摘要： An abnormality diagnosis apparatus for performing a leak check of an evaporative fuel processing system which includes a fuel tank, a canister for storing evaporative fuel generated in the fuel tank, a purging passage for connecting the canister to an intake system of an internal combustion engine, and a purge control valve provided in the purging passage. A process of reducing the pressure in the evaporative fuel processing system is executed with a limited flow rate of gases passing through the purge control valve when performing the leak check in an idling condition of the engine. The limited flow rate is set to a value equal to or smaller than a predetermined flow rate which is smaller than the maximum flow rate applied to the leak check performed in operating conditions other than the idling condition. The leak check is performed on the basis of a change in the pressure in the evaporative fuel processing system after the pressure reduction process.

摘要： A control system is disclosed that accelerates the rise in temperature of a catalyst provided in an exhaust system of an internal combustion engine. The system increases the intake air amount after the engine starts and retards the ignition timing according to a rotational speed of the engine. In this control system, a failure of the catalyst temperature rise acceleration control is diagnosed according to the engine rotational speed and/or a retard amount of the ignition timing during the execution of the catalyst temperature rise acceleration control. The above failure may also be diagnosed according to at least one of the ignition timing and the engine rotational speed when decreasing the intake air amount during the execution of the catalyst temperature rise acceleration control. The above failure may also be diagnosed according to a detected catalyst temperature and an estimated catalyst temperature.

摘要： The present invention enables a large leak to be accurately detected by providing an evaporated fuel treatment apparatus for an internal combustion engine. The apparatus comprises the evaporated fuel discharge prevention system including a fuel tank, a canister having an opening to the atmosphere, a passage allowing the fuel tank to communicate with the canister, a purging passage allowing the canister to communicate with the intake manifold of the engine. The apparatus also comprises a pressure sensor for detecting the pressure of the evaporated fuel discharge prevention system, and a controller coupled to the pressure sensor for judging the presence of a first leak in the evaporated fuel discharge prevention system if a change in the pressure from the pressure sensor is small. The controller further checks a change in the pressure from said pressure sensor when closing said system after placing said system under negative pressure. The controller judges the presence of a large leak if the first leak is judged and the pressure increases instantaneously upon closing said system.

摘要： An evaporative fuel-processing system for an internal combustion engine includes a canister, a charging passage extending between the canister and a fuel tank, a purging passage extending between the canister and the intake system of the engine, an open-to-atmosphere passage for relieving the interior of the canister to the atmosphere, a charge control valve for opening and closing the charging passage, a purge control valve for opening and closing the purging passage, a vent shut valve for opening and closing the open-to-atmosphere passage, and a pressure sensor for detecting pressure within the charging passage. When the engine is in a predetermined operating condition, the interior of the fuel tank is negatively pressurized into a predetermined negatively pressurized state by opening the purge control valve and the charge control valve and closing the vent shut valve. When a predetermined time period has elapsed from the start of the negative pressurization before the interior of the fuel tank is set to the predetermined negatively pressurized state, the purge control valve and the charge control valve are closed, and an abnormality of the fuel tank is determined based on the pressure detected by the pressure sensor immediately before and after the closing of the purge control valve and the charge control valve.

摘要： An evaporative emission control system for an internal combustion engine has a purge control valve arranged in a purging passage connecting between a canister and an intake passage of the engine. The evaporative emission control system has a self-diagnosis function of determining whether the evaporative fuel emission control system is normal or abnormal from a change in a value of a parameter measured based on an output from an exhaust gas component concentration sensor arranged in an exhaust passage of the engine, which change is detected when the opening of the purge control value is changed, and a variation in pressure within the intake passage at a location downstream of a throttle valve arranged therein when the opening of the purge control valve is changed.

摘要： Disclosed herein is a turning zigzag embroidery machine adapted to read in from outside needle center data N, which permits scaling up or down or alteration of an embroidery pattern, and to convert the needle center data into frame center data C to reproduce an embroidery pattern in an improved form. Of externally read-in needle center data N (.DELTA.X, .DELTA.Y, .theta., W) and the data of needle center N on X-Y axes, this turning zigzag embroidery machine transforms, for example, data Nk (Xk, Yk, .theta.k, Wk) of needle center Nk into data Ck (xk, yk, .theta.k, Wk) of frame center Ck on x-y axes by arithmetic conversion. Then, in order to advance an embroidering needle 10 to the needle center Nk, a rotatable frame is shifted in the directions of x- and y-axes and at the same time it is turned through a given rotational angle .theta.=.theta.k in the direction of arrow E. At each of the advanced needle center positions, the embroidering needle is imparted with a rocking motion across a rocking width Wk to make a stitch at a given stitch point Sk, thereby reproducing an embroidery pattern on a cloth.
