The Jaguar AED, in full the Automatic Enrichment Device, is an ingenious choke mechanism on Jaguar's SU carburettors. It effectively works as a mini carburettor that automatically enriches the fuel when needed. We specialise in overhauling these units. A job that demands extreme precision.
Our specialism: overhauling the Jaguar AED
As lovers of classic cars, we are often fascinated by the ingenious technical details that make these vehicles unique. One example of such a technical gem is the Automatic Enrichment Device (AED) found in various Jaguars.
The AED mechanism is a clever addition to Jaguar's SU carburettors (Skinners Union), designed to optimise the fuel and air mixture for different driving conditions. It is a choke mechanism that works exactly like a mini carburettor. It contributes to smoother engine running and improves performance. The system adjusts the mixture by adding extra fuel enrichment when needed, such as during cold starts or acceleration. That gives better response and more economical running.
What makes the system even cleverer: it takes the surroundings into account and follows the engine closely. That is how a Jaguar XJ drives with even more refinement.
We know these technical gems inside out and understand how important they are to a classic car. Do you drive a Jaguar and would you like the AED system inspected or overhauled? Then we will gladly help you preserve its original operation.
Precision work: 7 cm and 45 individual parts
The AED is a crucial part of the Jaguar carburettor system. Our overhauls include very accurate setting up and the restoration of all AED components. Setting up and repairing these complex systems correctly demands extreme precision and knowledge. The AED is 7 cm long and contains 45 individual small parts. Even small mistakes can lead to significant performance problems.
This is where Carbservice.nl makes the difference: with our experience and expertise we have overhauled countless AEDs, so we know exactly how to treat these systems for the best performance and reliability.
Original, or conversion to a manual choke
We value authenticity highly, which is why we use genuine parts to make sure the system works perfectly to factory specifications. We also offer the option of converting the AED system to a manual choke (at extra cost), so you can choose the type of operation that best suits your driving experience. That way we keep your classic Jaguar XJ in top condition, while taking your preferences and wishes into account.
