Definitions

  • misfire incomplete combustion due to engine misfire
  • misfire diagnosis and detection means have been presented and implemented conventionally.
  • the crank angle position information at each point of the two crank angles is stored in advance in the storage device in the computer in the engine control device, and the information from the crank angle sensor and the cam angle sensor provided in the engine is stored.
  • the index value of the combustion state is calculated by the arithmetic processing device of the computer based on the above, it is less likely to be affected by the disturbance as compared with the method of searching with a fast or slow rotation speed.
  • the calculation of the angular acceleration can be simplified.
  • the cylinder is out of order due to a misfire without determining whether or not the temperature of the exhaust gas temperature sensor exceeds a specified value. If it is suspected that a misfire that adversely affects the catalyst device, which is an aftertreatment device for engine exhaust purification, will occur, in addition to the above-mentioned misfire determination information, it will be downstream of the catalyst exhaust. By using the information of the installed exhaust temperature sensor (Tcat), if this exceeds the specified temperature, it will be judged as a catalyst melt loss fire failure, so that it will be erroneously judged even under the failure condition with a low misfire rate. There is no.
  • FIG. 1 is a schematic view of a 4-cycle spark ignition engine system of a misfire diagnostic device showing a preferred embodiment for carrying out the present invention, which has basically the same configuration as the conventional example and connects the engine body 1.
  • the crank angle detection rotary disk 23 connected to the rod (crank shaft) 22 has irregularities arranged at predetermined angular intervals, and the crank angle sensor (CPS) 35 is arranged on the crank angle detection rotary disk 23.
  • CPS crank angle sensor
  • the crank angle position information at each point of the two crank angles shown in FIG. 1 is stored in advance in a storage device in the computer in the engine control device (ECU) 29, and the engine main body.
  • the engine rotation speed is calculated by calculating the index value of the combustion state by the arithmetic processing device of the computer.
  • XTM angular acceleration
