Abstract
Authors summarize the results they obtained at the thermal
engines laboratory of the high engineering college of
Barcelona.
Two lines were followed; The first devoted to the research of
the effects of the addition of organic products to conventional
petrols in view to improve their behaviour and to go in search of
fuels not derived from oil for OTTO-cycle engines, the best results
having been obtained with mixes of conventional fuels with methanol
and propanone; on the other hand, mixes of butane, methanol,
ciclohexane and toluene were tested, obtaining excellent results as
well from the point of view of the octane number as well as from
that of horsepower and low contamination index.
Now research is carried forward in which mixes of standard
petrol component fractions with methanol and eventually with other
ingredients are tested.
These non conventional fuels have been tested on engines on the
test bed, the exhaust gases having been submitted to analysis. The
octane number, the stability under low temperatures, the
distillation curve, the vapour tension, etc., have been determined
as well.
Finally the improvement on pollution has been determined on
vehicles tested operating under the europa cycle.
The engines as well as the vehicles were completely standard and
for this reason, the achievable improvements could be arrivd at
with only fitting specially projected carburettors to same.
