Abstract

The engine performance has been improved by modifying the combustion chamber shape of the diesel engine for dual-fuel operation with liquid fuel and producer gas (PG). The combined effect of gaseous fuel from redgram stalk and combustion chamber type on the emission and performance of blended-fuel of diesel and HOME biodiesel–PG has been investigated. In this experimental study, four varieties of combustion chambers hemispherical (HCC), low swirl (LSCC), dual swirl (DSCC), and toroidal re-entrant (TRCC) were analyzed comprehensively. The results presented that the TRCC configuration with a given nozzle geometry has 9% improved brake thermal efficiency (BTE) and 10.4% lower exhaust gas temperature (EGT). The smoke, unburnt hydrocarbon (UBHC), and carbon monoxide (CO) decreased by 10–40%, but a 9% increase in nitrogen oxides (NOX) emission levels was observed with TRCC. The delay period and combustion period were decreased by 5% and 7%. The fuel replacement of about 71% for the diesel–PG combination with HCC and 68% for the HOME–PG combination with TRCC was achieved.

Highlights

Biomass fulfils different needs of humans as food, fodder, energy, and shelter since ancient days
Experimental results show that the HOME–producer gas (PG) combination with TRCC offers improved performance than all other forms of combustion chambers tested
The function of a dual-fuel engine with diesel/HOME–PG from redgram stalk showed that the performance is considerably affected by the type of the combustion chamber and liquid fuel type

Summary

Introduction

Biomass fulfils different needs of humans as food, fodder, energy, and shelter since ancient days. Biomass-derived fuels for energy applications play a vital role due to their several benefits [1,2,3,4]. Studies on biomass showed that biomass was the primary source of energy in rural areas and more than 50% in the urban areas of India. India has a considerable prospective for bio-derived fuels and agriculture waste which was around 500 million metric tons of biomass per year during the years 2016–17, and the predicted biomass production during the years 2024–2025 will be approximately 1127 million metric tons. The biomass-based power plant’s total installed capacity in India is about 2559 MW, and it was observed that energy from agricultural residues and various woody biomasses was found to be about 1800 MW approximately
