Application of biomass gasification as fuel for four-stroke otto engines

Visoka cijena fosilnih goriva i njihov utjecaj na okoliš zahtijevaju alternativne izvore goriva. Jedan od pristupačnijih, relativno jeftinih i obnovljivih izvora energije je biomasa. Biomasa se može koristiti kao gorivo za pogon motora s unutarnjim izgaranjem na način da se pretvori u plin, a taj proces se naziva rasplinjavanje. Cilj ovog istraživanja je dokazati mogućnost upotrebe sinteznog plina dobivenog rasplinjavanjem biomase za pogon motora s unutarnjim izgaranjem i izmjeriti snagu motora pogonjenog na benzin i sintezni plin. Za ovo istraživanje korišten je četverotaktni Otto motor snage 2.5 kW i zapremine 148 cm3. Za mjerenje snage izabrana je elektromagnetska kočnica mjerne snage do 10 kW. Rezultati istraživanja pokazuju da je moguće koristiti sintezni plin, ali uz ostvarenje 30% snage izmjerene pogonom na benzin.The high cost of fossil fuels and their impact on the environment require alternative fuel sources. Source that stand out as the most affordable, relatively cheap and renewable is biomass energy. Biomass can be used as fuel to power internal combustion engines by converting it to gas in the process which is called gasification. The aim of this study is to prove the possibility of using synthetic gas obtained by gasification of biomass to power internal combustion engines and to measure the power of gasoline and synthesis gas engines. For this research, a four-stroke Otto engine with a power of 2.5 kw and a volume of 148 cm3 was used. The electromagnetic brake with a measuring power of up to 10 kW was chosen for the power measurement. The results of the research show that the selected engine had only 30% of the declared power and it is possible to use synthetic gas, but with the achievement of 30% of the measured power with a gasoline
