Abstract (en)
[origin: FR2849192A1] A functional engine component such as a sparking plug (1) has a collar (1b) which is supported by the shoulder (15c) of an intermediate element (15) screwed into an orifice (3) of the cylinder head (5). A nut (17) exerts pressure on the shoulder through a piezoelectric unit (19) which has contact and insulating rings (21,23). An electronic calculator (25) uses the cylinder pressure data to regulated a fuel injector (27)
