ROCKET FUEL SUBMIITED @ L.J.I.E.T.pdf (Size: 429.22 KB / Downloads: 155) Abstract Gasolines sold at our service stations typically have an octane rating between about 87 & 93, & fuels of such octane values are satisfactory for most automotive engines. However for high performance engines in particular, fuels of even higher octane ratings are required. Octane is a measure of a gasoline’s antiknock performance – its ability to resist knocking, which is a metallic rattling or pinging sound that results from uncontrolled combustion in the engine’s cylinders. It may prevent engine damage. If a gasoline is used with too low of an octane rating than is required by an engine, then engine knock may result. Heavy and prolonged knocking or pinging may cause power loss and may damage the engine. As is well known, the production of fuels of progressively higher octane values is progressively more difficult to achieve. In particular, fuels of octane value at or above 100 are highly desired & correspondingly the most difficult to produce, particularly for unleaded fuels. Usage of such regular fuels in our S.I. , I.C. Engines thus reduces the performance of the engine & hence doesn’t give required C.R. & thereby exhausts that pollute the environment. The following paper refers to a fuel additive component TOLUENE that helps to increase the octane rating of the fuel & thereby increasing C.R. to the required level in the engine. |
