Just because an engine is built in Brazil and exported to other markets doesn't mean the domestic market and export market engines are the same. An engine line can run multiple variations of the base engine.
Recently I worked on a project introducing Euro V engines into the Central and South American market. The engine is manufactured in our Brazilian plant and is currently used in the Brazilian market as well as Asia and Africa. It is the same base engine that was first used in Europe and the USA in the 1990's before it was phased out by emission regulations. However, even though they are maybe 95% the same they are still have significant hardware differences. Yes, the changes a small when making the engine but would be very expensive to retrofit after the fact.
There is a huge difference between essentially the same and actually the same when it comes to emission testing.
