In the operation of SI engines, alternative biomass fuels such as rice husk can be
utilized. This will contribute limit the consumption of fossil fuels. The dual-fuel
approach can also be employed on SI engines. One of the solutions that can be employed
in dual-fuel SI engines with gasoline is producer gas, a flammable gas created by
biomass gasification. However, the numerous methods of incorporating gases into SI
engines necessitate substantial investigation. In this study, producer gas and gasoline
are combined and fed into an SI engine. The dual fuel is used to power the
single-cylinder SI engine. The most optimal operation of the Y-shaped mixing chamber is
investigated. Experiments were conducted to determine the optimal air-producer gas ratio
values based on the SI engine's ability to operate in time at idle. Two variables were
chosen as inputs: air producer gas ratio and fuel mixture percentage. According to the
study's findings, an air-producer-gas ratio of 1.5:1 with 50% gasoline results in better
mixing. The single-cylinder SI engine has been running smoothly and longer than other
parameters without knocking.
