摘要： A catalyzer control apparatus for purifying exhaust gas from an internal combustion engine has an electrically heated catalyzer (2) that is heated by a battery (15) which battery is isolated from the conventionally provided engine battery (4). The temperature of the catalyzer (2) is detected by a sensor (6) and a control circuit (12) located with an engine control unit (5) selectively applies power to heat the catalyzer (2). The catalyzer (2) is arranged to be pre-heated prior to engine start and by isolating the battery for heating the catalyzer from the normally provided engine battery so, because the catalyzer (2) takes a great power, engine starting is enhanced by virtue of having separate batteries (15, 4).

摘要： A voltage regulator for a charging generator is disclosed which comprises an a.c. generator having armature windings (1) and a field winding (2), and a battery (9) which receives the rectified output of the a.c. generator and is charged by the same. The voltage regulator (6) regulates the output voltage of the a.c. generator by controlling the current flowing through the field winding (2). To prevent the output voltage of the a.c. generator from becoming a high voltage when a connecting wire connecting the rectified output of the a.c. generator to the battery is broken, the regulator includes also abnormality detection means (30, 50) which compares the rectified output (V L ) of the a.c. generator with the battery voltage (V s ) and detects the abnormality when both voltages are different by more than a predetemined value. This arrangement makes it possible to detect the abnormality at the point of time where the output voltage of the a.c. generator is not yet much high.
