How does the ECU work on a diesel engine?
The driver requests the torque or engine speed requirements via accelerator pedal potentiometer thereby sending a signal to the engine ECU which then, depending on its mapping and data collected from various sensors, calculates in real time the quantity of injected fuel required, thus altering the fuel rack to the required position.
What does an EDC distributor injection pump do?
EDC distributor injection pump Electronic Diesel Control is a diesel engine fuel injection control system for the precise metering and delivery of fuel into the combustion chamber of modern diesel engines used in trucks and cars.
How does an injection pump in a diesel engine work?
Diesel engines work by compressing only the air to increase the temperature to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously. This contrasts with spark-ignition engines such as a petrol engine which uses a spark plug to ignite an air-fuel mixture.
Is the ECU the same as the transmission?
In the Automotive industry, the term ECU often refers to an Engine Control Unit (ECU), or an Engine Control Module (ECM). If this unit controls both an engine and a transmission, it is often described as a Powertrain Control Module (PCM).

What is the job of an ECU in an engine?
The ECU has the job of controlling the fuel injection, ignition and ancillaries of the engine using digitally stored equations and numeric tables, rather than by analogue means. An ECU has to deal with many variables when deciding the correct mixture ratio.
What should I do if my fuel injection pump is stuck?
If it is stuck then don’t tap or hit it as it will damage it. You would need to take it to a diesel engineers to have the seized element replaced if you have no luck. With the TEF fuel injection pump you can also remove the cover plate to look inside at the components. Share This Story, Choose Your Platform! Comments are closed.
What does the ECU do at full throttle?
It doesn’t stop there. For best power levels and safe combustion, the ECU must change the ratio of the mixture and inject more fuel under full throttle than it would during cruising – this is called a ‘rich mixture’.
