Embodiment Construction

[0052] Figure 1 to Figure 6 The ignition insert with active pre-chamber 1 according to the invention, various details of its components, its alternative embodiments and its accessories are shown.

[0053] The ignition insert with active pre-chamber 1 is provided in particular for an internal combustion engine 2 comprising a cylinder head 3 covering a cylinder 4 to form, together with a piston 31 , a combustion chamber 5 into which a main load 30 can be introduced.

[0054] Such as figure 1 , figure 2 , Figure 5 with Image 6 As can be seen in the figure, the cylinder head 3 accommodates an ignition prechamber 71 into which the spark plug 12 and the injector nose 16 of at least one injector 8 open and into which the pilot charge 9 can be introduced, Said pre-chamber 71 can communicate continuously with the combustion chamber 5 via a gas ejection duct 76 and via at least one gas ejection orifice 24 which communicates via a pre-chamber nose 75 to the chamber 5.

Abstract

The invention concerns an ignition insert (1) having an active prechamber, the insert comprising an insert well (72) arranged within a cylinder head (3) of an internal combustion engine (2), the well (72) housing a rotationally-indexed cylindrical insert body (70) in which an ignition prechamber (71) is arranged; an insert spark plug well (83) receiving a spark plug (12); and a radial injector port (88) aligned with a lateral injector well (73) arranged within the cylinder head (3) so as to accommodate an injector nozzle (16), the body (70) terminating in a prechamber nozzle (75) opening into a combustion chamber (5) and being held in the insert well (72) by attachment means (82) cooperating with clamping means (74).

Description

technical field [0001] The invention relates to an ignition insert with an active pre-chamber which makes it possible to accommodate the active pre-chamber in the cylinder head of an internal combustion engine with less space and in a minimally invasive manner. Background technique [0002] There are many concepts of active pre-chambers that serve as ignition means for igniting the main charge in the combustion chamber of an internal combustion engine. [0003] The term "active" pre-chamber is often used to describe a pre-chamber into which at least one fuel injector or at least one fuel-air mixture injector, with or without air injectors, opens, in addition to known electric spark plugs. [0004] Said concept is known, for example, from a pre-chamber called "turbulent jet ignition", patented and developed by the company "Mahle". This concept, which is the subject of patent EP 3001008 A1 published on March 30, 2016, provides a pre-chamber leading on the one hand to the spar...
