Hello, I just bought Escort form 91 with 1,9 l engine and manual tranny.. I do not know what is it power. On Engine it is written: 1.9 SEFi. Can you tell me what is the difference beetwen EFi and SEFi?
How many of us are from Poland?

Welcome to FEOA man.

The Escort you bought is the first year for the 2nd generation Escort LX (built between 1991-1996). As you said it has a 1.9 SEFI engine. SEFI=sequential electronic fuel injection. EFI=electronic fuel injection.

The 1.9 produces 88 hp and 107 lb ft torque.

I'm from the US btw :wink:

with SEFI- sequential blah blah blah, the injectors fire separately and right before the downstroke of each cylinder, so you tend to get more power and efficiency blah blah blah.

with EFI, it fires all at once, waits for all 4 cylinders to do their blow-uppy thing, then fires all at once again... it's not independent like with SEFI.

I'm not sure if it fires right above the intake valves lke with SEFI or up higher though...

I did not know all that. *soaks up siragans knowledge*

So whats the advantage of having EFI over SEFI in a car like a GT then? :?

SEFI has an injector for each cylinder in the head right above the intake port and fires just before and during the intake stroke for that cyl.

EFI usually has one injector for every four cylinders mounted before the intake manifold, usually in place of a carburator feeding the entire engine.

EFI was used in the early application of fuel injection on gasoline automobiles. Somewhere along the line someone thought that an injector for each cylinder would be a good idea and might produce more power. It was a good thought :)

You're thinking of CFI or Throttle Body Injection (TBI).
In a CFI setup, the single injector is mounted directly above the throttle body and as air gets sucked down through the throttle body, it mixes with the gasoline mist from the injector.

I'll try to straighten things out a little bit here...
SEFI (sequential electronic fuel injection) is a variation of EFI.

SEFI is a specific type of multi-port injection that delivers fuel in more precisely timed pulses corresponding to the opening of each intake valve, It takes advantage of the atomized fuel spray from the injectors to achieve a more precise combustion for better performance, often with improved fuel economy.

MEFI (Multiport electronic fuel injection), also known as direct port injection uses individual port-mounted injectors to deliver fuel directly to the intake inlet for each cylinder. This more even distribution of fuel improves power balance between the cylinders, maximizes combustion efficiency and improves driveability and performance. The system squirts fuel into each cylinder with every revolution of the crankshaft.

Hope this makes sense.

I'll add to the confusion :twisted:

This system is not employed on any scorts (to my knowledge), but some of you might find it interesting.

CIS - Continuous Injection System.. a system where the air flow is metered mechanically (usually through a flapper door -5b-) and regulates fuel flow in direct proportion to the movement of the meter. The injectors -7- are little more than reeded pressure valves that don't open to let fuel out until fuel pressure is sufficient. The fuel constantly dribbles out or sprays out into multiple ports regardless of the crank position. This system was employed by many european cars in the 70's and early 80's, with Bosch K-Jet being one of the most popular types of CIS injection. It's incredibly reliable and rarely goes out of tune once set, but, because of the intake obstruction of the mechanical meter, limits throttle reponse and power. These systems can be found with and without lambda control (O2 sensors).



When you look under the hood of an older VW rabbit, or Volvo, or Benz, or BMW and see braided steel or clear poly injector lines. coming from a distribution block next to an air meter, you'll know what you're looking at.

Pics? I'm guessing that you have a European Escort, which most of us Americans are totally unfamiliar with.

are you dumb? he said he's from poland so what makes you think he would have a european escort? Commen sense would tell you he has a Poland Escort :lol:

I'm reasonably sure that they don't make Escorts in Poland. I think maybe the only place in Europe that makes them is in England, but I'm not 100% sure. And I think the engine size is different. So pics would clear things up.

Well if it's english then it'd be the escort RS, (non cosworth)... which had like 140 turbo? I think... But it's 90's so it's probably around 130 (non turbo), just like a gt, even if it's english. Not sure, but I was reading about them... and they look really nice and sleek! I want one!

Okay so I'm dumb. Escort RS was turboed, made in 1984-1986, and had 132 bhp (1.6 l displacement). Was replaced with the newer style escort which is... Grr... Ford RS Turbo Series II, which was also turboed and produced until 1991. It produced the same hp and torque as the previous one at 250 lower rpm, respectively (also with 1.6l displacement) ... But judging by the sound of things I don't think your escort is turboed, (is it?) so it's probably an american one, I'd be willing to bet...

It sounds like an American Escort, but some pictures would definately help...

Yep, sure sounds like it, and if it's american, and 1.9... Then it's probably an LX, correct? Which would mean 88 horsepower. BTW, these things are awesome!!
