Definitions

  • the present invention relates to a supercharged internal combustion engine comprising an exhaust driven turbo- compresscr and a compressor mechanically driven bv the engine, the pressure sice of said compressor being connected 5 to the suction side of said turbo-compressor, and means for suspending the effect of the mechanical compressor on the* supercharging of the engine.
  • a pair of valves are arranged which are switched over when sufficient charge pressure can be achieved with the turbo-compressor alone so that the pressure side of the mechanical compressor is connected to a charge air cooler for the turbo-compressor at the same time as the turbo-compressor's suction side is reconnected from the pressure side of the mechanical compressor directly to an air intake.
  • the purpose of the present invention is in general, starting from the above mentioned known series coupling of a
  • valve means being disposed to be kept closed as long as the amount of air delivered by the mechanical compressor is greater than the air requirement of the turbo-compressor, and to open when the air requirement of the latter exceeds the
  • said valve means can be formed by a simple mechanical non ⁇ return valve, which automatically opens towards the suction side of the turbo-compressor when the pressure on said side drops below the pressure on the air intake side of said valve.
  • the valve can cooperate with control means which disengages a clutch arranged between the engine and the mechanical compressor when the .valve opens.
  • Figs 1 and 2 show schematically two diesel engines representing two different embodiments of the compressor system.
  • Fig 1, 1 designates an internal combustion engine of diesel type, 2 the engine intake conduit and 3 its exhaust conduit.
  • a turbo-compressor consisting of a turbine portion 4 and a compressor portion 5, is connected in the
  • the intake conduit 2 is branched from a conduit 6 between an air filter 7 and the suction side of a compressor 8 mechanically driven by the engine l.
  • This can be of any known type at all, but preferably of displacement type, e.g. 20 a screw compressor, which is driven ' directly by the engine crank shaft via a V-belt transmission with the general designation 9.
  • a conduit 12 is coupled via a conduit 12 to the intake conduit 2 upstream of the turbo-compressor but downstream from a mechanical non-return belt 13, which can be of any suitable known type, e.g. a valve with a closing element in the form of a spring-biassed flap.
  • the magnetic clutch 10 When the engine 1 is at idle, the magnetic clutch 10 is disengaged and the compressor 8 is thus at rest. As the throttle is slowly opened, with accompanying slow increase in r.p.m. , the mechanical compressor 8 is engaged at a predetermined r.p.m., for example ca 1500 r.p.m. The engagement is thus dependent on r.p.m. when the throttle is 5 opened slowly and the load increases slowly. If, however, signals indicating a sharp increase in load, at an engine speed below the engagement r.p.m. , are received by the control unit 11, the mechanical compressor 8 is engaged earlier so that the required charge pressure is always 0 obtained.
  • the turbo-compressor 4,5 will assume a larger and larger proportion of the total charged pressure, and when the turbo-compressor requires more 5 air on the suction side than what the mechanical compressor is able to deliver, the non-return valve 13 will open automatically since the pressure downstream of the non-return valve 13 will then be less than the pressure on the air filter side.
  • the mechanical compressor 8, after the non- 0 return valve is opened, will have no function and in order to reduce the energy consumption of the engine and noise as well as reduce wear to the compressor 8, this should be turned off . at this stage. This can also be effected via the control unit by storing a predetermined turn-off r.p.m., for example 3.000 5 r.p.m. , in the control unit or via signals to the control unit indicating that the non-return valve is open.
  • valve 14 is in the form of an electrically operated on-off valve 14 arranged in the intake conduit 2.
  • the turning on and off of 5 the valve 14 is controlled by the control unit 11 in response to signals from a pair of pressure sensors 15 and 16, respectively, on the suction and pressure sides, respectively, of the mechanical compressor 8.
  • the control unit is thus disposed to open the valve 14 when the signals sent to the control unit by the pressure sensors 15,16 indicate that the pressure on the suction and pressure sides are equal. These signals are also used to simultaneously turn off the mechanical compressor.

Abstract

Moteur surcomprimé à combustion interne (1) muni d'un compresseur mécanique (8) et d'un turbocompresseur (4, 5) couplés en série. Le turbocompresseur est couplé en aval du compresseur mécanique. Entre la liaison (12) entre ce dernier et le côté à dépression du turbocompresseur, d'une part, et l'entrée d'air (7) dudit turbocompresseur, d'autre part, se trouve un clapet de retenue (13) qui s'ouvre en direction du turbocompresseur lorsque la quantité d'air nécessaire au turbocompresseur dépasse la capacité du compresseur mécanique.
