Actually, the primary objective of the current research was to
quantify the limits of methanol substitution percent over a wide
range of engine loads (loads from 6% to 100%). Consequently, for
the dual fuel experiments, the engine started with 6% of full load
with neat diesel, then an effort was made to keep the pilot amount
of diesel fuel constant. The power output of the engine was
adjusted by the amount of methanol supplied through the intake
port until the DMDF engine reached its full load or operating limits,
such as knock and misfire. Then same procedure was conducted at
