ng of fuel, air and ignition spark to the ICE cylinders. It was the fuel-injection system that was born, which replaced the century old carburetors. In a multi point fuel injection system, it injects fuel into individual cylinders. The injection of the fuel takes place 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 [link widoczny dla zalogowanych], the carburetor would determine the required quantity of fuel per cylinder/per engine cycle. In other words [link widoczny dla zalogowanych], the simple version of the ECU’S would control only the quantity of fuel injected into each cylinder [link widoczny dla zalogowanych], at each engine cycle. The advanced types of engine control unit (ECU), which are fitted on most modern cars, are capable of controlling the ignition timing, variable value timing (VVT) and other peripherals.The ECU’S (Engine control unit) monitors the engine by using sensors so that it can gather information about the cars quantity of fuel, ignition timing and other such parameters. The ECU works
