About thirteen years ago, the Society of Automotive Engineers (SAE) was seeking a book for their Technology Profiles series on the subject of diesel common rail. Along with my co-author, Professor Ming-Chia Lai from Wayne State University, Detroit, we were invited to submit a manuscript for this opportunity which was accepted for publication in 2005 under the title “Diesel Common Rail and Advanced Fuel Injection Systems”. As SAE publication T-117, it is still in print.

Loosely related to this book for the SAE, I have also been an Instructor on diesel injection technology for the SAE Diesel Engine Engineering Technology Academy which is an excellent forum for learning about this subject matter.

In 2007 I was invited to author a chapter on the subject of injection systems for heavy duty diesel engines, to be included in a compilation under the editorship of Professor Hua Zhao of Brunel University in the UK. With the title
Direct Injection Combustion Engines and Their Fuels for Automotive Applications in 21st Centurythe book contains around 30 chapters each authored by a distinguished practitioner in their particular field, and was published in early 2010 by Woodhead Publishing Ltd., now a part of Elsevier.

One of the Southwest Research Institute Clean Heavy Duty Diesel Engine Consortium projects with which I was actively involved was the Real Time Water Emulsions (RTWE) evaluation work. In this program, Diesel Systems conceptualized and supplied a unit injector based fuel system that was able to inject a water-fuel emulsion wherein both the water and fuel quantity (and therefore the ratio between the two) could be modulated independently as a function of load or any other criteria. The objective was to make a positive impact on NOx and particulate matter (PM) emissions while minimizing the quantity of water consumed. In this we were successful, and at the same time a small improvement in fuel consumption was recorded. At least one patent and two technical papers came out of this work:

      • Cycle-Controlled Water Injection for Steady-State and Transient Emissions Reduction from a Heavy-Duty Diesel Engine", Rudolf H. Stanglmaier, Philip J. Dingle, Daniel W. Stewart, ASME ICEF 2004-825, Oct. 24 2004.


      • "Effect of Diesel and Water Co-Injection with Real-Time Control on Diesel Engine Performance and Emissions”, Christopher J. Chadwell, Philip J G Dingle; SAE Paper No. 2008-01-1190, April 17 2008.
