Can anyone give me a description of how the Etec fuel & oiling system works?

I don't get what you want to know Fed

The E-TEC is just like a normal 2 stroke, you put straight Fuel in the tank

& 2 stroke oil in the oil tank in the outboard

And they get mixed together during the outboard running or something i don't know outboards

Was talking with the master about this last week Dan and he made a call to his outboard guy but the info was just a little vague so I thought I'd put the Q here for a bit of discussion.
It seems that the fuel & oil don't get mixed in an Etec like a conventional 2 stroke.

My Qs revolve around where exactly does the fuel inject, ie: intake manifolds or directly into the heads?
Where exactly does the oil get injected (all points) and how does the oil eventually get to the combustion chamber to be finally burnt.

This post is partially to give Jumpy a reminder to collar his OB guy and I thought people might be interested.
Once we figure out Etecs then we try & figure out Optis, I think they're injected too but more like a conv 2 stroke.

DO YOU GET IT NOW?

Twit Top !

You just dont get it do you ?????????

Fed why ewe no rissen, told ewe how system works

I'm off have to go finish wiring up my new auto pilot so i can drive boat hands free , dont want to get booked behind the wheel

All you did was repeat what your Ob guy told you and it was a bit vague mate.

Auto pilot = Full time use of safety lanyard, wearing a life jacket at all times & Jim the lifesaver.

Thet lanyard to kill the motor sounds like a good idea
i can just hear jumpy screaming (after falling off the boat)
stop and turn around u stupid thing?

Ewe Tu R a pair of Wally's

What part didn't ewe get Fed ???

I'll type it slow so ewe can understand this time

There's no mixing fuel/oil on the etec's, there's a series of tiny injecting oil points along the crankshaft housing, oil gets injected onto crankshaft lubing it along with the other working parts bearings etc.

Fuel on it's own gets injected into the cylinders

Bet you're wodering how cylinders get lubed & what happens to oil in crank ???

Crank pressure suck oil into cylinders when pistons move in & out.

Oil injected 2 stokes mix oil/fuel in fuel evaporator & it goes into cylinders allready pre mixed

OK, so whereabouts on the engine are the fuel injectors and whereabouts are the oil injectors?
Did he mention any scavenging of excess oil from the crankcase?

He's a worry Pez, did you know his mate Jim saved his life when he fell overboard?
The auto pilot would just keep going without even a chance of the boat coming around in a big arc.

Geez you're a GOOSE Fed
Woops we all new that allready

There's a little thing called wrist remote control

You really need to get out of the dark ages

So you can steer the boat back to you? Excellent!

You could launch the boat while you were at the trailer then steer it over to the wharf.
That would leave the natives gob smacked. HaHaHa!

I don't bloody get it

Geez Fed dont you know anything why ewe no risten:lol:

Tried to google up a pic of a etec powerhead to educate you but all the pics were crapy
Lay off the Goose Pills & stop giving them to DanuSun

Wouldn't it be easier to just say you don't know?

YES I have heard about wrist controls
but have also heard they arnt realy water proof yet
you will have to wrap your arm in glad wrap Jumpy

Might be easier but would not give ewe the satisfaction & i would be telling a big porky.

Dont call you goose for no reason

So tell me Mr Goose how on earth do ewe expect to see wittle brass barbs embeded into the crank cover through all the electricals, hoses etc surrounding the barbs [they're the wittle things oil hoses attach to Your Gooseness]

You go look for a pic of an ETEC crank cover & i'll show you exactly where they are
Woops wont have to cause even a goose will see them

Talking to you is like pulling teeth from a googlefish.

Right, the oil injectors are on the crankcase cover, was that so hard? next....

Geez Fed use your noggin where the hell any injector goes on motor ???

They're feeding something

Here's a clue tis not the battery

1) Intake manifold.
2) Crankcase.
3) Cylinder head.

Choose your poison, if you don't know just say so it's no big deal.
You always seem to want to make a pissing comp of these things, I just don't get it.

Then why are you asking me for ?

Not a fan of those etec's & have only ever given them a passing eye they're not my idea of a motor

When we last spoke you were going to corner your OB guy to clarify it for us and I thought you may have found out.

I think Nimrod had an Etec so maybe he knows.... NIMROD!

I saw one at the ramp a couple of months ago, jeez it was quiet.

Still wondering how the Optis do it too.

Well i've had better things to do since then than running around looking @ etec's

Like doing alot of sleepies & trying to shake this F()*&^^$$# Flu

Yeah I was hoping to go for a fish tomorrow but HMMM?

Maybe it will improve during the day.

Got your auto pilot finished yet?

No fishing tomorrow Jumpy.

Yeah i'll be out but rugged up

Bloody chris booked the boat a week ago to fish a comp this weeked even made an effort to go get a tag pole

why the question Fed
I just don't get it

Paul

Because he's a Goose

The question was a follow up on a conversation we had a couple of weeks ago Poly, believe it or not Jumpy was pretty interested in finding out exactly how they worked too.

Fuel gets injected through the heads

Thanks mate.

get a kayak and you wont have to worry about etec motors, dirty smelly things they are blar blar blar blar

Paul

Buy a Yammy four stroke and you'll have no smelly fumes, your ear won't go deaf, hell, the only problem you'll have is keeping the fuel tank topped up with fresh fuel !

I've used mine for 4 trips and i've only dropped 2 bars on the fuel meter

is that 4 times across the river and back quentrex101
