摘要： An evaporated fuel gas purging system performs breakdown analysis without deterioration of drivability and exhaust emission even when the amount of purged fuel gas is large. During introduction of negative pressure into the purge system, a control value DUTY sets opening of a purge control valve and a purge flow amount GPG is derived from a map based on differences in the control value DUTY, atmospheric pressure and intake pipe pressure. Thereafter, a purge ratio PGR is calculated from intake air GA and purge flow GPG (PGR=GPG/GA), and a fuel injection correction value FAFLEAK=PGR.times.(FGPGAV-1).times.K1 is calculated, with FGPGAV-1 being the air-fuel ratio feedback correction deviation per 1% purge ratio, and K1 being an error correction coefficient. Then, the fuel injection correction FAFLEAK is guard-processed to maintain it below an upper limit guard value KFLEAKMX.

摘要： A correction apparatus for correcting an output of an oxygen sensor installed in an exhaust pipe of an internal combustion engine to measure the concentration of oxygen contained in exhaust gas. The apparatus works to execute a fuel cut operation to bring the pressure in the exhaust pipe to the atmospheric pressure and enters an under-atmosphere correction mode to sample an output of the oxygen sensor and determine a correction factor compensating for a deviation of the sampled output from a reference value representing an actual concentration of oxygen. The apparatus also works to calculate the pressure in the exhaust pipe after start of the fuel cut and determine whether the under-atmosphere correction mode is to be entered or not based on the pressure of exhaust gas, thereby ensuring the accuracy in correcting the output of the oxygen sensor regardless of a variation in the pressure of exhaust gas.

摘要： The digital control unit of the present invention relates to improvements in what is called recent control, and more particularly relates to the idle rotating speed control unit of an internal combustion engine in which the idle rotating speed can be quickly converged to the target rotating speed in the case where a load given from the outside varies. Especially, when the value of the state variable is reversely calculated from the state in which open loop control is conducted, the initial value can be accurately determined.

摘要： A fuel supply system has an in-tank module. The in-tank module is provided with a pump, a filter, a pressure regulator and a pressure sensor detecting a fuel pressure. The pressure sensor is disposed on or at a vicinity of the fuel pump so that the pressure sensor easily detects a pulsation component due to the pump. A fuel pump controller includes a speed detection module which detects the rotation speed of the fuel pump based on a cycle of the pulsation component of the pressure detected by the pressure sensor. Thus, the rotation speed of the fuel pump can be indirectly detected by means of the pressure sensor.

摘要： Deterioration of a catalyst of a catalytic converter of an internal combustion engine is detected, during negative feedback control of the air-fuel ratio based on an output signal from at least one of a pair of O.sub.2 sensors disposed respectively upstream and downstream from the catalyst in the exhaust system. Detection is executed after changing the feedback period, which is the period of alternation of a feedback correction coefficient used to control the fuel injection quantity, with the change in period being such as to provide improved accuracy of detection of catalyst deterioration. The change may consist of a single step change, in which the feedback period is set to a specific predetermined value at which the output signal amplitude from the downstream sensor, or the phase difference between the two sensor output signals, should be within predetermined limits if the catalyst is in satisfactory condition.

摘要： An apparatus for detecting a purification factor of a catalyst for purifying an exhaust gas of an internal combustion engine comprises a catalyst disposed in an exhaust system of the internal combustion engine for purifying an exhaust gas, first and second air-fuel ratio sensors disposed upstream and downstream of the catalyst for detecting air-fuel ratios, respectively, a response delay time difference detecting device for detecting differences in response delay time between the first and second air-fuel ratio sensors in respective different operation states of the engine, a purification factor detecting device for detecting a purification factor of the catalyst on the basis of a deviation between the first and second response delay time differences detected in respective different operation states of the engine. Since the purification factor of the catalyst is detected on the basis of a deviation between the first and second response delay time differences detected in the respective different engine operation states, the purification factor of the catalyst can be detected with high accuracy independently of response characteristics of the first and second air-fuel ratio sensors themselves.
