The new generation CRDI engines uses higher fuel pressures that no clogging would occur in the nozzles. Compare to the first generation CRDI, the fuel pressure is about 3 times higher. So clogging nozzles is not a problem.
Unfortunately, the D-4D does not have the maintenance free particulate filter na standard equipment sa european diesels. With an EGR system soot will accumulate sa intake manifold. Plus a PCV that doesn't have an oil separator, vaporized oil could enter the intake manifold.
This could be the reason why the power of the D-4D engine might have been toned down to 102ps. This would lower the tendency to have vaporized oil going into the manifold. Less HP less Blow by gasses entering the crankcase then less chances of vaporizing the oil to go out with the PCV.
Nevertheless, the D-4D has a lot of potential in further increasing HP by adding an intercooler.
INNOVA for me.
