Abstract:
An evaporative fuel processing system adapted to be capable of detecting abnormality of an evaporative emission control system for storing, in a canister, evaporative fuel from a fuel tank for holding fuel to be supplied to an internal combustion engine, and purging evaporative fuel into the intake system of the engine. A first control valve is arranged across a passage extending between the fuel tank and the canister. A second control valve is arranged across a passage extending between the canister and the intake system of the engine. A third control valve is provided for an air inlet part of the canister communicatable with the atmosphere. Through operating these control valves to open and close them, the evaporative emission control system is negatively pressurized, and abnormality of this system is detected based on the pressure detected in this negatively pressurized state thereof. Timing for carrying out abnormality determination is determined depending on conditions of the fuel tank. Before starting the whole process for abnormality diagnosis of the system evaporative fuel stored in the canister is allowed to be purged for a predetermined time period. When the temperature of fuel in the fuel tank exceeds a predetermined value, the abnormality determination is inhibited.
Abstract:
A loose tube optical fiber cable with SZ stranding in which the units receive two or more laminated multicase ribbons stranded toward a central member with the stranding direction reversed at specific intervals. These multicase ribbons are twisted in the same direction as the stranding of the tube units, and a reverse stranding angle of the tube units is selected to be a value within a specific scope.
Abstract:
A combustion state-determining system for an internal combustion engine has an ECU which determines a misfiring state of the engine, and calculates a misfiring rate of the engine, based on the result of the determination of the misfiring state. A catalyst temperature sensor detects the temperature of a catalytic converter as the exhaust system temperature, and the ECU determines the combustion state of the engine, based on the detected exhaust system temperature and the calculated misfiring rate. A combustion state control system restrains the output from the engine, based on the determination result of the combustion state-determining system.
Abstract:
An evaporative fuel-processing system for an internal combustion engine includes an evaporative emission control system comprising charging passage extending between the canister and a fuel tank, a purging passage extending between the canister and an engine intake system, an open-to-atmosphere passage communicating the interior of the canister to the atmosphere, a purge control valve for opening and closing the purging passage, and an open-to-atmosphere valve for selectively opening and closing the open-to-atmosphere passage. A tank internal pressure sensor detects pressure within the evaporative emission control system. An ECU introduces negative pressure from the engine intake system into the evaporative emission control system and the fuel tank by opening the purge control valve and closing the open-to-atmosphere valve. The ECU compares a pressure value detected by the tank internal pressure sensor with a predetermined pressure value, and controls the valve opening amount of the purge control valve, based on the comparison results.
Abstract:
An evaporative fuel-processing system for an internal combustion engine includes an evaporative emission control system having a fuel tank, a canister, a passage extending from the canister to an intake passage of the engine, and a purge control valve arranged across the passage, and a pressurization device for pressurizing the interior of the evaporative emission control system. An ECU actuates the pressurization device to bring the evaporative emission control system into a positively pressurized state, after the purge control valve and an open-to-atmosphere control valve arranged across a passage connected to the canister are closed, and detects an amount of evaporative fuel generated in the fuel tank. The ECU determines whether or not a leakage occurs from the evaporative emission control system, based on a rate of variation in pressure within the evaporative emission control system, and a reference value which is determined based on the amount of evaporative fuel detected.
Abstract:
An evaporative fuel-processing system for an internal combustion engine, incorporates an evaporative emission control system in which a first control valve is arranged across an evaporative fuel-guiding passage extending between a fuel tank and a canister, a second control valve across a purging passage extending between the canister and the intake system of the engine, and a third control valve at an air inlet port of the canister, respectively. An ECU generates operation command signals to the first to third control valves for closing or opening the same to bring the evaporative emission control system into a predetermined negatively pressurized state. The ECU is responsive to an output from a parameter sensor which detects at least one of vehicle speed, temperature within the fuel tank, and an amount of fuel within the fuel tank, for determining whether there is an abnormality in the evaporative emission control system, based upon an output from a tank internal pressure sensor. The output is obtained when the evaporative emission control system has been brought into the predetermined negatively pressurized state, when the value of at least one parameter detected by the parameter sensor falls within a predetermined range.
Abstract:
A tank internal pressure-detecting device for an internal combustion engine having an evaporative emission control system for controlling purging of evaporative fuel generated in a fuel tank thereof into an intake system thereof. An ECU interrupts purging of evaporative fuel by the evaporative emission control system for a predetermined period of time after the engine is started. The ECU causes control valves of the evaporative emission control system to open the interior of the fuel tank to the atmosphere, and stores a value of pressure within the fuel tank detected by a tank internal pressure sensor as a reference value while the purging is being interrupted and at the same time the interior of the fuel tank is opened to the atmosphere. The ECU corrects an output value of the tank internal pressure sensor, based upon the reference value stored.
