This document summarizes a student project to operate a diesel engine using both diesel fuel and liquefied petroleum gas (LPG). The project aims to utilize the compression ignition properties of diesel to ignite LPG, allowing a diesel engine to run on both fuels. Key findings include that this approach could provide cost savings by reducing dependence on fuel price fluctuations and allow the use of biofuels. Testing showed the engine generated 16 horsepower but further work is needed to reduce knocking and optimize the fuel mixture. Overall, the project demonstrates the potential for dual-fuel engine technology but more testing and advancement is still required.

3. Project Summary
 Introduction
 What we achieved out of it ?
 Basics of our project
 Working of the Engine
 Results of our Project
 Present & the Future

4. introduction
 It is an experimental Project which identifies
the scope of utilization of compression
ignited and spark ignited fuels in a single
Engine
 The compression Ignition properties of
fuels(liquid) like diesel is utilized to Ignite
fuels(gaseous) like LPG and then power the
engine

6. advantages
 The Diesel Engines can be changed into a gas
Operating engines thus it can create a cost
effective way of adopting new technology
 This approach decrease the variation in
different fuel costs to create a uniformity in
different fuel prices that stabilizes economy
dependence on fuels
 Environment friendly because of a scope to
replace diesel and LPG with bio diesel and
biogas
