Definitions

  • the method includes directing the vaporised fuel into the main combustion chamber in such a manner that it creates swirling of said vaporised fuel within the main chamber.
  • the main combustion chamber 12 is formed in the crown 18 of an engine piston 20 mounted for reciprocal movement within a cylinder 22 formed in an engine block 24.
  • the cylinder. 22 is capped by a cylinder head 26, an inner surface 28 of which defines the upper limit of the main combustion chamber 12.
  • Heating elements 38 are housed within the chamber wall 14 to increase the vaporising chamber temperature, when required.
  • a small amount of fuel a pilot charge
  • the main fuel charge is then injected into the resulting high temperature turbulent zone in the vaporising chamber.
  • the main fuel charge is vaporised and at least the majority of it passes through the apertures 16 in the wall 14 to mix with hot compressed air in the main combustion chamber 12 for completion of the burning process. Thus, diffusion burning of the fuel is promoted.

Abstract

Moteur à combustion interne qui est doté d'une chambre (10) de vaporisation de carburant séparée d'une chambre (12) principale de combustion, mais adjacente à ladite chambre. La paroi (14) de la chambre (10) de vaporisation possède au moins une ouverture (16) permettant à du carburant partiellement vaporisé de pénétrer dans la chambre principale (12) de combustion. Du carburant est introduit (injecté) dans la chambre (10) de vaporisation et de l'énergie thermique résiduelle ou ajoutée vaporise partiellement le carburant injecté. Ce procédé favorise la combustion, réduisant ainsi les substances d'échappement non désirées.
