The engine of the modern car has evolved significantly over the years from the internal combustion machine that was developed by Henry Ford. Today’s engines are far more complex, and a car’s Engine Control Unit (ECU) plays an important role in vehicle performance and tuning for the fuel injection system.
The Basics of the ECU
The ECU is very sophisticated and uses microprocessors and sensor data to perform processes. Its firmware can be reprogrammed using computer code or by replacing a small microchip which governs the activity of the car through precise computer calculations.
The amount of fuel that is put into the system determines its acceleration, and the ECU decides how much fuel will be released into the combustion chamber in a fuel injection system. Increasing airflow from the throttle causes the ECU to inject more gasoline. In cold weather, when the engine does not get warm enough, the ECU will compensate by supplying the engine with more fuel to allow the heat to increase.
The ECU uses mass airflow sensors to obtain necessary information to allow it to deliver the right amount of fuel to the engine. There are also other sensors that use data supplied by the ECU including the coolant temperature sensor, throttle position sensor and voltage sensor, which help the ECU adjust various functions, such as the operating temperature and system voltage.
The Advantages Of The ECU
The ECU is part of a highly developed engine management system that allows for better fuel economy and more responsive car performance. It is also environmentally- friendly, as it creates a lower amount of emissions from the vehicle. The ECU has the ability to control the major working parts of an engine and deliver a high level of performance that makes driving a true pleasure.
