JB,
As Julian says, keep to the stuff that has been made into an ester. I
have worked on the technical side of this production with some very
technical German consultants (Gopa consult) trying to solve some post
Chernobyl problems. The neat veg oil mixed with diesel can cause
gumming and all sorts of problems with valve stems and piston rings
etc. Short term seems OK, long term is bad.
Common rail.
No we don't have it in the 80. But its now the common standard for
new diesels. On your 80 the injector pump squeezes fuel down the line
in separate pulses to each of the 6 injectors on the engine, which is
all timed and powered from the crankshaft. With common rail, one pump
provides a continuous high pressure fuel line to a manifold along the
side of the head - the 'common rail'. So with a constant high
pressure of fuel right in the cylinder head, the injectors are in
fact electric valves that let the high pressure fuel through to the
cylinders in sequence. So the fuel system relies on a very reliable
electric/electronic engine management system. Ask the owner of a new
Hyundai Galloper what they think about them ! Thankfully the Toyota
system in the newer models works well. But the BMW TD5 in the LR
models is not so successful. So much so that the British army only
has the old 300TDi engine fitted with 'normal' injection in new vehicles.
