摘要

A device comprising at least one cylindrical liner (5) of which one axial end is covered by the wall of the combustion chamber (2) in the cylinder head (1) of the engine, means (6) for generating a gas flow in the liner through at least one inlet, a longitudinal probe (7) radially inserted through the liner (5) and provided with at least two separate internal channels (8, 9) communicating with the space inside the liner (5) via two apertures that lie in a plane (P) parallel to the axis of the liner (5) and intersect one another and the longitudinal probe axis in said plane (P), as well as a differential pressure gauge (13) of which each inlet is connected to a respective internal channel (8, 9) of the probe (7).
