Rest In Peace, old friend, your work is finished.....

If you want ON or OFF the DIESEL ”KnOcK” LIST just FReepmail me.....

This is a fairly HIGH VOLUME ping list on some days.....

If the effort was deferred to produce the maximum efficiency from and engine instead of emissions would it result in less emissions from less fuel being consumed?

Exhaust gas recirculation has been used in gasoline engines since the 60’s or 70’s to reduce NOx. Guess I’m surprised it hasn’t been used heretofore on engines using genuine diesel fuel.

I think compression ignition engines are going to be one wave of the future. They’re a natural for their splendid efficiency, hence MPG. Any efforts to improve the exhaust quality are welcome indeed.
