THP Engine change

[Superfly Guy]

Looks like it's not a brand new engine, just a modified version of the existing THP - it's been on sale in China since March:

That might be the current engine with a slight tune, my 150 was 160 at stock.

Yeah my eHDi 110 was in fact 115 and then Citroen launched the 115 the following year

I may be wrong but with the DS5 LS being a heavier car, Citroen may just have tuned the engine a smidge to keep the performance figures more respectable.

Yeah, I cant see China worrying out Euro V rules

Looking forward to seeing the full spec in comparison with the THP155 biggie

[Chris]

Any update on this Biggy?

Bump...

Citroen has today release a PIB stated that the THP 155 engine will finished production in November this year until further notice.
The engine is to be replace with a new Euro 6 compliant THP 165 engine which is equipped with Stop & start technology.

Wonder if its GDI? As the THP 155 is in production until November, cant see the new engine being available until, maybe , February 2015?
Possibly beginning 2015.

I was in the dealership on thursday and they where expecting the new engines cars to be around 8 weeks. i will be speaking to them either today or tomorrow about it again

Yes it is GDI (gasoline direct injection) and has the engine reference code of; EP6 FDT.

That obviously maintains the spectre of the inlet valves issue then?

It does indeed, that said, whilst we continue to vent the crankcase gaseous mixture into the dry air intake stream, incorporating GDI technology, we will always have the inevitable problem of excessive carbon deposit on the inlet valves.

The 2nd generation THP engines with the dual vanos camshaft technology, courtesy of BMW, do offer marginally better protection from the issue from excessive carbon deposit build up on the inlet valves, this is down to the variable valve control (lift) of the inlet valves, 0.3 - 9.5mm of valve lift, this precise valve lift control, offers no vacuum at idle or light (cruising) throttle openings, this reduction in vacuum offers no available draw of the crankcase gas mixture through the internal rear individual inlet tract venting passages, allowing all the crankcase gaseous mixture to pass through all the troughs, traps and valleys incorporated into the camshaft cover, before taking the very long route, into the air intake stream pre turbo, so you can get an idea of the internal passages of the THP engine I am referring too, I've included a picture to help.

The later engines are lot more refined, well the 208GTi is anyway.

Only from what I've already explained, dual vanos camshaft control, the engine image I have included, is the later engine.
