    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.

    摘要： In a multi-cylinder internal combustion engine including a plurality of fuel injection valves corresponding to a plurality of cylinders, respectively, and a catalytic converter provided in an exhaust system common to the cylinders, the concentration of oxygen in the exhaust gas from the engine is precisely controlled in accordance with the operational condition of the engine in a low-temperature state of the engine for the prompt activation of the catalyst. When the engine is at a low temperature, the operation of the fuel injection valves is controlled so as to stop the supplying of a fuel into the particular cylinders and, the operation of a valve operating characteristic changing means is controlled to adjust the amounts of air drawn and discharged on the basis of conditions detected by operational condition detecting means and at such low temperature to thereby control the oxygen supplied to the catalyst in the catalytic converter whereby the activity of the catalyst can be controlled.
