What are the various alternative fuels for SI and CI engines?

The representative alternative fuels for SI engines include compressed natural gas (CNG), hydrogen (H2) liquefied petroleum gas (LPG), and alcohol fuels (methanol and ethanol); while for CI engines, they include biodiesel, di-methyl ether (DME), and jet propellent-8 (JP-8).

What are the various alternative fuels?

Alternative Fuel Options

  • Alcohols, e.g., ethanol and methanol.
  • Biomass-based diesel fuels. Biodiesel (fatty acid methyl esters, FAME) Renewable hydrocarbon diesel.
  • Methane, e.g., natural gas, biogas and synthetic natural gas (SNG)
  • Hydrogen.
  • Synthetic fuels.
  • Dimethyl ether (DME) and other heavier ethers.
  • Ammonia.

What are the different kinds of fuels used in an IC engine?

The most common alternative fuels for SI engines are ethanol in blends with gasoline as well as compressed natural gas (CNG) , liquefied natural gas (LNG) , and liquefied petroleum gas (LPG) . Biodiesel, synthetic diesel, green diesel, and DME are the most common alternative fuels for CI engines.

Which of the following is the best fuel for SI engine?

So, ethanol has been used widely as alternative fuel in internal combustion engines. The octane number of ethanol is higher than the octane number of the gasoline. The high octane number of ethanol allows the use of ethanol as fuel in an SI engine with a higher compression ratio [40].

Which is the most preferred SI engine fuel?

engines fuel most preferred are paraffins and for S.I. engines fuel most preferred are aromatics.

Which fuel is used in CI engine?

ICEs are typically powered by fossil fuels like natural gas or petroleum products such as gasoline, diesel fuel or fuel oil. Renewable fuels like biodiesel are used in compression ignition (CI) engines and bioethanol or ETBE (ethyl tert-butyl ether) produced from bioethanol in spark ignition (SI) engines.
