    摘要: An internal combustion engine includes a direct injector for injecting fuel directly into a combustion chamber of the engine, an intake passage injector for injecting fuel into an intake passage of the engine, and a vaporized fuel processing unit for purging purge gas containing a vaporized fuel into the intake passage. A fuel injection control apparatus includes a detecting section and an injection control section. The detecting section detects the amount of the vaporized fuel in the purge gas. The injection control section changes a fuel injection mode of at least one of the direct injector and the intake passage injector depending on the detected amount of the vaporized fuel. As a result, hampering of engine combustion due to purge gas is suppressed.

    摘要: The invention concerns the generation of homogenous mixtures having a freely selectable composition. The mixture is made using a rotary distribution vessel (1) with its own motor (6) and metered quantities of fuel mixture are introduced into the primary chamber (7) of the vessel via the intake pipe (10) through the metering valve (27), radially distributed by centrifugal force, very finely divided and mixed with air in the mixing chamber (21). The quantitiy and composition of the mixture are adjusted by means of the metering valve (27) in conjunction with the control valve (28) in such a way that the production of the mixture and its conveyance take place at approximately ambient pressure. A motor characteristic establishes the optimum setting for the metering valve and regulating valve for mixture production at approximately ambient pressure while improving fuel consumption and the quality of the exhaust gases. The invention, in connection with the control system described, is especially suitable for the best possible operation of four-stroke engines with lean mixtures at lambda values of at least 1.5 and, in general, 1.8.

    摘要: An internal combustion engine comprises an exhaust purification catalyst. A control system of the engine comprises a downstream side air-fuel ratio sensor at a downstream side of the exhaust purification catalyst, and an air-fuel ratio control device which controls the air-fuel ratio of the exhaust gas. The target air-fuel ratio is set to a lean air-fuel ratio when an output air-fuel ratio of the sensor becomes a rich judged air-fuel ratio or less and is set to a rich air-fuel ratio when an output air-fuel ratio becomes a lean judged air-fuel ratio or more. When the engine operating state is a steady operation state and is a low load operation state, at least one of an average lean degree of the target air-fuel ratio while the target air-fuel ratio is set to a lean air-fuel ratio and an average rich degree of the target air-fuel ratio while the target air-fuel ratio is set to a rich air-fuel ratio is increased.

    摘要: A method of operating a reciprocating internal combustion engine reduces friction power loss in an indicated power to increase net power and to reduce brake specific fuel consumption. A reciprocating internal combustion engine having an output characteristic to generate a maximum indicated power (PM) at a first set engine speed (N1) is provided with a power reducing unit (26). The power reducing unit (26) reduces the output power of the reciprocating internal combustion engine when the engine speed exceeds a second set engine speed lower than the first set engine speed (N2) lower than the first set engine speed (N1) so that the reciprocating internal combustion engine generates a necessary indicate power (PS) at the second set engine speed (N2). A high engine speed range in an engine speed range (R) in which the engine speed of the reciprocating internal combustion engine varies is lower than an engine speed (N3) at which an equivalent conventional reciprocating internal combustion engine generates a necessary indicated power (PS) (Maximum indicated power (Pm). Friction power loss (PL) in an indicated power of the reciprocating internal combustion engine is smaller than that in the same indicated power of the equivalent conventional reciprocating internal combustion engine. So that net power is increased and brake specific fuel consumption is reduced.
