摘要： A device for cancelling annoying sounds caused by operation of an internal combustion engine. An intake sound of the engine, and also a rotational speed of the engine, are obtained. The phase difference between the present intake sound and a desired intake sound is obtained using map data. The map data depends on the rotational speed of the engine and is specifically calculated so that at least the (n+0.5) harmonics (n integer.gtoreq.0) are cancelled. The phase data is used to drive a ceramic speaker or two oppositely directed ceramic speakers, to appropriately compensate the input sound.

摘要： In an internal combustion engine, a base fuel amount is calculated, and an air-fuel ratio deviation for each region is determined by a predetermined engine operating parameter when the engine is in a transient state such as an acceleration state or a deceleration state. A transient fuel correction amount is calculated in accordance with the calculated air-fuel ratio deviation for each region determined by the predetermined engine operating parameter. A fuel amount to be supplied to the engine is calculated by correcting said base fuel amount in accordance with the transient fuel correction amount.
