To be published on 2019-11-21 by SAE International in United States
Currently Automotive industry is looking for sustainable alternate of Conventional fuels. Bio diesel is an alternative fuel similar to conventional or ‘fossil’ diesel. It is produced from vegetable oil, animal fats, tallow and waste cooking oil. Bio diesel is one of the most promising fuel which can not only replace the conventional fuels but also environment friendly in terms of Greenhouse gases emission. Bio diesel can be produced from various sources and can be sustainable fuel for automotive vehicles. In this paper, efforts have been taken to convert existing Diesel engine into Bio diesel compliant engine. For making suitable for Biodiesel operation, modification in Engine Fuel system, filter and Sealing were carried out. Further Engine performance and emission testing were done and results were compared with performance and emission of same configuration Diesel engine.

Characterization of Deposits Collected from Plugged Fuel Filters

KTH Royal Institute of Technology-Botond Csontos, Hanna Bernemyr, Anders Christiansen Erlandsson
Scania CV AB-Oscar Forsberg, Mayte Pach, Henrik Hittig
Published 2019-09-09 by SAE International in United States
Fuel filters serve as a safety belt for modern compression ignition engines. To meet the requirements from environmental regulations these engines use the common rail injection system, which is highly susceptible to contamination from the fuel. Furthermore, the public awareness towards global warming is raising the need for renewable fuels such as biodiesel. An increased fuel variety brings a higher requirement for fuel filters as well. To better understand the process of filtration, awareness of the different possible contaminants from the field is needed. This study used several chemical characterization techniques to examine the deposits from plugged fuel filters collected from the field. The vehicle was run with a biodiesel blend available on the market. The characterization techniques included X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy (FTIR) joined with attenuated total reflectance (ATR) sampling, gas chromatography-mass spectrometry (GC-MS), and lastly thermal gravimetric analyzer combined with FTIR and a GC-MS (TGA/FTIR/GC-MS). In addition the remaining ash from TGA was measured in energy-dispersive X-ray spectroscopy (EDX). Deposits were scraped from the used filter, and prepared for the different…

Experimental Investigation of Combustion Timing of HVO, RME and Diesel Fuel in a Euro6 Car Engine during Transient Driving Cycles

Czech University of Live Sciences-Martin Pechout, David Macoun
Published 2019-09-09 by SAE International in United States
The current targets to decrease greenhouse gases production, to reduce fossil fuel dependency and to gain energy security and sustainability are driving demand on combustion engine fuels from renewable sources. This effort resulted in utilization of first generation biofuels. Unfortunately, these fuels brought new dilemmas and challenges in general, such as food production competition and land use and, in case of fatty acid methyl esters for compression ignition engines, also technical challenges such as storage stability and deposit formation. Utilization of particle filters and sensitive fuel systems are driving effort to develop compatible renewable biofuels which can be utilized at higher than current shares. Hydrotreated vegetable oils (HVO), as industrially produced biofuels, exhibit some beneficial properties compared to traditional fatty-acid methyl esters especially in terms of oxidation stability, injector fouling, energy content and cetane number. The aim of this study was to investigate heat release rates when three neat fuels (diesel, RME and HVO) are utilized in a current passenger car with a EURO 6 diesel engine at a wide range of operating regimes extracted…

Aerospace Fuel System Specifications and Standards

AE-5A Aerospace Fuel, Inerting and Lubrication Sys Committee
  • Aerospace Standard
  • AIR1408B
  • Current
Published 2019-05-24 by SAE International in United States
This report lists documents that aid and govern the design of aircraft and missile fuel systems. The report lists the military and industry specifications and standards and the most notable design handbooks that are commonly used in fuel system design. Note that only the principle fuel specifications for the U.S. and Europe (Military Specifications, ASTM, and Def Stan) have been included within this report. The specifications and standards section has been divided into two parts: a master list arranged numerically of all industry and military specifications and standards, and a component list that provides a functional breakdown and a cross-reference of these documents. It is intended that this report be a supplement to specifications ARP8615, MIL-F-17874, and JSSG 2009. Revisions and amendments which are correct for the specifications and standards are not listed. The fuel system design handbooks are listed for fuels and for system and component design.

Today's fuel injection engineers, designers, and researchers are continually challenged to meet increasingly demanding fuel economy, emissions and performance requirements for gasoline engine-powered vehicles. The availability of established and recognized standards in support of this effort is critical to accomplishing these goals. And the work of SAE's Gasoline Fuel Injection Standards Committee (GFISC) to create and maintain these essential standards, guidelines and recommended practices helps to ensure the success of these efforts.
