Straight Vegetable Oil / Re: injector

Vegoil

Check this out its a serious university report on running a lister 6/1 on vegoil with 3 simple modifications.  Personally I think it is flawed.  They make a preheater out of the CS bung to increase the fuel temperature to 90 degC just before it enters the injector.  I dont believe this is of any benefit at all.  They have a thermostat on the engine and they do all their testing when the engine is up to 90 deg C. Not once do they ever do a test without preheating the fuel even when they don't use their fancy preheater they use electric heating on the injector pipe.  How can they know if it makes any difference when they haven't tested it with no preheating?

In their report they increase the injector pressure and adjust the timing. They recommend 15Mpa injector pressure which is 148 atmospheres. This is nearly the same as the injector pressure for the 16/2 engines see excerpt from 1971 Lister manual. They also advance the injection to 25 deg BTDC which again is similar to the 16/1 setting.

Hi Veg

Start spray ignites very earlier, and so the piston is farway from TDC, therfore it will break the least strong piece, in this case alu piston.

Chrome bores CANT have chrome rings, its hard metal work in hard metal. Can you see result of this friction?

Chrome bores need soft rings...

Stay safe.

Hi Stef

3 ball bearing 7€. The nearby retailer had it in stock, so he pass bearings under the door and same did I with payment.

This angle grinder has been refurbish for several times, it has 15 years, and countless hours work. The inside gear case has the brass bushing with some worn.

Stay safe.

Dunno Mike, but my bullshite detector is swinging both ways.

If the guys want to waste pixels slinging crap at each other that's fine by me, what I don't understand is how anyone thinks that quoting a a quote that quotes a quote that's so long no one read it in the first instance is going to reinforce a point of view or a conspiracy that most of us couldn't give a bugger about anyway!

I'm sure there's a site or forum somewhere that would be appreciative, until you you find it, lads, carry on on here, I suspect most of the members on here are old and wise enough not to want to waste one of our few remaining fucks on this sort of drivel.......

Cheers
Stef


Personally of course Stef idgaf
But I suspect it’s a phenomenon caused by lack of a sense of humour & covid-induced Time-onthe-Hands sydrome. A very common one atm

More nice work!

And you repaired the angle grinder rather than throwing it away and buying a new one.....

Stay Safe

Hi Veg

this is a 8/1, wright?

Is the cylinder bore chrome? if so, it cant have a chrome ring because is to hard!

In my point of view this piston was hited by start spray. Its splited at middle line of wrist pine (small end).

Does it have more symptoms?

that knocking sound seems to be early injection point.

Keep giving news, and stay safe.

Yes mikenash.  Yes.  And enjoying it.  I find this site and many of the threads to be a nice start to the morning.  And the snowman18 is right up there as far as the enlightenment factor goes.  I may not agree with many of his reveals but I appreciate his faith in his own views. 

Rant on, brothers.
