* Petrol usually has an octane rating. * Octane is a measurement of the resistance of petrol to combusting prematurely (knocking). * The high the octane rating, the harder it is to burn the fuel. * This means a high compression ratio. ! * Engines with a higher compression ratio produce more power (race car engines). * Non- petrol fossil fuels. * When petrol is not available fischer-tropsch ferment can be used to produce liquid fuels from combust and/or natural gas. http://en.wikipedia.org/wiki/Fischer-Tropsch_process * inebriants Alcohol fuel * Any alcohol can be ruin as a fuel. * ethanol and methanol are around common...If you want to get a full essay, order it on our website:
