CONTENTS Introduction Conversion of Petrol Engine to gas engine Conversion of Diesel Engine to Dual fuel mode Conversion of Diesel Engine to 100 % Biogas (S.I.Mode) Conclusions Technology Developed By Indian Institute of Technology Delhi Under MGIRI Project (Prof.R.R.Gaur) Mahatma Ghandhi Institute of Rural Industrialisation Wardha with Dr. G.P.Govil MOTIVATION To provide power in each house from renewable source of energy in villages To provide drinking water in villages To create employment in rural areas To have sustainable growth To provide an affordable conversion kit to convert diesel engine to gaseous engine on site Concept for Domestic Power Supply in Rural Area Balloon Biogas Digester Biogas Storage Balloon INVERTER Biogas Generator . Power Need Village Household requirements Dairy requirement Village cluster requirements 1-10 KW 20-50 KW >100 KW . CONVERSION OF PETROL ENGINE TO GASEOUS FUEL ENGINE . 5 More Wear & Tear because of less lubrication Conversion Leads to DERATING of engine .7-9. Natural Gas. Producer gas CR=10-12 Petrol CR=7. Biogas.Conversion of Petrol Engine to Gaseous Engine Gas –Air Mixing Compression Ratio LPG. Reasons for Engine Derating Lower calorific value of Biogas Lower volumetric efficiency Higher spark advance due to lower burning rate of Biogas . Conversion of Diesel Engine to Gaseous fuel Engine . Modification of Engine-Dual fuel Mode Using Diesel Gas Carburettor Arrangements for supply of Diesel . Dual fuel operation (Gas+ Diesel) Ignition by pilot fuel injection (Diesel) . DIESEL DIESEL INJECTOR VENTURI BIO – GAS DIGESTER AIR FILTER ENGINE FUEL PUMP GOVERNOR GAS CONTROL VALVE FUEL FILTER MANUAL GAS CONTROL VALVE Schematic Diagram for Conversion to Dual Fuel Mode using Diesel and Biogas . .Problems associated with DualFuel Engine Dual Fuel needs Diesel The Fuel Injector gets over heated when Diesel flow is reduce to 10 to 15 % It is more severe with purified Bio-gas (Methane 95 %) Check for injector nozzle.
