Understanding Your Car’s Engine Control Unit (ECU)
These days, you will find new cars, acquired the latest engine technology. The engine of a car has undergone a massive change, the ancient right of the carburetor to the Engine Control Unit (ECU). In the 19th Century, when the first single-cylinder petrol engine driver's car came into force, it was the "carburetor that" has emerged. Later, multi-cylinder engines considered a new thing. Finally, in the early 80s we have a new car system,consisting of control – the feeding of fuel, air and spark to the ICE cylinders. It was the fuel injection system that was born, replacing the centuries-old carburetor. In a multi-point injection system, it injects fuel into individual cylinders. The injection of the fuel is made on the basis of commands from the "on-board engine management system computer. This computer is when the engine control unit or ECU known.
The most important process, the job of an engineControl unit (ECU) is to control the various features of the operation of an internal combustion engine. Previously, it was the ECU installed in most cars and they had established with a motor parameter. In addition, the carburetor would determine the required amount of fuel per cylinder / engine per cycle. Injected In other words, the simple version of the ECU to control only the quantity of fuel into each cylinder on each engine cycle. The progressive nature of motor control unit (ECU), which are fitted onMost modern cars are capable of controlling the ignition timing, variable (VVT) and other peripherals.
The ECU (engine control unit) monitors the engine with the help of sensors, so that it can collect information on the amount of cars, fuel, ignition timing and other parameters, such as. The control unit operates on the input data it receives from the various sensors that are inside the machine. The different types of sensors, which are all mounted above the engine, are MAP sensor,Throttle position sensor, air temperature sensor, oxygen sensor and more. The sensors integrated in the engine is normally used to determine the various "operating conditions of the engine and its performance. These sensors monitor the various aspects such as the ambient temperature, engine / coolant temperature, exhaust / main-temp-fold, exhaust O2 content, throttle position, the speed of the engine uses the vehicle speed and crankshaft position. The ECU (Engine Control Unit)Closed-loop control method, in which it monitors the performance of a system to control the inputs to a system. As assembled, the ECU (Engine Control Unit) data from various sensors, knows all about the coolant temperature to the amount of oxygen in the exhaust. On the basis of existing data available, which starts ECU (Engine Control Unit) implementing large calculations per second. On the bases of the programmed interpretation of all available input data, the ECU (Engine ControlUnit) will provide the necessary commands to the engine fuel intake and spark ignition timing system and thus make a contribution to the satisfactory performance of the car's engine.
