摘要: The present invention relates to a control apparatus for an internal combustion engine. An object of the present invention is to suppress deterioration of emission and fuel consumption arising during acceleration due to an effect of an exhaust valve opening timing.An upper limit of a fuel injection quantity is set based on the exhaust valve opening timing. The fuel injection quantity is limited to the upper limit or less when the fuel injection quantity is increased during acceleration. The exhaust valve opening timing at which the upper limit is maximized is set to a relatively advanced timing in a low engine speed range, moving in the retard direction as the engine speed rises from the low engine speed range toward a mid engine speed range, and moving in the advance direction as the engine speed rises further from the mid engine speed range toward a high engine speed range.

摘要: A NOx catalyst in the exhaust passage of an internal combustion engine is capable of lean burn and adapted to release and reduce absorbed NOx by a reducing agent. Reducing agent supplier is provided in the exhaust passage on the upstream side of the NOx catalyst. A load detector detects the load of an internal combustion engine. Reducing agent addition controller controls the reducing agent addition period and the reducing agent addition interval based on the load of the internal combustion engine, whereby sufficient reducing agent is supplied to the NOx catalyst side independently of the operating condition.
