Abstract: A clustering unit calculates, for clusters in a descending order of the number of pixels belonging thereto, a distance from a feature vector of a processing object pixel and a representative feature vector of an object cluster, and compares the distance with a first threshold. The processing object pixel is stored in a memory or the like as a pixel belonging to an object cluster when the distance is judged to be less than or equal to the first threshold.

Abstract: Disclosed is a fuel vapor treating apparatus, in which fuel vapor evaporated in a fuel tank is not released directly into the atmosphere but is collected and treated. This apparatus is provided with a canister for collecting fuel vapor and a purge line for purging the fuel vapor collected in the canister to an intake passage of an engine. The canister has a first control valve for controlling introduction of fuel vapor thereto. The canister also has a second control valve for controlling the introduction of outside air and the exhaust of gas therefrom. The first control valve communicates with a vapor line extending from the fuel tank and is opened whenever the internal pressure of the fuel tank exceeds a predetermined level to introduce fuel vapor from the fuel tank into the canister. The second control valve is designed to communicate with the atmosphere and is opened whenever fuel is purged through the purge line to the intake passage to introduce outside air into the canister.

Abstract: An air-fuel control system for an internal combustion engine is provided in which air-fuel ratio control system a deviation effect due to an amount of evaporated fuel distributed to each cylinder group differing from cylinder group to cylinder group is eliminated when a deviation of air-fuel ratio due to aging of the engine has been learned. A difference value between the air-fuel correction factor and a value of a range of distribution deviation of the air-fuel ratio is obtained so that the difference value is used as the air-fuel correction factor. The difference value is obtained when the engine is determined to be in a purging operation by the first determining means, and when it is determined that learning of the air-fuel ratio correction factor is not completed. The difference value represents a true deviation of the air-fuel ratio due to aging of the engine parts.

Abstract: An air-fuel ratio control system for an internal combustion engine which includes an evaporative fuel purge system having a canister for temporarily storing fuel vapor, detects an air to fuel ratio in the exhaust gas from the engine. An air-fuel ratio controller controls the air-fuel ratio in exhaust gas from the engine by varying a fuel quantity supplied to the engine so that the air-fuel ratio approaches a predetermined target air-fuel ratio. The evaporated fuel is purged from the canister at a specific purging rate determined based on engine operating conditions. An air-fuel ratio-shift is controlled based on the derivation of an amount by which the air-fuel ratio has shifted from the target air-fuel ratio due to a cause independent of the purging operation.

Abstract: An air-fuel ratio control apparatus constructed, in an engine of a type storing evaporated fuel generated in a fuel tank in a canister and thereafter drawing off the evaporated fuel to an intake side of an engine through a bleedoff passage, so as to inhibit renewal of an air-fuel ratio learning value when the evaporated fuel concentration is at a predetermined value or higher in case of learning and renewal of an air-fuel ratio in order to make feedback control of the air-fuel ratio of an air-fuel mixture supplied to the engine. In an apparatus which adsorbs evaporated fuel generated in a fuel tank in a canister and purges the evaporated fuel adsorbed in the canister to an intake side of an internal combustion engine together with air through a purge valve, an air-fuel ratio learning value is renewed in accordance with a deviation between an air-fuel ratio feedback FAF value detected by an oxygen sensor and a FAFSM value obtained by smoothing the FAF value with a large smoothing constant.
