The cars of today are not just about the engine, it is about the entire engine management system. It is responsible for the entire combustion process – this means that it mixes the right amount of fuel to the air entering the engine and igniting the compressed air/fuel mixture in the cylinder.
The engine management system is where typically where the most advanced vehicle technologies are found. It can include 30 plus components and 50 computer modules to deliver the millions of lines of code that keeps the vehicle running efficiently.
So it’s important that engine management is part of your car’s maintenance.
The engine control unit.
Controlling the engine is the most processor-intensive job on any car and that’s all down to the Engine Control Unit. It uses data from the multitude of sensors located on the engine itself.
It can include everything from the speed and temperature of the intake air to the amount of oxygen in the exhaust.
It then processes this data and performs millions of calculations every second… this determines how each sensor should respond in order to achieve the very best engine performance, emissions and fuel economy.
