DILUTION OF ENGINE LUBRICANTS BY FUEL

SAE Technical Paper Series, 1920
<div class="htmlview paragraph">Engine lubrication troubles resulting from the dilution of the lubricating oil in engine crankcases appear with increasing frequency, particularly where economy demands the use of cheap grades of fuel. Unless a lubricant not miscible with present engine fuels can be produced, lubricants will steadily decrease in ...

Modeling of a dilute vaporizing multicomponent fuel spray

International Journal of Heat and Mass Transfer, 1987
Abstract A simplified spray environment is used to represent the multicomponent nature of liquid fuels and to examine the sensitivity of their vaporization behavior to the various liquid- and gas-phase models. Liquid-phase models are the diffusion limit, the infinite diffusion, and the vortex.

Dilute Ethanol Fueled SOFCs: A Symbiotic Solution Strategy

ASME 2009 7th International Conference on Fuel Cell Science, Engineering and Technology, 2009
Biofuels have been broached as being more commercially viable under the biorefinery concept wherein multiple product streams enhance overall economics. An example of this concept is presented in which solid oxide fuel cells (SOFCs) and bioethanol are explored in light of the symbiotic pairing of these two promising alternative energy thrusts.

Effect of Fuels and Dilution Ratio on Diesel Particulate Emissions

SAE Technical Paper Series, 1979
<div class="htmlview paragraph">An experimental investigation of the effect of fuel variables and exhaust dilution on diesel particulate emissions from a Caterpillar 3208 direct injection naturally aspirated engine is presented. Three test fuels with widely varying gravity, volatility, aromatic and sulfur content were used.

On Diluted-Fuel Combustion Issues in Burning Biogas Surrogates

Journal of Energy Resources Technology, 2009
This paper describes an analysis of the burning velocity of pure and diluted fuels, with implications for the development and operation of biogas-fueled combustors. Background work in the area of flame stabilization and propagation are introduced from the combustion literature.

WINTER TESTS SHOW GREATER DILUTION WITH HEAVY FUELS

SAE Technical Paper Series, 1924
<div class="htmlview paragraph">Because the analyses of many samples of new and of diluted crankcase oil had not been completed by the Bureau of Standards when the results of the winter tests were reported at the 1923 Semi-Annual Meeting, the report on these dilution data was delayed.

Fuel Property Effects on Oil Dilution in Diesel Engines

SAE International Journal of Fuels and Lubricants, 2013
<div class="section abstract"><div class="htmlview paragraph">Light-duty diesel vehicles that make use of a diesel particulate filter (DPF) generally require periodic active regenerations. This is achieved by late, in-cylinder post-injections designed to add unburned fuel into the exhaust system to raise the DPF temperature and burn off the

Autoignition of Dilute Fuel Sprays Including Detailed Chemistry

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">Autoignition of fuel sprays is of special relevance to compression-ignition engines. The high air temperature in diesel engines leads to heating, vaporization and autoignition of the injected fuel spray; typically part of the liquid fuel vaporizes before ignition occurs so that by the time the mixture autoignites ...

Effect of fuel type on the extinction of fuel and air stream diluted partially premixed flames

Proceedings of the Combustion Institute, 2009
Abstract Previous investigations have demonstrated that the roles of fuel stream dilution (FSD) and air stream dilution (ASD) in suppressing CO2-diluted methane flames are strongly influenced by the level of partial premixing. Herein, we compare this influence for both counterflow and coflow laminar non-premixed and partially premixed flames (PPFs ...

Combustion characteristics of an SI engine fueled with H2–CO blended fuel and diluted by CO2

International Journal of Hydrogen Energy, 2012
Abstract This paper presents further results of the study on fundamental combustion characteristics of gaseous fuels simulated for a biogas produced through a biomass gasification process with a catalyzer. The main work focuses on combustion characteristics of H2–CO blended fuel and the effect of CO2 dilution on it in a spark-ignition engine under ...
