摘要： A method for producing a low carbon deep drawing quality steel or high strength steel in the form of a strip or sheet. At least one of carbide or nitride forming elements is added to the low carbon steel to provide therein 0.015 to 0.10% Sol Al, 0.01 to 0.10% Nb, 0.01 to 0.10% Ti and 0.01 to 0.15% V. The steel is cast or bloomed to form a slab which is held above the Ar.sub.3 point for keeping the carbide and nitride forming elements in a dissolved state. Then, without allowing the temperature to fall below the Ar.sub.3 point, hot rolling and hot finishing rolling are directly carried out at a temperature above the Ar.sub.3 point. Thereafter, if necessary and desirable, the thus-rolled slab or sheet is subjected to cold rolling and annealing.

摘要： An engine air-fuel ratio control system is configured to use a rich air-fuel ratio immediately after starting an engine such that the air-fuel ratio converge rapidly toward a stoichiometric value and then afterwards start an air-fuel ratio feedback control. Upon determining an air-fuel ratio sensor is active, a stabilization fuel quantity increasing factor that is a component of a target air-fuel ratio revising coefficient is decreased at a higher rate than the rate used before the air-fuel ratio sensor was determined to be active. Air-fuel ratio feedback control is started when the air-fuel ratio corresponds to a stoichiometric air-fuel ratio. After starting air-fuel ratio feedback control, an unburned fuel quantity compensating value is set based on the stabilization fuel quantity increasing factor in effect at that point in time and added to the target air-fuel ratio revising coefficient while, simultaneously, the stabilization fuel quantity increasing factor is set to zero.

摘要： A state quantity &sgr;(n) of a switching function is calculated based on a predetermined target air-fuel ratio TGABF, a detected air-fuel ratio AFSAF detected by a sensor (16), and a state equation derived from a transfer function Geng(q) of a secondary discrete system, representing the correlation between an air-fuel ratio of an air fuel mixture in a combustion chamber (1A) and the detected air-fuel ratio (S14). The air-fuel ratio is feedback corrected by applying a sliding mode control process based on the difference between the target air-fuel ratio TGABF and the detected air-fuel ratio AFSAF, and the state quantity &sgr;(n) (S14-S21). The response and robustness of the air-fuel ratio control are enhanced by using a physical model of the secondary discrete system.

摘要： In a four-stroke cycle multi-cylinder internal combustion engine (2), a controller (1) controls fuel injectors (8) to inject fuel for the cylinder (#1) in the intake stroke immediately after the first cylinder-stroke identification is performed. Due to this fuel injection control, the fuel is necessarily injected before the first combustion occasion at any cylinder (#1-#4), cylinder dependent fluctuation of air-fuel ratio when the first combustion takes place in the respective cylinders (#1-#4) is prevented. Further, in a predetermined low temperature range, the controller (1) controls fuel injectors (8) to perform a preliminary fuel injection for all the cylinders (#1-#4) before the first cylinder-stroke identification, so the fuel amount required for the first combustion is ensured for all the cylinders (#1-#4).

摘要： With an electronically controlled throttle type internal combustion engine, where a target opening of a throttle valve is set according to a required output of the engine, and the throttle valve is opened and closed with an actuator so as to obtain a target opening; air quantity learning for learning and correcting the target opening of the throttle valve so as to obtain a target intake air quantity is performed by comparing an intake air quantity estimated based on a detection value of the throttle valve opening and an actually detected intake air quantity, at the time of idling the engine. After completion of the air quantity learning, friction learning for learning and correcting the target opening of the throttle valve so as to obtain a target engine output is performed while feedback controlling the throttle valve opening so that the engine rotation speed approaches a target idle rotation speed, at the time of idling the engine. In this way, it is possible to effect control which makes the throttle valve opening correspond very accurately to the required engine output, over a long period of time.
