Do I Have A Petrol System That Utilizes Electronic Sequential Injection ?

[samuri]

Does a 1996 skyline gts 4 door sedan ( non turbo) use a petrol system that utilizes electronic sequential injection ?

I beliebe this is a requirement if I want to run liquid injection LPG.

Any comments on LPG appreciated, except from the flat earth society.

Ahh... Yeah man... Rb engines (for the most part) are all injected...

There's only one version that's carburetted, an rb24s, in some random jap small car.

Any engine that doesn't have a carburetor, uses fuel injectors and an ECU, to inject fuel. Pretty much every petrol engine from the mid80s, is injected.

LPG isn't really the best option tho IMO, you hardly save much money anyway... Limits the amount of power you make, saps some power from you, adds weight to your car, and they use more fuel anyway, so you spend more at the bowser...

i can just imagine the boot space in a r33 with LPG

but why would u want to run LPG in a "performance" car

Over here in vic we have a vl turbo that runs 10s on lpg...... its still a bbq tho haha

there are different sorts of injection though. there is single point injection (basically a fancy carby) and multipoint injection. but yes, skylines as with most cars made after about 1990 use multipoint (sequential) injection.

The evolution seems to have been;

- carburettor

- single point/throttle body injection

- mutli point batch injection

- multi point sequential injection

- direct multi point sequential injection

There was also an RB30S im pretty sure, in old patrols?

since when is an n/a a performance car?

Just a nit pick, but multipoint, batch and sequential injection are all different,

Multipoint fires all the injectors at once, but at multiple points in the engine (hence multipoint)

Batch fires in the same way wasted spark ignition does, ie 2 cylinders at a time

and sequential fires individually in accordance to the firing order of the engine

just to nit pick what you are saying, both batch and sequiential are both actually multipoint injection. multipoint just simply refers to whether there is a single injection point (like at the throttle body) or multiple injection points (an injector in each intake runner). nissan specs attribute the 370z with having sequential multi-point injection.

Yeah but that is just marketing spin

A bit like holdens SI-Di shit...Spark Ignition Direct Injection...Spark ignition WOW REALLY! What were you using before that Holden?

[Trozzle]

Andrew, sort of on topic, but I agree completely with that point! Almost everything that companies advertise on their cars is just a name they give to a STANDARD FEATURE OF ALL MODERN CARS just to make it seem unique and special. SIDI is a prime example.

my point was though that both sequiential and batch injection are multipoint injection as they inject fuel at mulitple points. the batch injection just refers to multiple injectors firing it at once. it can be two or all of them.

Yeah I know what you are saying and I agree...Im just being difficult lol

[mad082]

damn, a bit hard to start an argument off that.
