#CMT# #/CMT# The method involves acquiring a first signal relating to a passage frequency of a first tooth (31) of a toothed wheel (30) of a passage sensor (33). Pressure of an intake gas is determined in an air distributor (12). Stopped or started states of an internal combustion engine (1) are detected based on the first signal and the pressure of the gas, where the engine is equipped with a crankshaft (10), and the toothed wheel is rotated in relation to the crankshaft. A second signal relating to a passage frequency of a second tooth (32) of the toothed wheel of the passage sensor is acquired. #CMT# : #/CMT# An independent claim is also included for an internal combustion engine. #CMT#USE : #/CMT# Method for detecting a state e.g. started state, stopped state and intermediate state, of an internal combustion engine (claimed) that is utilized in a vehicle. #CMT#ADVANTAGE : #/CMT# The method enables detecting the stopped or started states of the internal combustion engine based on the signal and the pressure of the gas, and acquiring the second signal relating to the passage frequency of the second tooth of the toothed wheel of the passage sensor such that the second signal is reactive when the crankshaft ceases turning, thus accurately realizing deduction of state of the engine with increased reliability while avoiding unexpected lighting of indicators on an instrument panel of the vehicle, and hence improving diagnosis of performance of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an internal combustion engine. 1 : Internal combustion engine 10 : Crankshaft 12 : Air distributor 30 : Toothed wheel 31, 32 : Teeth 33 : Passage sensor. |
