A Study on Dual Fuel Engine Combustion and Emissions

Optimizing combustion efficiency in dual-fuel engines

Abstract

Latest research has been carried out into the introduction of a dual-combustion approach to increase the heat efficiency of internal combustion engines while reducing their emissions at the same time. Compression ignition (CI) motors use double-fuel combustion to facilitate the use of more easily accessible gas oils or modern combustion methods. In this study we have studied about the dual-fuel compression-ignition engines, effects of exhaust emission, conventional dual-fuel compression-ignition engines, advanced dual-fuel compression-ignition engines, dual-fuel spark-ignited engines which is concluded that in compression ignition (CI) engines, Dual-fuel combustion provides an efficient solution for timing and extending engine load limits to regulate combustion. To this end, both a high and low-reactivity fuel is inducted, the concentration is adjusted to one another and hence the reactivity of the fuel mixture is optimized under various operating conditions (on a cycle-by-cycle basis).
