Implementation of a Automatic Dual Fuel Injection system in a CI Engine

The paper investigates the result on the existing diesel engine that can suitably modified to operate on the diesel fuel mode to conserve diesel and also reduce environmental pollution. The conventional fuels, petrol’s and diesel for internal combustion engines are exhausted at an alarming rate, due to increase of vehicle population and also these fuel causes environmental problems. Make these things in mind the diesel engine can be made to run on LPG as well. LPG carburetor is incorporated on the air intake side of the engine. The fuel injection system is also altered so that it injects only pilot fuel. The LPG will be automatically given to the air take of the engine and flow will be varied manually. At higher engine loads, the dual fuel mode is superior to the pure diesel mode of operation.
