Engine Performance and Emission Characteristics of a Single Cylinder Four Stroke CI Engine in Dual Fuel Mode using Diesel, Karavera (Thevetia Peruviana) Biodiesel and Surahonne (Calophyllum Inophyllum) Biodiesel with CNG
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
Increasing cost of petroleum, rapid growth of industrialization and the global trend of urbanization along with their increasing pollution by replacing existing fuel. The aim of study is to analyze the performance and emission characteristics existing single cylinder four stroke compression ignition (CI) engine converted into dual fuel mode. In the present studies the effect of Compressed Natural Gas (CNG) gas induction on the performance on dual fuel engine instead of single Diesel fuel. CNG used as fuel and Diesel or Biodiesel used as pilot fuel on dual fuel mode, Karavera (Thevetia Peruviana) and Surahonne (Calophyllum inophyllum) Biodiesel are used. Dual fuel mode is one of the better methods to control emissions from CI engines and instantaneously replacing existing diesel fuel engine. Experiments is carried out under engine laboratory condition, analyze the performance and emission characteristics of single cylinder CI engine on dual fuel mode by using CNG as fuel and Diesel or biodiesels (Karavera and Surahonne) pilot fuels by varying injection timing 230, 260 and 190 bTDC. Brake Thermal efficiency and Brake specific fuel consumption at dual fuel mode of CNG fuel gives better results than pure diesel fuel engine at all engine loads. The reduction in CO and HC emissions on dual fuel mode for all loads and also peak pressure rise. By 70% CNG fuel substitution rate.
