Performance and Emission Characteristics of a Diesel Engine Using Supplementary Vapor Fuel (LPG, Gasoline, Diesel) Fumigated to the Intake Charge
Published November 19, 1990 by Institution of Mechanical Engineers in United Kingdom
An experimental study is conducted to evaluate the use of fumigated LPG fuel, or gasoline or diesel as supplementary fuels for a naturally aspirated, four stroke, swirl chamber diesel engine. The supplementary fuel is introduced together with the aspirated air (fumigation) at various proportions with respect to the main diesel fuel, which is injected the usual way. The influence of fuel feed ratios (supplementary/main), in a vast range of loads, on fuel consumption, pressure diagrams, exhaust smokiness, and exhaust gas emissions is investigated, and the differences from the baseline, (operation with main diesel only), are determined and compared.
