摘要： An air-fuel ratio control system for an internal combustion engine has a sensor which detects the air-fuel ratio of exhaust gases in an exhaust passage of the engine emitted from a plurality of cylinders. An air-fuel ratio of a mixture supplied to each of a plurality of cylinders is estimated, based on the detected air-fuel ratio and a model representative of a behavior of the exhaust passage. A cylinder-by-cylinder air-fuel ratio control amount is calculated for use in controlling the air-fuel ratio of the mixture supplied to the each of the cylinders in a feedback manner responsive to the estimated air-fuel ratio of the mixture such that the estimated air-fuel ratio of the mixture supplied to the each of the cylinders is converged to a desired air-fuel ratio. A learned value of the cylinder-by-cylinder air-fuel ratio control amount is calculated. When the difference between the detected air-fuel ratio and the estimated air-fuel ratio of the mixture supplied to the each of the cylinder is larger than a predetermined value, the calculation of the learned value of the cylinder-by-cylinder air-fuel ratio control amount is inhibited.

摘要： Disclosed herein is an evaporative emission control system which can prevent changes in fuel component in the fuel tank and vacuum boiling in the fuel pump to thereby accurately control the air-fuel ratio to a desired value and ensure smooth supply of the fuel. The control system includes an evaporative fuel passage for connecting a fuel tank and an intake system of an internal combustion engine, and a control valve is provided in the evaporative fuel passage for opening and closing the evaporative fuel passage. It is determined whether or not a fuel temperature is higher than or equal to a predetermined fuel temperature. If the fuel temperature is higher than or equal to the predetermined fuel temperature, the opening operation of the control valve is disabled.

摘要： Disclosed herein is an evaporative emission control system which can properly control the ratio between a tank purge amount and a canister purge amount to realize quick pressure reduction in a fuel tank and ensuring the storage capacity of a canister in a well balanced fashion. A target pressure in controlling the pressure in the fuel tank at a negative pressure and a detected pressure in the fuel tank are compared with each other. When the difference between the target pressure and the detected pressure is large, tank purge is preferentially carried out to open a tank pressure control valve. When the detected pressure is in the vicinity of the target pressure, canister purge is preferentially carried out to purge the evaporative fuel stored in the canister.

摘要： An air-fuel ratio control system for an internal combustion engine includes an air-fuel ratio sensor for detecting the air-fuel ratio of exhaust gases from the engine. An ECU estimates the air-fuel ratio of a mixture supplied to each of the cylinders cylinder by cylinder in response to an output from the air-fuel ratio sensor, by using an observer based on a model representative of the behavior of the exhaust system. Cylinder-by-cylinder air-fuel ratio control amounts corresponding respectively to the cylinders are calculated for carrying out feedback control of the air-fuel ratio of the mixture such that each of the estimated air-fuel ratio is converged to a desired value. One of the cylinder-by-cylinder air-fuel ratio control amounts corresponding to one of the cylinders is held at a predetermined value, and it is determined whether relationships in value between ones of the cylinder-by-cylinder air-fuel ratio control amounts corresponding respectively to cylinders other than the one cylinder and a plurality of predetermined determination values meet a predetermined determination pattern. When the relationships meet the predetermined determination pattern, it is determined that the response speed of the air-fuel ratio sensor has changed.

摘要： Disclosed herein is a programmable controller comprising a central processing unit (CPU) and a delay element. The CPU operates on simulated input information in accordance with a sequence program. The result of the operation by the CPU is sent to the delay element. The delay element in turn supplies the operational result with a delay time setting and feeds the result back to the CPU as simulated input information. The delay element is also capable of setting any delay time for simulation as desired.

摘要： Machine language instructions corresponding to sequence instructions that are stored in a first memory are stored at addresses of a second memory corresponding to operating codes of the sequence instructions, and a processing unit executes a sequence control by the instructions fetched from the second memory. A jump instruction with non-designated jump-to address is stored in the second memory. Following fetching of the jump instruction from the second memory, the processing unit fetches the sequence instruction to be next executed from the first memory, and the operation code of that sequence instruction is transferred to the processing unit as a jump-to address of the jump instruction.

摘要： A programmable controller comprises an input circuit including a plurality of signal input terminals which receive signals from a plurality of external input devices, and a power feed terminal and a ground terminal which are respectively exposed in order to supply a power source voltage from outside the programmable controller. Also, current regulator elements are respectively located between the power feed terminal or the ground terminal and the plurality of signal input terminals. Owing to this construction, the range of power source voltages to be supplied to the input circuit can be widened, and various external input devices can be connected without altering internal circuitry. A plurality of power sources of fixed voltages which are generally used are built in, whereby a user need not especially prepare a power source and can be freed from the labors of wiring etc. The programmable controller can be readily conformed to the specifications of the external input devices, making it easy to cope with these devices. Since unidirectional photocouplers which are economical may be employed, the programmable controller can be constructed at low cost. Moreover, since the transfer ratios of the input signals can be held constant, a stable performance can be attained.
