What is the core of an engine control system?

Hello, for the problems you encounter, I am happy to help you, I have encountered yo before, the following is my personal opinion, I hope to help you, if there is a mistake, I hope to forgive me!.

Automotive electronic control systems are basically composed of sensors, electronic controllers (ECUs), and drivers.

The core component is the electronic controller.

Works with the mechanical systems on the vehicle (typically with the powertrain, chassis system, and body system.)

in the fusion of subsystems) and utilize cable or radio waves.

The transmission of information to each other, the so-called "mechatronics", such as electronic fuel injection systems, anti-lock braking control systems, anti-skid control systems, electronically controlled suspension systems, electronically controlled automatic transmissions.

electronic power steering, etc.

The electronically controlled ignition device consists of a microprocessor, a sensor and its interface, an actuator, etc. The device calculates and judges according to the engine parameters measured by the sensor, and then adjusts the ignition time, which can make the engine work at the best ignition advance angle under the conditions of different speeds and air intake, so that the engine outputs the maximum power and torque, reduces fuel consumption and emissions, saves fuel and reduces air pollution.

Extended Materials. With the integration of control technology, computer technology.

and the development of network technology, automotive electronics technology has obviously developed in three main directions: integration, intelligence and networking.

1) Integration.

Embedded systems in recent years.

The maturity of LAN control and data bus technology makes the integration of automotive electronic control systems an inevitable trend in the development of automotive technology. The engine management system and automatic transmission control system are integrated into the integrated control of the drivetrain. Thank you very much for your patience** and have a great day if it helps! Thank you!

The electronic control unit is the heart of the engine control system.

The engine control system is mainly composed of three parts: electronic control unit ECU, sensors and actuators.

The basic composition of the mu family of the electronic control system.

Signal input device: a variety of sensors, collect the signals required by the control system, and convert them into electrical signals and transmit them to the ECU through the line.

Electronic control unit (ECU): provides a reference (reference) voltage to each sensor, receives the electrical signal input from the sensor or other device, and stores, calculates, analyzes, and processes the received signal before issuing instructions to the actuator.

Actuator: A device controlled by an ECU that performs a specific control function.

The basic functions of the electronic control unit (ECU) nuclear base:

1. Provide a standard voltage to the sensor, accept the input information of various sensors and other devices, and convert it into a digital signal that can be accepted by a microcomputer.

2. Store the characteristic parameters of the vehicle model and the relevant data information required for the calculation.

3. Determine the program required to calculate the output instruction, and calculate the output instruction value according to the input signal and related programs.

4. Compare the input signal and output command signal with the standard value, determine and store the fault information.

5 Output commands to the actuator, or output its own stored information according to the instructions.

6 Self-correction function (learning function).

The automobile engine is composed of five major systems and two major mechanisms, the two major mechanisms are the crank connecting rod mechanism and the valve mechanism. The five major systems are the fuel supply system, the cooling system, the lubrication system, the ignition system, and the starting system.

The engine is not integrated, the engine has valve chamber covers, cylinder heads, buried pants cylinder blocks, oil pans from top to bottom, and there are gaskets between these parts.

Inside the engine there are connecting rods, pistons, crankshafts, valves, camshafts, balance shafts, etc.

The engine is known as the heart of the car, and the engine is responsible for powering the car.

In the car, there is another very important component, and that is the gearbox. The gearbox plays the role of variable speed and torque, the gearbox belongs to the transmission system, the gearbox can transmit the power generated by the automobile engine to the wheels, and the power output of the gearbox after changing the speed and torque can meet the needs of the car in various working conditions.

There are many types of automobile engine cylinders, such as inline cylinders, V-cylinders, W-cylinders, horizontally opposed bending cylinders, etc.

Most common family cars are equipped with in-line four-cylinder engines, some high-performance cars are equipped with V-cylinder engines, and some brands use horizontally opposed cylinder engines.

The engine control system basically consists of three parts:

Signal input closed-rise and open-door device: a variety of sensors to collect the signals required by the control system.

Electronic control unit: provide reference voltage to each sensor, accept the input electrical signal of the sensor or other devices of the car, and send instructions to the actuator after storing, calculating, analyzing and processing the received signal.

Actuator: A device controlled by ECU that performs a control function.

The engine control system is mainly composed of three parts: electronic control unit ECU, sensor and actuator. Signal transmission and embedding device: various sensors collect the signals required by the control system and convert them into electrical signals and transmit them to the ECU through the line.

Electronic control unit (ECU): provides a reference (reference) voltage to each sensor, receives the electrical signal input from the sensor or other device, and stores, calculates, analyzes, and processes the received signal.

The gasoline engine is composed of two major mechanisms and five major systems, namely, the crank connecting rod mechanism, the gas distribution mechanism, the fuel supply system, the lubrication system, the cooling system, the ignition system and the starting system;

The diesel engine is composed of two major mechanisms and four major systems, namely the crank connecting rod mechanism, the gas distribution mechanism, the fuel supply system, the lubrication system, the cooling system and the starting system.

1. Crank connecting rod mechanism.

The crank linkage mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion, which is composed of the body group, the piston connecting rod group and the crankshaft flywheel group.

2. Gas distribution mechanism.

The function of the valve mechanism is to open and close the intake and exhaust valves at regular intervals according to the working sequence and working process of the engine, so that the combustible mixture or air enters the cylinder, and the exhaust gas is discharged from the cylinder to realize the ventilation process.

3. Cooling system.

The function of the cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature state.

4. Fuel supply system.

The function of the gasoline engine fuel supply system is to prepare a certain amount and concentration of mixed gas according to the requirements of the engine, enter the cylinder, and discharge the exhaust gas after combustion from the cylinder to the atmosphere;

The function of the diesel engine fuel supply system is to enter the cylinder separately for diesel and air, form a mixture in the combustion chamber and burn, and finally discharge the exhaust gas after combustion.

5. Lubrication system.

The function of the lubrication system is to deliver a certain amount of clean lubricating oil to the surface of the parts that are moving relatively, reduce the frictional resistance, reduce the wear of the parts, and clean and cool the surface of the parts.

6, Ignition system.

In a gasoline engine, the flammable mixture in the cylinder is ignited by an electric spark, for which a spark plug is installed on the cylinder head of the gasoline engine, and the head of the spark plug protrudes into the combustion chamber. All equipment that can generate electric sparks between the spark plug electrodes on time is called an ignition system, and the ignition system usually consists of a battery, a generator, a distributor, an ignition coil, and a spark plug.

7. Starting system and charging system.

The starting system consists of a battery, an ignition switch, a starting relay, a starter, etc. The function of the starting system is to convert the electrical energy of the battery into mechanical energy through the starter to start the engine. The charging system consists of a generator, a regulator, a battery and a charging indicator, which is the power supply for the electrical equipment of the car.

The two major mechanisms are the crank, connecting rod mechanism, and the gas distribution mechanism.

The five major systems are cooling system, starting system, ignition system, lubrication system, and fuel supply system.

Hello, the two major mechanisms are divided into a valve mechanism and a crank connecting rod mechanism. The system is divided into cooling system and lubrication system. Ignition system, starting system. There is also an air supply system. Hope my answer can help you.
