摘要

An internal combustion engine (1) comprising at least one cylinder (2) provided with at least one glow plug (11) adapted to heat a variable volume combustion chamber (9) within the cylinder (2), and an electronic control unit (12) which in turn comprises an estimation module (13) adapted to estimate the temperature (T GS ) of the glow plug (11) within the combustion chamber (9) and a control module (15) which is adapted to drive the glow plug (11) as a function of the estimated temperature (T GS ).
