Ingenium engines and what are the differences

Post by eski » Sat Apr 03, 2021 4:24 pm

I have been researching for fun and to add knowledge about Jaguar Ingenium engines and what are main differences with those as information is not so available and lot of misinformation is there (in my opinion).

Two main categories, petrol and diesel. As this is uk XE forum lets keep for now range in four pot design (I think in China 1.5L three pot petrol is available). Differences are based on jaguar part numbers and other various jaguar information pamphlets.

Diesels:
All two liters.
Three variants, mid output 163hp and 180hp. High output 240hp
163hp, 180hp and 240hp version all have different injectors
163hp and 180hp same fuel rail. 240hp different.
163hp and 180hp same fuel pump. 240hp different.
163hp and 180hp have same turbo, 240hp version twin turbo.
163hp and 180hp engine block is same, 240hp different
Intercooler same to all. This is not complete list as I do not have details how all parts are different. I think this should be keep in mind eg adding tune to ECU.

Petrols
All two liters.
Three variants 200hp, 250hp and 300hp.
Basically 200hp and 250hp are totally same. I haven't found any differences in parts. 300hp version has different turbo, injectors and lower engine compression ratio (different crank, pistons, rods). Even exhaust is different. Not much.
All ingerium petrol engines have CVVL and VCT (continuous variable valve lift and variable cam timing). I have seen posts that 300hp version is some how different in valve/cylinder head but there are not different parts in parts catalog for different petrol versions.

Be cautious as few tuning companies say that all four pot ingenium petrol engines are same. Pushing 200hp/250hp to same limits as 300hp version (with I think smaller turbo and less flow rated injectors).

I can remember Jaguar Ingenium pamphlet where internal components of the engines (compression ratios etc) were posted.

Transmission and differentials
All manual versions have different differentials.
All automatic petrols have same differential
All automation diesels have same differential
note, I really like to know what is the real difference than part number.

Transmission for four pot petrols and diesels (I think) are same ZF 8HP45 but different casing for all applications (diesels vs petrols, awd vs rwd). In ZF page ratings for torque is 500nm for diesels and 450NM for petrols.

And as a disclaimer this is not a complete list. Please add and/or correct. My interest is as now my MY18 has run out of warranty. No problems so far, but for now I think I am going to keep it for a few years and it is always good to know what you have.

I always understood there was a difference in the turbos between all three, 200 has standard turbo, 250 has twin scroll and 300 has twin scroll with ceramic bearings, don't mind being shown I was wrong though :)

Eski,
the Ingenium engines are very complex. It maybe best to read the workshop manual.

How about topix subscription and read from the devil itself :) And that link is only for up to 2017 when petrol ingenium does not exist.

I understand where this comes from and also I was originally in same impression. In marketing papers (at least in MY18 model) is said that in only for 25t "This engine’s twin scroll turbocharger is fed by an integrated exhaust manifold that synchronises exhaust pulses.." one can get that impression, but reality is different. Why would anyone buy 25t model if it known that simple tune up could change you car to 25t.

Very good summary and accurate as far as I can tell.

You're right about the P300 - the multi air technology isn't just on this variant but it's applied across the P200, P250 and P300 itself. There was also misinformation that the P300 had 2 turbos.

Now with MHEV the diesel is now rated 200D both 163 180 have gone, the petrol is only available as a P250RWD & P300AWD, the 200 has gone.

That could confuse some people.
The P300e is a plug in hybrid with the 3 pot petrol engine (200PS) and electric motor - up to another 108PS hence the "300" branding.
It also isn't available on the XE at this time.
The P300 is still a 2 litre turbo four petrol with 300PS.
