    摘要： A NOx absorbent (18) is disposed in an exhaust passage (17) of an internal combustion engine (1), and a control circuit (30) is provided for controlling the amount of fuel injection into the engine (1). The control circuit 30 works to operate the engine at a rich air-fuel ratio by increasing the amount of fuel supply to the engine so that NOx absorbed by the NOx absorbent when the engine was last stopped is released in all amounts and is purified by reduction after the start of the engine until the engine is first operated at a lean air-fuel ratio. This prevents the release of unpurified NOx from the NOx absorbent (18) at the start of the engine. The operation at a lean air-fuel ratio is assumed in a state where almost no NOx has been absorbed by the NOx absorbent (18), enabling the absorbing capacity of the NOx absorbent to be utilized to the maximum degree.

    摘要： A control system for an internal combustion engine including a direct cylinder fuel injection valve for directly injecting the fuel into a cylinder of an internal combustion engine. The main fuel that burns in the cylinder is injected in the latter half of the compression stroke of the cylinder, and the secondary fuel which is the ineffective fuel that does not burn in the cylinder is injected in the latter half of the exhaust stroke main fuel and the secondary fuel air-fuel ratio mixture around the spark plug. When the secondary fuel is injected, the exhaust valve is opening, and the fuel that is deflected is all discharged out of the cylinder through the exhaust port. Therefore, the ineffective fuel supplied by the secondary fuel injection does not remain in the cylinder, and the output torque does not change in the combustion of the next cycle.

    摘要： Provided is a process for producing pitch carbon fibers by subjecting pitch fibers obtained by melt-spinning a carbonaceous pitch to infusibilization treatment and then to carbonization treatment or both carbonization treatment and subsequent graphitization treatment, characterized in that a dimethyl polysiloxane having a viscosity at 25.degree. C. in the range of 12,000 to 1,000,000 cSt is applied to the fibers after the infusibilization treatment, and the infusibilized fibers with the dimethyl polysiloxane thus applied thereto are then subjected to the carbonization treatment or both the carbonization treatment and the subsequent graphitization treatment.
