"The dieseling was only a side effect of making the ethanol impure and undrinkable," Charlotte maintained.

Dieseling is so-named because it is similar in appearance to how diesel engines operate: by firing without a spark.

Dieseling is not nearly as common as it once was, because it most commonly occurs in engines equipped with carburetors.

Such an increased interest in diesel has resulted in slow but steady "dieseling" of the automobile fleet in the countries affected, sparking concerns in certain authorities about the harmful effects of diesel.
