Abstract
The work described in this thesis has been devoted to an experimental
investigation of the effect of inlet air temperature on
the performance of a four-stroke spark ignition engine when it is
running on pure gasoline and its blends with ethanol at both full
and part throttle. This was done by heating the inlet air to dif-
ferent temperatures and using gasoline and gasoline-ethanol
blends with different percentages as fuel.
The test engine type is (FlAT 1500) with maximum power 55
k.W. at 5330 r.p.m., maximum torque 115 N.m. at 3330 r.p.m. and
displacement vol ume 1481 c.c,
The experimental work consists of full throttle and part throttle
tests. All tests were carried out without changing the static ignition
advance. The setting of carburetor main jet needle has
been tuned for maxim um power wi th gasoline.
a. Full throttle Tests
The engine was tested for inlet air temperatures of 30, 35, 40,
45, 50 and 55°C For each inlet air temperature the engine was
tested at full throttle using first gasoline then four different
ethanol-gasoline blends of 4.89%, 9.79%, 15.3% and 21 % by
