Hydrogen Injection in a Dual Fuel Engine Fueled with Low-Pressure Injection of Methyl Ester of Thevetia Peruviana (METP) for Diesel Engine Maintenance Application

Abstract

The present work is mapped to scrutinize the consequence of biodiesel and gaseous fuel properties, and their impact on compression-ignition (CI) engine combustion and emission characteristics in single and dual fuel operation. Biodiesel prepared from non-edible oil source derived from Thevetia peruviana belonging to the plant family of Apocynaceaeis. The fuel has been referred as methyl ester of Thevetia peruviana (METP) and adopted as pilot fuel for the effective combustion of compressed gaseous fuel of hydrogen. This investigation is an effort to augment the engine performance of a biodiesel-gaseous fueled diesel engine operated under varied engine parameters. Subsequently, consequences of gas flow rate, injection timing, gas entry type, and manifold gas injection on the modified dual-fuel engine using conventional mechanical fuel injections (CMFIS) for optimum engine performance were investigated. Fuel consumption, CO, UHC, and smoke formations are spotted to be less besides higher NOx emissions compared to CMFIS operation. The fuel burning features such as ignition delay, burning interval, and variation of pressure and heat release rates with crank angle are scrutinized and compared with base fuel. Sustained research in this direction can convey practical engine technology, concerning fuel combinations in the dual fuel mode, paving the way to alternatives which counter the continued fossil fuel utilization that has detrimental impacts on the climate.

Experimental investigations into engine characteristics fuelled with hibiscus coconut biodiesel and its blends

“…Crude oil is expected to become extremely scarce and expensive [2]. Petroleum based fuels are used in industries, transportation, power plants and agricultural sectors, respectively [3]. Fossil fuels are finite and the use of fossil fuels results in pollution and global warming too.…”

Determination of the sustainability index along with energy–exergy–emission–economic analysis of a VCR diesel engine fuelled with diesel–bioethanol–Al2O3 nanoparticles

“…7 For increased performance, a CI engine is tested in single-fuel and dual-fuel mode with methyl ester of Thevetia peruviana (METP) and hydrogen gas. 8 Using n -butanol as a co-solvent, an experiment was carried out to improve the stability of the ethanol/jatropha biodiesel (JME) mixture. The inclusion of ethanol can lower the BSFC values when compared to JME fuel.…”

Bibliometric analysis, physical properties, and experimental evaluation of additives-diesel ternary blends

“…Due to depletion of fuel reserves, the globe will face a future fuel scarcity (Mujtaba et al, 2021). In order to meet energy demand, the transportation industry used half of all fossil fuels (Marikatti et al, 2020). Transportation sector is the backbone of oil use and it will be responsible for 50% of greenhouse gas emissions by 2030 (Ahmed et al, 2020).…”
