建议机的增压系统就是为了改善燃油的经济性,增加循环供油量,建议机在轿车的里面占据重要的方位,今日小编就要给大家先容一下建议机增压系统类型。
The supercharging system of the recommender is to improve the fuel economy and increase the cycle fuel supply. The recommender occupies an important position in the car. Today's edition will introduce the type of the supercharging system of the recommender to us.
建议机增压系统类型:机械增压
Suggested type of turbocharging system: mechanical turbocharging
结构:机械增压器由建议机曲轴经齿轮增速器驱动,或由曲轴齿形传动带轮经齿形传动带及电磁离合器驱动
Structure: The mechanical supercharger is driven by the crankshaft of the recommender through the gear accelerator, or by the crankshaft tooth drive pulley through the tooth drive belt and electromagnetic clutch.
特色:机械增压能有效地前进建议机功率,与涡轮增压比较,其低速增压效果更好。另外,机械增压器与建议机简略匹配,结构也比较紧凑。但是,因为驱动增压器需耗费建议机功率,因此燃油耗费率比非增压建议机略高。
Features: Mechanical turbocharging can effectively advance the recommended engine power. Compared with turbocharging, its low-speed turbocharging effect is better. In addition, the mechanical supercharger and the proposed machine are simply matched, and the structure is relatively compact. However, the fuel consumption rate is slightly higher than that of the non-turbocharger recommender because it consumes the recommended engine power to drive the turbocharger.

建议机增压系统类型:气波增压
Suggested type of turbocharging system: gas wave turbocharging
结构:由曲轴经传动带驱动气波增压器转子,运用排气压力波使空气遭到紧缩,以前进进气压力。
Structure: The crankshaft drives the air wave supercharger rotor through the drive belt. The exhaust pressure wave is used to compress the air, and the inlet pressure is used before.
特色:气波增压器结构简略,加工便利,作业温度不高,不需要耐热资料,也无需冷却。与涡轮增压比较,其低速转矩特性好,但是体积大,噪声水平高,安装方位遭到必定的束缚。这种增压器还只能在低速范围内运用。因为柴油机高转速比较低,因此多用于柴油机上。
Features: The structure of the gas wave supercharger is simple, easy to process, low operating temperature, no heat-resistant data, no cooling. Compared with turbocharging, its low-speed torque characteristics are good, but its volume is large, noise level is high, and installation orientation is bound by certain constraints. The supercharger can only be used in a low speed range. Because the highest speed of diesel engine is relatively low, it is mostly used in diesel engine.
建议机增压系统类型:涡轮增压
Suggested type of turbocharging system: turbocharging
结构:运用废气涡轮机,带动与其同轴安装的压气机叶轮作业,新鲜空气在压气机内增压后进入气缸
Structure: Use exhaust gas turbine to drive the operation of compressor impeller installed in coaxial with it. Fresh air enters the cylinder after pressurizing in the compressor.
特色:涡轮增压的利益是经济性比机械增压和非增压建议机都好,并可大幅度地下降有害气体的排放和噪声水平。涡轮增压的缺陷是低速时转矩增加不多,并且在建议机工况发生变化时,瞬态照应差,致使轿车加快性,特别是低速加快性较差
Features: Turbocharger benefits are better economy than mechanical and non-turbocharging recommenders, and can significantly reduce the emission of harmful gases and noise levels. The disadvantage of turbocharging is that the torque increases little at low speed, and the transient response is poor when the recommended engine operating conditions change, resulting in poor acceleration of the car, especially at low speed.
建议机增压系统类型:复合增压
Suggested Type of Turbocharger System: Compound Turbocharger
结构:机械增压与涡轮增压恰当结合
Structure: Proper combination of mechanical turbocharging and turbocharging
串联复合增压:在这种增压系统中,空气先经涡轮增压器前进压力后,进人中间冷却器降温,再经机械增压器增压。这种增压方法首要用于高增压建议机上
Series compound turbocharging: In this turbocharger system, air is first pressurized by the turbocharger, then cooled by the intermediate cooler, and then pressurized by the mechanical turbocharger. This pressurization method is mainly used in the high-pressure recommendation machine.
并联复合增压:由机械增压器和涡轮增压器一同向建议机供应增压空气。在低转速范围首要靠机械增压,而在高转速范围首要靠涡轮增压。这种增压系统使建议机低速转矩特性得到改善
Parallel compound supercharger: Supercharged air is supplied to the recommender by mechanical supercharger and turbocharger together. Mechanical turbocharging is the primary method in the low speed range, while turbocharging is the primary method in the high speed range. This turbocharging system improves the low-speed torque characteristics of the proposed engine.
