Comments for Ford Releases Results Of Direct Injection at http://www.ecogeek.org , comment 1 to 16 out of 16 comments http://www.ecogeek.org Mon, 23 Nov 2009 03:58:43 +0100 FeedCreator 1.7.3 http://www.ecogeek.org/automobiles/2666#comment-26954 Turbo Direct Injection - mike Mon, 18 May 2009 11:44:49 +0100 http://www.ecogeek.org/automobiles/2666#comment-26395 I'm an ex out board tech.We are all getting dubpt.Mercury makes an outboard two stroke that uses the real concept of direct injection and could easly be adapted to a four stroke.The motor is called the optimax.It uses two injectors in line with each other.One injector for fuel ,the other for compressed air.This system on a 2.5L 250hp two stroke @7000rpm makes better power,fuel comsumption and emissions than the same four stroke fuel injected outboard @5000rpms.Look it up - dave Tue, 28 Apr 2009 13:43:03 +0100 http://www.ecogeek.org/automobiles/2666#comment-25891 Why would somebody need a 3.5 liter engine to go to his work or on vacation with his family? Modern 2.0 ~ 2.5 liter engines are MORE THAN ENOUGH for family trips and 1.4 liter for the daily commute. If you don't change the way you think not even the best hybrid technology in the world will be enough. Mercedes and Toyota are planning for a total shift to hybrid-engine car making while Ford is revamping old technologies... - hyperspaced Thu, 09 Apr 2009 13:26:28 +0100 http://www.ecogeek.org/automobiles/2666#comment-25792 All it will do is allow you to make bigger trucks and SUVs without worsening the fuel economy. Hurray. - jac Tue, 07 Apr 2009 12:35:33 +0100 http://www.ecogeek.org/automobiles/2666#comment-25773 This may be a small step, and may not be the most cutting edge addition we have seen in the auto industry, but it is a step. I applaud Ford for discontinuing the massive SUV line, and moving in the right direction. I think Ford will have the ability and flexibility to launch these new additions to their product line much more so than the other auto makers who have asked for a hand out from the government. - Brian Parker Mon, 06 Apr 2009 15:08:30 +0100 http://www.ecogeek.org/automobiles/2666#comment-25772 Reported earlier was this eco-boost technology (gasoline turbocharged direct injection) combined with a second injector for ethanol. The ethanol injector allows the compression to be doubled without knock, increasing torque, and supposedly allowing 20-30% fuel economy increase over a conventional engine. The plain eco-boost news here is the same as that reported January 2008 - Carl Mon, 06 Apr 2009 14:19:47 +0100 http://www.ecogeek.org/automobiles/2666#comment-25771 Direct injection technology has been around for a while with diesel cars - that's the TDI nomenclature from VW - and this is similar. This is for gasoline engines. Direct injection allows for much more precise timing, and the higher pressures necessary to deliver fuel into a compressed chamber improve the spray pattern - and combustion - drastically. Ford's a little late to the game, as Mitsubishi has been using DI on gas engines for years. Other manufacturers in Europe and Japan have been using the technology, too - what makes this noteworthy is that it's happening with one of the Big Three. Finally. - Matt James Mon, 06 Apr 2009 13:27:27 +0100 http://www.ecogeek.org/automobiles/2666#comment-25767 Maybe this is an advanced TBI engine (throttle body injection)--which was very early fuel injection. Any more detail on how this works? Maybe we can mod existing TBIs to this line of injection/combustion. Keep in mind these results are probably measured from the flywheel and therefore about 10-20% overambitious. - david ben avram Mon, 06 Apr 2009 11:41:38 +0100 http://www.ecogeek.org/automobiles/2666#comment-25766 All this talk about "new inovations" by the US auto makers is BS!!!! They selll cars in Europe that already get way better fuel ecconomy. It's all greenwashing. Putting ECO in front of something doesn't make it so. The US automakers really need to get serious about giving us better cars. Talk is cheap. - JonnyUtaw Mon, 06 Apr 2009 11:19:26 +0100 http://www.ecogeek.org/automobiles/2666#comment-25765 Really? A V4? not an inline 4cyl? - Eric Mon, 06 Apr 2009 10:32:13 +0100 http://www.ecogeek.org/automobiles/2666#comment-25759 Can you pull a horse trailer with your Toyota Pius? Didn't think so... I agree that it may be too little, too late, but at least they are doing some R&D... - MD Mon, 06 Apr 2009 10:06:55 +0100 http://www.ecogeek.org/automobiles/2666#comment-25757 This may work better in a hybrid engine. It could boost mpg above 50 and I would say this is an improvement. 22 to 25 mpg is really nothing to write home about. I can do that by just controlling my acceleration. - moe Mon, 06 Apr 2009 09:48:54 +0100 http://www.ecogeek.org/automobiles/2666#comment-25756 TDI stands for Turbo Diesel Injection. Does this look like a Diesel engine to you Russ. - Ben Mon, 06 Apr 2009 09:39:15 +0100 http://www.ecogeek.org/automobiles/2666#comment-25754 The Cadillac can only muster 22 MPG while emitting 248 g of CO2/km. The Lincoln gets 25 MPG while emitting 218 g of CO2/km. That is a 12% increase in efficiency. Where I come from that is significant. - Tom Mon, 06 Apr 2009 09:20:55 +0100 http://www.ecogeek.org/automobiles/2666#comment-25752 [i]The Cadillac can only muster 22 MPG while emitting 248 g of CO2/km. The Lincoln gets 25 MPG while emitting 218 g of CO2/km.[/i] This doesn't seem like the kind of fuel savings that's worth mentioning other than having "Eco" in the name, which is really just greenwashing a still inefficient system. Let's see at least 50 mpg before calling "Eco". Please. - adam Mon, 06 Apr 2009 08:16:23 +0100 http://www.ecogeek.org/automobiles/2666#comment-25745 This is the TDI that has been in use in Europe for years? Detroit is really on the ball! - russ Mon, 06 Apr 2009 05:45:39 +0100
