Abstract
The invention provides torque correction during both homogeneous combustion and stratified combustion. Torque correction is made in response to a torque correction demand (produced when, for example, a gear shift is effected, the air conditioner is turned on, or fuel cut recovery is effected) by correcting the spark timing (or the spark timing and air-fuel ratio) during homogeneous combustion and by correcting the air-fuel ratio during stratified combustion.
