  2. Antiknock agent - Wikipedia

    en.wikipedia.org/wiki/Antiknock_agent

    Antiknock agent. An antiknock agent is a gasoline additive used to reduce engine knocking and increase the fuel's octane rating by raising the temperature and pressure at which auto-ignition occurs. The mixture known as gasoline or petrol, when used in high compression internal combustion engines, has a tendency to knock (also called "pinging ...

  3. Tetraethyllead - Wikipedia

    en.wikipedia.org/wiki/Tetraethyllead

    Tetraethyllead (commonly styled tetraethyl lead), abbreviated TEL, is an organolead compound with the formula Pb (C 2 H 5) 4. It was widely used as a fuel additive for much of the 20th century, first being mixed with gasoline beginning in the 1920s. This "leaded gasoline" had an increased octane rating that allowed engine compression to be ...

  4. Ethanol fuel - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel

    The Saab 9-3 SportCombi BioPower was the second E85 flexifuel model introduced by Saab in the Swedish market. Ethanol fuel is fuel containing ethyl alcohol, the same type of alcohol as found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. Several common ethanol fuel mixtures are in use ...

  5. Common ethanol fuel mixtures - Wikipedia

    en.wikipedia.org/wiki/Common_ethanol_fuel_mixtures

    Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles. Anhydrous ethanol can be blended with gasoline (petrol ...

  6. Tractor vaporising oil - Wikipedia

    en.wikipedia.org/wiki/Tractor_vaporising_oil

    Tractor vaporising oil. Tractor vaporising oil (TVO) is a fuel for petrol-paraffin engines. It is seldom made or used today. In the United Kingdom and Australia, after the Second World War, it was commonly used for tractors until diesel engines became commonplace, especially from the 1960s onward. In Australian English it was known as power ...

  7. Petrol engine - Wikipedia

    en.wikipedia.org/wiki/Petrol_engine

    Petrol engine. A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85). Most petrol engines use spark ignition, unlike diesel engines ...

  9. Methanol fuel - Wikipedia

    en.wikipedia.org/wiki/Methanol_fuel

    Methanol fuel. Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
