摘要： An air pump abnormality-detecting system for an internal combustion engine. The engine has a catalyst arranged in the exhaust system of the engine, a passage extending from the exhaust system at a location upstream of the catalyst, and an electrically driven air pump arranged across the passage, for supplying secondary air into the exhaust system. A current sensor detects electric current flowing through the air pump, and a voltage sensor detects voltage applied to the air pump. An abnormality of the air pump is detected by comparing an output from the current sensor obtained during operation of the air pump, with predetermined abnormality-detecting reference values. At least one of the output from the current sensor or the predetermined abnormality-detecting reference values is corrected in response to an output from the voltage sensor.

摘要： A control system controls an electrically heated catalyst for purifying exhaust gases emitted from an internal combustion engine. Voltage applied to the electrically heated catalyst and electric current flowing through the same are detected. A changeover is made between supply and interrupt of power to the electrically heated catalyst. A parameter indicative of an operative state of the electrically heated catalyst is calculated based on the detected voltage and the detected current, and the operative state of the electrically heated catalyst is detected based on the parameter. The changeover between the supply and interrupt of power to the electrically heated catalyst is controlled based the operative state of the electrically heated catalyst thus detected.

摘要： A failure detection system detects a failure occurring in an exhaust secondary air supply system of an internal combustion engine, and has a catalytic converter installed in an exhaust pipe of an exhaust system of the engine for reducing pollutants from exhaust gases emitted from the engine, a conduit connected, at one end, to the exhaust pipe at a location upstream of the catalytic converter and an air pump connected to an opposite end of the conduit for supplying compressed air in the conduit. The conduit is closed by the a valve which opens in response to the negative pressure and a second valve which opens in response to the conduit pressure. In the system a first prescribed level and the second prescribed level are set and two pressure switches are provided for generating output at the levels. A failure occurring in the air pump and the valve is detected based on operation of the air pump and the output of the pressure detectors. Alternatively, the failure is detected by changing the timing of the termination of the air pump and closing of the second valve while using one switch and the second prescribed level. The system is simple in configuration.

摘要： A heat-insulating, light and vibration-proof exhaust manifold for a multi-cylinder internal combustion engine is provided. The exhaust manifold comprises an upper stream flange, a lower stream flange, four manifold pipes at an upper stream, a manifold chamber (gathering section) at a lower stream and a manifold case of a plate metal covering the manifold pipes and the manifold chamber. The manifold pipes have upper stream ends to be connected to exhaust ports of the internal combustion engine through the upper stream flange and lower stream ends gathering in the manifold chamber. Upper stream ends of the manifold pipes and the manifold case are welded to the upper stream flange, and lower stream ends of the manifold chamber and the manifold case are welded to the lower stream flange. The manifold pipe and the manifold chamber can slide relatively at a slide portion which is maintained by pressing the manifold chamber and the manifold case against the manifold pipe.

摘要： An exhaust manifold M is comprised of a plurality of inner exhaust pipe shells secured to an upper flange, and a plurality of outer exhaust pipe shells secured to the upper flange to individually cover the inner exhaust pipe shells, wherein a downstream end of each of the corresponding inner exhaust pipe shells slidably contacts an annular bead bulging from an outer peripheral surface of the downstream end of the outer exhaust pipe shells. An inner collecting pipe shell communicates with the plurality of inner exhaust pipe shells and is secured at its upstream end to the plurality of outer exhaust pipe shells, and an outer collecting pipe shell which is secured at its upstream end to the plurality of outer exhaust pipe shells covers the inner collecting pipe shell. A downstream end of the inner collecting pipe shell slidably contacts an annular mesh member interposed therebetween. Sliding portions for absorbing a difference in the axial thermal elongation between inner and outer double walls are provided separately at the downstream end of an exhaust single pipe and the downstream end of an exhaust collecting pipe. Thus, the sliding stroke in each of the sliding portions can be set to a small value, and the absorption of the thermal elongation can be carried out smoothly.
