摘要： 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. Further, renewal of the air-fuel ratio learning value is inhibited when the concentration of the evaporated fuel is high, and renewal of the air-fuel ratio learning value is executed even during purge execution by the purge valve when the concentration is low.

摘要： 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. The first amount, which is relatively constant over time in comparison to a second amount of air-fuel ratio shift occurring as a result of the purging operation, is derived based on a first detected air-fuel ratio-shift amount when the purge system is purging at a first purging rate. The second air-fuel ratio-shift amount is detected when the purge system is purging at a second purging rate different from the first purging rate.

摘要： 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. The second control valve is opened whenever the internal pressure of the canister exceeds a predetermined level to exhaust fuel-free gas left after collection of the fuel. Both the first control valve and the second control valve are diaphragm check valves. The control valves are designed to be readily detached from the canister.

摘要： A specific region in each frame image input after a detection process has been completed a predetermined number of times or more is estimated from a specific region detected from a past frame before the frame. The shift between the specific region detected from a first frame image input after the detection process has been completed the predetermined number of times or more and the specific region estimated for the first frame image is obtained. When the shift falls within a predetermined range, an encoding parameter to encode the specific region estimated for a second frame image input at a point the detection process for the first frame image has been completed with a higher image quality than that of regions other than the specific region is set.

摘要： An area where a specific object is captured is extracted as a specific area from the image of a frame of interest, and the evaluation value of the specific area is obtained using a predetermined evaluation formula. It is determined whether the evaluation value of the specific area in a frame preceding the frame of interest has exceeded a predetermined threshold. When it is determined that the evaluation value of the specific area has exceeded the predetermined threshold, the frame of interest is encoded to set the code amount of the specific area in the image of the frame of interest to be smaller than that of the specific area in the image of the frame preceding the frame of interest.
