带断电器的电力起动机电路

现行电力起动机没有断电器，这在起动机无法退出起动时易将起动机烧毁。本文以ＳＴ６１４ 型起动机为例，设计了带断电器的两个起动机电路。实验表明，带断电器的起动机不仅其主触头使用寿命大大延长，而且在无法退出起动的故障状态下可同时使自身核心部件及蓄电池均得到有效保护。

浅谈现代车用起动机

1起动机功用 汽车发动机是靠外力起动的，起动时必须依靠外力使曲轴旋转，并要求曲轴的旋转达到一定的转速，才能起动内燃机。汽车发动机常用的起动方式有人力起动和电力起动机起动。

运七飞机发动机电力起动过程分析

通过对运七飞机发动机起动过程的分析,阐述了飞机在起动中的4级过程:转子回路传入电阻RST,电枢串联电阻起动;切除电阻RST,起动发电机增速;两组电瓶串联升压;切除并励绕组成串联电动机工作,使发动机起动顺利完成。掌握飞机发动机的起动过程,对从事飞机制造的调试和维修人员有一定的借鉴和帮助作用。

东风EQ1118GA柴油车起动机不运转故障诊断与排除

汽车发动机的起动必须借助外力带动曲轴转动来实现。过去有些车辆采用人力起动的方式来起动发动机,人力起动费时费力且不安全,因此,很快就被电力起动机所代替。电力起动机结构简单、起动迅速、操作安全方便,在现代汽车上得到了普遍采用。汽车在使用一段时间后,会由于某些原因,造成将点火时起动机不运转,该故障产生后将直接导致发动机无法正常起动,

汽车电气系统故障的检测

电源低压直流汽车电源系统主要由蓄电池、发电机、电压调节器等电气设备组成。其特点：一是低压。汽车电源系统的额定电压主要有12伏和24伏2种。汽油车普遍采用12伏电源；柴油车多采用24伏电源，通常由2个12伏蓄电池串联而成。汽车运行时的电压，12伏电源系统为13．5～14．5伏，24伏电源系统为27～28伏。二是直流。现代汽车发动机是靠电力起动机启动的，起动机由蓄电池供电，而向蓄电池充电又必须用直流电源，所以汽车电源系统为直流系统。

Torque Distribution Strategy for Integrated Starter/ Generator Hybrid Bus Implemented by Fuzzy Algorithm

A torque distribution strategy was designed by using fuzzy logic to realize the optimal control. The vehicle load zones were dynamically divided into several zones by several torque lines to indicate the drivers demand and the high or low efficient operating areas of the diesel engine. The fuzzy logic controller with trapezoid membership function and Mamdani rule reference mechanism was utilized. There are over 100 rules used in this fuzzy-based torque distribution strategy which are sorted into four rule-bases. The fuel economy and acceleration tests were designed to test and validate the integrated starter/generator (ISG) bus perfor-mance using fuzzy-based torque distribution strategy. The fuel economy is improved 7.7% compared with the rule-based strategy. Finally the road test results reveal that there is about 15% improvement of fuel economy. And the 0-50 km/h acceleration time is 9.5% shorter than the original bus.
