Abstract
This paper presents the performance and emission behaviour of a spark ignition engine run
on groundnut oil blended lubricants. However, for the purpose of comparism, benchmark
tests were carried out on multigrade and monograde motor oils. A 5.0 h.p engine test-bed
incorporated with an A.C dynamometer and flue gas analyzer was used to conduct the tests.
At maximum engine speed, the groundnut oil blended lubricants generated an exhaust
temperature of 6.02% higher than multigrade oil, and 6.26% higher than monograde oil. The
brake power was 12.70% and 10.94% higher than the monograde and multigrade oils. In
terms of fuel economy, the monograde and groundnut oil blended lubricants are 7.50% and
2.18% higher than multigrade oil respectively. It is shown that as the proportion of viscosity
modifier in the oil sample increases, exhaust temperature, brake power, brake mean effective
pressure (b.m.e.p) also increases, while the specific fuel consumption diminishes. At various
speeds, CO2 level emitted by the use of groundnut oil blended lubricants was observed to be
higher than it was the case for multigrade and monograde oils. In the light of the fast
depleting fossil fuel reserve in Nigeria, this work has demonstrated the feasibility of using
groundnut oil blends as lubricant substitutes in spark ignition engines.
