EXPERIMENTAL INVESTIGATIONS ON DICI METHANOL (WITH ADDITIVES) FUELLED WITH CERAMIC HOT SURFACE IGNITION SYSTEM

Abstract

The concept of using alcohol fuels as alternatives to diesel fuel in CI engines is a recent one. The scarcity of transportation petroleum fuels leads to the recognition of alcohol as a preferable replacement. Methanol is an excellent combustion engine fuel with a high octane rating and clean burning characteristics to be used in SI engines. It is used as a fuel primarily as M85 (a mixture of 85% hydrocarbons) or as neat Methanol, M100 (100% ethanol. It has poor self ignition characteristic; therefore, its use in diesel engines requires a means for providing ignition. For single fuel engines this entails use of a spark plug or Ceramic hot, fuel additive ignition improvers, or enhanced auto-ignition through the use of exhaust gas re-circulation. The effect of additives mixed in Methanol is studied in the best suited coating Ceramic hot surface ignition engine, in order to get higher performance.
