Understanding your car's engine control unit (ECU)
These days you are new cars equipped with the latest engine technology to find. The engine of the car is a huge change from the carburetor to the ancient right engine control unit (ECU) is submitted. In the 19 th Century, when the first single-cylinder gasoline engine driver of the vehicle entered into force, was the "carburetor" that has emerged. Later, several cylinders were considered to be a new thing. Finally, in the early '80s, we got a new car, consisting of control -Fuel supply, air and spark to the cylinders ICE. It 'was the injection system that was created to replace the old carburetor. In a multi-point fuel injection system, fuel is injected into the cylinders individually. The fuel injection according to the commands of '"on-board engine management" of the computer. This computer is known as the engine control unit or ECU.
The main occupation of the method is based engine control unit (ECU) is the controlthe different functions of an internal combustion engine. Previously, the ECU, which was installed in most cars and sets the parameters of the engine. In addition, the carburetor should determine the amount of fuel per cylinder / per engine cycle. Injected in other words, the simple version of the controller to control only the quantity of fuel into each cylinder is, for each engine cycle. The progressive nature of the engine control unit (ECU), which are installed on most modern cars are able toControl of ignition timing, variable value timing (VVT) and other peripheral devices.
The ECU (engine control unit) controls the engine through sensors, so that it can obtain information about the amount of car fuel, ignition timing and other parameters to be collected. The controller uses the input data received from sensors located in the engine. The various types of sensors that are mounted above the engine, MAP sensor, position sensor, throttle, airTemperature sensor, oxygen sensor and many others. The sensors are integrated into the engine, in principle, the purpose of determining the various "conditions of engine operation and performance. These sensors monitor the various aspects, such as ambient air temperature, engine / coolant temperature , exhaust / main fold-temperature, exhaust O2 content, throttle position, using the engine speed, vehicle speed and engine. The ECU (Engine Control Unit) control method,where you control the output of a system to control the inputs of a system. Since the ECU (engine control unit) collects data from various sensors, he knows all about the temperature of the coolant, the amount of oxygen in the exhaust gases. Based on these existing data, start the ECU (Engine Control Unit) implementing the massive computing per second. Based on the interpretation of all the programmed input data available, the ECU (engine control unit) to the desired positioncontrols used to throttle the engine and power, and thus to help achieve a satisfactory performance of the motor car.
