摘要

1. Preheating plug (60) for air-compressing engines, equipped with a turbulence prechamber (200), comprising a bottom portion (61) and a tip (62) intended to project into the prechamber (200), characterised in that this tip (62) has a cross-section, through a plane perpendicular to its longitudinal axis, which is oblong in contour (66) and aerodynamically shaped with respect to a current of gas directed parallel to the axis (660) of the largest dimension of the contour.
