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.
