context: Common-rail fueling systems, a much more recent innovation, have enabled a new order of diesel control.
answer_0: Altogether, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_1: Previously, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_2: Usually, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_3: Regardless, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_4: This, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_5: Frankly, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_6: Namely, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_7: Elsewhere, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_8: Meantime, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
answer_9: Mostly, with primary fuel pumps delivering fuel to each cylinder, engine operation - and the efficiency of the combustion process - often was highly dependent on engine speed.
