Emission Measurement Analysis of Sapodilla Seed Oil Blending Fueled IC Engine

Abstract

This present work focused on investigating the thermal behavior and emission level of sapodilla oil mixed with diesel to an internal combustion (IC) engine. The behavior of the engine is measured via brake thermal efficiency (BTE), brake-specific energy consumption (BSEC), heat release rate (HRR), cylinder pressure, and cumulative heat release rate (CHRR). The test results were evaluated with diesel fuel. Carbon deposits were low in sapodilla seed oil with slight variation of calorific value than standard diesel fuel. BTE value for case B20 is found to equal diesel fuel. For lower and higher blends, the cylinder pressures are lower than the diesel fuel. HRR decreased as increased of the blend ratio. Inferior blends of sapodilla are emitted lower HC and CO. The BTE of B100 works 88.13% efficiently, similar to diesel for low load conditions. When compared to diesel, a maximum NOx reduction of up to 30% was achieved while using the sapodilla blend. It is found that the oil derived from the sapodilla seed kernels will be the promising additive for fossil fuels for a greener environment.

“…In another study using jatropha (70 °C), a 5.18% reduction in thermal efficiency was observed in the maximum power condition (PRADHAN et al, 2014). When using sapodilla (Manilkara zapota) oil, an 88% thermal efficiency was reported in relation to PD (PRABU et al, 2021).…”

“…Eficiência térmica de 28,51% para o PD e de 27,69% para o óleo de pinhão-manso a 100 °C , também utilizando pinhão-manso (70 °C), observou-se redução na eficiência térmica em 5,18%, em condição de potência máxima (Pradhan et al, 2014). Com utilização de óleo de sapoti (Manilkara zapota), foi relatado eficiência térmica de 88% em relação ao PD (Prabu et al, 2021).…”
