What it is telling you is that diesel is not going to be a fuel of the
near future for light vehicles. Particulate emissions are killing off
the diesel engine. The interesting corollary to this however is that
GDI, the supposed future of the petrol engine, suffers from the same
particulate emission albeit with petrol as fuel instead of diesel.

GDI engines are already suffering from intake system coking.
Prepare for interesting times in the car industry.
