A Study on Smoke Reduction in Diesel Engines Through Organic Fuel Additives

Abstract

In addition to industrial applications, diesel engines find wide
use in power vehicles due to the economy over gasoline engines.
Some earlier studies on diesel engine emission control employing
metallic additives are briefly reviewed. Considering the formation
of undesirable toxic combustion products by the deposits left by
the metallic additives, the authors have in the present study examined,
rated and reported the smoke reduction characteristics of eight
non-metallic organic compounds (one non-oxygenated and seven
oxygenated). The effects of additive concentration and the engine
load per cent are outlined. The test results are promissing. However,
further studies are required to evolve ideal additives and to better
understand the smoke reduction mechanisms.
