The engine control module supervises the proper operation of our vehicle, monitors most of the sensors in the engine compartment to manage the vehicle’s fuel-air mixture and regulate exhaust emission control systems.
It regulates four main vehicle systems, controls the mixture, i.e. the ratio of fuel to the supplied air, the mixture should be constantly monitored and adjusted, for example when we press the gas pedal, a larger amount of the mixture must be delivered to the engine compartment, and thus also a larger amount of air through the throttle. The engine controller also controls the idle speed in such a way that the car does not go out. It controls the variable valve timing and also controls the ignition of our car. Regarding the air-fuel ratio, the computer uses sensors to regulate the ratio of oxygen to fuel detected in the car’s exhaust to detect the optimal mix determination. Some of these sensors include air flow sensors, oxygen sensors, and fuel sensors. At idle speed, the engine control module relies on sensors located at the crankshaft and camshaft that track vehicle speed and engine load by monitoring the engine speed. The variable valve timing system controls when the valves are opened in the engine to increase the power or quantity of the mixture.
The engine computer also controls the ignition time, but also controls many other systems. The beginnings of more advanced control of some engine components date back to the 1970s. At that time, the first carburetor control systems with electromagnets were introduced, the cars also began to control the mixture at idle. In the 80s, when the fuel injection was introduced, the engine computer also took over the role of controlling injection and ignition.
In the 90s, engine control systems also began to monitor the operation of diesel engines, with turbocharging systems. Over time, the controller also began to control the turbocharger and exhaust gas control system, when more stringent regulations regarding the content of exhaust gas began to appear. The engine controller itself may also break down over time, in which case it will be necessary to visit a specialist or replace it. Repair of the controller requires disassembly of the device and performance of quite detailed, precise electronic works or re-programming of the device. This is similar to repairing the motherboard in the computer, some experts recommend removing and opening the device and looking for signs of electrical damage, signs of burn, breakage of soldered components and paths, or other similar abnormalities. It can also be corrosion caused by damage caused by acid or moisture, it will probably be clearly visible. Cabling damage can also occur, so check all connections first. Failure can also be caused by broken sensors, there are many things that need to be checked when we think that our driver is damaged. If we know for sure that it is damaged, you may need to replace it, then you can buy a replacement using the page: https: / /www.worldecu.com/en/ecu-engine-control-unit .
