Abstract:
With the increasing environmental legislation and the increasing demand for the
transportation sector, that relies mainly on conventional fuels for operating the engines of its
vehicles, as this sector directly affects the environment through emissions comes a big importance
and responsibility to focus on the fuels that these engines consume and the emissions it produces.
In this project, the LPG dual fuel engine is studied and offered as an alternative fuel system for the
engines to operate on it. Using both alternative fuel Liquefied Petroleum Gas (LPG) and
conventional fuel gasoline in Spark ignition engine (SIEs), which is modified to be able to use the
Gasoline as a primary fuel to warm up the engine and the LPG with a variation mixture in all time
of action. The LPG dual fuel engine has a good thermal efficiency partially for low load and speed,
the performance and emissions are mainly varying depending on these two factors, so this fact raises
a challenge to reduce the emissions produced as much as possible when using the LPG dual fuel
engine with in / out Exhaust Gas Recirculation (EGR) system, which is used to reduce Nitrogen
Oxide (NOx), Carbon monoxide (CO).
The approach will be studied and tested theoretically and practically to find the optimal outcome for
the LPG dual fuel through this project.
Key words: Gasoline, LPG, dual fuel, Environment, Economy.
