Abstract
Reduction of toxic compound emissions to the atmosphere is currently the main operating criterion for combustion engines. One possible
method for lowering the emissions by combustion engines involves using biogas as an alternative fuel. Biogas can be obtained from
different raw materials using different technologies. Therefore, the content of methane, the main combustible biogas component, varies
widely.
Biogas can be used as fuel directly for feeding spark-ignition engines. Biogas use is more difficult for compression-ignition engines
because of the quite high methane auto-ignition temperature. Therefore, the use of biogas as fuel for compression-ignition engines
requires the injection of a small liquid fuel charge into the combustion chamber, whose aim is to cause the ignition of the produced
air/biogas mixture.
This paper presents the preliminary results of a study on toxic compound emissions by a dual-fuel compression ignition engine with the
main fuel charge fed as biogas.
Keywords: CI engine; biogas; methane; toxic emission.
