B200E and B230E are fitted with Bosch K-Jetronic mechanical fuel injection. F engines (in the UK market) are fitted with Bosch LH2.4-jetronic electronic fuel injection. There are also other subtle differences, such as the camshaft fitted (E engines have a more aggressive cam)
the 'B' at the start stands for 'benzin' (swedish for petrol), followed by the displacement in decilitres (200 = 2.0, 230 = 2.3), and the suffix denotes the specific engine version. as well as F and E, you'll find: K (downdraft carb, on a 240 it's the undesirable solex carb, on a 740 it's a pierburg) A (sidedraft carb) FX (high-performance version of F, super rare as the 'FX' kit was sold as a dealer-fit upgrade by Volvo) FB (updated version of FX engine fitted to 940), ET (early version of turbo engine fitted to 740, Bosch Motronic fuel injection) FT (turbo engine fitted to 740/940, Bosch LH2.4 jetronic injection) FK (low-pressure turbo version of FT) FD (F engine with extra emissions controls including pulsair exhaust gas recucrulation system).

I'm more than happy with my Solex Cisac. What's your problem with it?

1992 Torslanda Estate. 2.0 litre engine. 24 MPG first tankfull, but it was leaking from sender pipe & had been stood for 2 years. Worked it out the other day, leak fixed & 1000 miles on, about 31 MPG. That's a mix of country lanes & dual carriageway, driven like an "old man in a Volvo". Happy with that, may not be the best, but then my old Land Rover doesn't get much better than 20 MPG. Which puts it in perspective.

My '93 Torslander (B200E) averaged 29.98 MPG over 12,000 miles. My '89 GLT (B230E, K Jetronic) is averaging 26.74 MPG over 4,400 miles, despite having dragged 13 tons of building materials up a steep mountain road in first gear during this period. Difficult to top 30MPG on the motorway though.

All the problems can be fixed by upgrading to a carb that's still supported by the manufacturer, and binning all the extraneous equipment fitted as a half-baked fix to improve emissions. The 80s were a dark, dark time in engine design.

Personally none, but when I was a mechanic I had 2 customers who had 240GLE estates, both with the B230K. Both carbs were well past their use-by date and required constant attention. One car was eventually converted to use a weber carb at some expense. The other had it's carb semi-reconditioned by cobbling together parts from three carbs (the original, the one from the second car, and one I bought from clifford pope on here) which produced a carb which functioned well enough to keep it going for another 2 years until it was scrapped for other reasons. At no point were we able so source replacement parts for the carb from any source in the UK or europe.
I'm sure some have solex-cisac carbs that work, but I personally dislike them for the problems they've caused me.

On my '79 245 B21a, m46 overdrive, and running on LPG, I've been getting 22mpg in winter- heavy traffic commuting- 20mph average; bumper to bumper for 10 miles, then hilly south-downs A/B roads for 10 miles- then driving in circles for 10 minutes to find free Volvo sized parking in Eastbourne.
I'd say that's pretty much as 'worst case' driving as you can get outside of London. On a run, I tend to get about 25mpg on gas, but that's averaging 75mph, and a few long- (30-45minute stopped) motorway queues. I've never had the opportunity to test it 'tank to tank' at anything like an unclogged highway. So we're basically talking Fiat Panda type fuel bills in something the size and shape of a government office block. |
