LC76 / VDJ76 cruiser - does it have a DPF

"I have asked a Toyota dealer who did not seem to have a clue what a DPF is."...scarey.
That's why they get the big bucks (*rolls eyes*).

I could be wrong but I don't believe any of the Toyotas sold in Australia are fitted with a DPF at this point in time - they do have a cat but not the additional DPF. All diesel vehicles manufactured to Euro5 standards do have a DPF eg the Navara D40, the range of Mitsubishi vehiclesand others of this ilk. Gotta say I now have >50000km on my D40 and no problem with the DPF. The main problem is that people don't read their owner manuals and don't understand how the DPF works....especially consistent slow ie<1800rpm running and the need to lift this periodically to complete a burn.
I would think that it is only a matter of time before all diesel vehicles are fitted with a DPF. These are not new folks they have be fitted to some of the heavy vehicles running around since the late 1980s early 1990s.

They have a diesel particulant filter to comply with Euro4 emission compliance as do all diesel and petrol engines certified to comply with that spec

I have a toyota VDJ 79 with the new V8 and a little research has shown that Toyota has looked into emission control to where test have show the new V8 also exceed euro cert 5 compliance.

The V8 exhaust has two Catalytic converters. Toyota identifies its catalysts as 'diesel oxidation catalyst' system which means it traps available oxygen from exhaust emissions and then uses this to burn soot particles. Refer to this article on 'Diesel emission control: Catalytic filters for particulate removal.'

iopscience.iop.org/1468-6996/8/1-2/A17/pdf/STAM_8_1-2_A17.pdf

The new V8 engine also utilises a water cooled ERG system which reduces the burn temperature thus greatly reducing the chemicals that form much of the exhaust particles.

Next a quote from toyota specs sheet

"The second generation common rail technology also allows for a quieter combustion process enabling two individual pilot injection strokes of around 1 mm³ quantity ahead of the normal injection stroke, all of which happens within a few milliseconds."

The use of the new (very expensive) injectors and their very fine tolerances means there is very little waste in diesel fuel being individually injected to each cyclinder depending on the vast array of sensor feedback.

It doesn't have a Diesel Particulate filter as such because Toyota has incorporated a system that regenerates itself and burns off the particulates that are formed.

I am not a mechanic but have just had a look around the net for some answers because your question intrigued me as I felt Toyota must have looked at this.

Whilst we on this technical stuff does any have or know of the availability of workshop manuals of the VDJ 70 series or just the engine V8 4.5 lt diesel. Thanks in advance
