High efficiency dual-fuel combustion through thermochemical recovery and diesel reforming

Plasma Reforming of Diesel Fuel

The use of a plasma reformer for the generation of hydrogen rich gas from diesel fuel has been investigated. A system that is normally used for investigating natural gas reforming has been modified in order to investigate the reforming of heavy liquid fuels. The composition of the reformate has been investigated as a function of the composition of the reagents. The use of a one-step reformer/wa...

Combustion Characteristics of a Diesel-hydrogen Dual Fuel Engine

Among the alternative fuels, hydrogen shows great potential in the near future. In the present study, hydrogen utilization as diesel engine fuel was investigated. Hydrogen can not be used directly in a diesel engine due to its autoignition temperature higher than that of diesel fuel. One alternative method is to use hydrogen in enrichment or induction. To investigate the combustion characterist...

The Sootless Diesel: Use of In-Plume Fuel Transformation to Enable High-Load, High-Efficiency, Clean Combustion

The emission of solid carbonaceous particulate matter (i.e. soot) is a world-wide problem that effects both human health and global environmental health alike. Although a number of sources contribute to the concentration of soot in the atmosphere, Diesel engines play a significant role. Diesel engines, or direct-injection compression-ignition engines, are the primary power plant for delivering ...

Combustion and Exhaust Emission Characteristics of Diesel Micro-Pilot Ignited Dual-Fuel Engine

CFD Investigation into Diesel PCCI Combustion with Optimized Fuel Injection

A multi-pulse injection strategy for premixed charge compression ignition (PCCI) combustion was investigated in a four-valve, direct-injection diesel engine by a computational fluid dynamics (CFD) simulation using KIVA-3V code coupled with detailed chemistry. The effects of fuel splitting proportion, injection timing, spray angles, and injection velocity were examined. The mixing process and fo...
