摘要:
Various embodiments related to controlling EGR in an engine are disclosed. In one embodiment, a first EGR amount is supplied to a cylinder at a first temperature and a first engine speed and load. Further, at the first engine speed and load, as engine temperature increases from the first temperature to a second temperature, a first fuel amount is injected after exhaust valve closing and before intake valve opening while a second EGR amount is supplied to the cylinder that is greater than the first EGR amount.
