Can a Jaguar supercharger be rebuilt by Eaton?
The sub-flush needle bearings replacement is included in the Jaguar Eaton Complete Supercharger Rebuild Service. These two superchargers are not interchangable because the protruding bearings will prevent proper installation of the Jaguar inlet plenum. systems that use water / methanol injection.
What are the different types of EGR valves?
This helps to ensure the car maintains fuel efficiency and emits fewer emissions. There are two types of EGR valves; a vacuum-operated and an electronically controlled EGR valve. A vacuum-operated EGR valve is usually only found in older vehicles. It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open.
What happens when an EGR valve is not working?
When your EGR valve isn’t working correctly more emissions will be emitted. As aforementioned if the valve is stuck open the temperature is lowered which prevents all the fuel from burning. This means an increased flow of unburned hydrocarbon gases coming out of the tailpipe.
How does EGR reduce the production of NOx?
To reduce the amount of NOx pollutant emitted from your vehicle, exhaust gases need to be cooled before being emitted from your vehicle. In order to achieve this, they are introduced back into the combustion chamber via the exhaust gas recirculation (EGR) valve; this reduces the temperature and thereby inhibits the production of NOx emissions.
Why is my EGR valve sticking on my Jaguar?
Most common…sticking EGR valve/turbo actuator valve/Deisel particulate filter…..but then it might turn out to be something a little bit more mundane..re Espresso’s post The most likely cause is a sticking turbo actuator. Other causes are; Inlet air leak or leaking hose.
When does Jaguar XFS go into restricted performance?
Driving home last night and decided to enjoy the benefits of my XFS………………..after about 35 miles it decided to go into ‘RESTRICTED PERFORMANCE’ mode. Still would run at 70 – 80 mph but just very little acceleration. Pulled over and tried turning off and back on but no luck and the same when I got home 5 miles further on.
Is there a air leak in a Jaguar?
Technician from Jaguar Assistance has been out and believes there’s a small air leak. Both turbos are hitting 100% boost but when the second turbo hits max boost there is a discrepancy between the mass of air going in and coming out!
Why does my Jaguar go into restricted performance?
It went into Restricted Performance almost every time I went out in it over a period of several weeks, the French dealer it was recovered to diagnosed a faulty turbo actuator but couldn’t do anything before I was due to leave for the UK.
