Title:

燃焼異常指数を結合することにより内燃機関のミスファイヤを検出する方法

Document Type and Number:

Japanese Patent JP4340285

Kind Code:

B2

Abstract:

The method involves calculating a current value of an index representative of irregularities of engine running at a time (t). Current value of observation function E(t) at the same time is calculated from the current value of the index. The current value of E(t) is compared with a predetermined threshold value. Combustion false start of the engine is detected when the current value of E(t) exceeds the threshold value. Index is calculated from linear combination of elementary indexes, each index representing running irregularities of engine. Each elementary index is multiplied by predetermined coefficient obtained from similar running conditions on reference engine.
