Thread: The Igenium engine. Will it last?

thats a lot of boost.
my 2l SR20 in my silvia ran 18psi

Will they last?,..I have wondered the same thing myself, with respect to today's trend to smaller, higher output engines.
Pretty much the same trend in petrol & diesel engines, the diesel may be higher on torque, but petrol versions are achieving astronomical power outputs......400HP+ from 2L is not unheard of these days.
So, yes, I reckon they will last, BUT, if ya're out of warranty & ya have a problem, ya might need a friendly bank manager. IMHO, servicing these high tech electronic beasties could also be quite "complex".
Pickles.

I think that the engines have been designed from the ground up to handle that sort of boost. most engines around these days are not designed like that and wont handle it. It will be an interesting experiment.

Probably helps that I have been around for a while. I remember exactly the same sort of sentiments being aired about the TD5. And about the 2.25 diesel that revved higher than any self-respecting diesel. And I am sure the same or similar sentiments were around when Henry Ford came up with an engine that actually ran at 1500rpm in 1908!

53psi is a lot of boost pressure. But you'd imagine that if the motor was designed for that from the start then it should...

Its definitely a bit of pressure to put through the intercooler hoses....

oh how things changes how things all stay the same lol
with out seeing anything other then the boost numbers at a guess they are using a variable valve timing system to achieve a miller cycle type effect.
they do this on diesel's to reduce Nox emissions and it also acts as a slight air pump.
basically they are using the massive boost to pump out the cylinder at the end of each cycle by holding the exhaust valve open and opening the intake and using the boost pressure to effectively blow the last crud out (and prob some fresh air as well) so every power cycle is fresh.
then they are prob also using the Atkinson cycle as well and holding the intake open to a certain point so the actually compression of the cylinder is lower so that when the power stroke finishes the cylinder pressure is same as atmosphere pressure meaning you got everything out of it, it will also be cooler which will also help with nox emissions

the last manufacture i know of doing this was Cat truck engine with their acert c13 and c15 engine's they did all that with something similar to a Jake brake setup so they could avoid erg and adblu then for euro5 had to go egr but no adblu

so id say land rover is doing this to avoid having to use adblu which then means paying john deere for use of their patient and also their customers dont have to have their vehicle filled with adblu ether

I think the better question would be: ' Are they expected to last?'. With emission legislation in Europe and California being what it is, I imagine they are thinking in cycles of no more than seven years. Times have changed, folks. Not for the better, IMO.
