Abstract
The use of gasoline - bioethanol mixtures is examined in an internal combustion
small displacement engine that is used for the operation of a small alternative
electrical generator. Different mixtures of gasoline-ethanol (lo%, 20%, 30% and
40%) were used as fuel. The engine functioned at idle and under full load
(IKW). During the tests, the gas emissions (CO, HC) and the fuel consumption
were constantly measured for every mixture separately. Test showed a
considerable decrease of gas emissions roughly proportional to the percentage of
ethanol in the fuel mixture. No adverse effects on the engine were noted.
1 Introduction
Atmospheric pollution is one of the major environmental problems of public
concern. The pollutants that exist in the air mainly harm humans causing
respiratory diseases
