What is an actuator used in an automotive electronic engine for?

An actuator is an element of an electronic control system. The various control functions to be completed by the electronic control system are realized by various actuators. In the control process, the actuator converts the control signal from the ECU into a certain mechanical motion or electrical movement, thereby causing the change of engine operating parameters and completing the control function.

The actuators in the engine electronic control system include: fuel injector, electronic throttle body, electronic independent ignition system, electric fuel pump, etc., which are all based on the engine control unit instructions to work under various working conditions.

Sensors include: inlet air temperature and pressure sensor, water temperature sensor, knock sensor, throttle position sensor, oxygen sensor, camshaft position sensor or crankshaft position sensor or both.

The engine electronic control system (EECS) is to make the engine work under the best working conditions through the electronic control of engine ignition, fuel injection, air to fuel ratio, exhaust emissions, etc., so as to improve the performance of the whole vehicle, save energy and reduce exhaust emissions.

It should be an electronic actuator in the engine. It is a part that completes the driving computer and controls the instructions to realize the specific control action.

Perform the tasks specified by the electronic control unit to complete the specific control actions. It's like a human hand or foot.

The incidence of engine failure is greatly reduced. With the development of automotive electronics, the higher the automation, the greater the dependence on sensor actuators.

It's okay, this dream may not be too good, if you dream of an actuator in a car's electronic engine, it means that you may be unlucky recently.

The electronically controlled gasoline injection system includes the following three subsystems: 1. Fuel ** system, air intake system and electronic control system; 2. The fuel system is composed of a gasoline tank, a fuel pump, a gasoline filter, a pressure regulator, a pulsating attenuator, an injector, an oil pipe, an oil return pipe, etc.; 3. The air intake system consists of an air filter, a throttle valve, an air flow meter, an air intake chamber, an idle control valve and an air intake control valve; 4. The function of the fuel ** system and the air intake system is to mix the fuel injection volume and air intake volume determined by the ECM ECU into a combustible mixture according to the throttle position (engine load) and engine speed, and enter the cylinder for combustion work; 5. The electronic control system is composed of a number of sensors that only detect various conditions of the engine, an ECU that determines the amount of fuel injection according to the sensor signal, and an injector that works according to the ECU instructions, and its main role is to determine the best injection timing and injection duration according to different working conditions of the engine. Actuator:

Idle control valve, fuel injector. Intake pressure and air flow meters monitor engine air intake to control fuel injection. The throttle position sensor detects the angle at which the throttle is opened to control the basic amount of fuel injected.

The water temperature sensor is the main signal when it is activated, and when other signals are generated, it is the signal to correct the amount of fuel injected. The crankshaft position sensor detects the engine speed and angle to control the injection pulse width and ignition time.

Fuel injectors, igniters, idle control valves, cruise control solenoid valves, throttle control motors, EGR valves, intake control valves, secondary air injection valves, activated carbon tank excretion solenoid valves, oil pump relays, fan relays, air conditioning compressor relays, self-diagnostic display and alarm devices, instrument displays, etc.

Actuators are an essential and important part of an automatic control system. Its function is to accept the control signal sent by the controller and change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. Actuators can be divided into three categories: pneumatic, hydraulic and electric according to their energy form.

Pneumatic actuators use compressed air as an energy source, which is characterized by simple structure, reliable action, stable action, large output thrust, convenient maintenance, fire and explosion protection, and low quality, so it is widely used in chemical, papermaking, oil refining and other production processes, it can be easily used with passive instruments.

Even when using an electric meter or computer control, pneumatic actuators can still be used as long as the electrical signal is converted to a standard barometric pressure signal of 20-100 kPa by an electric-pneumatic converter or electro-pneumatic valve positioner.

The energy of the electric actuator is easy to use and the signal is transmitted quickly, but the structure is complex and the explosion-proof performance is poor. Hydraulic actuators are basically not used in the production process of chemical industry, oil refining, etc., and it is characterized by a large output thrust.

1.The main actuators on the automobile engine are cylinders, pistons, connecting rods, and crankshaft flywheel mechanisms.

2.An engine is a machine that converts a certain form of energy into mechanical energy. Its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power.

The power of the car comes from the engine. According to the different fuels used, common engines can be divided into gasoline engines (referred to as gasoline engines) and diesel engines (referred to as diesel engines). Gasoline engines are fueled by gasoline, and diesel engines are fueled by diesel.

The automotive electronic control system consists of two parts: hardware and software. Automotive electronic control is the automotive electronic control system, which is basically composed of sensors, electronic controllers (ECUs), drivers and control program software, etc., which are used in conjunction with the mechanical system on the car, and use cables or radio waves to transmit information to each other for "mechatronic integration".

Electronic control system.

The application control device automatically and purposefully controls and operates a machine or process to give it a certain state and performance. The automatic control system is generally composed of several parts, such as detection and feedback unit, instruction and signal processing unit, conversion and amplification unit, actuator and power source.

From the perspective of control principle, the automotive electronic control system can be simplified into three components: sensor, ECU and actuator. Sensors are components that perceive information and provide ECUs with information such as vehicle health and engine conditions. The ECU receives the information from the sensor, processes the information and sends the corresponding control command to the actuator.

The actuator converts the control signal from the ECU of the trip computer into some kind of mechanical movement.

or the movement of electrical appliances, thereby causing the change of engine operating parameters, to complete the closed guess control function.

Actuators mainly include electromagnetic injectors, ignition controllers (ignition modules), idle control valves or idle control motors, Douzhou EGR valves, air intake control valves, secondary air injection valves, activated carbon tank solenoid valves, vehicle speed control solenoid valves, fuel pump relays, cooling fan relays, and air conditioning compressors.

Relays, automatic transmissions.

Gear solenoid valve, pressure relief solenoid valve of pressure booster, self-diagnosis and alarm device, fault backup program start device, instrument vacancy shield display, etc. As the control function increases, so does the type and number of actuators.

Hello, in other words, your hand is equivalent to an actuator.
