    摘要: A system for controlling fuel injection in an internal combustion engine such that when the target air-fuel ratio is switched from a rich value to a lean value, the air-fuel ratios are switched to the lean value by sequentially decreasing the amount of fuel injected into the cylinders, for example in a four cylinder engine into the #1, #2, #3 and #4 cylinders, with predetermined time differences. During this time, an electronic air control valve (EACV) is controlled in such a manner that it is stepwise opened with the switching of the air-fuel ratio s for the #1, #2, #3 and #4 cylinders, thereby causing the engine torque to remain the same to prevent the generation of a torque shock. When the target air-fuel ratio has been switched from the lean level to the rich level, the amounts of fuel injected into the #1, #2, #3 and #4 cylinders are controlled in such a manner that they are sequentially increased with predetermined time differences, and the EACV is controlled in such a manner that it is stepwise closed. Thus, it is possible to avoid the generation of a torque shock, while preventing the degradation of the emission during switching of the air-fuel ratio.

    摘要: An apparatus for controlling hydraulic pumps for a construction machine wherein the construction machine includes first and second hydraulic pumps adapted to be driven by an engine and hydraulic actuators hydraulically connected to the first and second hydraulic pumps via first and second actuating valves is disclosed. A controlling section calculates extra horse powers .DELTA.HP.sub.1 and .DELTA.HP.sub.2 based on reference allowable absorptive horse powers set relative to the first and second hydraulic pumps and actual absorptive horse powers (HP.sub.01) and (HP.sub.02) derived from the first and second hydraulic pumps. In addition, the controlling section calculates allowable discharge capacities (V.sub.1P) and (V.sub.2P) based on the number (N) of revolutions of the engines, pressures (P.sub.1) and (P.sub.2) of hydraulic oils discharged from the first and second hydraulic pumps, the extra horse powers .DELTA.HP.sub.1 and .DELTA.HP.sub.2 and allowable discharge capacities (V.sub.1P) and (V.sub.2P). Then, the controlling section selects a smaller one of a target discharge capacity and the allowable discharge capacity (V.sub.1P) and a smaller one of another target discharge capacity and the allowable discharge capacity (V.sub.2P) as minimum target discharge capacities (V.sub.1) and (V.sub.2). Thereafter, the controlling section controls swash plate angles of the first and second hydraulic pumps such that the minimum target discharge capacities (V.sub.1) and (V.sub.2) are correctly set corresponding to the first and second hydraulic pumps. Consequently, absorptive horse powers to be derived from the first and second hydraulic pumps can properly be controlled while a sum of the reference allowable absorptive horse powers is kept constant.
