Abstract
An internal combustion engine wherein a variable compression ratio mechanism which can change the mechanical compression ratio and a detection sensor for detecting the mechanical compression ratio are provided and wherein the mechanical compression ratio is controlled based on the mechanical compression ratio detected by the detection sensor. When a signal line of the detection sensor breaks, the mechanical compression ratio is lowered to the minimum mechanical compression ratio.
