摘要： A turbocharged engine is provided with a waste gate valve which limits the supercharging pressure in the intake passage downstream of the compressor of the turbocharger not to exceed a predetermined value. The intake passage has first and second pressure propagating paths downstream of the compressor. The pressure wave generated by the intake stroke of the combustion chamber is propagated substantially along the first pressure propagating path when the engine operates at a speed in a low engine speed range under heavy load and substantially along the second pressure propagating path when the engine operates at a speed in a high engine speed range. The part of the intake passage defining the first pressure propagating path is arranged so that a supercharging effect by a kinetic effect of intake air which becomes maximum at a predetermined engine speed in the low engine speed range can be obtained, and the part of the intake passage defining the second pressure propagating path is arranged so that a supercharging effect by a kinetic effect of intake air is better in the high engine speed range when the pressure wave is propagated along the second pressure propagating path than when the pressure wave is propagated along the first pressure propagating path. The predetermined engine speed is lower than an intercept engine speed for the second intake path.
摘要翻译：涡轮增压发动机设置有废气闸阀，其限制在涡轮增压器的压缩机下游的进气通道中的增压压力不超过预定值。进气通道具有压缩机下游的第一和第二压力传播路径。当发动机在重负载下以低发动机转速范围内的速度运行时，并且当发动机运行在基本上沿着第二压力传播路径时，由燃烧室的进气冲程产生的压力波基本上沿着第一压力传播路径传播发动机转速高的速度。限定第一压力传播路径的进气通道的部分被布置成可以获得在低发动机转速范围内以预定发动机转速变为最大的进气的动力学效应的增压效应，并且进气部分通过限定第二压力传播路径的通道被布置成使得当压力波沿着第二压力传播路径传播时，通过进气的动力学效应的增压效应在高的发动机转速范围内比在压力波沿着第二压力传播路径传播时更好第一压力传播路径。预定的发动机速度低于第二进气通道的拦截发动机转速。

摘要： An automobile engine having a device for increasing the inkage air in idle operation when a load is applied to the engine from equipments associate with the engine. An alternator driven by the engine has a voltage regulator which controls the alternator output in response to a load condition on the alternator by controlling the field current. A control unit is provided to restrict an increase in the field current when an electric load is turned on for a time period required for having the engine output increased.
