Nog 'n 4Y EFI install

[Chris16v]

Ek ry nou my Hilux so 7 maande nog met die Carb op en met al die gelees van die ouens wat hulle sin verander het na EFI het ek besluit om dieselfde te doen Wel nie presies dieselfde as die res nie ek van so bietjie kortpad ... maar eers meer oor dit sodra ek my geskenk pakkie vandie kaap gekry het meer , sit nou en wag vir die courier om hom aftelewer .

Kortpad?

Probably throttle body injection with the carb body, this can be done with a single "big" injector running in batch mode. The benefit are there, but limited, because one of the big advantages of std EFi, our way, is that the injectors sit very close to the head. The fuel travels a very short distance before being ignited in the cylinders.

And the disadvantage of the short travel would be what? As far as I understand it atomization will be improved as there is no time to form droplets.. or does it have to little time to mix with the air?

[krazy_kameleon]

other way around - the fuel comes out of the injector in a very fine mist.
every bend it encounters causes the fuel to fall out of suspension causing droplets. (think of mist hitting a window and forming droplets)
remember that liquid fuel does not burn, only fuel vapour burns.

This is why some manufactures are now building direct injection engines where the injector actually injects straight into the combustion chamber under huge pressure.

The short distance is a major benefit! With throttle body injection the fuel vapour still has a long way to travel through the intake mani, hence the loss of throttle response.

If it is this it is just a 1/4 of the full potential one can get. Rather spend the money on the parts and do it yourself and get the full benefits.

Direct injection with the 3Y-E manifold much better.

Maybe "Kortpad " was the wrong word to use , Gents I bought the 4y engine that Allan ( Hoppy ) had for sale , they Delivered it on Tuesday but still did not get a gap to open it but will do so today and add some pic's.

[LouisZ]

That is perfect!!!

[Chris16v]

Kan nie meer wag nie :)

[Willied]

Baie geluk!! Welkom by die EFI club!!

[Chris16v]

Dankie

[Mr_B]

I know that engine... very nice indeed!

[Chris16v]

Ok , Louis ( 4x4 Megaworld) het die die bakkie kom haal Saterdag oggend saam sy Nuwe / Ou engine , kort nog net so paar partjies dan het hy alles wat hy nodig het om klaar te maak . Sal fotos opsit soos ek dit kry , wil ook net vir Louis dankie se vir sy geduld met my en al my vrae en die rondry wat hy doen om my te help soek vir al die parte

Groete

Ok, daar is so paar weke verby vandat ek laas 'n update gesee het , hier is so paar fotos van voor en na die tyd.Die bakkie het gister gestart en Louis het hom gevat vir 'n test drive en in sy eie woorde " B!@(^#m dis lekker krag " so ek kan ook nou nie meer wag om te voel wat die EFI maak op die 4Y nie.Daar is nog net so paar klein goedjies dan is hy klaar

Dis hoe hy gelyk het voor die tyd

Christo

Het jy nou al die EFI getoets bestuur?

[Chris16v]

Dawie,

Jip Louis was gisteraand hier met hom , en al wat ek kan se is WOW wat 'n verskil nog net "Fine Tuning " . EK kan regtig nie glo dat daai trokkie nou soveel krag het nie 120km/h sommer gou gou

[The Legend]

Lekker man,geniet hom.Ek is nie n dag spyt dat Louis my bakkie ge-EFI het nie.

[Chris16v]

Ok , ry nou die bakkie so 3 dae en mens moet amper weer die trokkie leer bestuur , ek kan nie glo hoe groot verskil dit maak nie , ek sal enige ou aanbeveel om sy 4Y te EFI.

Groete

[hilex1uz]

Bly jou nuwe 4y is n sukses.sal graag wil weet wat is die verskil in petrolverbruik

[Chris16v]

hilex1uz,

EK kan nog nie se of daar 'n verskil is in die petrol verbruik nie , sal oor so maar km'ss kan se.

Groete

[Chris16v]

Net so vinnige update oor die EFi conversion , ek het nou so 2000km gedoen en alles loop reg altyd reg en gedink julle sou die Dyno uitslae wou sien , ongelukkig het ek nie 'n Dyno gedoen to die bakkie nog carb was nie .DIe gemiddelde pertol verbruik is so 7km/l werk toe en terug en hier in die dorp rond , nog nie langpad gery nie.
