These days, you will come by unusual cars with the latest incorporated engine technology. The engine of a car has undergone a massive change, kindly from the age primitive carburetor to the Engine Control Unit (ECU) . In the 19th century, when the first single-cylinder petrol engine driver car came into force, it was the “Carburetor” that came into existence. Later on, multi cylinder engines were considered as a modern thing. Finally, in the early 80′s we got a modern car system, consisting of controlled – feeding of fuel, air and ignition spark to the ICE cylinders. It was the fuel-injection system that was born, which replaced the century venerable carburetors. In a multi point fuel injection system, it injects fuel into individual cylinders. The injection of the fuel takes station on the basis of the commands from the “on board engine management system” computer. This computer is known as the engine control unit or the ECU.
The main process based job of an engine control unit (ECU) is to control the various features of an internal combustion engine’s operation. Earlier, the ECU that was fitted in most of the cars and had their engine parameters fixed. Also, the carburetor would decide the required quantity of fuel per cylinder/per engine cycle. In other words, the simple version of the ECU’S would control only the quantity of fuel injected into each cylinder, at each engine cycle. The advanced types of engine control unit (ECU), which are fitted on most fresh cars, are amazing of controlling the ignition timing, variable value timing (VVT) and other peripherals.
