摘要： An improvement in an exhaust gas purification apparatus wherein a detector senses the operation of a device for injecting additional intake air into the intake passage and triggers a timing unit. The timing unit produces a signal for a predetermined amount of time which holds open a control valve for introducing secondary air into the exhaust passage ahead of the catalytic converter. This structure enables the reduction of harmful components of the exhaust gas produced during a gear-change operation of the engine without greatly overheating the catalytic converter.

摘要： An air intake side secondary air supply system for an internal combustion engine equipped with an automatic choke valve and a fast idle system is provided with a detection means for detecting an operating condition of the engine in which the fast idle system is operated to open the throttle valve. The supply of the secondary air for the feedback control is stopped when a detection signal is produced by the detection means so that the feedback control of the air-fuel ratio is suspended when the throttle valve is opened by means of the fast idle system while the choke valve may be substantially closed. Thus, a hunting of the engine speed which might have occured after the start of the feedback control is prevented.

摘要： A device for increasing an amount of fuel to be supplied to an engine includes a fuel increasing mechanism for supplying an added amount of fuel to the engine, and an electric control circuit including a low-temperature sensor for detecting a low temperature of the engine to produce a first signal capable of actuating the fuel increasing mechanism, and a neutral-gear-condition detector for detecting the neutral-gear-condition of a gear transmission associated with the engine to produce a second signal. The fuel increasing mechanism is inactivated in response to the second signal from the neutral-gear-condition sensor by overriding the low-temperature sensor to prevent the increase of fuel while the gear transmission is in neutral. A second embodiment employs additional sensors for air temperature, engine r.p.m., vehicle speed and the park-condition of an automatic transmission also for controlling the fuel increase.

摘要： An apparatus for detecting a neutral state of a transmission gear of a vehicle detects an engine rotational speed, a vehicle speed, and a condition in which the engine output power is transmitted to the transmission gear through a clutch. The apparatus judges that the transmission gear is in the neutral state when a ratio between the engine rotational speed and the vehicle speed is in any one of predetermined ranges. The apparatus also judges that the transmission gear is in the neutral state when a variation of the ratio between the engine rotational speed and the vehicle speed within a predetermined time period is greater than a predetermined value.

摘要： The present invention relates to a control system for an engine driven generator, and more specifically, to a control system for controlling the field current to the field coil of the generator to prevent a rapid decrease in the engine rotational speed throughout a transient period when an electric load, such as a head light or an air conditioner, is switched on and begins to draw current.In one embodiment of the invention, the control system comprises digital control means for repeatedly alternating throughout the transient period between calculating an on period and switching the field current on for the on period, and then calculating an off period and switching the field current off for the off period. The digital control means also detects a high output torque operating condition of the engine, and when such a condition is present, switches the field current on throughout the entire transient period.In a second embodiment of the invention, the control system comprises analog or "hard-wired" control means for performing the same functions as the digital control means.

摘要： An idling speed control system for controlling idling rotational speed of an internal combustion engine. A vacuum-operated actuator having a diaphragm defining a vacuum chamber controls opening and closing of a throttle valve in response to pressures supplied from a change-over control valve to the vacuum chamber. The change-over control valve selectively supplies the vacuum chamber with a first control pressure for opening the throttle valve and a second control pressure for closing same. An electronic control unit generates an on-off control pulse signal having a pulse repetition period corresponding to rotational speed of the engine, one of on-period or off-period of the on-off control pulse signal having a predetermined constant value, and supplies the change-over control valve with the on-off control pulse signal. A valve opening-correcting device is operatively connected to the throttle valve and responsive to at least one predetermined external load applied on the engine for correcting to a larger opening the opening of the throttle valve which is determined by the change-over control valve in response to the on-off control pulse signal.

摘要： An idling speed control system for controlling idling rotational speed of an internal combustion engine. A vacuum-operated actuator having a diaphragm defining a vacuum chamber controls opening and closing of a throttle valve in response to first and second control pressures supplied from a change-over control valve to the vacuum chamber. An electronic control unit generates, in response to an on-off control pulse signal having a period corresponding to rotational speed of the engine, one of on-period and off-period of the on-off control pulse signal having a predetermined constant value, and supplies the change-over control valve with the control pulse signal. Preferably, a detector is connected to the electronic control unit for detecting a change in the magnitude of a load on the engine and supplying the electronic control unit with an output signal indicative of the detected change in the load magnitude. The electronic control unit is responsive to the output signal for setting the pulse duration of the on-off control pulse signal to a value different from the above predetermined constant pulse duration. A delay valve provided across a passage connecting between the vacuum chamber and the change-over control valve sets the feeding speed of the first control pressure and that of the second control pressure fed through the passage to different values from each other.

摘要： Method for controlling an oxygen concentration sensor for sensing an oxygen concentration in an exhaust gas of an internal combustion engine, which sensor includes an oxygen pump element and a heater element, comprises steps for controlling a pump current and a heat current control in response to a result of a detection of engine load. When the engine is operating in a predetermined high load range, the supply of the pump current to the oxygen pump element is stopped, and the heat current to the heater element is reduced when the engine operation in the high load range has continued for more than a predetermined time period. The heater current to the heater element is stopped when the engine load is in a first predetermined load range, and when the engine operation in a second load range which is lighter than the first load range has continued for a predetermined time period.

摘要： An air intake side secondary air supply system for an internal combustion engine has an air intake system using a carburetor and an air intake side secondary air supply passage leading downstream of the carburetor. The passage includes an oxygen concentration sensor producing an output signal whose level is substantially proportional to an oxygen concentration of the exhaust gas. A control means for controlling a flow control valve is disposed in the air intake side secondary air supply passage and operates in accordance to the output signal of the oxygen concentration sensor. In a variation of the invention, the feedback control of air-fuel ratio using the output signal of the oxygen concentration sensor is effected only when the engine operational state is in a predetermined operational region.
