Abstract
Various systems and methods are provided for adjusting operating parameters of an internal combustion engine. In one example, a system may include adjusting an amount of advance of a fuel injection timing of a plurality of fuel injectors of an internal combustion engine relative to top dead center (TDC) responsive to engine output demand, where, as the engine output demand increases, the amount of advance first decreases and then increases. In this way, an amount of vehicle emissions may be decreased while an amount of fuel consumption is decreased.
