Detailed study on the effect of different ignition enhancers in the binary blends of diesel/biodiesel as a possible substitute for unaltered compression ignition engine

Abstract

This study examines the impact of the oxygenated additives namely DTBP (Di-Tetra-Butyl-Phenol) and 1-Pentadecanol (1-DEC) on emissions, combustion and performance patterns of Karanja biodiesel/diesel blends. Two additives were selected as ignition improver owing to their improved physicochemical properties. The additives were mixed at 10% volume with the equal blends of diesel and biodiesel. Experimental results revealed that by adding additives and biodiesel to diesel found no phase separation. HRR and peak pressure were highest for diesel and least for KBD/D blends. However, blending the additives enhanced its HRR and peak pressure. Addition of additives lowered the harmful emissions significantly with a slight increase in NO emissions to the KBD/D blends. In addition, a noteworthy increase in performance aspects was observed for KBD/D blends by adding DTBP and 1-Pentadecanol.

Influence of N-Butanol-Diesel Fuel Blends on the Performance Characteristics of a Four Stroke, Compression Ignition Engine

“…have emerged as promising replacements for traditional fossil fuels due to their biodegradability, renewability, and ecofriendliness [5,6,7]. Alcohols such as n-butanol have attracted considerable attention for their potential to partially substitute fossil fuels and produce cleaner combustion [8][9][10][11][12].…”

Ignition Investigation of Pure Biodiesel in A Research Engine with Dual Fuels

“…The addition of a higher proportion of beef-tallow biodiesel reduces the smoke, CO, HC, and Nitrogen Oxide (NO) discharges of biodiesel/diesel combinations substantially. Devarajan et al, [6] investigated a CI engine's exhaust pattern powered by grape seed biodiesel. It was feasible to cut NO emissions by 4.2% by adding 20% grapeseed biodiesel to fuel.…”

Investigation of Dual Fuel with Bipartite Additives in CI Engine

“…Non-edible oils like Jatropha, Neem, rubber, palm, waste cooking are to be a feasible feedstock for biodiesel and oil those are available widely. To convert Jatropha and waste cooking oil into biodiesel by transesterification by supercritical methanol conditions in that FAME yield was achieved >90% at 350°C by using heterogeneous catalyst to reduce reaction time, high triglyceride conversion [4][5][6].Convert edible oil to biodiesel by transesterification process using homogeneous catalyst like hydrochloric acid, sulphuric acid ,sulfonic IOP Publishing doi:10.1088/1755-1315/1100/1/012015 2 acid, organic sulfonic acid and ferric sulphate but its comparatively long process than heterogeneous catalyst. Homogenous catalyst are not recommended due to more wastages occur than heterogeneous catalyst [7][8][9].…”
