Innovative Survey on Dual Fuel Engine with Fuel Essences

Abstract

Alternative fuels have been getting more attention as concerns escalate over exhaust pollutant emissions produced by internal combustion engines, higher fuel costs, and the depletion of crude oil. Various solutions have been proposed, including utilizing alternative fuels as a dedicated fuel in spark ignited engines, diesel pilot ignition engines, gas turbines, and dual fuel and bi-fuel engines. Among these applications, one of the most promising options is the diesel derivative dual fuel engine with natural gas as the supplement fuel. This study aims to evaluate diesel and dual fuel combustion in a di ethyl eater-diesel dual fuel engine. More dual fuel engines are being utilized due to stricter emission standards, increasing costs of diesel fuel and decreasing costs of di ethyl eater. Originally sold as diesel engines, these units are converted to di ethyl eater-diesel fuel engines using an aftermarket dual fuel kit. As di ethyl eater is mixed with diesel, the amount of diesel used is reduced. The maximum di ethyl eater substitution is limited by knock or emissions of carbon monoxide and total hydrocarbons.
