Biodiesel Production and Applications

It is well known that acetylene is a high flammable and explosive compound. In comparison with commercial liquid fuels, very wide flammability limits and a low Octane Number have relegated the acetylene into the "iperdetonat" fuels category. Thus, it is impossible to run an internal combustion engine on acetylene without a detonation phenomena control system. The current paper deals with a theoretical and experimental analysis of an internal combustion engine running on acetylene and alcohol. A standard 8 kW spark ignition engine with carburettor was modified with electronic injection control system (ECU) and two standard commercial injectors: one for the acetylene and one for the alcohol. The two injectors were installed using a modified engine intake system. The ECU is able to manage two fuels: acetylene and alcohol. Moreover, an optimization method base on Genetic Algorithms and Neural Networks was used to cerate engine parameters map. Thus, Running an ICE on acetylene and alcohol it is possible to achieve acceptable engine performance and very low pollutant emissions.
