Engine Performance and Exhaust Emission Characteristics of Fuel Oil-Diesel Fuel Mixture in a Single Cylinder Engine

Cost for Diesel fuel is higher in recent years have cause problem to the consumer. It
is necessary to find alternative fuel that is less expensive to be used for generating
power. Fuel oil is a type of fuel that has been identified as a possible alternative
source of fuel to be used for diesel engine. The engine performance and exhaust
emission characteristics based on Diesel fuel and medium fuel oil (MFO) mixture is
the main study in this project. Beside 100% Diesel fuel, a blend of 5%MFO, 10%
MFO, 15% MFO and 20% MFO are used. The suitable viscosity of fuel mixture is
studied as viscosity plays important criteria for the fuel to be used in diesel engine.
Engine performance and exhaust emission of all fuel blends were investigated and
compared with ordinary Diesel fuel in a single cylinder diesel engine without any
modification. The experimental results show that the engine power and torque are
lower than the value obtained from Diesel fuel. As for exhaust emission, adding
MFO do increase CO emission and particulate matter, but reduce the NOx emission.
It is proven that medium fuel oil can be used as an alternative fuel for diesel engine,
with some lose of the engine performance and emission characteristics.
