procyon Posted September 15, 2009 Share Posted September 15, 2009 Can someone clarify for me if the 1.6L Ecoboost is a member of the New I4 family. Sure looks like it from the pictures but it has a timing belt rather than chain and it is being built at Bridgend which built Zetec. Quote Link to comment Share on other sites More sharing options...
AM2 Posted September 15, 2009 Share Posted September 15, 2009 (edited) Can someone clarify for me if the 1.6L Ecoboost is a member of the New I4 family. Sure looks like it from the pictures but it has a timing belt rather than chain and it is being built at Bridgend which built Zetec. I do remember reading an article before that the 1.6 EcoBoost is supposed to be based on the current 1.6 Duratec (which is based on the old Zetec-SE), I was just expecting them to give it a timing chain since all the larger displacement (newer generation) Duratecs (1.8 and up) use timing chains.

twintornados Posted September 15, 2009 Share Posted September 15, 2009 (edited) oooh...I got an idea! Lets get this in the Crown Victoria (and a 12 speed automatic while we're at it) so it can be built forever....

one2gamble Posted September 15, 2009 Share Posted September 15, 2009 I have ZERO objection to a belt if the engine can mimic the smoothness of the imports that also shun chains....just means a 60k replacement, BUT the press always comments about perceived JAPANESE smooth spinners...belts are a large part if that...... sure, as long as they can figure out a way to not make it cost an arm and a leg to replace the belt, theres also no way its due at only 60k.

Deanh Posted September 15, 2009 Share Posted September 15, 2009 sure, as long as they can figure out a way to not make it cost an arm and a leg to replace the belt, theres also no way its due at only 60k. Japanese have been doing it for years and you NEVER seem to hear anyone bitching about it or replacement cost...my ex's Acuras was due at 60k...she went too long, no internal damage thank goodness....

Newer Hondas and Toyotas have 90K belt replacement intervals. My Acura has a timing Chain that does not need to be replaced during normal service intervals. Its only recommended that it is checked out at 120K. I would imagine the 1.6L EcoBoost would have a similar 100K belt replacement schedule.

battyr Posted September 16, 2009 Share Posted September 16, 2009 I think the hybrid 2.5 is the same as the regular 2.5 but with a different intake camshaft. I think they did other things to cut cost, but you are essentially right. Quote Link to comment Share on other sites More sharing options...
battyr Posted September 16, 2009 Share Posted September 16, 2009 Different pistons as well to increase compression ratio to 12.3:1 versus 9.7:1 for the non-hybrid. Of coarse. Quote Link to comment Share on other sites More sharing options...
battyr Posted September 16, 2009 Share Posted September 16, 2009 Is there any possibility to have hybrid system with EB engine? Any advantage or disadvantage Why not a EB Atkinson cycle engine? The turbo solves the power problem with Atkinson cycle engines. Quote Link to comment Share on other sites More sharing options...
old_fairmont_wagon Posted September 16, 2009 Share Posted September 16, 2009 The atkinson cycle, by definition, doesn't work (that well) with forced induction. What you're maybe thinking of is the Miller cycle (Mazda millenia 2.3S was the last car to use it). Hit up wikipedia for a nice writeup on it.
