Description

Dual-Fuel Diesel Engines offers a detailed discussion of different types of dual-fuel diesel engines, the gaseous fuels they can use, and their operational practices. Reflecting cutting-edge advancements in this rapidly expanding field, this timely book:

  • Explains the benefits and challenges associated with internal combustion, compression ignition, gas-fueled, and premixed dual-fuel engines
  • Explores methane and natural gas as engine fuels, as well as liquefied petroleum gases, hydrogen, and other alternative fuels
  • Examines safety considerations, combustion of fuel gases, and the conversion of diesel engines to dual-fuel operation
  • Addresses dual-fuel engine combustion, performance, knock, exhaust emissions, operational features, and management
  • Describes dual-fuel engine operation on alternative fuels and the predictive modeling of dual-fuel engine performance

Dual-Fuel Diesel Engines covers a variety of engine sizes and areas of application, with an emphasis on the transportation sector. The book provides a state-of-the-art reference for engineering students, practicing engineers, and scientists alike.

Reviews

"… a comprehensive and well-integrated review of the relevant fundamentals and practices of the operation of gas-fueled compression ignition engines of the dual-fuel type. … a very well-written book featuring interesting, reach-in information covering important topics of internal combustion engines not covered yet in a single book. … excellent, up-to-date … a very good and unique source of information on dual-fuel engines for engineering students, practicing engineers, and scientists. The book reviews the latest and possible future developments in the area of dual-fuel engines."
