injector pump

Is this a good way to set the pump timing? ( see the youtube video) It looks very good to me.
how far advanced do you recommend for running a Lister cs 8/1 on straight veg oil?

On a vehicle engine the stated advancement for veg oil is 5o more than standard.
No idea what that equates to in mm on a fly wheel.

Other method seems to be advance it to it nails, back it off a couple of degrees and all good.
I have set a couple of china and other small diesel up by just listening for a healthy diesel Knock and lock it in there

has anyone tried this method of timing?
is this the same as the spill method and is the first spot of fuel on the flywheel meant to line up with the zigzag injector mark on the flywheel. for veg oil another 5*
What do any of you think?

That method of timing looks about right.
Give it a try.
You will have to find a way to mark your flywheel at approx 20 deg BTC and then adjust your initial spray point to either side of that mark depending on the engine specs and the fuel being used.

I have only ever done China Diesels which I advanced as far as they would allow and still wanted more running them on Veg But On all the petrol engines I worked on, I don't think I ever set the timing to spec.

Many of the engines I played with were worked or modified in some way and even stockers would happily take a bit of advancement.
With the others, pretty much played with them till I found the sweet spot and that was never where the factory said they were supposed to be.

One thing with running veg oil.... If you intend to thin it with Petrol in winter, Be careful. IMHO, 10% petrol advances the timing in a diesel running veg oil about 5%. If the timing on the engine is already advanced and you are using a fuel that will light off earlier, Might be too much.
OTOH, if the timing on the engine is set 5o forward to start with, you may not need the ULP blend for starting anyway.

If you want to keep the oil thin with regards to the cold, Go to Kerosene, Turps or a non aromatic fuel.  They will thin the fuel without advancing the timing  at where the fuel lights off.

having the engine advanced for veg will always give the benefits of cleaner running, best power, easiest starting and good economy.... if you are worried about such trivial things.   ;D

I am running on wvo only The engine and 1200 litres oil are in the same building its well insulated so the temperature is around 35*c summer and winter I do not thin the oil other than the temperature of the building the engine runs for 14 hours a day with 1 hour gaps as all the heat goes into storage heaters.

I am just looking to get the original 1959 Lister CS 8/1 to run to its most efficient?

Edit: Oops, replied to the wrong thread  :-\  I moved it here ... "Water Steam Injection"
https://listerengine.com/smf/index.php?topic=8949.new#new


It's unlikely that you will need water injection on a continuous basis so consider an algorithm to intermittently dose the engine.
You may already be aware, but the arduino "uno" and "mega"do not have WiFi capability.
If you wish to communicate with the system from the house, take a look at the Wemos D1R2.
Form factor and programming language is the same as Arduino but it has WiFi connectivity.
It even uses the Arduino programming software.
Costs around $10
The big difference with the Wemos is that it's pins are all 3.3vdc (like the raspberry Pi) unlike the Arduino which is 5vdc.
Buy local from Amazon. (As you know, ... EBay is not shipping from the Asia at the moment)
Make sure it's the Wemos D1 R2 . The older Wemos D1 has been phased out but there may still be some old inventory being sold.

cheers,
