Abstract: In an exhaust system, a first oxygen sensor is attached to an exhaust pipe connected to a standard cylinder in which the amount of injected fuel is the closest to the average of the amounts of fuel injected in a plurality of cylinders. A controller calculates the air-fuel ratio of the standard cylinder based on the value detected by the first oxygen sensor. Then, based on the difference between the calculated air-fuel ratio of the standard cylinder and a predetermined target air-fuel ratio, the amount of correction to the amount of fuel injected in the standard cylinder is determined such that the air-fuel ratio of the standard cylinder is equal to the target air-fuel ratio. Furthermore, based on the amount of correction to the amount of fuel injected in the standard cylinder, the amounts of correction of the other cylinders are determined.

Abstract: When content of a production slot database indicates that there is no free production slot which can be allocated to an ordered vehicle designated in received order information, a production management section exchanges a production slot assigned to a potential vehicle so that the ordered vehicle can be delivered by the desired date. When no potential vehicle slot is available, a production slot for an ordered vehicle can be exchanged with that for another ordered vehicle for which a production slot has been secured, and the production slot date of the other vehicle is postponed to another day before the desired delivery date. When a production slot is secured before the desired delivery date but the production slot for a part required for producing the ordered vehicle cannot be secured, management of exchange is performed for the part according to a parts production slot database to enable delivery of as many vehicles by the delivery dates desired by customers as possible.
