Diesel tech.
I've been reading up on diesels and have learned about the 3 modern methods for direct injection. If someone know the pros and cons and/or other methods please join in.
1)Distributer pump- Has one pump and a valve that directs the fuel to each cylinder
2)Common rail- Has one super high pressure pump that supplys fuel to each cylinder all the time (I think?).
3) The last method is when each cylinder has its own pump.

Hi Lakedude,
Quite a good read HERE with regards to RichC's reply - a comparison between Common Rail and PD.
I am not so sure that this statement is true about the Common Rail system however;
"combustion noise is reduced to almost petrol engine levels"
Well, it certainly doesn't apply to my Civic at tickover anyway...
I am yet to hear a quiet diesel at low RPM's - however I haven't had the opportunity to listen to the new i-CTDi unit in the Accord at close hand yet.

Hi Stoner,
The new Toyota Avensis diesel (177bhp) is meant to be a good bit quieter than the petrol version - but how much of that is down to hiding all the clatter with extra sound insulation is anyone's guess!
