469-P1-HI-A20-E 混合气的空燃比对于发动机的动力性
混合气的空燃比对于发动机的动力性、经济性与排放性能有着至关重要的作用。在化油器式发动机中，由多个系统和装置来满足各种工况下的空燃比需求，然而，采用机械的方法，很难做到及时而的空燃比控制。 在大部分现代发动机中，都会采用电控燃油喷射技术，发动机控制器通过一系列传感器取得的读数来决定燃油的喷射量:每个ECU里都会录入一个类似SPM (spark advance map) 的数据表，当传感器监测到engine speed和intake
manifold absolute pressure后会得到相应的需要提前点火的量，通过提前点火让气缸内的燃料充分燃烧。
汽车在使用过程中可能会产生各种各样的故障，这些故障如果不能及时排除，可能会使汽车不能正常使用，甚至会产生很大的安全隐患。现代的配备ECU的汽车有一个基本的功能，就是在汽车某个部件发生故障时，相应的ECU存储器里就自动产生一个故障码，同时在汽车的仪表盘上显示出来，往往是一个汽车保养灯亮起，保持不灭。车主在发现异常后就应该立即前去维修店检查问题并维修。
伍德沃德Woodward TG-13和TG-17是机械液压有差式调速器，用来控制汽轮机-这种不需同步(等速)方式运行的地方。TG-13和TG-17调速器输出轴的大旋转角度为40。从空载到满载推荐的转角行程为调速器全行程的2/3.WOODWARD TG-13E和TG-17E电液执行器均自备立油源，适用于需要无差调速、负荷分配或其他功能的蒸汽透平，并与WOODWARD所有的电子控制器及附件兼容。

The air-fuel ratio of the mixture plays an important role in the power performance, economy and emission performance of the engine. In carburetor engine, there are many systems and devices to meet the requirement of air-fuel ratio under various working conditions. However, it is difficult to achieve timely air-fuel ratio control by mechanical method. In most modern engines, electronic fuel injection technology is used, and the engine controller determines the amount of fuel injected by reading a series of sensors: each ECU enters a data sheet similar to the spark advance map (SPM). When sensors detect engine speed and intake
There is a corresponding amount of pre-ignition required for manifold absolute pressure to fully burn the fuel in the cylinder.
A variety of faults may occur during the use of the car, which, if not eliminated in time, may make the car not normal use, and even cause great security risks. Modern cars equipped with ECU have a basic function, that is, when a certain part of the car fails, the corresponding ECU memory automatically generates a fault code, and it is displayed on the dashboard of the car, often a car maintenance light is turned on and remains on. The owner should immediately go to the repair shop to check the problem and repair after finding an anomaly.
The Woodward TG-13 and TG-17 are mechanical hydraulic differential governors used to control steam turbines – where they operate in a non-synchronous (constant speed) manner. The large rotation Angle of the output shaft of the TG-13 and TG-17 governors is 40. The recommended Angle travel from no-load to full-load is 2/3 of the full range of the governor. The WOODWARD TG-13E and TG-17E electro-hydraulic actuators are self-contained and are suitable for steam turbines requiring differential speed regulation, load distribution or other functions, and are compatible with all WOODWARD electronic controllers and accessories.
