  The first productioncar running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat. ETHANOL Ethanol is a renewable, domestically produced alcohol fuel made From plant material, such as corn, sugar cane, or grasses. Using ethanol can reduce oil dependence and greenhouse gas (GHG) emissions. Ethanol fuel use in the U.S. has increased dramatically from about 1.7 billion gallons in 2001 to about 16.4 billion in 2016 Ethanol is also known as ethyl alcohol. It’s the alcohol in beer, wine, rum, vodka, etc. Ethanol was used to fuel some of the first automobiles…

  Alternate fuels…. ETHANOL  Alcohol-basedalternative fuel produced by fermenting and distilling starch crops or cellulose  Most commonly used to increase octane and improve the emissions quality of gasoline.  Can be blended with gasoline to create E85, a blend of 85% ethanol and 15% gasoline.(FLEX FUEL)  An excellent, clean-burning fuel, has a higher octane rating (over 100) and burns cooler than gasoline. High ethanol blends present a problem to achieve enough vapor pressure for the fuel to evaporate and spark the ignition during cold weather

  Chemical Formula: CH3OH, Density: 792 kg/m, Melting point: -97.6 °C Methanol Of all the fuel being considered as an alternate to gasoline, methanol is one of the most promising and experienced major research and development.  Methanol, also known as wood alcohol, can be used as an alternative fuel in flexible fuel vehicles that run on M85  The benefits include lower emissions, higher performance, and lower risk of flammability than gasoline  Methanol can easily be made into hydrogen for hydrogen fuel cell vehicles in the future.  Methanol is extremely corrosive, requiring special materials for delivery and storage.

  VEGETABLE OIL  RUDOLFDIESEL Designed a diesel engine in 1984 to run on peanut oil.  The use of vegetable oils for engine fuel may seem insignificant today. But such oils may become in the course of time as important as petroleum an coal tar products of the present time. -An Extract from Diesel’s speech in 1912

   Most dieselcar engines are suitable for the use of straight vegetable oil (SVO), also commonly called pure plant oil (PPO), with certain modifications. Principally, the viscosity and surface tension of the SVO/PPO must be reduced by preheating it, typically by using waste heat from the engine or electricity, otherwise poor atomization, incomplete combustion and carbonization may result. One common solution is to add a heat exchanger and an additional fuel tank for the petrodiesel or biodiesel blend and to switch between this additional tank and the main tank of SVO/PPO. The engine is started on diesel, switched over to vegetable oil as soon as it is warmed up and switched back to diesel shortly before being switched off to ensure that no vegetable oil remains in the engine or fuel lines when it is started from cold again

  BIODIESEL  Biodiesel isa domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant greases.  Biodiesel is safe, biodegradable, and reduces air pollutants such as particulates, carbon monoxide, hydrocarbons, and air toxics.  Biodiesel can also be used in its pure form but it may require certain engine modifications to avoid maintenance and performance problems and may not be suitable for wintertime use.  Need to heat storage tanks in colder climates to prevent the fuel from gelling

  IMPORTANCE OF BIODIESEL •Environmental friendly • Clean burning • Renewable fuel • No engine modification • Increase in engine life • Biodegradable and non-toxic • Easy to handle and store • Complete CO2 cycle • Sulphur free

  •A potentially emissions-freealternative fuel produced from domestic resources. Not widely used today as a transportation fuel Advantages  Emits only water vapour, assuming there is no leakage of hydrogen gas  It can store up to 3x as much energy as conventional natural gas.  Produced domestically.  Environmentally friendly. Disadvantages  It still costs a considerable amount of money to run a hydrogen vehicle  Dangerous

  It is muchsafer than other fuels in the event of a spill, because natural gas is lighter than air and disperses quickly when released  COMPRESSED NATURAL GAS
• 21.
  Advantages  it canbe efficiently and safely stored.  more environmentally friendly due to its low emissions after burning.  most of the natural reserves of natural gas field are underutilized.  Improve lubrication because the cylinders are not washed by petrol excess Disadvantages  still does create greenhouse gas emissions.  highly volatile and can be dangerous is handled or transported carelessly.  they aren't as roomy as gasoline cars.  higher overall costs of a natural-gas vehicle compared to a gasoline- powered car.
