Abstract
An internal combustion engine control device having an exhaust gas recycle system which has an exhaust gas recycle line to an air intake pipe, the engine control device comprises at least pressure detect means as one of driving condition detect means for detecting a pressure for calculating an exhaust gas flow rate while said exhaust gas is recycled. A trouble detect means is provided for detecting a trouble in the exhaust gas recycle system on the basis of the pressure value detected by the pressure detect means. An engine control means is provided for controlling the engine speed based on the detected driving conditions by the driving condition detect means and based on an atmospheric pressure calculated from the pressure value detected by the pressure detect member.
