an update on this misery
firstly I found this document
http://web-cache.stream.ne.jp/www09/toyota-catalog/pdf/hiace-1/hiace-1_199808.pdf which is a brochure for a 1998 Hiace.
The relevant bit is here
The columns relevant to this vehicle is KZH110 which has weights
1820/1830 which I assume is the empty vehicle weight and 2370/2380 which is gross vehicle weight. I have no idea what the 10kg weight differences in each case is for. Maybe auto/manual transmission?
In parallel I have a nonsensical reply from Toyota in Japan saying that this vehicle complies with 1994 Japanese regulations with these figures.
NOx:0.50g/km
HC:0.40g/km
CO:2.10g/km
PM:0.2g/km
According to a doc "Global Motor Vehicle Emissions Regulations, Walsh, 6/3/2005 in table 42 it says that these are the 1994 limits for a vehicle <1265kg which clearly the Hiace is not.
Unfortunately it also says that the PM limit of 0.08 (stricter than Euro 3) for 1997/1998 was not applied to existing models until 1.9.99 (not sure it that means 1st Sept or 9th Jan). As this vehicle was registered in Japan in 1998 this won't help.
I am sure that the Hiace was sold in Japan after 1999 with the 1KZ-TE engine wasn't it?
In short Toyota is not going to help, as they can't even identify the correct weight table in the emissions regs and TFLs requirement for a letter from Toyota is unrealistic.
The only angle left the fact (well I need to verify it) that the Prado is Euro 3 compliant with the 1KZ-TE engine. This is going to be a nightmare.
So how do I verify that the the Prado with that engine is Euro 3 ?
