  • Direct injection diesel engines
    Patent number: 8770168
    Abstract: A piston for a four valve direct injection diesel engine defines a combustion chamber comprising a recess (10) in the piston crown, which is rotationally symmetrical about the axis of the piston in axial cross-section and is defined by a base and a side wall. A generally conical projection (5) is upstanding from the base. The recess (10) includes a lower toroidal portion (8) and an upper portion (10), whose diameter progressively increases towards the piston crown. The upper and lower portions of the recess are separated by an annular, arcuate lip (12) extending into the recess.
    Type: Grant

  • Internal combustion engine provided with a decompression-type braking device and with a turbocharger having a variable geometry turbine
    Patent number: 6619040
    Abstract: An internal combustion engine provided with a decompression-type braking system and with a turbocharger having a variable geometry turbine, in which the effective flow section of the gases entering the turbine under the maximum braking power condition is maintained at least equal to a safety limit value calculated on the basis of geometrical characteristics and of limit values of operating parameters of the engine and of the turbocharger for the purpose of achieving the maximum braking power compatible with the safety of the engine and of the turbocharger.
