    摘要： A system for reducing the hydrocarbon content of engine exhaust gases emitted during deceleration of an automobile by controlling both the air-fuel ratio of the engine fuel mixture and the intake manifold vacuum which increases rapidly as soon as the automobile starts to slow down, said air-fuel ratio and intake manifold vacuum being controlled by supplying air to the intake manifold of the engine by way of the step mixture supply flow path of the secondary side of a carburetor of compound-type, which path is kept substantially inoperative during the deceleration of the automobile.

    摘要： Improvements are made in an automotive internal combustion engine equipped with a thermal reactor, a catalytic converter or a combination of these so as to enable the thermal reactor and/or the catalytic converter to reach its activation temperature in a shortened period of time after the engine has initially been cranked by a cranking motor whereby toxic combustible residues can be re-oxidized at an early stage of the idling operation of the engine. The improvements consist of an exhaust recirculation passageway which is made operative to recirculate the exhaust gases from the engine for warming up an air-fuel mixture to be fed to the engine when the temperature of the exhaust gases is lower than an activation temperature of the thermal reactor or the catalytic converter. Such improvements will be more advantageous when combined with a rapid engine warming arrangement for opening a carburetor throttle valve wider than usual and providing retarded spark-advance timings during cold driving of the engine.

    摘要： A misfiring detector for detecting a misfire occurring in an internal combustion engine which comprises a gas current pulse generator which has electrodes forming an ion-gap for generating gas current pulse signal when a high temperature burned gas is emitted through the ion-gap from the engine, an engine speed sensor for generating an engine speed pulse signal with a repetition rate proportional to the speed of the engine, and an electronic computing means responsive to the gas current pulse signal and the engine speed pulse signal to produce an electric output signal representing the occurrence of the misfire when the ratio of the number of the gas current pulse signal to that of the engine speed pulse signal is less than a predetermined value. The gas current pulse generator is disposed in an exhaust manifold in the vicinity of an exhaust port as adjacently as possible. The misfiring detector further comprises an indicator for indicating the occurrence of the misfire and a storing means for storing the misfiring condition. Furthermore, disclosed herein is a protection system for preventing an exhaust gas purifying means from being destroyed by unburned gas caused by the misfire through utilization of the above misfiring detector. The protection is accomplished by shutting off the unburned gas and/or a secondary air drawn into the exhaust gas purifying means in the event that the misfire occurs in the engine, or by controlling an amount of the secondary air.

    摘要： First and second temperature detectors respectively detect the temperatures of the exhaust gases in a vehicle exhaust system catalytic inlet and outlet ports of the converter. A first comparator produces a operating temperature signal when the voltage of the inlet temperature signal from the first temperature detector exceeds a first predetermined level. A difference signal generator produces a difference signal representing the difference of the inlet and outlet temperatures of the converter in accordance with the inlet and outlet temperature signals from the detectors, a second comparator produces a degradation signal when the voltage of the difference signal is lower than a second predetermined level, an AND gate produces an alarm signal when the pedestal and degradation signals are applied thereto. An alarm device provides an indication when the alarm signal is applied thereto.
