摘要： Disclosed is an apparatus for controlling the amount of secondary air fed into an internal combustion engine. This apparatus includes means for causing a sudden change of the level of the absolute pressure signal for driving the secondary air flow control means each time the level of the output voltage of the air-fuel ratio sensor changes. Thus, the equivalent air-fuel ratio is maintained for a long time within a desired range so that the highest purifying efficiency of the three-way catalytic converter can be attained.

摘要： Disclosed is an exhaust gas cleaning apparatus of an internal combustion engine, provided with a three-way catalytic converter, an air-fuel ratio sensor in the form of an oxygen concentration-cell which detects an air-fuel ratio higher than a stoichiometric air-fuel ratio at which the converter effectively operates, and a secondary air injection system adapted for increasing or decreasing the amount of secondary air introduced into the exhaust pipe of the engine in accordance with electrical signals transmitted from the air-fuel ratio sensor. Means are provided for controlling the speed of introduction of secondary air so that the speed of decreasing the amount of secondary air is higher than the speed of increasing the amount of secondary air. Therefore, the air-fuel ratio of the exhaust gas is effectively controlled by signals transmitted from the sensor to approximate the stoichiometric ratio.

摘要： Disclosed is an exhaust gas cleaning apparatus of an internal combustion engine, provided with a three-way catalytic converter, an air-fuel ratio sensor and a secondary air injection system. The secondary air injection system has a diaphragm-operated flow control valve for increasing or decreasing the amount of secondary air introduced into the exhaust manifold of the engine in accordance with electrical signals transmitted from the air-fuel ratio sensor. Means are provided for rapidly increasing or decreasing the air-fuel ratio to a stoichiometric value at the moment when the amount of secondary air passed through the flow control valve is increased or decreased. Therefore, the air-fuel ratio is maintained quite near the stoichiometric value at which the three-way catalytic converter can effectively operate to clean the three major toxic components in the exhaust gas.

摘要： Disclosed herein is a switch device adapted for attaching to a carburetor of an internal combustion engine for detecting a predetermined position of a throttle valve of the carburetor. A lever mechanism which can be moved together with the throttle valve is arranged on the carburetor. The lever mechanism cooperates with a limit switch when the throttle valve is situated at a predetermined position. Thus, an electrical signal indicating the predetermined position is obtained from the limit switch.

摘要： Disclosed is an exhaust gas cleaning apparatus of an internal combustion engine, provided with a three-way catalytic converter and a vacuum-operated flow control valve having a diaphragm for controlling the amount of secondary air directed into an exhaust manifold of the engine for an effective operation of the three-way catalytic converter. The diaphragm operates to increase or decrease the amount of secondary air in accordance with the change of vacuum force on the diaphragm, which force is generated by a vacuum signal transmitted into the valve from an intake manifold of the engine. Means are provided for compensating the difference in the vacuum levels between a high-load condition and a low-load condition so that the rate of increase in the vacuum force of the diaphragm is substantially kept near a constant value for every kind of engine condition. Thus, an ideal operation of the three-way catalytic converter can be obtained.

摘要： Disclosed are an exhaust gas cleaning apparatus of an internal combustion engine, which is provided with a three-way catalytic converter, and an air injection system responsive to the air-fuel ratio of the exhaust gas in the exhaust pipe for increasing or decreasing the amount of secondary air directed to the exhaust pipe so that the air-fuel ratio in the converter is maintained near the stoichiometric value. Means are provided for obtaining a high rate of increase in the introduction of secondary air when the acceleration pump is operated for introducing an amount of excess fuel into the engine during acceleration of the engine. Thus, the air fuel ratio occurring during this condition can be effectively controlled near the stoichiometric value.

摘要： When protective portions are independently provided for each energy generation element, a leakage current inspection between the protective portions and the energy generation elements cannot be performed at once. Therefore, there is a concern that the inspection in manufacturing a substrate for liquid ejection head requires time. Therefore, the substrate for liquid ejection head is manufactured by performing a leakage current inspection between a connecting portion that is electrically connected to plurality of protective portions and a terminal to which the plurality of energy generation elements are connected, and thereafter removing the connecting portion.
