Quick Engine Clarrification Of Age

Hi guys,


My Zetec 2.0L number starts NGA a gap then VD and 5 numbers.
Is the age "VD" so from Burton November 97?

Is a clear photograph ok for IVA testers to define it as the engine age to do emissions too?
Anyone know where I can find the emission values for the engine test and if it has to be CAT of no CAT?


Many thanks all!!!

Hi,

I thought so. What emissions levels does it have to meet? O.5 co2?

For November 1997 it would be:

Fast Idle: (2500 to 3000rpm) CO <= 0.3% - HC <= 200ppm
Lambda between 0.97 and 1.03

Idle: (450 to 1500rpm) CO <=0.5%


However, if the engine number starts NG that would be April 1992, so would be:

CO <= 3.5%
HC <= 1200ppm

Hi guys,

Yeah the first number is NGA and seems to be pointing at November 93 from emails a few years ago from where the engine came from. Could this be a November 93 engine, if so, does it still need a CAT?
