A4 TDi v 320d

[Fox]

Congratulations on the purchase, although I must say I'm staggered at how these hold onto their values, does seem rather a lot for a car that old!

Hope it's good to you.

[Rave]

and as has been said, it's common rail (which seems to be back in fashion after the PD fad)

It can't be- the first common rail engines weren't introduced until 1997; VW didn't adopt common rail until this year or last. Pumpe Düse didn't appear until about the year 2000.

[J4MES]

it's a 1997 car ... but your're right - it's not common rail;

it uses an electronically controlled Bosch VP 37 distributor-type injection pump which is mounted on the front of the engine and driven by the timing belt. This delivers fuel to separate injectors at each cylinder through high-pressure steel fuel lines. This system is used on the 1.9 litre 4-cylinder engines of both 90hp and 110hp, and is also used on the 2.5 litre 5-cylinder engine as well as the 2.5 litre V6 of 150hp. The latter engines have the injection pump mounted elsewhere on the engine but they work the same way. Inside the distributor-type pump, fuel is first drawn into a vane pump which pressurizes the pump housing to a low pressure, which is below the injection pressure. A single plunger rotates together with the input shaft but is also spring-loaded against a cam, so that the plunger moves in and out of a cylinder with ports in it. When the plunger is pulled back, fuel enters the cylinder via the fuel cutoff solenoid valve which is visible on top of the pump housing with a single wire going to it. When the plunger advances (4 times per plunger revolution in the case of a 4-cylinder engine), fuel is delivered through a passage in the plunger to whichever fuel line aligns with a port in the rotating plunger, thus fuel is delivered to the appropriate cylinders in sequence. Eventually, on each stroke, the plunger advances far enough that another port in the plunger is uncovered by the cutoff sleeve and any remaining fuel behind the plunger is bypassed rather than being injected into the cylinders. This sleeve is positioned in and out along the plunger so as to vary the quantity of fuel being injected, as directed by the engine controls. Injection timing is varied by rotating the cam profile that the plunger is pressed against; this is done by a small hydraulic cylinder controlled by a solenoid valve located on the bottom of the injection pump housing. Excess fuel which is not delivered to the engine is returned to the fuel tank through a return line.
Each injector contains a spring-loaded plunger which opens when the fuel pressure reaches a certain amount. The plunger then uncovers 5 injection orifices of extremely small diameter. The preload springs operate in two stages so that the initial injection occurs at a lower pressure, followed by the main part of the fuel at a higher pressure. This results in the fuel igniting progressively, thus reducing the noise level of the engine.

But despite that it still sounds like a taxi and is slow

Only joshing with you - look after it and it'll look after you.

[J4MES]

there's nowt nice about the noise it makes, that's true! but it's done 450 miles on it's first tank of fuel, and hasn't got to the 1/4 mark yet...

[Konan555]

Worth noting, change the belt WELL before the service interval. They can let go before time and it's not something you want to pay a dub dealer to sort!

[badass]

-snip-

Pretty much the same as any mechanical injection diesel engine then

Good good, saves someone else the misery

quite. sounds bog-standard to me - the figures for mpg/power aren't good enough to be anything fancy. plus side is that they cost less when they go wrong - reason i took a mondie over a vectra/406..

450 miles might look like less than 1/4 tank, but i betcha don't get more than 800 out of it.. mine still nestles on the top marker after 100 miles, but after 700 the light is on..

the 5pot unit was also used in the volvo 850 - was quite a refined engine for the time, but didnt sell well as its still too noisy/gruff compared to it's petrol counterparts.. it wasnt really till direct injection took over that derv exec cars really took off..

[redtony]

a4 ftw

[J4MES]

it wasnt really till direct injection took over that derv exec cars really took off..

iirc direct injection has been around a while

[J4MES]

back to square 1... the A4 is 'too big' i.e. it's an estate which her indoors doesn't like ('but it's an Avant, a lifestyle estate')...

looks like only a Golf IV will do tbh, or a cheap A4 saloon...
