream of the valve 33, the cylinder head 9 defines a discharge pipe 35 on which is interposed a non-return valve 36 that a pipe 37 connects to two tanks 38 and 39 for the storage of compressed air.
  • a pressure detector 40 is sensitive to the level of the air pressure in the tanks 38 and 39. It cooperates with a deceleration detector 41, which is sensitive to the intensity of the deceleration of the vehicle, to control a trip device 42, which opens or closes the valve 24 and another valve 43 on which it is coupled.
  • a non-return valve 54.55 is provided on each of the pipes 19.20.
  • a dispenser 12 comprises a valve 58 held in its seat by the spring 72 and by the pressure of the fuel in the injection pipe 1 1,14; in the open position, this valve diverts the fuel through the line 13 to the tank 73.
  • This valve 58 is integral with the central part of a flexible and waterproof membrane 7 4 subjected to the pressure of the pipe 56.
  • the pipe 20 receives in parallel a pipe 56, which opens into the distributor 12 to actuate the piston 57 of its distributor valve 58.
  • This separation of the intake valve 7 corresponds to a preferred, but not compulsory, embodiment of the invention.
  • Fig. 2 shows the laws and the order of actuation of the various elements according to the invention.
  • the degrees of angle of rotation of the engine crankshaft were plotted on the abscissa. Diesel.
  • Curve 59 illustrates the movement of the main piston 68 of cylinder 1, which moves alternately between top dead centers such as 60, 61, 62 and bottom dead centers such as 63, 64, 65.
  • Curve 66 illustrates the known opening and closing movement of the exhaust valve (not shown) of cylinder 1.
  • the curve 67 illustrates the opening and closing movement of the intake valve 7.
  • the detachment of the intake valve 7 takes place according to the arc of curve 69, after the top dead center 61 where the injection should have taken place.
  • the curve 70 illustrates the movement of the additional valve 33 which opens at the end of compression, before the top dead center 61.
  • curve 71 the evolution of the compressed air pressure inside the cylinder 1.
  • the cylinder 1 replenishes compressed air during the time separating the dead centers 63 and 61, that is to say once every two turns of the crankshaft, during a phase of energy recovery and deceleration of the vehicle.
