Comparative performance study of spark ignition engines burning alcohols, gasoline, and alcohol-gasoline blends

摘要: In recent years it has been clear that the reserves of oil, from which petrol is refined, are becoming limited. order to conserve these stocks and minimize motoring costs as price dwindling oil resources escalates, it's obviously desirable improve thermal efficiency spark ignition engine. There also obvious benefits be obtained making engines run efficiently on alternative fuel, (non-crude based fuel). It claimed hydrogen an ideal fuel for internal combustion engine certainly causes little pollution, but difficult store, high in price, burn without knocking backfiring. These problems arise because very wide flammability limits flame velocity hydrogen. Alcohols used additive or substitute gasoline could immediately help solve both energy pollution problems. An experimental tests were carried out at Mansoura University Laboratories using a small single cylinder SIE, fully instrumented measure performance. The was fueled with pure methonol, ethonol, methanol blends gasaline ethanol blends. results showed principle, kechnological aspectsmore » possible use alcohols extender alcohol's gasoline, automobiles.
