new engines are mostly highpressure Diesels of FSI engines (gas engines
but with gas inyected inside the combusion chamber in a way simmilar
to Diesel engines).

Name some of these new engines, so we can compare what we are talking
about. If you are talking about the ones I am thinking about, the
sequential injection takes place at the intake valve, on the manifold side.
