摘要： An engine control device for detecting misfire of an engine. Based on a detected crank angle of the engine, an angular velocity at a first crank angle at which the engine speed is close to a minimum within one combustion cycle of each cylinder is calculated as a pre-combustion angular velocity, and an angular velocity at a second crank angle at which the engine speed is close to a maximum within the same combustion cycle is calculated as a post-combustion angular velocity. An amount of rotation variation caused between the first and second crank angles is calculated based on the pre-combustion and post-combustion angular velocities of the same combustion cycle, and is compared with a predetermined misfire criterion to determine whether or not misfire has occurred. When misfire is detected, a required operation is performed, for example, a warning lamp is turned on or the fuel supply quantity is increased.

摘要： A system operable to control an exhaust gas emission of an engine, includes a catalytic converter; a fuel cutter, a change executor, a correlation value provider, an adjuster, and a controller. The change executor is operable to execute changing of an air-fuel ratio of the engine to a rich air-fuel ratio after the fuel supply is once stopped by the fuel cutter and then resumed. The correlation value provider is operable to provide a correlation value correlated to a change amount of the air-fuel ratio caused by the change executor based on a driving condition of the engine. The adjuster is operable to adjust the correlation value based on a parameter indicative of a capability of the catalytic converter. The controller is operable to cause the change executor to execute the changing based on the adjusted correlation value.
