摘要： A fuel control system for an internal combustion engine capable of correcting an inlet air flow rate, used for the computation of a fuel injection, in consideration of a blow-back flow rate. The inlet air flow rate is detected by a hot-wire type sensor and sampled by a control unit. The control unit determines whether or not the sampled inlet air flow rate has reversed twice its gradient from the negative one to the positive one between predetermined crank angles of the engine and computes the blow-back flow rate subtracted from the inlet air flow rate.

摘要： A control apparatus with a fail-safe function not only serves to enhance acceleration performance of a motor vehicle but also prevents a runaway upon occurrence of a failure in a throttle control system. An accelerator pedal actuation detector detects a magnitude of depression of an accelerator pedal by the driver. A vehicle speed detector detects a running speed of the vehicle. A gear ratio detector detects a gear ratio or gear position of a transmission. A plurality of target throttle opening patterns representing relations between target values of throttle opening degree and depression magnitudes of the accelerator pedal are stored in a memory. A first controller selectively determines an optimum target throttle opening pattern on the basis of the vehicle speed and the gear ratio to thereby control a throttle actuator for actuating a throttle in accordance with the selected pattern. An intake air quantity detector detects a quantity of intake air fed to an engine of the motor vehicle. A comparator compares a target intake air quantity determined on the basis of the depression magnitude of the accelerator pedal and an actual intake air quantity. When the actual intake air quantity is substantially greater than the target one, a second controller reduces the engine output power by temporarily stopping the fuel supply to the engine or by temporarily halting operations of some engine cylinders.

摘要： The invention relates to a novel fuel controller of an internal combustion engine. In particular, it relates to a novel fuel controller which securely corrects characteristic variation with time of air-flow sensor used for controlling flow of fuel. The fuel controller embodied by the invention incorporates a memory which stores the negative feedback correction value of air-fuel ratio or the value related to it at the flow-volume point representing variation of characteristic of air-flow sensor or at an adjacent point of it so that the basic volume needed for controlling flow of fuel can be corrected by applying the content of memory. As a result, even if characteristic of the air-flow sensor varies, the system can achieve satisfactory control condition. The fuel controller inhibits renewal of the study on the negative feedback correction value for the predetermined period in accordance with the opening/closing condition of the purge-control valve. As a result, the fuel controller can securely and constantly perform satisfactory fuel-flow control operation without being influenced by erroneous air-fuel ratio caused by presence of purged gas.

摘要： A system for controlling the operation of an internal combustion engine on the basis of air/fuel ratios and engine loads. A flow rate of intake air sucked into the engine and the cycle of engine revolutions are detected to determine an average flow rate of intake air, which is then used in cooperation with a compression ratio and an engine displacement to determine a net flow rate of intake air or the charging efficiency of the engine. This parameter represents a precise engine load and is used to regulate fuel injected into the engine. As a result, engine operations may be optimally controlled even during transitional operating states of the engine.
