Gonna get a diesel in July

JHMEG

Looking at a 2004 or 2005 model, with an Isuzu 1.7 TD. Really dirty yoke too, it's not even Euro IV. I pity all the fsckers driving behind me.

However there is light at the end of the tunnel for all my passive smoking fellow motorists. I plan on using a bit of SVO or biodiesel. In fact I'd like to use as little benson & hedges diesel as possible. So... what I'd like to know is has anyone any comments to make about this engine, and in particular using it on veg oil or biodiesel?

Trust me - in a 1.7 TD ... there'll be nobdy behind you - they'll all be infront!

Very rough and agricultural engines i heard, very noisy too . - The complete opposite to hondas own diesel engines.

Will it be a honda civic with an isuzu engine you'll be going for?

2005? Common rail therefore forget biodiesel or SVO.

I would have thought the only thing you would use a diesel for is target practice!

Check the type of injector pump, they came with both bosch and lucas, the bosch one is the one to go for, Lucas doesn't like veg oil without major modification that requires a full stripdown. The problem with that vintage bosch pump is that it will probably have electronic control, this is pretty rudamentary, it's just a linear actuator that moves a sleeve which controls the proportion of diesel that's sent to the injector v's what's sent to the return line. Diesel acts to lubricate the rotor in the pump but the problem arises under breaking conditions when it cuts the fuel supply completely which starves the rotor of lubricant, the residual diesel under nornal conditions will wick around the rotor to provide lubrication but the higher viscosity veggie oil will not get around the rotor without the applied pressure of the piston. There are a few possible solutions, one is to hack the firmware controlling the actuator and the other is to put a mechanical stop in somewhere to prevent the sleeve cutting off the fuel supply completely or finally you could put a small hole in the side of the sleeve so some fuel always gets through.
Whatever solution you go for, you'll need to preheat the veg oil using an inline heater on the fuel line and/or a heater in the tank. These can be heat exchangers with coolant running through them in whcih case you'll need a second smaller tank for regular diesel for the start up and shut down or alternatively they could be electrical which could potentially work on a single tank. If you want to do the best job possible, get an elsbett kit.

edit... all this assumes it's not common rail, if it is, forget it.

All the Civic diesels with that engine are common rail afaik. You'll have to get yourself an Astra or a Vectra so

And it will need to be much older than 2004/2005

Yeah, the EP2 1.7 CTDi Civic, is common rail. You'll need to go back further and get yourself the 6th gen 5 door 2.0 diesel to stick with Honda. Or you could just bite the bullet and get a flexifuel Ford Focus.

Didn't Opel still have a non common rail 1.7 diesel back then for the Corsa, using that Isuzu engine? The 1.7 DTI or something like that?

Mmmm.

Modern 1.7 Isuzu is common rail, but two things:
a) there are conversion kits available.
b) I also reckon it's possible to run veg oil in a common rail without a conversion.. This guy is running filtered chip fat in his Opel Meriva 1.7 TD.

Seems to me that there are a lot of half truths out there.

You're brave man. You'll need a twin tank setup at the very least. Keep us posted on your exploits.

Yep, same engine was used all over the opel/Vaux range in the mid 90's, think it even carried over to the 97/98 model vectra. Was used in the Astra, Astravan, and vectra B as far as I know. I also know those engines were able to put up a lot of milage without much hassel.
