英语翻译
As against an inlet manifold engine of the same power,the turbo engine requires a smaller installation space and as such has a better power-weight ratio.
The exhaust turbo-charger has,as its main parts,a compressor and an exhaust turbine,whose gears are fitted on to a common shaft.
The exhaust turbine converts a part of its exhaust energy into rotational energy and drives the compressor.This sucks fresh air and supplies the pre-compressed air through turbo-air cooler,throttle valve and inlet manifold to engine.
Positioning element for exhaust turbo-charging.
The petrol engine has,due to its throttled air intake,a large range of variation in exhaust mass flow compared to the Diesel engine.An optimal adaptation of the exhaust turbine is possible only for a limited range.Passenger car engines must reach a high torque even at low speeds.Therefore the turbine housing is designed for a small exhaust mass flow,e.g.,full load at n = 2000 min-1.
In order that exhaust turbo-charger does not now overload the engine,in the event of large flows of exhaust mass,a part of this flow in this range must be taken past the turbine through a bypass valve (“Waste gate”) to the exhaust system.Usually,this bypass valve is integrated in the turbine housing as butterfly valve.Use of poppet valve in a separate housing parallel to turbine is seldom.
Electronic supercharging pressure regulation
In a pneumatic-mechanical regulation,the positioning element of turbo-charger is directly exposed to the supercharging pressure from compressor outlet.Hereby,the torque-characteristics over engine speed can be selected only in very narrow limits.There is only one full load limit over the load.The tolerances can not be regulated as for degree of supercharging at full load.In part loads the closed bypass valve worsens the efficiency.Acceleration from low engine speed can lead to a delayed response of exhaust turbocharger (conspicuous “hole in turbo-charge”.

纯手工翻译,质量保证.
As against an inlet manifold engine of the same power, the turbo engine requires a smaller installation space and as such has a better power-weight ratio.
与相同功率的进气歧管发动机的相比,涡轮增压发动机需要相对较小的安装空间,同时也具有较好的功率重量比.
The exhaust turbo-charger has, as its main parts, a compressor and an exhaust turbine, whose gears are fitted on to a common shaft.
排气涡轮增压器的主要部件包括压缩机和排气涡轮,此二者的齿轮上被安装在一个共同的轴上.
The exhaust turbine converts a part of its exhaust energy into rotational energy and drives the compressor. This sucks fresh air and supplies the pre-compressed air through turbo-air cooler, throttle valve and inlet manifold to engine.
排气涡轮将排出的能量转化为旋转动能,并以此驱动压缩机.这样一来可以吸入新空气,并能将其预压缩,依次通过增压空气冷却器、节流阀和进气歧管,最终供给发动机.
Positioning element for exhaust turbo-charging.
排气涡轮的定位元件
The petrol engine has, due to its throttled air intake, a large range of variation in exhaust mass flow compared to the Diesel engine. An optimal adaptation of the exhaust turbine is possible only for a limited range. Passenger car engines must reach a high torque even at low speeds. Therefore the turbine housing is designed for a small exhaust mass flow, e.g., full load at n = 2000 min-1.
由于进气口的限流,相比柴油发动机,汽油发动机的排气流量有大范围的变化.最佳的排气涡轮可能仅适有限的范围.轿车发动机必须达到低转速下的高扭矩.因此,涡轮增压器是专为小排气流量设计的,例如满负荷时,转速2000 min - 1.
In order that exhaust turbo-charger does not now overload the engine, in the event of large flows of exhaust mass, a part of this flow in this range must be taken past the turbine through a bypass valve (“Waste gate”) to the exhaust system. Usually, this bypass valve is integrated in the turbine housing as butterfly valve. Use of poppet valve in a separate housing parallel to turbine is seldom.
为了防止废气不使发动机超载,在大量气体流经时,一部分气流,必须通过旁通阀(“废门”)流出.通常,该旁路阀集成在蝶阀涡轮作为外壳存在.很少有作为单独的外壳,而与水轮机并行的情况.
Electronic supercharging pressure regulation
电子增压调节
In a pneumatic-mechanical regulation, the positioning element of turbo-charger is directly exposed to the supercharging pressure from compressor outlet. Hereby, the torque-characteristics over engine speed can be selected only in very narrow limits. There is only one full load limit over the load. The tolerances can not be regulated as for degree of supercharging at full load. In part loads the closed bypass valve worsens the efficiency. Acceleration from low engine speed can lead to a delayed response of exhaust turbocharger (conspicuous “hole in turbo-charge”.
在气动机械调节中,涡轮增压器的定位元件会直接暴露在压缩机出口的巨大气压下,在这种情况下,发动机的扭矩特性只能在很窄的范围内选择.我们知道,满载时只能有一个满载极限.在满载的时候,偏差不能在增压中进行调节.因此,随着旁通阀关闭,部分负载的效率也随之降低.所以说,低转速发动机的加速可能导致废气涡轮增压器延迟反应(被称为,充电的空穴).
